Carbon Steel API 5L ERW vs Seamless Pipe

API 5L ERW API 5L Seamless

Manufacturing

Cold-rolled strip, HF-welded seam construction.

Wall & Cost

Lighter wall thickness at a lower cost per meter.

Lead Time

Fast lead time available on ready stock sizes.

Best Fit

Ideal for low to medium pressure pipeline duty.

Manufacturing

No weld seam extruded directly from solid billet.

Strength

Higher load-bearing capacity across all wall grades.

Duty Rating

Preferred for high-pressure, high-temperature service.

Cost & Time

Higher cost with longer mill production lead time.

API 5L DSAW Pipe FAQ

What is the minimum order for API 5L Welded Pipe?

MOQ depends on size and weld type; smaller ERW diameters allow lower tonnage.

Can ERW and LSAW pipe be mixed in one shipment?

Yes, mixed weld-type or mixed-size loading is possible as long as every bundle is heat-tagged for traceability.

Do you support NACE MR0175 sour service orders?

Yes, PSL2 chemistry, CVN testing and full NACE documentation are available on request.

What is the typical delivery time to the GCC?

Ex-stock ERW and LSAW sizes typically reach Gulf ports in 15–20 days by sea.
