Straight seam welded pipe

DataTime:[2016-11-3]
Straight seam welded pipe refers to the production of raw materials for steel in the weld seam welded straight on the device and parallel to the straight seam of the steel pipe. The main raw material is low carbon steel hot rolled coil, hot rolled, in petroleum, metallurgy, construction, mining, port, machinery and other industries widely used in oil and natural gas, low-pressure water gas transportation, mining fluid, conveyor roller, automotive transmission and so on. 

Straight seam welded pipe production process is relatively simple, the main production process is high-frequency straight seam welded steel pipe and submerged arc welding straight seam steel pipe. Longitudinal is hot rolled coil through the molding machine, the deformation of the coil sleek cylindrical shape, the use of high frequency current skin effect and proximity effect or solder layer under the burning arc welding, the tube edge heating and melting, and the effect of the pressing force of a fused, the final cooling molding. Which uses high-frequency currents melting tube edge is called ERW (ERW), is called by arc melting LSAW pipe (LSAW). 

Straight seam steel pipe is mainly used in water engineering, petrochemical industry, chemical industry, power industry, agricultural irrigation, urban construction. For the transport of liquids: water supply and drainage. For gas transportation: gas, steam, liquefied petroleum gas. For structural purposes: as piling pipe for bridges; docks, roads, buildings and other structures pipe.
