With the exploration and innovation of company people, gradually formed four major advantageous products: steel plate, steel pipe, stainless steel, special steel.

    Types of Oil & Gas Pipes: Seamless, ERW, LSAW longitudinal seam steel pipe

    The two main types of LSAW pipes are the longitudinal (with a single or double straight seam weld, DSAW) and the spiral type (called, HSAW, SSAW or SAWL pipe). Therefore, the difference between DSAW vs. LSAW is that DSAW pipes have a seam weld in the inside and outside of the pipe, whereas LSAW pipes have a single seam weld on the outer surface.Difference between helical welded pipes and longitudinal longitudinal seam steel pipeAs the name shows, longitudinal pipe has a straight welding seam on the pipe surface. Different from the longitudinal pipe, the welding seam of which is vertical to the axial line of the pipe, helical welded pipe is rolled and welded according to certain helical angles.Longitudinal Seam Welded Pipe, Longitudinal Seam Welded longitudinal seam steel pipeAbout 26% of these are steel pipes, 1% are stainless steel pipes. A wide variety of longitudinal seam welded pipe options are available to you, such as 10#, a53(a,b), and q235. You can also choose from astm, api, and jis. As well as from ul, ce, and bsi. And whether longitudinal seam welded pipe is fluid pipe, structure pipe, or hydraulic pipe.
