API Gate Valve Suppliers in Nigeria

Gate valves are primarily used for positive on/off isolation, rather than continuous throttling. In Nigeria’s oil & gas, refining, gas-transmission and industrial infrastructure, they are selected according to pressure class, nominal size, bore, material and end connection. African Valve is a API gate valve Supplier in Nigeria for pipeline, refining, gas transmission and industrial process applications where reliable isolation and pressure containment are required.

Applications In Nigeria

Gas Transmission: Sectional isolation on major transmission infrastructure such as the OB3 and AKK gas pipeline systems.
Refining: Isolation of hydrocarbon and utility systems at large refinery facilities, including the Dangote Refinery.
Oil & Gas Processing: Crude-oil, natural-gas gathering, transfer and process lines requiring dependable isolation.
Terminals & Storage: Hydrocarbon transfer and storage-piping systems where positive shut-off is required.

Standards

Design and testing are selected according to API 600 or API 6D, with pressure testing to API 598/API 6D and applicable ASME end-connection standards.
