Covered Slip Hydraulic Liner Hanger


For India and Iran Only

This unique compact design [shortest length ever in the world] liner hanger could be installed in highly deviated or horizontal wells with the liner string by mounting the hanger directly into a Casing. The hanger is provided with premium O-rings and glass-filled Teflon back-up rings to seal in the hydraulic cylinder. Sealing system has a pressure rating of 10,000 psi at 4000 F. A high-strength alloy cylinder provides maximum burst and collapse rating as per customer’s requirement/demand. The hydraulic version is ideal for liner applications where corrosionresistant alloys are incorporated in the liner casing. This could be installed on the CRA casing, which results in a huge cost savings when compared to a solid-body type hanger. The hanger is set by applying pressure through the run-in string. A setting ball is circulated or dropped to a ball seat in the landing collar. Applied pressure acts on an internal piston/setting collar, moving the slips up the cones to the set position. The Hydraulic Set Rotating Liner Hanger incorporates a tapered roller bearing assembly which allows the liner to be rotated in the set position while cementing the liner. The hanger body is furnished with higher group of API 5CT standard materials as well as with the end connections in compliance to API standards or any premium threads as per the customer’s requirement/demand. Materials suited for H2S or CO2 service are available on request.
