                                                        Pipe ram assembly

Ram assembly consists of ram block, holder, rubber and retracting screw. Top and bottom of rams are symmetric. When top surface of the ram rubber has been worn seriously,another side can be used to prolong rubber life.
For various size drilling tools, only need to change relevant rubber and ram block including blind ram, other element are universal.

Floating performance of the ram is good. Because the ram seat (ram holder) and the ram body (block) are separated, the ram can move slightly in the holder to ensure positive alignment of the rubber faces as face seal contact occurs. There is 3mm installation clearance between the ram body and the ram seat. When shutting off the ram,the holder extrudes top rubber and makes it deform and bulge up to enhance effectiveness of sealing and reduces the wear of the ram packer.
