Packer

Casing packer Casing packer High pressure-resistance, good-sealing, good -tightness, stable, secure. API and ISO

Application and classification:

Packer Y221 can be widely used for zonal injection, extraction, leak finding, squeeze, acid treatment and well texting.

According to the structure is divided into: Y221 Packer and Y221M Packer means including hydraulic anchor

According to whether including the wash over function is divided into:  F means including the well-flushing function 

According to the Max OD is divided into: Y221-80,Y221-95,Y221-110,Y221-112 and

Y 221-114

Feature:

1, High pressure-resistance, good-sealing, good -tightness, stable, secure.

2, Setting securely, operate simply and unsealing

3, Setting and unsealing repeatedly

Keeping the above mentioned characteristics of the company, we also carry out the following improvement:

1. Hydraulic anchor use stainless steel materials, which effectively prevent the phenomenon hydraulic anchor claw rust and not back happened because of long time, poor water quality in the sealing process.

2. Glue tube material are made of import modified hydrogenated butadiene acrylonitrile rubber vulcanization, which has the characteristics: high temperature resistance, anti-aging, resistance to high pressure difference. Once uncured after a long time in seal compression, the recovery is good.

3, Anchor claw and slip are set with hard alloy, which increased the bite of casing ability; it is suitable for different styles.

4. Slip and slip bowl are combined with wedge, which makes set or unsealing easy.

5. Center tube is designed with internal the sand controls scream so that it is easy to be recovery.

6 Sealing slip has been made surface carburized quenching with 20 watts Cr M n Ti, so that tube is easy to get stuck and hard to break down.

The design of packer is scientific; Production processing technology is controlled strictly,   good performance characteristics.
