904L stainless steel welded pipe

Advanced Manufacturing Process of Stainless Steel Welded Pipe

Our stainless steel welded pipe production begins with high-quality slabs or billets cast in specialized steel mills. We employ three primary manufacturing methods:

• Electric Resistance Welding (ERW)
• Fusion Welding (EFW)
• Double Submerged Arc Welding (DSAW)

During the manufacturing process, plates are precisely formed through hot or cold rolling before welding. To ensure premium quality, our 904L stainless steel welded pipe undergoes thorough surface finishing, including careful scarfing to remove weld flash from both outside (O.D.) and inside (I.D.) surfaces. Heat treatment further enhances the weld zone's uniformity.

Properties of 904L Stainless Steel Welded Pipe

904L stainless steel welded pipe offers exceptional characteristics that make it ideal for demanding applications:

• Superior resistance to strong reducing acids, particularly sulphuric acid
• Enhanced copper content for improved corrosion resistance
• Excellent resistance to stress corrosion cracking
• Outstanding crevice corrosion resistance
• Non-magnetic properties
• Superior formability and toughness
• Exceptional weldability
• Low carbon content for optimal performance

Advantages and Applications

Our stainless steel welded pipe, particularly in grade 904L, provides several benefits:

• Tighter dimensional tolerances compared to seamless pipes
• Cost-effective solution for large-scale projects
• Versatile applications in engineering and construction
• Available in various diameters and wall thicknesses
• Ideal for high-pressure and corrosive environments
• Perfect for chemical processing and marine applications

As a leading manufacturer, stockholder, and supplier of 904L stainless steel welded pipe, we ensure all products meet ASTM A312 specifications while providing competitive pricing and reliable delivery schedules.
