what is ssaw steel pipe?
Spiral welded pipe ( SSAW pipe , also called HSAW pipe ). The pipe is formed by spiral submerged arc welding technology. Spiral welded pipes are formed using narrower plates or hot rolled coils , which lowers their production costs significantly. The welding line shape like a helix. The spiral welding process permits the production of large-diameter pipes suitable for transporting large volumes of oil and gas. Some SSAW pipes are historically limited to low pressure 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
test: chemical component analysis, mechanical properties(ultimate tensile strength, yield strength, elongation), technical properties(flattening test, bending test, blow test, impact test), exterior size inspection, hydrostatic test, pneumatic test, ultrasonic testing (ut), x-ray test.
mill test certificate: en 10204/3. 1b
third party inspection: sgs,bv, etc.
surface: lightly oiled, hot dip galvanized, electro galvanised, black, bare, varnish coating/antirust oil, protective coatings(coal tar epoxy; fusion bond epoxy, 3-layers pe)
