Although there are many types and brand name of liner hanger system, basic of the equipment and operations are same. After get trained from different service provider and conducting many kind of liner hanger operation I was assigned to teach fundamental of liner system to the related engineers within the company. Linked presentation is from the training session and shares the fundamental knowledge of liner hanger system for interested people.

11. • Other Equipment Rating
 All equipment must have at least liner
hanger strength values
 For all rating parameters (collapse, burst,
tensile load etc.) the weakest point in
design should be determined
 There should not be an ID constriction
affecting the operation
