Hebei Jinsuo Steel Pipe Manufacturing Co.,Ltd. was established in 1989. It covers 110,000 square meters area with total assets of 250 million and has 400 workers in company including more than 90 technologists and engineers. We can provide the Structure pipe, Fluid pipe, Medium Low-Pressure Boiler pipe,and Petroleum casing pipe and we have 8 sets of advanced SSAW pipe production line, 4 sets of ERW(stretch reduction) pipe production line. The outside diameter of Spiral Double-Side Submerged-Arc Welded steel pipe is from 219mm to 2420mm with wall thickness 5mm-25.4mm. The outside diameter of ERW(stretch reduction) steel pipe is from 89mm to 720mm with wall thickness 4mm-13mm. Our products have been sold to over 28 provinces in China and exported to overseas. ERW (stretch reduction) steel pipe is the national high technology development project of the Ninth Five-year Plan and Torch Plan of China. All pipes are produced mainly according to ASTM A106 Gr.B, ASTM A335,the ASTM A333,the DIN 1629,API SPEC 5L, 5CT, EN10217, GB/T9711.1, GB/T9711.2, SY/T5037, GB/T8163,GB/T8162 Standard. We have a good relationship with the well-known steel pipe factory in China, which help us get the best pipeline with reasonable price.
