What valves are required for EIL vendor approval for Indian refineries?
EIL (Engineers India Limited) maintains a vendor approval list for valves used in IOCL, BPCL, HPCL, and other PSU refineries. Approved vendors must meet EIL's SLMV (Specification for Low-Medium Voltage) and SPC (Specification for Piping Components) requirements. Valves must comply with EIL piping specifications including SPC-044 (Gate Valve), SPC-045 (Globe Valve), SPC-046 (Check Valve), and SPC-047 (Ball Valve). Vajra works with EIL-approved valve manufacturers and can supply valves with EIL inspection.
What is IBR certification and when is it required for refinery valves?
IBR (Indian Boiler Regulations) certification is required under the Indian Boilers Act for valves installed on boilers and steam-generating plant, and for all steam pipelines at pressures above 3.5 kg/cm² (0.35 MPa). For refinery steam service, IBR Form III-C (raw material certificate) and Form III-E (test certificate) must be supplied with the valve. Vajra supplies IBR-certified gate, globe, globe-check, and safety relief valves for refinery steam service.
