Plastic Pipe is shaped by plastic composite strip spiral wound by welding (lap surface extrusion welding) is made, the inner wall is smooth, corrosion resistant, light weight, easy installation, and other quality characteristics, is environmentally friendly green product, its advantages are: ① long life, life is more than a high-density polyethylene (PE) pipe life of up to five years or more. ② safe and reliable, compared with pure plastic pipe, reinforced steel pipes especially easy to make large-diameter pipe with a safe and reliable enough to ring stiffness. ③ production site, saving transportation costs, steel Pipe can reel (ordinary cable tray) transportation, pipe wrap device is simple and compact, easy to device manufacturers will be transported to the vicinity of the site. ④ flexible or no leakage (electric welding, butt welding) connection, good sealing performance and environmental performance, two sealing connections can be a simple tool manually, without mechanical operation. In addition, steel Pipe stress can also be resolved by the elastic deformation resulting avoid pipe joints due to put too much stress and deformation and leaks or damage, is your best choice in this article is taken from: http: // www. sdzpkmgy.com
