Standard for SSAW steel pipe

SSAW (Spiral Submerged Arc Welding) steel pipes are widely used in various industries due to their flexibility and cost-effectiveness in handling large diameters. These pipes are manufactured by spirally welding strips of steel, resulting in a pipe with a spiral seam.

Key Standards for SSAW Steel Pipes

- International Standards

API 5L: Specification for Line Pipe

The American Petroleum Institute (API) standard for pipes used in conveying gas, water, and oil in the oil and natural gas industries.

Grades include A25, A, B, X42, X46, X52, X56, X60, X65, X70, and X80.

ASTM A252: Standard Specification for Welded and Seamless Steel Pipe Piles

Used for piling purposes in construction projects.

ASTM A139/A139M: Standard Specification for Electric-Fusion (Arc)-Welded Steel Pipe (NPS 4 and Over)

Used for various pressure applications.

ISO 3183: Petroleum and natural gas industries - Steel pipe for pipeline transportation systems

International Organization for Standardization (ISO) standard for pipeline transportation systems in the petroleum and natural gas industries.

Similar to API 5L.

- Regional Standards

GB/T 9711: Steel pipe for pipeline transportation systems

Chinese national standard similar to API 5L, covering SSAW pipes used in the oil and gas industry.

EN 10217-1/2: Welded steel tubes for pressure purposes

European standard for welded steel tubes used in pressure applications, including SSAW pipes.

BS 4360: Specification for weldable structural steels

British standard for structural steel, including welded pipes.

Conclusion

SSAW steel pipes are governed by a range of international and regional standards ensuring quality and suitability for various industrial applications. Understanding these standards helps in selecting the right type of SSAW pipe for specific needs, ensuring safety, reliability, and efficiency in their application.
