Companies that produce, promise the customer that their products will be a long time without causing complaints and without requiring replacement. Each material has its own advantages and disadvantages that need to know to avoid mistakes in your pipes.
Copper pipes are very common. Their popularity is due to the fact that the metal has high strength and tolerates various types of loads. The only major drawback is their susceptibility to corrosion. Therefore, products have always tried to protect from the interaction with moisture using corrosion-resistant coatings. Until recently, a truly effective way to not exist. Applying different kinds of paints, bitumen did not help solve the problem fully. This coating is very sensitive to mechanical influences, and a scratch on it, formed during the assembly, reduces all the work to protect the surface at no.
There is a reliable way to protect copper products from the negative effects of the environment - hot-dip galvanized. It lies in the fact that the product is immersed in molten zinc. This method allows you to create a coating resistant to mechanical stress, and tight to the copper surface.
PEX tubing does not require this kind. They are practically not affected by rust. The advantage of PEX to copper is in the fact that it is much easier. This means that the design of PEX tubing can be installed without difficulty, without involving heavy equipment. Replacing the damaged segment and does not require much time. The advantage of PEX pipes can be classified as a low cost of equipment for welding.
However, the PEX pipes of this type has its own drawback. They do not have such a strength as copper products, sensitive to various corrosive.
For installation of utilities (PEX plumbing, PEX tubing) is recommended to use pipes made of PEX. During the construction of facilities that are experiencing high loads (main gas and oil pipelines) should be administered pipes, which are used for the manufacture of galvanized copper. This allows products to operate as efficiently as possible.
From PEX manufactures PEX tubing, PEX pipe, insulation for wire and cable, containers (bottles, cans, tanks), galvanic baths, PEX plumbing, fiber, etc., are widely used in various branches of engineering, agriculture and households. The most popular PEX low density. Many technical significance as products of chlorination and chlor sulfirization of PEX.
