A new composite pipe, a lot of places referred to as the steel plastic pipe. Steel, is a kind of iron materials; plastic, refers to the plastic, steel plastic composite pipe in plastic is generally high density polyethylene (HDPE). Steel plastic composite pipe has many kinds of classification, according to structure classification pipe for: steel reinforced steel plastic composite pipe, seamless steel tube reinforced steel plastic composite pipe, mesh steel plastic composite pipe and steel mesh skeleton plastic composite pipe. At present, the market is the most popular is the steel reinforced steel plastic composite pipe, steel plastic composite pipe structure that we Steel plastic composite pressure usually said the pipe, this pipe steel belt layer and the middle layer is a high carbon steel by curling forming butt welding, the inner and outer layers are of high density polyethylene (HDPE). The middle layer is a steel pipe, so the pipe pressure bearing performance is very good, unlike the aluminum strip, pressure is not high, the largest diameter only 63mm pipe, steel plastic tube maximum aperture can do 200mm, even more; because the steel tube of the middle layer is sealed, so this kind of steel pipe also has the function of oxygen barrier. Can be directly used for direct drinking water project, and its inner and outer layer is the plastic material, has the very good corrosion resistance. So good performance, making use of steel plastic composite pipe is very extensive, petroleum and natural gas transportation.
