A two-step manufacturing route separates forming from final welding.
Weld
Inside and outside spiral seams are submerged arc welded on four welding lines.
Inspect
Welds and pipe bodies undergo inspections and testing to the applicable specification.
Finish & deliver
Coating, end preparation and delivery planning complete the project scope.
Dedicated welding capability.
Four submerged arc welding lines weld the internal and external spiral seams. Digital welding systems and optical seam tracking support the manufacturing process.
Hydrostatic testing, automated ultrasonic inspection and radiography support the requirements of the applicable order. The in-house laboratory performs mechanical and chemical evaluation.

Splicing & double jointing
Discuss joining requirements alongside the required pipe lengths.
Attachments
End plates, conical tips, drive shoes and lifting eyes for specified applications.
Additional finishing
Coal tar epoxy coating and selected minor fabrication, reviewed against the project scope.
Protection suited
to the service.
Coordinate external coating and internal lining with the operating environment, installation method and project specification.
