Does the specification require plastic steel composite pipes to be treated as antiseptic?
There are a lot of steel plastic composite pipe can be classified according to the classification, structure of pipe: steel reinforced plastic composite pipe, seamless steel pipe reinforced plastic composite tube, mesh steel plastic composite pipe and steel mesh skeleton plastic composite pipe. At present, the market is the most popular steel reinforced steel plastic composite pipe, steel plastic composite pressure pipe is often said, the middle layer is a layer of steel pipe into high carbon steel by curling forming butt welding, inner and outer layers were high density polyethylene (HDPE).
The plastic lined steel plastic composite pipe does not need anticorrosion.Lining plastic plastic steel composite pipe, a new kind of composite pipe material, is called plastic steel pipe in many places. Steel is an iron material; plastic refers to plastic, plastic steel composite pipe in the plastic is generally high density polyethylene (HDPE).
So excellent performance makes the use of steel plastic composite pipe very extensive, oil, natural gas transportation, industrial and mining pipes, drinking water pipes, drainage pipes, and so on, can be seen in various fields of this kind of pipe.
The middle layer is a steel pipe, so the pipe bearing performance is very good, is different from the aluminum bearing is not high, the largest diameter pipe can only 63mm, the largest diameter of steel pipe can be done 200mm, even more; the middle layer of the steel tube is sealed, so the steel plastic pipe also has the effect of oxygen barrier, can for direct drinking water projects, and the inner layer and the plastic material, has good corrosion resistance.
