High Quality Welded Tube Pipe Waterproof Price Pipe ERW Spiral Steel Hollow Section Carbon SSAW Metal Galvanized Round Structure
Performance advantages of double-sided submerged arc welding pipe
1, good thermal insulation performance, heat loss is only 25% of the traditional double-sided submerged arc welding pipe, long-term operation can save a lot of energy, significantly reduce energy costs;
2, with strong waterproof and ability, no need to attach a pipe trench, can be directly buried in the ground or water, simple and rapid construction, low comprehensive cost;
3, double-sided submerged arc welding pipe also has impact resistance under low temperature conditions, can be directly buried in the underground frozen soil;
4, can be set up alarm system, automatic detection of double-sided submerged arc welding pipe leakage fault, accurate indication of the fault location and automatic alarm;
5, the service life can reach 30-50 years, the correct installation and use of double-sided submerged arc welding pipe maintenance costs are very low.
