Confirm compatible pipe dimensions before defining fabrication and coating acceptance.

OD and wall scope

The description gives a broad OD range and another 15–50 mm reference. The actual wall option spans 0.5–27 mm, differing from the separate 2–10 mm description, so agree one physically compatible actual size.

Material and length

Q235B is listed with other steel references and a 12 m actual length choice. Select the supplied designation, manufacturing route and end preparation with material and dimensional evidence.

• Actual material designation
• Compatible OD and wall
• Confirmed 12m supply
• Zinc layer measurement basis
• Fabrication and inspection scope

Coating acceptance

The zinc layer is written as 0.8–4.0 mm. Clarify its intended meaning without silently changing the unit; application and certificate names do not establish pressure performance, corrosion lifetime or compliance for every material and dimensional combination.
