| Company Introduction: | glass In Hebei the letter steel pipe Limited company produces steel pipe's specialized factory, the total area 100,000 square meters, the existing staff 160 people, have 2 home advanced spiral seam two-sided submerged-arc welding steel pipe production line, 3 hot rolling steel pipe production lines, 2 expand the tube production line. Its leading product is: ¦Ő219mm-¦µ2420mm, wall thickness 6mm-20mm spiral seam two-sided submerged-arc welding steel pipe; ¦Ő16mm-¦µ630mm, wall thickness 2mm-30mm hot rolling steel pipe. The product sells to national 28 provinces, the city, the autonomous region, and exports countries and the area and so on Southeast Asia and Middle East. The product carries out API SPEC 5L, 5CT, GB/T9711.2, SY/T5037, GB/T8163, the GB/T8162 standard. The spiral steel pipe uses now the advanced production equipment and American Lincoln completely buys the arc welding machine automatically, and provided the online digit ultrasonic flaw detector, the static hydraulic pressure testing machine, the X-ray real-time to become the camera and so on complete quality testing instrument examination, the company product passes through ˇ°China oil industry special-purpose tubing quality surveillance test centerˇ± the examination, attained a designated standard completely. Our company production operation spiral steel pipe (spiral seam weld steel pipe, spiral welded pipe, the Cangzhou spiral steel pipe, coil, screw winding steel pipe), the seamless steel pipe (seamless tube), the straight seam steel pipe (straight seam welded pipe), expands the steel pipe, the hot rolling steel pipe, the heavy-caliber heterogeneous steel pipe (heavy-caliber steel pipe), the galvanization steel pipe (galvanized pipe), the welded steel pipe, the pressure steel pipe, the anticorrosion steel pipe, the heat preservation steel pipe, the flange, the bend, to be greatly curved hotly, the Three Contacts and so on. |
