In recent years, ERW technology has also been used to produce economical oil access tubes, on the one hand from the low cost of ERW technology; on the other hand, this oil access tube How is electric resistance welded pipe ( ERW ) made?(ERW) Electric resistance welded 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.See all results for this question
How are laser welded tubes different from ERW tubes?
The heat affect zone for laser-welded tubes is much smaller than for ERW tubes. Oxidation and cavitation can also be avoided because the welding is finished in a protective atmosphere. The elongation of the weld line is quite similar with the based material, which is quite suitable for IHPF.See all results for this questionHeat-treating line pipe weld seams - The FabricatorDuring high-frequency welding, the outer and inner sides of the pipe wall experience the highest temperatures. This creates a heat-affected zone (HAZ) with a characteristic hour-glass shape. The heat also changes the tensile properties of the HAZ, reducing its toughness (its ability to absorb an impact without rupturing). Weld-seam heat treatment re-establishes the tensile properties of theHAZ, bringing them back to levels equal to thSee more on thefabricator q345 erw weld steel pipe tubes Heat treatmentHeat Treatment Methods for Carbon and Alloy Steel PipeHeat Treatment Method of Carbon and Alloy Steel Pipe.
