Installation of caps on profile pipes - final, but an important part of the construction of the fence on the site. This step is necessary to preserve the metal profile pipe. Protected by a cap, the pipe will not be damaged by constant contact with moisture. exept this, Muffler elements can come in handy when building furniture, installation of decorative and functional details in the interior. Installation of such fittings will not be difficult even for those, who does not have significant experience in repair work.
Plugs for pipes are used in a variety of designs, including decorative
Why do you need plugs on the profile pipe?
Caps are small, simple in design, but very important shaped details. They help to insulate the cavity of the profile pipe from getting inside the debris and, the main thing, precipitation. Profile products are used in the construction of fences or wire mesh. If the fence posts remain unprotected, fluid and condensate accumulate very quickly, and due to constant stagnation of moisture metal walls become unusable in a relatively short time. Damaged fence posts cannot guarantee the strength of the whole structure, and profile pipe, isolated cap, becomes just as durable, as well as an integral bar of metal.
In addition to muffling details, parapets and fence caps are also used to protect profile pipes from the negative effects of atmospheric factors. They can have different shapes (even forged nozzles are available) and quite successfully cope with the decorative function.
Pipes, which are part of the street structure, must be muted, so that water does not accumulate in them
Types of caps on the profile pipe
The main point in the classification of these shaped elements - the material, from which the cap was made. The following materials may be used in the production of these parts:
- Different types of metals. Reliable and high-quality fittings, aluminum is most often used for their production, steel or brass. Usually, are equipped with a carving - with their help strong collapsible connections turn out. Due to good strength steel and brass muffler parts have become popular in the field of maintenance of gas pipelines and water mains. Metal plugs are also available for the profile pipe, but they are used only in those cases, if aesthetic and operational properties are very important. Square-section metal plugs are especially in demand in the furniture industry.
- Chrome metal. Expensive fittings are made of this material, which are not subject to corrosion. As in the previous case, the use of muffled elements with chrome-plated steel is relevant only in special conditions.
- Polyethylene and other polymers. Cheaper, but the fittings do a good job. They completely prevent water from entering the pipe, do not spoil from constant interaction with moisture. Plastic plugs can not lose their original shape for a long time: they are not afraid of even temperature fluctuations.
Importantly! At the same time the plastic cap on a profile pipe has to be made of material, well tolerates ultraviolet light. Example, PND (low pressure polyethylene) destroyed by sunlight.
Polymer plugs are the cheapest, but no less effective, than steel
- Rubber. Shaped rubber parts are used only as a temporary plug, designed to protect the pipeline from debris and dust inside. Rubber fittings are not suitable for profile pipes, but they will also be able to find their application at home, example, as a stopper at seasonal closing of irrigation system.
One of the most economical solutions is a homemade cap for profiles. It is a metal plate of the required diameter, welded to the walls of the pipe. Of course, this method should not be used when organizing isolated sections of the water supply or sewerage system.
Design features of plugs for pipes
There are also types of designs of shaped parts for insulation. There are four main types of structures:
- Caps with a thread. On a pipe such details put on by means of the cut carving on a fitting and on a profile.. Shaped details with a carving most often meet metal, but some manufacturers also produce plastic threaded parts. Suitable only for profiles with a round cross section.
- Pneumatic elements. Fixed in the pipe with a pump. When air is pumped into the fitting, it increases in size, and its shape completely coincides with the cavity of the pipe.
- Elliptical details. Such plugs are made only of metal, a welding machine is required for their installation. Their main purpose is permanent fixation on the sewer pipe, but their installation is also possible on support columns of round section.
- Flange elements. Metal or rubber fittings, is established by means of bolts or rivets. Holes are provided for the connection, located along the perimeter of the fitting.
Only end caps are suitable for profile pipes, which are either inserted inside the pipe, or put on top, like a cap
In addition to these varieties, transport plugs are also available, which are designed to preserve the quality of pipes during transportation. Another type of parts - end caps - are made mainly of rubber or flexible plastic for temporary use.
Characteristics of plugs for profile pipes
Technical characteristics of shaped elements depend on a manufacturing material and design features:
- metal - can withstand heat to a temperature of + 500-600 degrees, without changing its structure. Prone to corrosion, which can significantly reduce their service life. To avoid rust on such fittings, they must be covered with a special primer or paint;
- chrome - practical "does not kill" details, but until then, while the layer of a brilliant covering remains intact. At constant mechanical influence on a chromeplated fitting the protective covering is erased, and remains, essentially, simple steel detail, also prone to corrosion;
- plastic - these elements can not boast the ability to withstand the same temperatures, as metal, but in most cases this factor is not required. Plastic plugs for profile pipes have a guaranteed service life 7-10 years, but in the absence of serious negative factors, you can continue to use them much longer.
Caps are also external or internal configuration. For profile pipes plastic fittings of square section are issued only external. And more flexible plugs from polyvinylchloride can be applied and as an internal detail.
Metal plugs can have a more aesthetic appearance, than plastic, but their service life is short due to corrosion
Rules of installation muffle shaped elements
The principle of installation of external caps is very simple. The following rules should be followed for good sealing of plastic plugs for profile pipes:
- If a threaded fitting is installed, a sealing material should be used to improve the strength of this joint. The FUM tape copes best with this function.
- Threaded gaskets are used to seal non-threaded fittings.
- If a metal cap is installed, then in the case of profile pipes it makes sense to make a welded joint. In a situation, when profiles will be reused, and the plug will no longer be needed, it will have to be cut together with a small section of pipe.
No special tools are required to install the plastic fittings - all work can be done manually. If the pipeline from the profile is operated in difficult conditions, then stronger plugs are used. They can be made of metal, some shaped elements are even reinforced.
Installation and removal of caps for profile structures, performing only the supporting function, does not require special safety measures. While muffling gas, water supply and sewerage systems must stop the supply of medium, passing through the pipeline.
Choosing a fitting for fence posts, quite reasonable decision will stop on plugs plastic for a profile pipe. They do well as a defender, and with a decorative function. On sale it is possible to find even monophonic shaped elements with a figured surface: they are spherical, pyramidal, square, and made in the form of a lens. Caps are available in all sizes of profile pipes.
