Mechanical Liner Hanger System

MACKERAL’s Mechanical 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.

Features / Benefits:

• Open-bottom J-cage, available in right or left-hand set.

MI 5166 MECHANICAL RELEASE LINER HANGER RUNNING TOOL
MACKERAL’s Mechanical release running tool is an industry-standard rotational release running tool. With no rotational drive capability, this tool simply conveys the liner assembly and then is released with right-hand rotation after the hanger has been set. Designed to release in compression, this tool may be run in vertical, high-angle or horizontal wells with a high degree of confidence. As a service tool, the mechanical release running tool is a heavy duty design and construction ensures a long, usable service life. Standard configuration is with an API drill pipe box cementing seal joint box for direct connection to a retrievable seal joint, drillable seal joint, solid bushing or inverted cup tool. It may be run in conjunction with various setting tools to run liner top packers or tieback seal nipple packers.
