The fittings are designed for sealing oil wellheads, regulating their operation mode, installing ESPs, connecting devices for examining wells and performing technological operations.
At the request of the customer, it can be completed with a lubricator.
The valves are equipped with reliable, easy-to-operate and highly hermetic valves ZD 65-210M.
The lack of free volume in valves of this type excludes the possibility of water ingress into the internal cavities and freezing. The alloys and materials used provide high wear and corrosion resistance.
The climatic version of the wellhead fittings is UHL1 (HL1) in accordance with GOST 15150-69.
The limiting values of the operating temperatures of the ambient air are from +40 to -60 ° С.
