Model:Y211
Y211 packer is composed of anti-corrosion barrel in high temperature and pressure, whole central pipe, friction commutator and lower joint. The slip has been treated by carburizing and quenching. The rigidity of surface and toughness of center is very high, so it’s not easy broken when conflicts with load. The barrel is above the slip to avoid covered by sand. The structure is simple and easy to operate.
Characteristics:
a) It’s sealed by pulling and lowering column. It’s released by pulling the column.
b) It is supported by unidirectional slip. Sealing and unsealing are convenient and reliable.
Feature: 1. It can be set in most kind of casing safely and reliably
2. Three seal in two kinds of hardness makes a sealing system.
