Pipeline Thermal Expansion Boxes (TEBS)
Underground pipes are susceptible to damage caused by thermal expansion. Our thermal expansion boxes are engineered to protect underground pipes from potential damage caused by thermal expansion including circumferential (hoop), longitudinal and radial stress. They are a cost effective solution for protecting underground pipes from potential damage due to soil stresses and back fill operations. Product applications include:
- High temperature, insulated, closed hydrocarbon drain piping that is buried.
- Buried vessels – installed around the vessel heads to protect from deformation due to thermal expansion into the soil.
- Around piping that is buried and connected to nozzles in order to reduce the nozzle loads.
- Used at multiple locations where unrestrained pipe undergoes a directional bend, rises out of the ground or has a union (tie-in) with another pipe or fitting.
