LSAW steel pipe, hot-rolled or cold-rolled steel sheet or steel coil made of steel pipe welding equipment in the straight seam welding are called the straight seam welded pipe. It is cut into strips by a steel strip, and then wrapped into a tubular cold mold. Then a special welder and then a seam welded. Outer weld brightly polished. The inner pipe of the general burr does not hit. Only precision welded pipe can hit the burr. LSAW pipes are used in onshore and offshore oil and gas pipelines requiring critical service, high performance and tight tolerances. It is also applied in conveyance of flammable & nonflammable liquids, and as structural members in construction projects.
