New freeze pipe systems for nitrogen freezing
Abstract
A number of field and laboratory experiments have been carried out using new kinds of freezing pipe systems. These systems particularly enable freezing to be performed in stages. They further enable liquid gas consumption to be minimized. One system is particularly suitable for shaft freezing while another lends itself to tunnelling.
