Usage
Generally used in welding into pipelines for fluid transportation, metal structures, pile foundations, etc.
The products are widely used in water supply projects, petrochemical industry, chemical industry, electric power industry, agricultural irrigation, and urban construction. They are one of the twenty key products developed in our country. Used for water supply and drainage for liquid transportation. For gas transportation, coal gas, steam, and liquefied petroleum gas are used. It is used as piling pipes for structures, pipes for bridges, wharves, roads, building structures, etc.
Features
It can use narrower billets to produce welded pipes with larger diameters, and can also use billets of the same width to produce welded pipes with different diameters. The production cost is low, the process is simple
and it is easy to produce large-diameter pipes. Large-diameter welded pipes mostly use spiral seam submerged arc welding process.
Raw materials
,
., Product introduction
.Double wire, double-sided submerged arc welding spiral steel pipe is a method of arc welding under the flux layer, using the combination of welding wire and flux It is formed by the heat generated by the arc burning under the flux layer, melting 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.
