The main difference between the plastic pipe and stainless steel pipe

 First, the plastic pipe usually use ordinary galvanized welded steel pipe, pipe, seamless # 20, by preheating make various polyethylene powder PE, epoxy plastic powder, roller or spray method made. Strength plastic pipe Existing pipe, another plastic pipe corrosion, wear resistance, fluid resistance small advantages, is a new water supply, pipeline corrosion. It overcomes the galvanized pipe rust easily, resulting in yellow water, produces a small plot masonry pipe diameter, clogging and other defects, to prevent secondary pollution, improve water quality have significant effects, the market share also increased year by year.301 harden stainless steel strip
In addition, the use of plastic pipe according to different powder, suitable for -30 ℃ ~ 95 ℃ working environment, coating with high adhesion, coating its high hardness, good impact resistance, good chemical resistance corrosion, can be widely used in building water supply and drainage water supply enterprises, residential district in hot and cold water transport and industrial water recycling, fire sprinkler, HVAC, gas, petroleum, chemical corrosion, external corrosion of buried cables and external corrosion, desulfurization various fluid corrosion, UV resistant corrosion, corrosion and other fire-retardant anti-static conveyor.Low alloy structural steel welding rod
Second, more use of the stainless steel pipe market walled tubes, beautiful appearance, good hygienic properties, corrosion resistance, smooth wall, small weight characteristics. But also has its drawbacks, the wall is very thin, prone to cause mouth when construction elliptical water connections, as well as when there are external compression prone to scratches depression is not easy to repair, easy installation construction, more expensive than steel pipe much higher.ASTM A53 Galvanized Carbon steel pipe
