Specification
SSAW steel pipe
Production process: Spiral-seamed welded steel pipes are manufactured using the submerged arc welding (SSAW) method. This method ensures high weld strength, even load distribution, and resistance to internal and external pressure. The pipes are suitable for use in the oil and gas industry, construction, and pile foundations.
Application area: Used for transporting low-pressure liquids such as water, gas, and oil. Also used in construction projects and for installing pile foundations.
Standards: API 5L, API 5CT, ASTM A252, ASTM 53, EN10217, EN10219, BS 5950, ASTM A572, JIS, IS;
Certificate: EN10217, EN10219, API 5L PSL1 / PSL2, API 5CT
Outer diameter: 219.1 mm – 3048 mm
Wall thickness: 5.0mm-30mm
Length: Up to 70 m
Steel grade:
API 5L: GR A, GR B, X42,X46, X56, X60,X65,X70
ASTM A252 GR 1, GR 2, GR 3
ASTM A53: GR A, GR B, GR C, GR D
BS 4360: Grade 43, Grade 50
