When IBR stamping is required

Piping under the Indian Boiler Regulations — main steam, feedwater, blowdown and related boiler mountings — needs valves with IBR approval and Form III-C. Ordinary API 600 WCB gates without IBR are not accepted on those lines.

Frequently asked questions

What is Form III-C?

The IBR certificate for valves and mountings, signed by the manufacturer and countersigned by the Inspecting Authority.

Are all WCB gates IBR?

No. IBR must be specified on the order so the valve is manufactured and certified under IBR.

Lead time for IBR gates?

Typically longer than commercial WCB due to inspection scheduling — confirm on RFQ.
