Preventers with manual drive PPSHR, PPS, 1PPS, PP, etc.

Small-sized spot preventers with manual drive are used during routine and major well repairs, all types of geophysical work, including perforation and drilling and blasting, as well as when cutting side boreholes. They have an all-cast alloy steel body without a single joint, including welded, which eliminates the need for flaw detection during technical inspections.
Features:

• heating of the spot cavities with steam through the internal chambers preserves the operability of the preventers at temperatures up to -50 ° C;
• lifting hooks, solidly cast with the body, allow you to use any kind of slinging when installing the preventer;
• the simplicity of the design of the preventers ensures the reliability of their closure at low pressure in the hydraulic system, as well as a small torque and a small number of turns of the steering wheels when closing the dies manually;
• polymer seals used in the design of preventers have increased wear resistance and rigidity, work better in conditions of negative temperatures, which ensures uninterrupted operation of preventers in the harshest conditions;
• simple repair technology and the minimum required set of spare parts allow maintenance of preventers in the field and ensure operability during the designated service life of 5 years, with the possibility of extension up to 8 years.

Special features:

• The use of technological inserts from the composition of 1KG. To do this, the preventers, in the designation of which there is a "T", have a conical passage and side screw stops (sliders) installed in the upper flange to fix the inserts in the housing.
• The holes on the lower flange, made in the form of ellipses, make it possible to attach to various types of mouth fittings.

They have certificates of conformity, permits for use, patents of the Russian Federation, positive customer reviews.
