PPR elbow has a super long service life, and the better ones can be used for more than 50 years; there are also PPR coupling pipes, such as copper pipes, which are resistant to high temperature and high pressure, and are the best material in water supply pipes. It will be applied to various water supply and drainage projects. Pipes, pipes of different materials have different functions and uses. There are pipes synthesized with chemical components, which are corrosion-resistant, safe and hygienic, light in weight and low in engineering cost.

In the past, some large hotels, especially those above five-star hotels, used sanitary grade 304 stainless steel pipe fittings for all the pipes, which greatly improved the water quality and safety. A better thin-walled stainless steel pipe is characterized by a ratio of wall thickness to outer diameter not greater than 6%. It has high strength, strong corrosion resistance, good toughness, excellent anti-vibration shock and anti-vibration performance, low temperature and no brittleness, safe and sanitary, can ensure the purity of water quality during water delivery, durable and 100% recyclable.
