Material for the manufacture of plugs for the profile pipe
The plugs perform a number of important and useful functions. We list them.
- Protect the profile structure from moisture, and therefore make the construction more resistant to corrosion.
- Close the pipe so that no garbage gets into it.
- Prevent ingress of various insects, such as wasps, bees and other dangerous ones.
- Used in furniture and perform a protective function. Prevent damage to the floor covering( installed on the legs of sofas, chairs, bedside tables, etc.).
- Gives the original appearance of the product.
The plugs are of different shapes, suitable for the pipe profile. Do not forget that their sizes are different, which means that a 30x30 millimeter cap, designed for a square tube, does not fit for a smaller or larger section.
Depending on the fixation, this product is classified into: flanged, wafer, flat weld, spherical, rotary and elliptical.
Although the variety of stubs is not that big, but the material you will definitely be able to pick up. It almost always corresponds to the profile pipe. Thus, metal products are made using stainless steel( well, or ordinary steel), aluminum or other non-ferrous metals. As a rule, the installation of the plug is not difficult. However, sometimes you have to use welding. For example, an ordinary iron plate can serve as a stub. It is adjusted to the size of the profile pipe and welded.
As for plastic plugs, polymers are used for their manufacture. The most popular is considered polyethylene. It is more resistant to mechanical influences, nevertheless its strength wants to be better( if compared with metallic analogs).
The purpose of the plastic plug is to create a high-quality and reliable sealing of the end face of the communication. In addition, they are able to hide some fastening elements on the profile pipe, its defects, and also serve as a conventional decorative element.
Plugs made of plastic are divided into two groups: external and internal.
Outer: a common element that is worn over a profile pipe.
Advantages: It creates a sealing of the pipe, protects its end, and also the nearby area( up to 5 centimeters).
Disadvantages: Low strength, and also, it is easy to remove.
Internal: completely inserted into the profile pipe, leaving only the decorative part.
Advantages: The stiffeners increase the strength of the case and simplify installation.
Disadvantages: The cost is more expensive than the outdoor ones.
Special types of plugs
Before you go for the purchase of the plug, you need to consider the conditions of its use. If temperature changes or an aggressive environment are anticipated, it is best to use metal products. After wandering around the shops, you will probably find special, double stubs. They are reinforced, manufactured using different alloys and can withstand temperatures, up to 600 degrees Celsius. However, for a moist environment, it is best to use plastic plugs for profile pipes. As mentioned above, they are resistant to corrosion, which means your product will be protected. In extreme cases, the market offers additional polymeric materials that are able to contact different chemical compounds.
Specialized plugs are used for: pipelines( can function at high pressure), aggressive environment using gasoline, oil and various chemical elements.
