Q235B galvanized round pipe has three actual pairings of0.2–20mm wall range with6m,6.4m and12m lengths. Exact OD/wall must be selected against the actual pipe drawing.
Distinguish actual and family sizes
Body references include OD3–700mm, diameter15–50mm and wall2–10mm. They do not replace the actual wall label or establish every combination as available.
- Round Pipe Tube shape.
- Slightly oiled description.
- Cold-drawn/hot-rolled alternatives.
- Q235B grade field.
- Cutting and bending services.
Clarify zinc measurement
Zinc-layer0.8–4.0mm retains original units. Request actual coating measurement basis instead of converting or asserting a verified thickness.
Agree standards and service
API/GB/SABS/JIS/GS names require actual evidence. Oil/water/boiler contexts do not establish pressure ratings, installation approval or corrosion life without selected-pipe tests.
