    Drilling hoses for oil industry

    Drilling hoses for oil industry

    Hoses used to supply cement, clay mud, water, oily emulsions, oil.

    Hoses are efficient in terms:

    • temperate climate at a temperature (-40 to +45) ° C;
    • tropical climate at a temperature no higher than 50 ° C;
    • cold climate at a temperature of not lower than -55 ° C;

    fluid temperature not higher than 80 ° C.

    In terms of reliability the hoses meet to the requirements of GOST 28618-90, GOST 25676-83.

    Guaranteed resource of efficiency - 1000 moto / hours

    End fittings designed for use in the drilling of oil field equipment.

    Perhaps reinforcement with the end fittings for different types of connections on request.

    The hoses with threaded connections R4 may additionally be equipped with adapters upon request BRC Rc4 / Rc4 or adapters Rc4 / flange.
