It is required to furnish thrust restraint at mechanical joints. Mechanical restraints and thrust blocks are both widely accepted forms of restraint, so either one is acceptable. It is not required to furnish both, but I've seen many applications where both methods were used together for one reason or another.

I am working with underground pipe PVC DR14 C900 for a fire sprinkler system and I do understand that if we use restrainers (for example: SIGMA PV-LOK-PVM and PVP) in/near the MJ fittings, we do not need to use thrust blocks. ¿Is this true? I would appreciate if someone could share an Excel file to calculate the thrust block size. Thanks Best regards! _______________________ Gerzayn Fuentes CEPI - Mexico T. + 52 (81) 1766-0800 _______________________________________________ Sprinklerforum mailing list [email protected] http://lists.firesprinkler.org/listinfo.cgi/sprinklerforum-firesprinkler.org _______________________________________________ Sprinklerforum mailing list [email protected] http://lists.firesprinkler.org/listinfo.cgi/sprinklerforum-firesprinkler.org
