Abstract: A coupling assembly is provided having a first member and a second member. The first member is able to be coupled to the second member by relative movement along a coupling axis. In use, a tension component carries the axial tensile load of the coupling assembly. In order to decouple the coupling without removing the tension component, it is necessary to apply sufficient tensile force to fracture the tension component. Thus the tension component is designed to fracture in to two parts along a single fracture. Advantageously, because only a single tensile component is used, the precision in the set force necessary to decouple the two parts is improved. The coupling assembly is particularly suitable to joining two part of an oil pipeline in order to provide a safety, breakout function.

Abstract: A coupling assembly (100) is provided having a first member (110) and a second member (120). The first member is able to be coupled to the second member by relative movement along a coupling axis. In use, a tension component (140) carries the axial tensile load of the coupling assembly. In order to decouple the coupling without removing the tension component (140), it is necessary to apply sufficient tensile force to fracture the tension component. Thus the tension component is designed to fracture in to two parts along a single fracture (142). Advantageously, because only a single tensile component is used, the precision in the set force necessary to decouple the two parts is improved. The coupling assembly is particularly suitable to joining two part of an oil pipeline in order to provide a safety, breakout function.

Abstract: A coupling comprising a tubular inner member (9) defining a socket dimensioned to receive a pipe to be connected to the coupling. The inner member (9) is positioned within a tubular body (1) to define a closed annular chamber, and an inlet (2) is provided tough the body so as to communicate with the chamber. In use, pressurised fluid such as a setting resin is introduced through the inlet (2) into the chamber. The pressure of the introduced fluid is sufficient to cause the radially inwards deformation of the tubular inner member (9) so as to grip the pipe (13, 14) which is received within the socket. Pressure may be applied up to a predetermined limit, or until seal failure.
