Spiral seam double-sided submerged arc welded steel pipe, referred to as double-sided submerged arc spiral welded pipe, is a type of steel pipe produced by a specific process.
Raw material treatment: the strip steel is sent to the welded pipe unit, and the strip steel is gradually rolled up by multiple rollers to form a circular tube blank with an opening gap.
Forming and welding: The raw material strip steel is spirally formed by a forming machine, and the internal and external submerged arc welding technology is used to continuously weld the narrow band (plate) coil to form a steel pipe. In this process, adjust the pressing amount of the squeezing roller, so that the weld gap is controlled at 1~3mm, and the two ends of the weld are flush.The production process is simple: the production process of double-sided submerged arc spiral welded steel pipe is relatively simple, the operating cost is low, and it has the advantage of low-cost operation.
Wide range of applications: medium and large-diameter low-pressure water pipes, thermal pipes and piling pipes have price advantages in the market, and are widely used in oil and gas long-distance pipeline projects, urban water supply, drainage, sewage and other fields.
Strong pressure bearing capacity: double-sided submerged arc spiral welded pipe can withstand a certain pressure, suitable for pressure fluid transportation.
