Common Questions
What is the difference between SSAW and LSAW?
SSAW/HSAW has a spiral seam and supports very large diameters. LSAW has a longitudinal seam and is commonly used for thicker-wall, high-pressure applications at lower maximum diameters.
What helix angle is typically used for HSAW pipe?
Typical helix angle is selected by mill design and project target, commonly in the 45° to 80° range. Angle selection affects weld orientation and stress distribution, so project tolerances are confirmed in the technical offer.
How are ovality and helical seam tolerances controlled?
Ovality and seam offset tolerances are controlled to the applicable API 5L/project tolerance package and verified during dimensional inspection before release.
What is the maximum diameter you can supply?
Partner mills can supply up to 2540 mm (100 in.) outside diameter depending on project schedule and grade.
Can you supply PSL2 sour service requirements?
Yes, PSL2 with NACE-related supplementary requirements can be coordinated for suitable project scopes.
Which coatings are available?
3LPE, 3LPP, FBE, CML and bitumen options are available based on service environment. For 3LPP, continuous service is typically up to 110 °C with short-term peak capability to 140 °C.
Do you provide water-pipe standards like AWWA C200 or EN 10224?
Yes. For municipal and utility projects, offers can be aligned with AWWA C200 and EN 10224 requirements, with NSF/ANSI 61 scope included when specified for potable-water contact.
Can you support preliminary working pressure checks?
Yes. Preliminary wall-thickness screening can be shared using Barlow-based calculations, then finalized against the governing project code and design factors.
