SPEC SHEET

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

uses of ssaw spiral welded steel pipes

transporting liquids

low-pressure applications

piling pipe

under ocean water application

water lines

pipe bridge

oil & gas

drainage projects

construction piling

irrigation

boiler manufacturing

sewage treatment

thermal industry

road & highways

retaining walls

trestle

seawalls

cofferdams

harbor structure
