Changsha Huatao tube stainless steel pipe industry, long-term job security at a temperature of -270 ℃ -400 ℃, whether high or low, will not precipitate harmful substances, materials performance is quite stable; stainless steel pipes tensile strength greater than 530 N / mm , but also has good ductility and toughness. High strength stainless steel pipes, which greatly reduces the likelihood of leaks by external influence, significantly reducing water leakage rate, so that effective protection of water resources and use www.cschgy.com
