Wellhead device and gas tree

product description

KR thermal recovery wellhead equipment is composed of X-mass tree and tubing head. Tubing spool bottom is connected with bottom flange and the upper part of tubing spool joints X-mass tree.

The valve of (KR) thermal recovery wellhead assembly is provided with the parallel gate prevailing throughout the world presently. The valve body、bonnet、gate and stem are all fabricated form heat-resisting materials with good creep properties. Therefore, the valve can resist 380℃ and its opening and closure are easy without deformation under high temperature and pressure，What’s more, no-metal sealing elements are fabricated from heat-reinstating materials, which can ensure the good sealing characteristics under the 380℃.
