Preventers with the manual drive

Small-sized plashechny preventers with the manual drive are used when carrying out routine maintenance and overhaul repairs of wells, all types of geophysical works, including punched and prostrelochno-explosive works, and also at kickoff of lateral trunks of wells. Have tselnolity the case from the alloyed steel without uniform connection, including welded that exempts from need of carrying out defectoscopy at engineering certifications. Heating of plashechny cavities the ferry via internal cameras keeps operability of preventers at temperatures up to -50 °C. Lifting hooks, wholly cast with the case, allow to use any kinds of a strapping at installation of the preventer. Simplicity of a design of preventers provides a small torque and small quantity of turns of steering wheels of management when closing dies manually. The polymeric consolidations which are used in a design of preventers have the increased wear resistance and rigidity, work in the conditions of negative temperatures better that ensures trouble-free operation of preventers in the most severe conditions. The simple technology of repair and the minimum necessary set of spare parts allow to carry out service of preventers in field conditions and provide working capacity during all service life.
Special opportunities:
Use of technological inserts from structure 1KGOM.
For this purpose at preventers in which designation there is "T" cone-shaped pass and a lateral screw emphasis (rams) installed in the top flange for fixing of inserts in the case is executed.
The openings on the lower flange executed in the form of ellipses give the chance of accession to various types of fittings of the mouth.
There are certificates of conformity and permissions to application.
