the company produces API 6A and 16C high-pressure fluid control components for oil fields: swivel elbows, plug, wing-type hammer unions, high-pressure pipes/high-pressure straight pipes (nipples), slab gate valves, choke valves, check valves, safety valves, integral pipe/integral fittings (long radius elbows, right-angle elbows, manifolds, tees, crosses, reducers, flange connections, and plugs), and antiydrogen sulfide series products. High-pressure manifolds assembled from high-pressure fluid control components: annular manifolds, choke manifolds, well manifolds, drilling fluid manifolds, cementing manifolds, wellhead control heads, high and low-pressure combination manifolds, fracturing manolds, and high-pressure surface testing devices. these are widely used in various high-pressure fluid operations and supporting equipment in oil field drilling, cementing, logging,, oil production, acidizing and fracturing, and offshore platforms. Customized special high-pressure combination manifolds can also be designed according to user requirements. The nominal diameter of high-pressure fluid control components is 1" to 4", and the cold working pressure is 14Mpa to 140Mpa (2000Psi to 20000Psi).
