What is ASTM A312, ASTM A358, EN 10217-7, JIS G3459 stainless steel welded pipe
ASTM A312, ASTM A358, EN 10217-7, JIS G3459 Stainless steel welded pipe is a type of pipe manufactured by forming stainless steel strips into tubular shape through rolling and then welding them together. It combines the corrosion resistance of stainless steel with the high-efficiency production characteristics of welded pipes, making it widely used in applications requiring rust resistance and durability.
Compared to seamless steel pipes, welded pipes offer lower cost and can be produced in larger diameters, making them a cost-effective choice for many industrial applications.
Specification
Production Process
Material Selection: High-quality stainless steel coils are selected based on the required grade.
Forming: The coils are formed into a cylindrical shape using precision rollers.
Welding: The edges are welded using TIG (Tungsten Inert Gas) or high-frequency welding (HFW) for a seamless finish.
Heat Treatment: Annealing is performed to enhance mechanical properties and corrosion resistance.
Finishing: The pipes are polished, cleaned, and inspected to meet international standards.
