Product Description
LSAW pipe is a kind of steel pipe with weld seam parallel to the longitudinal direction of the steel pipe, mostly made of hot-rolled or cold-rolled steel plate or steel strip coil on welding equipment for straight seam welding. According to the different uses, LSAW pipe can be roughly categorized into several types such as scaffolding pipe, fluid pipe, wire casing, bracket pipe, guardrail pipe and so on.
Its high production efficiency and low cost, so it is widely used in various industries. For example, ordinary carbon steel wire casing is a kind of straight-seam steel pipe, which is used to protect electric wires in electrical installation works such as industrial and civil buildings and installation of machinery and equipment. In addition, due to its low cost and high production efficiency, LSAW pipe is also used in a large number of applications for the transportation of fluids, gases or solids, such as low-pressure water pipes, water supply and drainage pipes, heating pipes, low-pressure process pipes, low-pressure fire-fighting pipes and so on.
In addition, there are some special types of LSAW pipes, such as L245 LSAW pipes and transformer cooling oil LSAW pipes, etc. Most of these welded pipes are made of higher materials, such as Q235A grade steel, 16Mn, 20#, etc., to meet specific industrial needs.
LSAW pipes have become an indispensable part of many industries due to their diverse applications and efficient production processes.
