What Does
Pipe Rupture Mean?
Pipe rupture can be defined as damage to a pipe in the form of a break. This break can be caused by a variety of reasons including age, corrosion damage, excessive internal pressure, and ground surface settlement or heaving. Rupture of water, sewer and gas lines can be dangerous and even cause disruption and environmental damage.
Trenchless rehabilitation methods such as cured-in-place pipe (CIPP), pipe bursting and sliplining can be used to rehabilitate or repair such pipelines.
Trenchlesspedia Explains Pipe Rupture
Buried pipelines are subject to dead load from the weight of soil and standing structures over it, and live loads from moving traffic. If backfilling is not done adequately or is done with improper compaction, the soil can settle, increasing the pressure on the pipe. In areas with high ground water or high soil water content, the excess moisture content during wet seasons can cause the soil to swell up, creating an upward pressure causing the pipe to bend upwards.
Brittle pipes such as those of concrete and clay can rupture with such movements. Flexible pipe materials such as high density polyethylene (HDPE), polyvinyl chloride (PVC) and polyethylene (PE) can withstand significant movements due to their elastic property. Damaged pipelines can be replaced using pipelines made of these materials with trenchless rehabilitation methods.
