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
