Pneumatic-Hydraulic Safety Clamps Type MP
Description
Reasonably combined pneumatics and hydraulics, the operation of the pneumatic-hydraulic safety clamps type MP is simple, and the installation of the hydraulic control slip is easy and convenient. The fastening and loosening of the pipe can be completed through the operation of the hydraulic cylinder. Requiring no manual handling, the operation with circulating pressure can be realized. Manufactured according to API Spec 7K standard, this pneumatic-hydraulic safety clamp is mainly applied for making up or breaking out pipes during well drilling in oil and gas field. This product can effectively prevent the pipes without shoulder or coupling from falling off.
