paip lancar

A seamless steel pipe is a circular pipe having a hollow section and no seams around it.  The seamless steel pipe is made of carbon steel, alloy steel, stainless steel ingot or solid tube blank, and then is made by hot rolling, cold rolling or cold drawing.  Seamless pipes are considered superior to welded pipes as they are built using monolithic steel billets, with intrinsic mechanical strength, without seam welds.

Welded pipes used for oil and gas transmissions, it includes the pipes manufactured in seamless and welded (ERW, SAW). Materials covers API 5L Grade B, X42, X46, X52, X56, X60, X65, X70, X80 PSL1 & PSL2 onshore, offshore and sour services.

Paip lancar ialah paip bulat yang mempunyai bahagian berongga dan tiada jahitan di sekelilingnya. Paip lancar diperbuat daripada keluli karbon, keluli aloi, jongkong keluli tahan karat atau tiub pepejal kosong, dan kemudian dibuat dengan rolling panas, rolling sejuk atau lukisan sejuk. Paip lancar dianggap lebih baik daripada paip dikimpal kerana ia dibina menggunakan bilet keluli monolitik, dengan kekuatan mekanikal intrinsik, tanpa kimpalan jahitan.
