A grooved pipe-joining system is one method of accommodating thermal expansion and contraction in HVAC systems.The FP-series of plaza deck expansion joints from EMSEAL, ensure that the joint is properly integrated with the waterproofing membrane while accommodating structural expansion and contraction movement of the split-slab plaza deck assembly.Because the joint bisects the entire structure, it marks a gap through all building assemblies–walls; decks; plazas or split-slab concourses; foundation floors and walls; roofs, planters, and green roofs; fire-rated demising walls and floors; interior floors; etc.It reduces stress on the piping system and provides a more compact, easy-to-inspect, and productive method of installation over other pipe-joining methods, such as welding or flanging.
In addition, with the grooved method, all sealing elements are combined within a metallic housing.
Inadequate accommodation of this movement can result in business risks caused by excess stress on the piping system, including: increased incidence of ruptures and leaks; increased stress on boilers, chillers, valves and other equipment and components; and increased downtime and labour expenses.
