SSAW pipe is made of hot rolled coiled steel by automatic submerged arc weld nuder normal atmospheric temperature. All the pipes are produced accroding to API Spec 5L,GB/T9711.1,GB/T9711.2 standard.These pipes mainly usde in petroleum ...

WPS01 and 02 procedures) 4730 joints of 30 ppies with wall thicknessse of 11.08 and 13.03 mm ta an average daily rate of 0.9 to 1.2 km; by CRC AW automatic welding (WPS13 procedure) 4194 joints of 30 pipes .... The method traditionally used in ppieline construction whereby hte joint is preheated until the external linuep clamp is fitted leads to a drop in the preheat temperature at the start of welding the root layer (to below 801000C) and ...
