Carbon seamless pipe has one actual12m/0.5–27mm wall-range pair. St37.0,SCH160 and15/30inch title requirements need exact size and material confirmation.

Define actual geometry

Family OD3–700mm, diameter15–50mm and wall2–10mm are independent. Confirm selected OD/wall rather than assuming every title size fits the ranges.

• Round pipe shape.
• Cold-drawn/hot-rolled references.
• Q235/Q345/St-family materials.
• Customized dimensions described.
• ±1% tolerance reference.

Clarify surface and standards

Zinc-layer0.8–4.0mm is retained as original field, requiring relevance and measurement-basis confirmation. JIS/GS names are not verified approval.

Request service evidence

Wardrobe/fluid/boiler contexts do not establish pressure ratings or certified suitability. Request actual material, process, schedule and dimensional tests before use. Clarify whether the zinc field applies to the actual supplied surface.
