Mar 4, 2011 · Hi Everyone, In recent design of thrust blocks for a fireline installation, I came across values reported on the NFPA 24 code which raised a few questions. More specifically …

Mar 19, 2012 · What is the specific pipeline thrust focus you are in the process of blocking (from the shape of the block and your inquiry about a collar around the “pipe” you describe, it kind of …

Apr 15, 2015 · Restrained joint systems function in a manner similar to thrust blocks, insofar as the reaction of the entire restrained unit of piping with soil balances the thrust force. The …

Sep 2, 2011 · I'm reading that to design a thurst block both static pressure and flow velocity must be account for. Flow velocity I get, but I can't envision how static pressure inside a pipe would …

Sep 1, 2011 · Thrust blocks have of course often been used for buried service, where one common design objective is to figure out how large a block bearing area must be constructed …

Apr 25, 2011 · The pressure wave moves in both directions, so a single thrust block might have straps for the tension and a big concrete block to spread out the compression load. I could be …

Feb 11, 2011 · Why is it that some municipalities demand both joint restraint and thrust blocking? I guess thrust blocks can be altered or removed during subsequent work on other utilities. So …

Apr 25, 2011 · Based on the example drawing, it seems to me as if anchor bolts are not considered when design thrust block supports. Would this be an accurate statement? Since …

Mar 7, 2017 · Can somebody explain to me when thrust blocks are required on underground piping? For example, I have a 6" fire water storage tank fill line where the piping drops …

Mar 1, 2007 · No thrust blocks, as the thrust load is transfered through the fused joint and is balanced by axial stress in the pipe. Axial stress in buried pipe is eventually disipated by …
