Structure of gas testing manifold
The inlet of the gas testing manifold is a flange union 3 1/16"-10K * 3"Fig1502F, outlet is a threaded flange 3 1/16"-10K-2 7/8" EUE. The manifold consists of a manual adjustable choke valve, a positive choke valve, Manual Gate valve, Block Tee, Block Cross etc., the manifold will be tested as per standard API 16C.
The valve installed in the manifold is low torque type, and the gas testing manifold is in easy operation that can meet the requirements of oilfield testing requirements.
Manual gate valve is the main part of the gas testing manifold, consist of valve body, valve Bonnet, valve stem and valve seat etc.,
Manual choke valve is the key parts of the manifold, The valve is operated by personnel, Needle assemble and valve seat seals are made by wear resistance special material, the valve featured large body and needle type valve core with large flow, can reduce the shock during chocking, also lower the noise.
Features of gas testing manifold
* The valve is equipped with two heavy duty and loading thrust ball bearings, bearing the loading of open and close valve gate, thus the open torque is very low, easy to operate. The wave spring front seal is adopted between valve gate and valve seat, valve body is full filled with grease, has better sealing performance compared with other types of gate valve.
* The valve gate and valve seat are made by special material that in wear-resisting and corrosion resistance, in long life time.
* The valve bore of the gas testing manifold has very small fluid resistant coefficient that easy for Pipe cleaning.
