Carbon Steel Mechanical Liner Hanger, For Cement Plant

This Liner Hanger is set mechanically with either right or left- hand rotation, depending
on the type of setting tool or design. Staggered cone design gives maximum bypass
area to ease running in and circulation. Automatic J- cage allows hanger to return to the run-in position, should the hanger set prematurely while running in the well. The slip cage contains a “J” slot and high strength drag springs to manage the movement of the slips into contact with the cones. Mechanical Set Liner Hanger are set through manipulation of the work string (pick-up & 1/4 right hand turn) line up the cones and the slips, and a further slack off sets the slips onto the casing wall. In liner hanger we have four versions e.g.: Type-I [Single Cone & Non rotational], Type-II [Double Cone & Non rotational], Type-III [Single Cone & rotational] and Type-IV [Double Cone & rotational] to suit various applications. 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.
