Preventor WITH OVAL DIES PP2-160x21

The preventer allows:
- seal at the wellhead of the tubing with pipe rams of the upper channel of the body;
- seal the wellhead in the absence of tubing with blind rams of the lower channel;
- seal tubing of different diameters at the wellhead, while sealing the wellhead in the absence of tubing is carried out with pipe rams closed on a branch pipe with a ball valve;
- use technological cone inserts complete with a split wellhead gripper (KTO-1) installed on the upper flange of the preventer: split pipe-cable dock shelter GTKR1-180x5; rotary rotating insert GRU1-110x5; centralizer splitter wiper DOR; flushing insert GP1-180x3.5; detachable pipe dock seal GTR1-180x21; detachable cable sealer GKR1-180x5.
