Carbon steel round pipe has three actual pairings of6–26 or customized thickness label with6m,6.4m and12m lengths. The thickness option lacks a unit and requires confirmation.

Define a feasible pipe size

Reference OD is220–3000mm and body wall1.2–12mm. Confirm exact OD/wall geometry rather than treating the different ranges as interchangeable actual sizes.

• Carbon Steel Pipe identity.
• Round section.
• ERW technique field.
• Q345B/10#/20#/45# material references.
• Cutting and bending services.

Choose the manufacturing route

Helical-weld and seamless title alternatives are distinct requests. Select the actual route and applicable material standard rather than claiming both for one supplied pipe.

Agree construction acceptance

Request grade, weld and dimensional records. High-strength, boiler and construction contexts do not establish numerical strength, pressure/temperature ratings or certified structural capacity without actual tests.
