HYDRAULIC CENTRALIZER

Model

Torrent-CW-HC

The casing hydraulic centering device is designed to improve the centering of casing and the cementing quality to overcome the short comings of common centralizer at present in order to meet the requirement of layered production and high pressure separating layer fracturing.

‍

Feature

It can be connected in any location of casing strings, it is moderate length and can be connected conveniently in the wellsite.
It has self-protection device to makes sure to run smoothly in the hole and does not occur expansion advance. It has a locking mechanism, the expansion will not retract.
It is controled through hydraulic and have strong support force.
It has higher grade material to ensure the strength of the casing string.
It has larger range of deformation, meet the hole diameter enlarging rate of 30% .
It has combined sealing for hydraulic cylinder sealing to guarantee the sealing effect.
The heat-resisting material is used so that the working temperature is as high as180℃.
The annular flow area is not affected after expansion.
