Caps for different types of pipes (metal, plastic) is one of the most popular types of fittings. They can be used not only in the classic silencing of pipelines, and to protect products when used for other purposes. Caps are available for profile, and for round pipes. These details differ in the material of execution, example, plastic or metal, and size.
Caps for rectangular pipes are used for technical and decorative purposes
Assignment of caps for profile pipes
The main purpose of the plug for the pipe is to cover its end holes. In this case, the use of the part can be worn as temporary (for the period of repair work), and permanent.
Also metal or plastic, round or profile plugs are used in the manufacture of industrial containers, working under pressure. These can be various pneumatic and hydraulic vessels and devices, boilers.
An important purpose of plugs is to cover the pipes during their transportation. This way you can avoid damaging the inner surface of the products. From plastic the cap on a profile pipe allows to protect a design from undesirable hit of moisture, various garbage, and also to protect from any influences of mechanical character.
Caps for profile pipes are made of metal and various polymers
Plastic and metal plugs are widely used for sealing pipes, which is a structural element of the fence. They can also plug holes in furniture.
Materials for production
Silence elements almost always correspond to that material, from which the pipe is made. Metal plugs are often made of stainless or plain steel, aluminum, alloys of non-ferrous metals. Welding is not always required for their installation.
pay attention! The simplest type of steel part is an iron plate, which can be adjusted by the hands to the size of a profile pipe and then welded.
Another type of material is a polymer (polyethylene, polypropylene, polyvinyl chloride). Polyethylene is the most popular for making caps. Polyvinyl chloride parts are used for pipes, having a wall thickness of more than one millimeter, and withstand temperature fluctuations in the range -30 — +60 degrees.
The most expensive are chrome elements. They are most often used in furniture decor, equipment, sports simulators.
Types of muffler elements for profile products
Caps are selected based on the material of the existing pipe. Polymer elements are used for plastic products, however at small diameters and low value of pressure on the pipeline from metal it is possible to put a polyethylene detail.
In decorative elements, the plugs are often fastened by welding, to make the pipes look, as a whole
Metal plugs for profile pipes are mostly muffled steel structures.
The elements differ in the method of their fixation. So, distinguish plugs for pipes:
- spherical;
- flanged;
- rotary;
- flange boundaries;
- elliptical;
- flat welded.
Steel elements on the profile pipe can withstand temperatures up to 600 ?WITH. in addition, they are resistant to aggressive environments and have different shapes (square, oval, rectangular, etc.).
According to the place of application, the plugs are divided into external and internal. Plastic plugs for profile pipe, has a square cross section, are made only of external type. Similar elements for rigid products from polyvinylchloride happen and external, and internal.
Plastic parts are most often used in the home as a fitting for silencing pipes without the use of welding. They have a number of stiffeners, which provide reliable fastening. Due to their shape, converging cone, significantly facilitates entry into the pipe.
Plastic plugs do not require welding, they are simply inserted into the pipe and securely close the cut
Manufacture and special types of caps
Plastic plugs, usually, are made by pouring under pressure. This method is the most popular t. to. allows you to produce large batches of items in a relatively short time.
pay attention! Details for a profile pipe are made with introduction of recycled composite materials. This allows you to reduce costs without losing product quality.
There are some special types of plugs, which are applicable for professional purposes:
- plug of pneumatic type;
- mechanical;
- oil-petrol resistant.
The first type of elements is divided into multidimensional, high temperature, with standardized diameters, etc.. d. The cap for the second type of pipe is made of steel, aluminum, plastic and can be chemically resistant, with locks for wells and more. Special plugs are also available separately, designed for pipelines, operating under pressure from 10 to 25 atmospheres.
Characteristics of plastic plugs
The plastic cap differs in simple and fast installation by its insertion in a pipe or a rack. Over time, it does not lose color under the action of ultraviolet radiation and temperature changes. Such products can last about seven years, providing excellent sealing. Preventing water ingress and accumulation of debris inside the product protects it from corrosion.
In the pipes, employees support for the fence, garbage and water can accumulate, which leads to the destruction of the metal, that is why you need to use plugs, the end is closed
External elements, in addition to creating a seal, protect not only the end of the pipe, but also up to five centimeters of the surrounding area. Internal plugs are inserted into the product completely, however, their cost is higher.
The main dimensions of square parts are: 150x150; 140x140; 120x120; 100х100; 80x80; 70х70; 60x60; 50x50; 40x40; 30x30; 25x25; 20x20 and 15x15. Rectangular plugs usually have the following parameters: 100x120; 80x120; 80х100; 60x120; 60х100; 60x80; 50х100; 40х100; 40x80; 40x60; 30x60; 30x50; 25x50; 25х28; 25x40; 20x60; 20x50; 20x40; 20х35; 20x30 and 15x30.
How to choose the right detail
When performing work with the use of profile pipes with their own hands, the plugs for them are selected based on the scope, material and color. If the profile is to be sealed tightly and the end element will be under pressure, then a simple metal plate is best. It can be welded to a steel pipe with your own hands.
pay attention! Such a decision is categorically unacceptable for PVC pipe.
In the absence of pressure, plastic elements are sufficient, which can be selected regardless of the material of the pipeline. When transporting profile products or the need for short-term use, it is better to use external plastic caps. Their installation and dismantling is very simple.
Internal elements are suitable for long-term operation. After their shrinkage, the integrity of the product is checked. Any cracks in the plastic plugs are not allowed. If, if the cost is important when choosing and there is no need for steel parts, it is better to prefer polyvinyl chloride tips.
Pipe cap is an important and practically necessary element for various pipelines and other areas of use of profile pipes. The variety of types of these elements allows you to choose a part with the necessary aesthetic and operational characteristics.
