Short answer. We do not set coating thickness on our own. The owner’s named standard, its edition and the coating class define the required build-up, and the inspection records have to prove it.
- Ask the designer to state the standard, edition and class in the technical agreement before requesting prices.
- Thickness is verified per pipe with a documented procedure, plus holiday detection for dielectric coatings.
- Pipe-end cutback length and the field joint coating build-up are specified separately from the main body coating.
- Request sample thickness and holiday-detection records at the quotation stage so the format is agreed early.
Common references are AWWA C210, C213 and C215 plus ISO 21809; the version stated in the owner’s specification prevails.
On ADB- or World Bank-funded packages the thickness records are usually audited per pipe, so agree the record format and witness points at the quotation stage rather than at the loading port.
See our large-diameter plastic-coated steel pipe for the supply range. Ask us for sample coating thickness and holiday-detection records before you fix the ITP. Send your enquiry.
