Everything You Need to Know About SSAW Pipes: A Complete Guide

Spiral Submerged Arc Welding (SSAW) pipes are gaining traction in various industries, owing to their unique manufacturing process and exceptional properties. This comprehensive guide explores everything you need to know about SSAW pipes, along with vital statistics and data to help you make informed decisions.

What are SSAW Pipes?

SSAW pipes are made from steel coils that are spirally welded into a tubular shape. This manufacturing method allows the production of large-diameter pipes, often used in transporting oil, gas, and water. The spiral welding ensures a stronger bond and superior structural integrity.

Key Manufacturing Processes

The main process involved in the production of SSAW pipes includes:

• Steel Coil Preparation: Hot or cold-rolled steel coils are processed.
• Forming: The coils are formed into a spiral shape.
• Welding: The edges are submerged and welded using arc welding techniques.
• Testing: Assured quality through various tests such as hydrostatic and non-destructive testing.

SSAW Pipe Specifications

SSAW pipes are classified by their nominal diameter and wall thickness. According to API 5L and ASTM standards, the varieties include:

• Outside Diameter: Ranges from 219 mm to 3000 mm.
• Wall Thickness: Ranges from 5 mm to 25 mm.
• Grades: Ranges include LSAW, SSAW according to ASTM A252, API 5L, etc.
