Elite Piping Manufacture Co., Ltd

Welded steel pipe (steel pipe manufactured with a weld) is a tubular product made out of flat plates, known as skelp, that are formed, bent and prepared for welding.

Electric Resistance Welded, often abbreviated as ERW, is a process that uses specific machinery to shape the pipe and tubing. A continuous steel sheet is unwound from a coil and shaped using contoured rollers, forcing the edges together under pressure. These edges are then welded together by heating the material to over 2,000 degrees. After welding, the pipe or tubing is cut into the exact size needed.

SAW is normally operated in the automatic or mechanized mode, however, semi-automatic (hand-held) SAW guns with pressurized or gravity flux feed delivery are available.

SAW pipe is made of hot rolled coiled steel by automatic submerged arc weld under normal
atmospheric temperature. All the pipes are produced according to API Spec 5L, GB/T9711.1, GB/T9711.2, ASTM A252-89 standard. These pipes mainly used in petroleum and natural gas industry to transport flammable and non-flammable liquid and steel construction.

SAW means submerged arc weld ,it can be classified into LSAW and SSAW

API 5L Welded

API 5L Welded refers to the welded steel line pipes that are used for the transportation of oil, gas, water, and other fluids. These pipes are manufactured according to the American Petroleum Institute (API) 5L specification, which sets standards for the materials, manufacturing processes, and testing procedures of the pipes.

API 5L Welded pipes are made by forming a flat steel strip into a cylindrical shape and welding the edges together using either a continuous or a spiral welding process. They are available in various grades of steel such as X42, X52, X60, X65, and X70, with higher grades indicating stronger steel.

Application: Oil, Gas and water delivery; Refinery, Boiler and Mechanical equipment manufacturer; structure construction; drilling, ship building and etc.
