FIELD: oil and gas industry.
SUBSTANCE: present invention relates to oil and gas industry, in particular, to a collet-type assembly of a choke module and a Christmas tree in equipment for underwater production of hydrocarbons. Proposed assembly of collet module and X-mas tree accessories comprises first connecting flange, annular hydraulic cylinder, collet, second connecting flange, mandrel made in the form of a ring and made with possibility of axial movement relative to the collet longitudinal axis at axial movement of the piston of the hydraulic cylinder and compression of the collet, respectively, upper connecting flange installed parallel to the second connecting flange and fixed relative to the mandrel; hydraulic cylinder piston is fixed relative to outer edge of upper connecting flange.
EFFECT: technical result is easier dismantling of collet assembly, as well as minimization of accuracy of parts with provision of sealing of connecting bushings.
