Define a consistent pipe specification and service inspection before agreeing this galvanized supply.

Diameter and wall

The detailed OD scope differs from another 15–50 mm diameter reference. Confirm a compatible actual OD and wall against the 0.3–27 mm thickness option and the separate 2–10 mm wall description.

Length and zinc units

Six and twelve metre lengths are selectable alongside 5.8 without a unit. Clarify that label and the zinc layer written as 0.8–4.0 mm, without silently changing either unit.

Document acceptance

Q235B and several application and certificate references appear. Obtain order-specific documents; API, GB and SABS wording does not establish certification, pressure capacity, corrosion lifetime or approval for an oil or gas installation.
