Spiral Tube
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.

Features of Spiral Tube
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-user requirements.
Main usage: oil and natural gas transportation pipeline project、Refining Pipeline project、urban water supply and drainage project.
