Utilization of phase change for sealing and pressurization of tubular elements

Abstract EN

The process of freezing of water and blockage of pipes are summarized.

Current research on freezing and its applications are briefly reviewed.

Design concepts are introduced for doing work by utilizing pressures caused by ice blockage.

Several conceptual designs are presented for experimental setups for the isostatic pressurization of thin walled tubes.

Potential practical uses of pressures generated by freezing of water and blockage are mentioned.

These include the burst testing of tubes made of composite materials, compaction of powders, as well as the plastic deformation of thin tubes.
