Derivation of the Static Thrust Expression • Combined to obtain the thrust force

Presented herein is a general discussion of the nature of thrust forces as well as suggested approaches to the design of both thrust block and restrained joint systems for balancing these …

In these situations the designer should evaluate locations where encroaching restrained lengths exist and determine where any thrust force is coming from and how that force afects the …

Thrust Block – Bearing Construction Distribute load uniformly to bearing soils Align bearing face with pipe Preserve access to fitting and connections

Thrust blocks or anchor blocks are required on all unrestrained pressure pipelines at locations where thrust forces caused by internal pressures act upon the sides or ends of pipelines.

Actuator thrust is the required actuator force, and is what we need to determine. The figure above shows a general case where the force required by an actuator must be determined.

Calculating Thrust in a Pipe Determine inside diameter of pipeline in inches (divide by 2 for Radius) Determine maximum back pressure Calculate thrust pressure (Radius x Radius x π x …
