High-Precision ERW & SSAW Welded Pipes from China Factory - Leading Suppliers of Quality Tubes
Product Introduction
Our workshop is a large-scale production unit, producing and marketing high precision, high-strength ERW welded pipe, spiral welded pipe, roller tube, solar stand tube, sporting goods tube, high-precision structure tube, piling pipe etc.
Lies in Jinghai district, Tianjin, a very convenient traffic place. It is 190kms away from Beijing Capital International Airport, 56kms from Tianjin Binhai International Airport, 80kms from Tianjin Port. Many highways also well connected, The perfect geographical position attracts many customers. That covers 300,000m² area, with the total investment over 600 million RMB. Currently there are 500 staffs including 50 senior engineers.
Now pocketed four advanced ERW steel pipe production lines, four spiral steel pipe production lines, two 3PE anti-corrosive production lines, one production line of outer coating with plastic and inner coating with epoxy, and one insulation steel pipe production line. Annual output of SSAW steel pipe (Ф219mm-Ф3000mm, W.T: 5mm-30mm) is 100 thousand tons; The annual output of ERW (Ф33.4mm-Ф273mm, W.T: 3mm-14mm) is 300 thousand tons; The steel grade can be Q235B, Q345B, GR.B, H40, J55, K55, X42, X52, X70, X80, N80, P235, P265, S235, S275, S355. Annual output of anti-corrosive steel pipe (Ф50mm-Ф2540mm) is 3 million square meters, and insulated steel pipe is 500 thousand square meters.
