Apparatus for squeezing pipes and method of use

摘要

An apparatus for squeezing pipes, comprising a first jaw having a first squeezing surface and a second jaw having a second squeezing surface. The first jaw and the second jaw are interconnected for relative displacement at proximal ends through a first shaft of the apparatus and at distal ends through a second shaft of the apparatus. The first squeezing surface and the second squeezing surface are separated by a gap adapted to receive a pipe therein. The first jaw is rotatable with respect to the first shaft and engageable with the second shaft such that the apparatus is mountable about a pipe with the pipe being positioned in the gap between the first and the second shaft. Actuation means are provided for axially displacing the first shaft to reduce the gap to squeeze the pipe between the first squeezing surface of the first jaw and the second squeezing surface of the second jaw to block at least partially fluid flow in the pipe, wherein at least one of the first and second jaws bends at a given level of squeezing of the pipe whereby greater pressure is applied on cross-sectional ends of the pipe being squeezed.
