Finally emphasis on the importance of surface treatment in the production, strictly control the process parameters when anti rust.
Anti-corrosion steel pipe in the country is mainly used for petroleum, chemical, gas, heat, sewage treatment, water, bridges, steel pipes and other engineering fields.anti-corrosion steel pipe is divided into the following categories.
For the ferritic stainless steels, grain growth in the heat affected zone, welding joint ductility and toughness sharp decline, brittle, easy to form cold cracks in the welding residual stress.
Stainless steel, with its excellent corrosion resistance, abrasion resistance, heat resistance, and its shiny, luxurious surface, and are widely used in various fields of the national economy.
Stainless steel tube is safe and reliable, and health and environmental protection, affordable, thin wall of the pipe, and new reliable, simple and convenient the connection method development success
We know that the stainless steel seamless pipe has a quality demanding for seamless pipe in the environment of high temperature and pressure.
Crevice corrosion is a form of localized corrosion crack in the surface sediments or shielded area surface passivation layer destruction.
In building water distribution system, galvanized steel pipe has been over a hundred years glorious history and a variety of new plastic pipes
For stainless steel seamless pipe, the three elements of the solution treatment temperature, holding time and cooling rate.
ASTM A511/A511M specification covers seamless stainless tubing for use in mechanical applications where corrosion-resistant or high-temperature strength is needed.
