Use plastic plugs for pipes of various types: round and profile. The purposes of their application are as follows:
- For covering end openings of different types of pipeline. Stubs can be temporary or permanent.
- For the manufacture of various containers under pressure: boilers, pneumatic and hydraulic devices, vessels.
- To avoid internal damage during pipe transportation.
Plastic plugs allow to protect pipes from debris and moisture getting into them, protect from damage of various nature. For profile pipes, the use of a plug is the best way to seal the posts, for example, when making a fence. They are used not only for pipes, but also for other holes in various structures, which are used as decorative or supporting elements.
Plastic plugs for pipes are easy to install, economical and have a wide range of colors, shapes and sizes.
Types of plastic plugs
Caps for profile pipes are available in different shapes: rectangular, square and round. Square end caps are used for square profile pipes. The stiffeners of these plugs can be straight or tapered. Basically, they are placed in shaped pipes, from which fences are made. You can order any standard standard sizes of these products from us.
Rectangular plastic plugs do not fundamentally differ from square ones. They are also used for shaped pipes. Round plugs have different diameters and several stiffeners. They are made of high quality plastic with excellent elastic properties. Therefore, these products perfectly resist temperature extremes and various atmospheric phenomena, are distinguished by their durability and high wear resistance. We offer plugs of all existing diameters. A wide variety of colors and sizes, low cost will allow you to make the best choice.
For sealing support posts, round plugs - the best option... They will not only protect the poles from adverse effects, but also give them an attractive aesthetic appearance.

Plugs can perform several functions for pipes at the same time. It should be noted that these devices can be performed both as an aesthetic element and as a functionally significant part of the pipeline. So, you need to figure out in what cases it is necessary to install plugs.
When stubs are used
For example, stubs can be used to sewer pipes... The element is installed in such cases:
- to prevent debris and other foreign objects from entering the pipe. Most often, a plug is placed when wiring. If you can install a shut-off valve on the water supply, then plugs are placed on the sewer pipes;
- if part is dismantled sewerage system, then it is necessary to put a plug. After that, it will be possible to disassemble some parts of the system, while not violating the integrity of the entire system;
- in some cases, a pneumatic plug is installed. It is needed to eliminate accidents at various sections of the system of all types of communications. The plug can be installed for a gas pipe or for a water supply.
Types of plugs
Currently, a large number of plugs are used in plumbing. The most common stubs are worth highlighting:
- threaded. This is the most common plug found in every home. They can be installed both on the water supply system and on gas pipes. Basically, threaded plugs are made of steel. In this case, the thread is made both external and internal. Basically, threaded plugs are installed on pipes with a diameter of no more than two inches. Please note that the installation of threaded plugs is performed using a special linen or FUM winding. Linen roll is considered the most effective. It is not recommended to use a sealant, as it will complicate the removal of the plug if necessary;
- flange plugs. They are used on pipes over two inches in diameter. A blind flange is a flange without a hole that is bolted to the pipe. Rubber is used as a gasket. If hot water flows in the pipe, then paronite is used;
- spherical plugs. Such products are used in critical communications, where the pressure can reach one hundred atmospheres;
- pneumatic plugs. They allow for a short time to limit the integrity of the system in certain areas. These plugs are made of rubber. When air is pumped into them, they increase.
Plastic pipe plugs
Plastic pipe plugs can be used in sewerage or plumbing systems. In each case, plastic plugs help to solve specific problems.
In general, a plug is used to seal a side hole in a pipe. It is clear that the pipeline can be welded or completely removed the section of the pipe, which has to be closed with a plug.
However, plastic pipes are a material that allows you to change the architecture of the system at any time. For example, then you will need to install some kind of plumbing fixture, powered by a pipe, on which there is now a plastic plug.
If the system has no pressure, then the plug can be used as a window to access the network. For example, in a sewer riser there may be plugs through which the pipe can then be cleaned. In other cases, you will have to install plastic plugs for other purposes and in different ways.
Installing a blanking plug in a system without pressure
If there is no pressure in the pipes, then the actual pressure in them is one atmosphere. The plug is then used to seal the system. The plug is mounted by means of fixing the end in the socket. A sealing ring is placed on the socket. Next, the plug is firmly inserted into the socket itself. And this can be considered the completion of the installation of the plug.
Installing a plug in a pressurized system
The system, which works under pressure, is assembled from durable polypropylene pipes... Therefore, the plug must not only be airtight, but also strong enough.
Therefore, plastic plugs must be installed on the thread or for welding. In some cases, the plug is fixed with glue. But if the plug is installed on welding or glue, then it will be almost impossible to disassemble the system. At the same time, the threaded connection can be easily opened at any time.
If the plug is firmly attached, the following operations must be performed:
- use diffusion welding. In this case, a special tool heats the inside of the plug and the outside of the pipe. Then the plug is firmly pressed onto the pipe;
- on the glue. The adhesive is applied to the plug and pipe. Then the surfaces are joined and kept for about half a minute.
Thus, a rather strong and sealed plug is obtained, but it will be impossible to remove it.
Installing the plug with further dismantling
In such a situation, the most common way is to mount the plug on the thread. It is cut into a pipe. As a rule, there is already a thread on the plug (on the inside). But such stubs are used on special channels, which imply their further revision. For example, this technology is used in sewer pipes.
Metal plugs for round pipes
Metal plugs for round pipes serve the same function as plastic plugs. Steel plugs can be used on all pipes that pass through the industry and in the home. The metal plug is made according to the template based on finished products by stamping.
The metal plugs can have a diameter of 32 to 1020 millimeters. They can withstand high pressure and temperature.
Metal pipe plugs are available in elliptical, flat and flanged designs. The elliptical plug is made of stainless steel. It can withstand various temperatures as well as aggressive environments. Therefore, this product is used for pipelines in the chemical industry, pharmaceutical and food industries.
A flange plug has similar properties, which is used for the same purposes as the previous type of products. Flat plugs are also used for the pipeline, but they can withstand a maximum of 80 degrees. Such products are produced with a diameter of 57 to 1020 millimeters.
Plugs are made of durable alloy or stainless steel. But low-alloy steel is also often used, which has high strength characteristics.
Metal plugs for round pipes have several advantages:
- excellent resistance to high temperatures, pressure and aggressive environments;
- provide the strongest connection;
- the possibility of dismantling at any time.
The plug is a very necessary element in any communication system. It allows you to open the system at any time and connect any consumer to it. The exception is plugs, which are attached to welding or glue. In general, the stub can ensure the full operation of the system without removing part of it.
Plugs belong to the connecting parts of the pipelines, they cover end holes or gaps. This type of fitting is indispensable in pressure vessels. The SantekhArsenal online store offers certified high quality products. Replenishing the assortment, we carefully monitor that each product meets the requirements of GOST. The products are not suitable for drainage.
Benefits of steel products
When installing water pipes (but not sewer pipes), steel plugs are used. Elliptical seamless products are made from 2 types of steel: low alloy or carbon steel. It can withstand enormous pressure and is therefore suitable for closing openings in vessels and boilers. Steel products are able to withstand temperatures in excess of 450 degrees Celsius, they do not corrode and do not deteriorate with constant contact with water.
In our catalog you will find stubs made of steel, not only Russian, but also of foreign production. Products of European brands are created according to the German standard, but their size range is almost the same as that established by the domestic GOST. All products are guaranteed.
The SantekhArsenal online store is an opportunity to buy plugs for pipes and boilers with free delivery in the capital. We send orders to other regions, transferring them to the reliable hands of transport partner companies. Need help choosing? Our managers will be happy to answer your questions!
When repairing water supply networks, situations are possible when some sections of the old pipeline remain completely unused and need reliable blocking. Find out how to muffle a pipe by studying the material posted in our article.
Blocking methods
The simplest and most reliable way to seal pipes is to prepare the thread at their end and install a plug of a suitable diameter. Some home craftsmen advise in such a situation to use a metal bolt of the appropriate size, which is hammered into the hole, and then scalded around the circumference of the pipe. However, the use of these techniques is possible only if the end part of the metal pipe is in a satisfactory condition.
In the event that the state of the blocked area is assessed as "dilapidated" - you will not be able to use the options listed above. In this situation, the proven "old-fashioned" method is used, which involves driving a wooden plug of the appropriate size (the so-called "chopik") into the pipe hole.
It is recommended to make such a "plug" from waterproof wood, which is treated with resin to protect it from decay. Some time after driving into the pipe, the chopik swells and reliably blocks the hole from leaks. As for plastic pipes, it is not recommended to use wooden plugs to plug them.
Sealing plastic pipes
Immediately, we note that there are two types of sealing plastic pipes: permanent and temporary. The choice of one or another blocking method is determined not only by the pipe material, but also by the state of the entire pipeline as a whole.
So, temporary sealing is used when access to the pipe is difficult and involves the use of a special polypropylene plug with an internal thread. Before installing it using a plate of the appropriate size on plastic pipe an external thread is cut.
Note! To permanently block the plastic channel, it is best to use a special welding device (soldering iron). The adhesion of elements in such a compound is carried out at the molecular level, which provides it with the necessary strength. We also note that with the help of a soldering device, you can also fix an ordinary plastic plug on the pipe.
Materials and tools
For blocking work water pipes of any kind, you will need the following tool and consumables:
- a hacksaw for metal or the so-called "grinder";
- file (rasp) for removing burrs from the ends of pipes;
- sharp assembly knife;
- threading device (if necessary);
- plugs and screw plugs used for temporary and permanent blocking of pipes;
- silicate glue (sealant);
- a welding device with a set of nozzles or a hair dryer (for sealing plastic pipes).
In conclusion, we note that blocking the end holes of pipes, as a rule, does not require special skill from the performer. At the same time, almost all working tools (with a few exceptions) are always available in any household.
Plugs are used on pipes for a wide variety of tasks. In the oil and gas industry and work with pipelines, one cannot do without them, because with their help it is possible to emergency shut off the main or part of it, reliably close the holes at the ends of the pipes and bends.
Use such important parts for example for the safe transportation of rental goods or even in as decorative ornaments on finished structures. They give an aesthetic and finished look to the assembled product.
Types of plugs
Modern manufacturers produce a huge number of plugs. They are usually divided into types according to several differences. technical parameters. First of all, attention is paid to the design features of the end plugs and their material.
By design features, such products are divided into the following types:
- Threaded plugs used for pipes are designed to be used in conjunction with fittings and pipelines with threaded connections. It is very simple to mount such a plug, and reliable tightening of the thread allows you to forget about the possible breakdown of the section. Such parts are sold for $ 1-1.5;
- Pneumatic pipe plugs areare made of rubber. She is durable an inflatable rubber ball complete with a small pump attached to it. When pumped with air, the pipe plug expands, then completely blocks the hole. Spherical rubber plugs are priced at $ 10-20 for the simplest samples. Industrial equipment for blocking large pipelines may well cost from several hundred dollars;
- Transport pipe plugs have the form of a boot or cap, and a very simple one-piece design with adjustable mechanical fasteners, which is quite reasonable. After all, the task of these parts is to simply shut off the pipeline during transportation, at this time they are exposed to minimal loads. Transport covers for profile pipes are sold in stores for 20-50 cents;
- Elliptical plugs are made from sheet steel by stamping. Such plugs are considered permanent, they are mounted by welding, for example, on a gas pipe. They can be purchased for 40-80 cents;
- T the end cap for the pipe is used for the simplest tasks, when you just need to cover the end of the steel supports, that is, to prevent debris, moisture, etc. from getting inside. End decorative parts are a type of shipping, and therefore their price is approximately identical and equal to 30-60 cents;
- A pipe flange is a steel or rubber plate with cut holes for fixing bolts or rivets. The holes fit exactly the flange itself, so fixing is very easy. Product price for steelpipes of this type are at the level of 5-15 dollars. Changes in price are due to differences in thickness, dimensions, and material of the part itself.
By type in the material used, they are divided into the following types:
- The metal pipe plug is made of steel or brass. It all depends on the specific product and its purpose. Metal samples are strong and reliable, but corrosive and rather laborious in terms of installation, for example, on water pipelines;
- Polymer samples are made from durable polyethylene or lightweight plastic. Polyethylene decorative corks have a very low cost, at the same time they also do not react at all to corrosion. However, upon contact with direct sunlight, they are gradually destroyed;
- Chrome decorative ends are a kind of metal, but they are distinguished by an external beautiful shining appearance. Usingthey are mainly used to give pipes a decorative effect;
- Rubber models och they are very plastic and work as a protection against debris and dirt. They are not suitable for serious blocking of water pipelines, since the process of their installation consists in the usual pushing of the plug in the required area with the help of physical force.
Requirements depending on the characteristics of the pipes
Such parts are selected so that they exactly correspond to the features of specific pipelines. Moreover, both the material and its functional purpose are taken into account.
For example, a plug for a gas pipe must be extremely sturdy and reliable. Moreover, gas slightly surpasses water in its structure, and this already leads to increased requirements for sealing areas. Regular threaded samples or pneumatic plugs on the gas pipe will not work... It is better to install them on water pipes or other pipes.
For heating systems and hot water pipes are not recommended to take plastic and rubber products, as they can be damaged when high temperatures... In this case, quality metal is needed.
If necessary, block any type of opening on long time, use elliptical no or flange pipe plugs.
The shape and profile of the highway also has an impact. In this case, the main requirement is full compliance with the dimensions of the pipe plug and its shape.
For example, a stub for shaped pipe 80 × 80 mm should have the same dimensions and completely cover its profile. Therefore, before you buy a product for
i have such uses, you need to make sure you make the right choice.
The shape of the edge also influences the fastening requirements of the end caps. Square pipe plugs cannot be attached using threads or flanges. They can only be welded or pushed mechanically.
Accordingly, it is very important to make sure that with such a fastening the part holds well and is capable of performing its functions.
Caps for round pipes, in terms of application, are much more functional. Which, however, is completely unsurprising. After all, it is pipes with a round profile in 95% of cases that are used to equip water mains and supply systems. Here, requirements are already imposed not on the type of fastening, but on its quality and simplicity.
Using pneumatic plugs (video)
It is almost impossible to name specific generic types or types of stubs. There are too many of them on the market today.
Inflatable e pneumatic plugs for trubles are chosen when you need time immediately block any type of connection. They are convenient for their functionality, since the inflatable spherical balloons take the form of a pipeline.
Flange and elliptical plugs on steel tubes they are fastened most often, since they correspond to them in terms of the material being manufactured and the type of construction.
However, if 80 × 80 pipes are used not as pipeline elements, but as components of metal structures, then in such a situation the choice of conventional end caps will be correct.
Plastic covers - plugs for metal pipes are used only as transportation, or to prevent atmospheric precipitation with debris from entering the openings of structures, since they are not able to qualitatively block the channel.
Screw plugs are good for their stable strength and the absence of any problems during installation, however, they should be bought only if inside or outside the edge already the thread is cut. Moreover, this thread must fully correspond to the one that is already on the plug. This refers to the type of thread and its direction.
When choosing protective-blocking torus end elements for profile pipes always pay attention to their shape. As a rule, profilepipes are not used as water supply, heating or transportation systems.
AND they often do metal fences, furniture, fences or equipment frames. Therefore, the plug for a profile pipe 80 × 80 mm is primarily assessed by its dimensions and shape, and then by all other factors. Spherical plugs in shape for pipes are absolutely not suitable, rectangular or square are required.
It is also desirable to follow from the principle that the material of the selected element should be compatible with the material of the pipeline, or at least not conflict with it. For example, a plug for a plastic pipe made of plastic will last longer, and it is much easier to install it.
However, this rule has a number of exceptions. A metal-plastic main can transport hot water, and polyethylene samples are not able to interact qualitatively with such a carrier... In this situation, you will have to think about how to connect metal-plastic pipes and spherical rubber or metal parts.
In the end, you can even block the hole yourself, since you can make a simple plug yourself. Such a structure is useduse of polyurethane foam and ordinary silicone sealant in two layers. A more traditional and even old-fashioned way is the use of dense wood and resin.
