Product Introduction
.Double-wire, double-sided submerged arc welding spiral steel pipe is a method of arc welding under the flux layer. The heat generated by the arc burning between the welding wire and the flux under the flux layer is used to melt the welding wire and flux. Formed from parent 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.
.Spiral tube is a commonly used material in spiral tubes. It is a spiral seam steel pipe that is made of strip steel coils as raw materials, extruded at regular temperatures, and welded by automatic double-wire double-sided submerged arc welding technology.
./ is made of hot-rolled steel strip coils as pipe rings, often heated and spirally formed, and made by double-sided automatic submerged arc welding or single-sided welding. It is used for general low-pressure liquid transportation such as water, gas, air, and steam. Use submerged arc welded steel pipe. / is the petroleum ministry standard, generally called the ministry standard. Spiral seam submerged arc welded steel pipe for general low-pressure fluid transportation () is a submerged arc welded steel pipe made by double-sided automatic submerged arc welding or single-sided welding for general low-pressure fluid transportation such as water, gas, air, and steam.
