EN 10217 Application of SSAW Pipe
1.Oil and gas industry
Long distance pipelines for oil and gas that can withstand high pressure and corrosive environments.
2.Chemical industry
Suitable for conveying corrosive chemicals pipeline system.
3.Building and structural engineering
can be used for building structural support, piling engineering, etc.
4.Water transport and hydraulic engineering
Piping systems used to transport water, both seawater and fresh water.
5.Power industry
Piping systems for power plants, especially in high temperature environments.
6.Marine engineering
Due to its corrosion resistance and high strength, SSAW steel pipes are also suitable for offshore platforms and submarine pipelines.
Characteristics of EN 10217 SSAW Pipe
1.High strength and pressure resistance
SSAW steel pipe adopts double-sided submerged arc welding process, which has high weld strength and can withstand high pressure.
2.Good corrosion resistance
By strictly controlling the chemical composition of raw materials, such as the content of carbon, sulfur, phosphorus, etc., SSAW steel pipes have good corrosion resistance.
3.Large diameter and thick wall
The outer diameter range of SSAW steel pipes is usually 219.1 mm to 2032 mm, and the wall thickness can reach 6 mm to 25.4 mm, which is suitable for the engineering needs of large caliber and thick wall.
4.High production efficiency
The spiral winding production mode makes the production efficiency of SSAW steel pipe high, and can quickly meet the needs of large-scale projects.
5.Strong adaptability
Steel pipes of different diameters and lengths can be produced according to different engineering needs.
