Electric Fusion Welding (EFW) steel pipe refers to an electron beam welding, the use of the high-speed movement of the electron beam directed impact kinetic energy is converted to heat the workpiece so that the workpiece leaving the melt, the formation of the weld. It is mainly used for welding dissimilar steel welding sheets or which high power density, metal weldment can rapidly heat to high temperatures,
ERW Pipe Manufacturing Process. Electric resistance welded (ERW) pipe is manufactured by cold-forming a sheet of steel into a cylindrical shape. Current is then passed between the two edges of the steel to heat the steel to a point at which the edges are forced together to form a bond without the use of welding filler material.
Erw pipe and electric Welded profiles:buy from Metinvest Application of steel ERW round tubes of small and medium diameter and square and rectangular welded profiles. ERW tubes and profiles are mainly used in the construction and housing-and-municipal sectors. Gas and water steel pipes are mainly used for water and gas piping at residential and industrial buildings.
Steelpipe submerged arc spiral welded (SSAW) steel pipe is ideal for use in structural applications, such as foundation work (pile casing or piling) and in wharf, bridge and building construction projects because it offers major advantages over alternative materials. The spiral forming process produces accurately manufactured pipe that makes the product easy to use and, combined with high-quality welding and

Welded ERW Steel Pipes For Construction. ERW welded steel pipe is a steel pipe made by electric resistance welding after being formed by crimping a steel plate or a steel strip. ERW stands for resistance welding, which has the characteristics of high production efficiency, low cost, material saving and easy automation. ERW welded pipe is one of the most common pipe materials.
