Main Products
    1. API 5L SSAW Steel PipeThe raw materials of the same width can be processed in different forming angles to manufacture SSAW steel pipes in various diameters.
    1. EN 10217-2 ERW Steel PipeOur EN 10217-2 standard ERW steel pipes are either alloy steel pipes or non-alloy steel pipes. With circular sections, they meet the testing requirements of both TR1 and TR2. This range of welded steel tube is ideal for pressure equipment used at high temperature conditions.
    1. EN10219-1 Straight Seam Steel PipeOur EN10219-1 standard straight seam steel pipes are cold formed pipes with circular, square or rectangular cross sections. The special manufacturing technique for the ERW steel pipe eliminates the demand for heat treatment after pipe forming.
    1. Line PipesWe can offer two categories of line pipes: SSAW steel pipe and black steel pipe. By changing the forming angle, our range of API 5L line pipes can be made into various diameters while using raw materials of the same width.
    1. Galvanized Steel PipeThe galvanized pipe is a great solution to transfer low pressure liquid, gas, etc. Contact us now if you are looking for galvanized steel tube for delivering water, sewage, fuel gas, air, heating steam, etc.
    1. ASTM A252 Longitudinal Welded PipeOur longitudinal welded pipe is produced in accordance with the ASTM A252 Standard Specification for Welded and Seamless Steel Pipe Piles. During the manufacturing process for this range of ERW steel pipe, heat treatment, non-destructive test and hydrostatic test are not required.
