SSAW pipe is spiral submerged arc welded pipe made with a helical weld seam. It is widely used for large diameter piling pipe, water transmission pipe, structural pipe and infrastructure projects.

Which standards are common for spiral welded pipe?

Common references include ASTM A252 for pipe piles, ASTM A139 for straight or helical electric-fusion arc-welded pipe, API 5L and ISO 3183 for line pipe, and EN 10219 for structural applications.

Q: What should be confirmed for pipe pile orders?

Confirm grade, outside diameter, wall thickness, pile length, end condition, straightness, welding inspection, driving requirements, coating or bare surface, marking and bundle or loose loading plan.

Q: Can SSAW pipe be coated or lined?

Yes. SSAW pipe can be supplied bare, black, painted, FBE, 3LPE, 3LPP, internal epoxy or cement mortar lined when coating thickness, cutback, holiday test and handling requirements are confirmed.

Typical Applications

Where SSAW pipe is specified

Pipe piles and foundationsPort piles, bridge foundations, marine works, temporary works and infrastructure foundations where large OD and project length are required.

Water and utility pipelinesWater transmission, drainage, slurry, irrigation, utility lines and municipal pipeline packages requiring coating, lining and pressure test records.

Structural and civil projectsStructural columns, supports, casing, culvert pipe and civil works where diameter, wall, length and delivery schedule drive procurement.

Piling note

For pipe piles, confirm grade, OD, wall, length, driving condition, end preparation, straightness, weld inspection and whether shoes, caps or special marking are needed.

Coating note

For water or utility projects, coating and lining must be settled early: FBE, 3LPE, 3LPP, internal epoxy, cement mortar lining, cutback and holiday test.

Buyer FAQ

Questions to settle before quotation

What is SSAW pipe?

SSAW pipe is spiral submerged arc welded pipe with a helical weld seam. It is often selected for large diameter pipe piles, water transmission pipe and infrastructure projects.

Which standards are common?

Common references include ASTM A252 for pipe piles, ASTM A139 for straight or helical arc-welded pipe, API 5L and ISO 3183 for line pipe, and EN 10219 for structural use.

What should be confirmed for pipe pile orders?

Confirm grade, OD, wall, pile length, end condition, straightness, weld inspection, driving requirements, coating or bare surface, marking and loading plan.

Can SSAW pipe be coated or lined?

Yes. It can be supplied bare, black, painted, FBE, 3LPE, 3LPP, internal epoxy or cement mortar lined when coating thickness, cutback and holiday test are confirmed.
