API 6A Production Choke
Positive or adjustable choke for wellhead and production control
API 6A production choke supplied from qualified manufacturers for wellhead, manifold and test-separator duty. Positive (bean / orifice) chokes set a fixed flow; adjustable needle-and-seat chokes let the operator change rate without changing out a bean. Trim is selected for erosion, H2S and produced solids. Documentation follows API 6A at the manufacturing plant.
Products are supplied to the stated API / ISO / ASME / AWWA standards from qualified manufacturers for projects in Saudi Arabia, including Dammam, Jubail, Yanbu, Riyadh, Jeddah and the Eastern Province.
