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.
