AF type wellhead fittings

The fittings are designed for wellhead sealing, well pipelines suspension, control and monitoring of working medium flow from the well (during production of product by flowing or mechanised method) or into the well (for operation in the mode of fluid injection from the RPM system); control of well and injected medium parameters in the pipe, annulus, intertube space; performance of necessary technological operations during well operation, including at overpressure of medium in the well or injection well.
