Common Questions
What does LSAW stand for?
LSAW stands for Longitudinal Submerged Arc Welded — steel pipe produced by forming plate into a cylinder and welding the longitudinal seam with double-sided submerged arc welding. SAWL (Submerged Arc Welded Longitudinal) is the same product under API 5L annex naming.
What is the difference between LSAW and SSAW pipe?
LSAW pipes have a straight longitudinal seam from steel plate; SSAW (HSAW) pipes have a spiral seam from steel coil. LSAW offers higher pressure ratings and better dimensional accuracy. SSAW provides wider OD range and lower cost per meter.
What is the difference between LSAW and ERW pipe?
LSAW uses submerged arc welding with filler wire for large-diameter pipe (16"–60" OD). ERW uses electric resistance welding without filler wire, suitable for smaller diameters up to approximately 20" OD. In the overlap zone (16"–20"), selection depends on pressure class and wall thickness.
What is the difference between LSAW and DSAW pipe?
DSAW (Double Submerged Arc Welded) specifically refers to pipe with both inner and outer submerged arc weld passes. Virtually all modern LSAW pipe uses double-sided welding, so LSAW and DSAW are functionally equivalent.
What sizes of LSAW pipe are available?
Standard LSAW pipe sizes range from OD 406 mm (16") to 1,500 mm (60"), wall thickness 6–75 mm, and lengths 3–18 meters. Custom dimensions available based on project requirements.
What is the HS code for LSAW pipe?
The primary HS code for LSAW pipe is 7305.11 — longitudinally welded steel pipes with an outer diameter exceeding 406.4 mm. The exact tariff classification may vary by destination country.
How much does LSAW pipe cost?
Pricing is project-specific — grade, OD, wall thickness, quantity, coating, and destination all affect cost. MetalFromTurkey benchmarks across partner mills for competitive pricing. Request a quote for current pricing.
Do you provide Mill Test Certificates?
Yes. Every LSAW pipe order ships with EN 10204 3.1 MTCs, hydrostatic test reports, dimensional inspection certificates, and NDT reports (UT and radiographic examination).
What is the minimum order quantity?
MOQ depends on grade, size, and coating requirements. Contact our sourcing team with your specification for exact MOQ and lead time information.
Can you supply PSL2 sour service LSAW pipe?
Yes. PSL2 with Annex H supplementary requirements for sour service (H₂S) can be coordinated through our partner mill network.
