Applications of Stainless Steel 304 Welded Pipes
Frequently Asked Questions
Stainless Steel 304 Welded Pipe is manufactured by rolling stainless steel plates or coils into a cylindrical shape and welding the seam. It offers excellent corrosion resistance, high strength, good weldability and is widely used in industrial, commercial and structural applications.
SS 304 Welded Pipes are commonly manufactured according to ASTM A312, ASTM A358, ASTM A778, ASME SA312, ANSI B36.19M and ASME B36.10M standards to ensure consistent quality and dimensional accuracy.
These pipes provide excellent corrosion resistance, superior weldability, good mechanical strength, easy fabrication, attractive surface finish, low maintenance and long service life while remaining cost-effective.
Welded pipes are produced by welding stainless steel strip or plate, making them more economical and readily available in larger sizes. Seamless pipes are manufactured without a welded joint and are generally preferred for high-pressure and critical applications.
SS 304 Welded Pipes are available from 1/8" NB to 24" NB with schedules including SCH 5S, SCH 10S, SCH 40S, SCH 80S, SCH 160, XS and XXS. Custom sizes and cut lengths are also available.
These pipes are extensively used in chemical processing, food and beverage plants, pharmaceuticals, dairy industries, water treatment facilities, oil & gas, petrochemicals, heat exchangers, construction and architectural applications.
Quality tests typically include Hydrostatic Testing, PMI (Positive Material Identification), Radiography, Eddy Current Testing, Flattening Test, Flaring Test, Dimensional Inspection and Visual Examination.
