Wellhead Equipment for Installation of the Oil Well Pump

AShK50x14K1(K2)-7(8,9)

TU 3665-009-49652808-2004

Base variant 

It is intended for wellhead sealing, controlling of its operational mode, installation of devices to perform well research and technological operations.

The body has side outlets to install angle valves. There is an adapter with channels to install polished rod packing and to connect tubing. There is a release valve that allows to relieve extra gas pressure from the annular space to the channel with the product.

Flange of the body has mounting and sealing surfaces to install technological equipment.

Unlike other analogs, AShK50×14 has minor weight and size characteristics, large variety of technological possibilities with minimal number of check and control valves.

It can go in set with the polished rod stuffing box SUpk-2-73 that has a blowout valve and a spherical ball joint that allow to compensate angle misalignment of the well head and the pumping unit during movement of the ground.

Check valve KZ1-50×14 provides safe flow cut-off due to the usage of the combined sealing element.

Climatic category of the wellhead equipment — UHL(HL1) in accordance with the national standard GOST 15150-69.

Temperature ranges +40°C −60°C.

Depending on the Customer’s order any variant and combination are possible.
