Product Description
The submerged arc welded steel pipe is a spiral seam steel pipe made of strip steel coil as raw material, often warmly extruded, and then welded by an automatic double-wire double-sided submerged arc welding process. The characteristics of submerged arc welded steel pipe: the production process of straight seam welded pipe is simple, the production efficiency is high, the cost is low, and the development is relatively fast. The strength of the spiral welded pipe is generally higher than that of the straight seam welded pipe.
Compared with the same length of straight seam pipe, the length of the weld is increased by 30~100%, and the production speed is lower. Therefore, the smaller diameter welded pipes are mostly straight seam welded, and the large diameter welded pipes are mostly spiral welded.

Insulation and anti-corrosion double-sided submerged arc welded pipe refers to the steel pipe in different working environments to ensure the internal temperature and surface temperature of the working double-sided submerged arc welded pipe at the same time to slow down or prevent the chemical and electrochemical action of the external medium or by the metabolic activity of microorganisms. Corrosion and deterioration of thermal insulation and anti-corrosion measures.
Performance advantages of double-sided submerged arc welded pipe for thermal insulation and anti-corrosion:
[1] The thermal insulation performance is good, and the heat loss is only 25% of the traditional double-sided submerged arc welded pipe. Long-term operation can save a lot of energy and significantly reduce energy costs.
[2] It has strong waterproof and corrosion resistance, no need for additional pipe trenches, and can be directly buried in the ground or water. The construction is simple and fast, and the overall cost is low.
[3] The double-sided submerged arc welded pipe also has good corrosion resistance and impact resistance under low temperature conditions, and can be directly buried in the underground frozen soil.
[4] The service life can reach 30-50 years, and the correct installation and use can make the maintenance cost of the double-sided submerged arc welded pipe extremely low.
[5] An alarm system can be set up to automatically detect leakage faults of double-sided submerged arc welded pipes, accurately indicate the fault location and automatically alarm.
