What this certificate means

Repairing or altering a code-stamped vessel is not the same as building a new one. The R stamp, issued by the National Board, authorises us to carry out repairs and alterations to ASME-stamped equipment under the National Board Inspection Code, so the unit keeps its code status after the work. It is especially relevant when you send us a heat exchanger for retubing, re-rating or modification.

What it covers

Repairs to ASME-stamped heat exchangers and pressure vessels
Alterations and re-rating under the NBIC
Retubing and tubesheet repairs
R-stamped nameplate and NBIC repair / alteration reports (R-1 / R-2)

Why it matters for buyers in the Gulf

Refineries, gas plants and utilities across the UAE, Saudi Arabia, Qatar, Oman and Kuwait routinely require ASME stamped and National Board registered equipment in their specifications. Having these authorisations in-house means you get code-stamped equipment straight from the manufacturer, with the data reports your inspectors expect.

Questions about our certificates

Can I verify your certificates independently?

Yes. ASME and National Board authorisations can be checked on their public directories, and ISO certificates can be verified with the certification body named on the certificate. We are happy to give you the certificate numbers for this.

Which unit will build my order?

It depends on the size, type and code requirements of the equipment. We will tell you in the quotation which unit will build it and which certificates apply.
