SSAW Steel Pipe

SSAW/SAW STEEL PIPES

What is SSAW Steel Pipe?

SSAW steel pipe is made up of hot-rolled coiled steel using a double-sided submerged arc welding method. The welding process allows the steel pipes manufacturers to produce large-diameter steel pipes suitable for different applications.

What Are The Advantages of SSAW Pipes

SSAW steel pipe can be produced in longer length (maximum length up to 50 meters) compared to LSAW steel pipes

Due to its spiral seam SSAW pipe has an accurate diameter accuracy and strength

The sizes are adjustable & can be tailored to end-users requirement

Usage: Used for low pressure liquid delivery, such as water, gas, and oil.
