Savoy Piping Inc. supplies API 5L welded line pipe — LSAW, DSAW and HSAW (submerged-arc) — for large-diameter oil and gas transmission systems.

Related: API 5L Seamless, PSL1 Welded Hub, PSL2 Welded Hub, ISO 3183 Welded SAW.

What is API 5L SAW / LSAW pipe?

Longitudinal or helical submerged-arc welded line pipe is the usual route for larger OD transmission lines. Order by grade, PSL, weld process, OD/wall, coating and NDE package.

Also see: API 5L seamless line pipe hub · Carbon seamless hub · CS buttweld.

Typical applications

  • Large-diameter oil and gas trunk lines
  • Onshore transmission packages preferring LSAW or spiral SAW
  • Coated line pipe (3LPE / epoxy) for buried service

Seamless vs welded

Choose seamless for many smaller OD packages; choose LSAW/DSAW/HSAW when diameter and project specs call for welded line pipe.

Frequently asked questions — API 5L Welded LSAW Line Pipe

What is API 5L LSAW / SAW welded line pipe?

API 5L welded line pipe made by LSAW, DSAW or HSAW (submerged-arc processes) is used for large-diameter oil and gas pipeline transportation where welded product form is specified.

When to use SAW instead of seamless?

Use seamless for many smaller OD packages. Use LSAW/DSAW/HSAW for larger diameters where plate-formed welded pipe is the project standard.

Which welded grades are available?

Typical supply covers Grade B through X70 in PSL1/PSL2 as LSAW, DSAW or HSAW, with coating and sour-service options when required.

PSL1 vs PSL2 for welded line pipe?

Same rule as seamless: PSL2 adds toughness, tighter chemistry and more documentation. Match the PSL on the purchase order.
