AISI Alloy Steel Oil Drilling Tools Radial Shock Absorber 1170mm
Length
Introduction of Radial Shock Absorber
For the drill stem testing operation, there are two types of shock
absorber: Vertical shock absorber and radial shock absorber, which
is to protect pressure-measuring equipment during testing
operation.
Normally the radial shock absorber use with the vertical shock
absorber together and it is always located below the vertical shock
absorber. The radial shock absorber mainly composed by radial shock
absorption component and axial slide component.

Operation
In radial shock absorbers, spring-loaded drag blocks absorb radial
shock waves transmitted through the TCP perforating. The vertical
shock from axial slide can be transferred to the vertical shock
absorber, a part of shock will be absorbed by axial slide movement
and the shear pin effect, so that the condition of radial shock
absorber component and inner-wall tubing are relative stable.
