., Product introduction
.Double wire, double-sided submerged arc welding spiral steel pipe is a method of arc welding under the flux layer, using welding wire and flux The heat generated by the arc burning under the flux layer melts the wire flux and the base metal.
., Features
.The main features of this product are: first, double-sided submerged arc welding, which not only has a high deposition rate, but also has deep penetration capabilities; second, the arc and welding zone are well protected, and the weld seam It has excellent quality, good density, and the appearance of the weld is flat and smooth, which can meet various performance requirements of the weld.
.. Product implementation standards and uses
.This product implements /, / / standards and is mainly used in common fluid projects such as oil, gas, natural gas, water pipelines, thermal power generation, etc.
., Product specifications
Wall thickness, material grade.
