- EN 10204 3.1 / 3.2 and API 5L certificate
Engineering FAQ
Values are approximate theoretical mass in kilograms per meter (kg/m) for SCH 40 carbon line pipe, useful for freight and coating estimates.
PSL2 includes stricter chemical and testing requirements including impact testing options. Most export projects specify PSL2.
Yes. Coated pipe, insulation and B16.9 fittings can be quoted as a package from the same mill group.
API 5L references consistent NPS, OD and schedule dimensions with ASME B36.10M for ordering and layout.
