Oil & gas line pipe

01 / DESIGN INPUTS

Service conditions define the sourcing route.

Design pressure, temperature, transported medium, location class, installation method and operating philosophy can introduce toughness, hardness, chemistry, weldability and dimensional requirements beyond the basic grade.

02 / SPECIAL REQUIREMENTS

Make supplementary testing visible at enquiry stage.

Sour service, low temperature, offshore duty or strain-based design may require HIC, SSC, CVN, DWTT, hardness mapping or manufacturing procedure qualification. These requirements materially affect mill eligibility and lead time.

03 / PROJECT CONTROL

Preserve identity through coating and transport.

Pipe numbers and heat traceability are reconciled with test records, coating reports, tally sheets and shipment documents. Handling and storage procedures protect bevels, coating and identification.
