Description
Présentation du produit
LeTuyau soudé en acier inoxydable est un appareil performant, corrosion-resistant pipe manufactured from premium austenitic stainless steel grades (304, 304L, 316, 316L, 301L, 314, et 200/400 série) through advanced ERW (Soudage par résistance électrique) technologie. Produced in strict accordance with international standards including ASTM A269 (general service tubing), ASTMA312 (high-temperature and corrosive service pipe), and ASTM A213 (boiler and heat-exchanger tubes), this welded pipe delivers exceptional corrosion resistance, mechanical strength, and long service life in demanding industrial environments. Available in a wide range of outer diameters from 8mm to 101.6mm (0.31″ to 4″) with wall thicknesses ranging from 0.3mm to 2.0mm, and in standard lengths of 5.8m, 6m, or custom, this pipe is suitable for a broad spectrum of applications including petrochemical, traitement chimique, boiler systems, transformation des aliments, and construction. The welded construction offers a cost-effective alternative to seamless pipe while maintaining excellent pressure integrity and corrosion resistance. With multiple surface finishes (pickling, annealing, mechanical polishing, hand polishing) and ISO certification, this pipe is the trusted choice for engineers and procurement professionals worldwide.

FAQ
T1: What are the differences between ASTM A269, A312, and A213?
UN: ASTM A269 covers seamless and welded austenitic stainless steel tubing for general corrosion-resistant and low/high-temperature service, suitable for general industrial piping. ASTM A312 covers seamless, welded, and heavily cold-worked austenitic stainless steel pipe for high-temperature and general corrosive service, suitable for petrochemical and high-temperature applications. ASTM A213 covers seamless ferritic and austenitic alloy-steel boiler, superheater, and heat-exchanger tubes. The choice depends on your application requirements.
T2: What is the difference between SS304 and SS316 stainless steel?
UN: SS316 contains molybdenum (2–3%), offering superior resistance to pitting and crevice corrosion in chloride environments compared to SS304; it is suitable for seawater and chemical applications. SS304 is suitable for general corrosive applications and is more cost-effective. SS304L and SS316L are low-carbon versions that offer better resistance to intergranular corrosion after welding.
T3: What is the difference between welded and seamless steel pipes?
UN: Welded steel pipes are made by rolling steel strips into a tubular shape and welding the seam (using the ERW process); they offer lower costs and high dimensional accuracy, making them suitable for general industrial and corrosive applications. Seamless steel pipes have no weld seams and are suitable for high-pressure and high-temperature applications, though they are more expensive. For most general industrial applications, welded steel pipes are a cost-effective choice.
T4: What surface finish options are available for welded stainless steel pipes?
UN: A variety of surface finishes are available, including pickled, annealed, hand-polished, mechanically polished, BA, 2B, Non. 1, Non. 4, 8K, and HL. Pickled and annealed finishes are suitable for general industrial applications, while polished and BA finishes are suitable for decorative and sanitary applications.
Q5: Can welded stainless steel pipes be customized for length?
UN: Oui. Standard lengths are 5.8m, 6m, and 12m, but custom lengths can also be produced according to customer requirements.
