Accommodating building deflection

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.A grooved pipe-joining system is one way of accommodating thermal expansion and contraction.These functions include: waterproofing, resisting hurricane-force wind and water, air-barrier sealing, sound proofing, and in many cases fire proofing.Additionally, because wall expansion joint materials interface with facade materials that should not be penetrated with fasteners, non-invasive anchoring is a desirable feature.Victaulic’s Larry Thau explains the technique’s design benefits and mechanical advantages The key to effectively accommodating thermal expansion and contraction in a building services system is to allow the predictable, controlled movement of piping.This can be done in a variety of ways, and the selection of a specific method depends upon the engineer, the type of piping system and the project parameters.This causes the “expansion joint” to close down, thereby compressing the expansion joint system installed in the gap. This structural opening bisects not only the facade but the structural building elements as well.

All materials, including pipe, experience dimension changes as a result of varying temperatures and their coefficient of expansion.This often occurs at directional changes in the pipework.‘Bowing’ can also develop at the mid points of long, straight pipe runs, resulting in stress on the piping system and equipment.When a system is subjected to changes in temperature, it may experience horizontal movement, vertical movement and angular deflection simultaneously.Additional strains on the piping system vary based on whether the piping is vertical or horizontal.

Additional strains on the piping system vary based on whether the piping is vertical or horizontal.

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.
