Anti-corrosion surface treatment process of spiral pipe
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.
Stainless steel welding technical requirements and quality assurance measures
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 carbon steel composite pipe
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 flexible multiple tube
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
Stainless steel seamless pipe crack detection method
We know that the stainless steel seamless pipe has a quality demanding for seamless pipe in the environment of high temperature and pressure.

Stainless steel seamless pipe cracks principle and protective measures
Crevice corrosion is a form of localized corrosion crack in the surface sediments or shielded area surface passivation layer destruction.

Usage characteristics of thin-walled galvanized stainless steel tube
In building water distribution system, galvanized steel pipe has been over a hundred years glorious history and a variety of new plastic pipes
Stainless steel seamless pipe solution treatment effect
For stainless steel seamless pipe, the three elements of the solution treatment temperature, holding time and cooling rate.

ASTM A511/A511M Standard Specification for Mechanical
ASTM A511/A511M specification covers seamless stainless tubing for use in mechanical applications where corrosion-resistant or high-temperature strength is needed.
