PE Thrust Block Support - pipe in Mexico

PE Thrust Block Support PE pipes and fittings joined by butt welding, electrofusion, or other end load bearing joint system do not normally require anchorage to withstand loads arising from internal pressure and flow. Thrust blocks are only required for Vinidex PE pipes in pressure appliions where the joint types do not resist longitudinal loads. …
