Thrust Blocks

(OP)
Does anyone have the definitive solution for the determination of pipe thrust forces and the design of thrust blocks?  I have seen many undocumented solutions but no definitive reference.  I am referring to fluid flow in steel pipes.

Thanks for answering.

For thrust blocks, even with steel pipe, I suggest using "Thrust Restraint Design For Ductile Iron Pipe" from the Ductile Iron Pipe Institute. See pages 2 thru 6 of this link
http://www.dipra.org/pdf/thrustRestraint.pdf

Use of thrust blocks assumes that the pipe itself makes no significant contribution to restraint - therefore the pipe material (steel, DI, plastic, fiberglass, etc.) is irrelevant.

RE: Thrust Blocks

As an alternative you could look at the following CIRIA Report 128, unfortunately though, its not free.

"Guide to the design of thrust blocks for buried pressure pipelines"
