Helical Seam Longitudinal Spiral Submerged Arc Welded Steel Pipes EN10025

EN 10025 Submerged Arc Welded Steel Pipe Waterproof Corrosion Resistance

Submerged arc welded steel pipe: It is a spiral seam steel pipe made of strip steel coil as raw material, often warmly extruded, and welded by 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.

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. Good thermal insulation performance, 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 to automatically detect leakage faults of double-sided submerged arc welded pipes, accurately indicate the fault location and automatically alarm.

The standard for steel pipe pile mostly is EN 10025 or ASTM A252. Grades in three levels, Gr 1, Gr 2, and Gr 3. OD ranges from 250 mm (10 inch) to 1500 mm (60 inch), thickness normally from 8 mm to 25 mm.

Famous offer a range of different profiles to suit your demands and these steel pipe piles can be supplied in various diameters, wall thicknesses and lengths in accordance with ASTM standards.

Application:

Steel pipe pile is a most recommend piling material for sea port constructions, yard buildings. It has been widely used in sea works or marine works, to create the tough foundations. Other than this, typical uses also as under buildings, bridges, and structural constructions. More details uses as below list:

Onshore and offshore constructions
Marine foundations / constructions
Tower building
Railway, highway construction
Dock yard construction
Sea works, marine works
Oil and gas filed fundations
Structural support in special buildings
and etcs.
