Spiral Welded Pipe GB/T9711 L245M OD1422MMX15.8MM Cement Mortar Lining

Product Detail

SSAW SPIRAL WELDED PIPES

SSAW spiral welded pipe is made of hot rolled coiled steel by automatic submerged arc weld under normal atmospheric temperature. All the pipes are produced according to API Spec 5L standard and other standard. These pipes are mainly used in petroleum and natural gas industry to transport flammable and non-flammable liquid and steel construction
