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.
