Section 49-50-10 - Safety valve repair

(a) All national board capacity-certified ASME code section I, "V" stamped safety and safety relief valves and section VIII "UV" safety relief valves, in addition to all other coded piping systems using code-constructed safety and safety relief valves, shall be repaired in accordance with the national board of boiler and pressure vessel inspectors "VR" program specified in NBIC ANSI/NB-23, which is adopted by reference to K.A.R. 49-45-20. Each repair shall be performed by an organization in possession of a "VR" certificate of authorization issued by the national board of boiler and pressure vessel inspectors.

(b) Repair of a safety valve or safety relief valve shall be considered to be the replacement, remachining, or cleaning of any critical part, lapping of the seat and disc, or any other operation that could affect the flow pressure, capacity, function, or pressure-retaining integrity of the valve. Disassembly and either reassembly or adjustments, or both, that affect the safety valve or safety relief valve function shall be considered repairs.

(c) The initial installation, testing, and adjustments of a new safety valve or a safety relief valve on a boiler or pressure vessel shall not be considered a repair if made by the manufacturer or assembler of the valve.

(d) Each valve intended for steam services shall be tested on steam. Each valve intended for air or gas service shall be tested on air or gas. All ASME code section IV "HV" and "V" stamped safety valves and relief valves designed for use on low pressure boilers shall be repaired only by the original manufacturer.
