Evaluation will prioritize: capability to meet nuclear facility material standards (ASTM A105/A216 WCB) and ASME B16.5 150# flange specifications. Experience in supplying valves for nuclear or high-hazard chemical processes is likely required. Proven ability to handle corrosive service conditions (e.g., scrubber solutions with KCl, K2CO3, and off-gases with CO2, HCl) may be assessed. Compliance with South African nuclear regulations and NECSA procurement policies is essential.

Scope: Supply of 13 manual valves for the NW Plasma Gas project’s Air Purification System. Deliverables: Ball valves (15, 25, 40mm) and globe valves (40mm) as per the detailed list. Specifications: Valves must meet design conditions (e.g., 38°C operating temp, 1965 kPa(g) pressure) and operating conditions (e.g., ambient temp, 520–550 kPa(g) pressure). Materials: ASTM A105/A216 WCB carbon steel or 316 stainless steel for bodies, RTFE seats, flexible graphite packing. Standards: ASME B16.5 150# flange specifications. Notes: Some valves are shared between NW PlasGas and CWOPG facilities. Process ventilation pipeline sizes may be finalized during HVAC design.
