In April 2017, Roc-Master received the PPL Tender No.SMP/FP/301/2016 for supply of Duplex and CRA Lined/Clad Line Pipes Well Nasr X-1 Feeder Line at Gambat South which is a thin-wall pipe weld overlay project.  Under the circumstances of non-related project experience, through repeated experiments, process adjustment and equipment improvement by the technical and equipment department, Roc-Master successfully weld overlaid the thin-wall pipe of 6mm*6000 mm(L), which is not only highly recognized by customers, but also being appreciated for its strong team work ability. Roc-Master has acquired more thin-wall weld overlay experience, which lays a better foundation for future similar projects.
