On the base of the petroleum,natural gas transmitting pipeline and the pipe using of China, the article introduced the production and application of the spiral welded pipe both home and abroad, the development of the LSAW(Longitudinal Submerged Arc Welded) pipe abroad, oil and gas transmitting linepipe domestic demand. Compared the performance property of the Longitudinal submerged arc welded pipe and spiral welded pipe. Pointed out that LSAW developed rapidly and spiral welded pipe fade away day by day due to many reasons. The article also analyzed the supply and demand of LSAW pipe according to the plan and programming for oil and gas pipeline constructing and introduced actual status of petroleum pipeline production and the development of LSAW in China.
