Performance advantages of submerged arc welded steel pipe

Submerged arc welding steel pipe is a strip coil as raw material, often warm extrusion molding, spiral with automatic double wire submerged arc welding process double-sided welded pipe joints.

Characteristics of submerged arc welded steel pipe

ERW production has the advantages of simple process, high production efficiency, low cost, rapid development. Spiral welded pipe ERW pipe strength than high, with a narrow billet production of large diameter pipe, can also use the same width of the billet production of different pipe diameters. But with the same length of straight pipe, weld length of 30~100%, and the production rate is low. Therefore, most of the small caliber pipe welded, large diameter welded pipe mostly using spiral welding

Performance advantages

Anti-corrosion insulation double submerged arc welded steel pipe refers to the pipe in different work environment to ensure the work of double submerged arc welded pipe inner and surface temperature at the same time to reduce or prevent the chemical, electrochemical effect medium or by microbial metabolism and erosion and deterioration of the insulation and anti-corrosion measures.

Performance advantages of heat preservation and corrosion protection and double side submerged arc welded steel pipe:

1. Heat insulation performance is good, the heat loss is only 25% of the traditional double side submerged arc welded pipe, long-term operation can save a lot of energy, significantly reduce the cost of energy.

2. Has a strong waterproof and corrosion resistance, without a trench, can be directly buried underground or in water, the construction is simple and rapid, low comprehensive cost.

3. Double side submerged arc welded pipe also has good corrosion resistance and impact resistance at low temperature, which can be directly buried in the ground.

4. Service life of up to 30-50 years, the correct installation and use of double-sided submerged arc welded pipe repair costs are extremely low.


5. Can set the alarm system, automatic detection of the double side submerged arc welded pipe leakage fault, accurate indication of the fault location and automatic alarm.
