Specifications stainless steel pipes and tubes

we specialize in stainless steel welded pipes/tubes, normally used for decoration and industry

Stainless steel pipes & tubes are widely used for many areas as follows: 1. decoration, door, windows, handrail, ladder, furniture and so on. 2. heat-exchanger, condenser, boiler pipeline parts and superheater. 3. pressure pipelines, petroleum transmission pipes, petrolchemical industry pipes, liquid delivery pipe, water pipelines. 4. milk transmission, sugar factory, dairy, sanitation, bathroom pipes and other sanitary areas. 5. other industry pipes which need the corrosion-resistance and pressure material. 6. any other pipelines. We have many kinds of stainless steel pipes & tubes, including 201, 202, 301, 304, 316L, 2205 and so on As regards to the product standard, we produce the stainless steel pipes & tubes in strict accordance with ASTM A249, A269, A270, A312, A554, DIN 11850 and so on. Being a professional manufacturer of welded stainless steel pipes and tubes, we can supply many kinds of welded stainless steel pipes and tubes over 12000 tons per year. All of the stainless steel pipes and tubes we product include AISI 201, 202, 301, 304 and 316L which are pickling and widely used in many area, just like pharmacy, food industry, petroleum industry, heat exchange and decoration. We manufacture the welded stainless steel tubes and pipes meeting the ASTM A249/A269, A270, A312, A554 and DIN 11850 requirements. We are always improving our technique about welded stainless steel tubes and pipes production. We also accept OEM orders and production. ASTM A554 is a Standard Specification for Welded Stainless Steel Mechanical Pipes/Tubes. ASTM A554 standard covers welded stainless steel pipes/tube for mechanical applications where appearance, mechanical properties, or corrosion resistance is needed, and as-welded or cold-reduced mechanical stainless steel pipes/tubes in sizes to 16 in. (406.4 mm) outside dimension, and in wall thicknesses 0.020 in. (0.51 mm) and over.   1) Material of stainless steel:
