Product Description

Customized Large Diameter Stainless Steel Welded Pipe 304/316L ASTM A312 for Industrial Use

 

1. Product Description 

Stainless steel welded pipe is a tubular product manufactured by cold-forming stainless steel coil or strip into a tubular shape and then longitudinally welding the seam using continuous high-frequency or tungsten inert gas (TIG) welding. The weld zone is typically subjected to solution annealing or post-weld heat treatment to restore corrosion resistance and mechanical properties. Depending on the application, the pipe can be produced as cold-rolled or hot-rolled, with either single-weld or spiral-weld configurations. Common material grades include austenitic (304/304L, 316/316L), ferritic (409, 430), martensitic (410), and duplex (2205, 2507) stainless steels. The product conforms to international standards such as ASTM, EN, JIS, and GB, ensuring high quality and traceability.

2. Product Applications 

 

Sector Typical Uses
Oil, Gas & Chemical Process piping, refinery lines, offshore platforms
Water & Environment Desalination, sewage treatment, potable water networks
Food, Beverage & Pharma Sanitary lines, sterile processing, CIP/SIP systems
Architecture & Structure Facade supports, handrails, bridges, decorative screens
Energy & Heavy Machinery Heat exchangers, condensers, exhausts, hydraulic systems

 

3. Product Advantages 

🔗 Zero-Compromise Weld Zone
Advanced welding with inert gas shielding + post-weld heat treatment eliminates sensitization, making the weld as strong and corrosion-resistant as the parent metal.

✨ Mirror-Like Surface Quality
From matte 2B to mirror-polished #8 finish, our surfaces reduce fouling, simplify sterilization, and deliver premium aesthetics for exposed architectural projects.

📐 Precision Fit, Every Time
State-of-the-art straightening and sizing mills guarantee exceptional straightness and tight OD tolerances, enabling quick, trouble-free on-site installation.

♻️ Sustainable & Circular
100% recyclable, with a service life exceeding 50 years in most environments—a responsible choice for green building certifications.
