Abstract
An apparatus for testing a ring cut from a pipe, comprising: a body, an annular pressure member, which is expandable and is connected to a source of pressurised fluid, and one or more sensors for measuring strain and deformation of the ring and fluid pressure, wherein the body defines a substantially circular opening for receiving the annular pressure member and the ring, and the annular pressure member is provided, in use, between an inner surface of the substantially circular opening and an outer circular surface of the ring for applying pressure to the outer circular surface of the ring.

A method of testing a ring cut from a pipe using an apparatus, the method comprising:
- a. cutting the ring from the pipe;
- b. fitting the ring into the apparatus;
- and
- c. applying pressure using the apparatus and recording the strain and deformation measurements;
- wherein the apparatus includes:
- a body,
- an annular pressure member, which is expandable and is connected to a source of pressurised fluid, and
- one or more sensors for measuring strain and deformation of the ring and fluid pressure,
- wherein the body defines a substantially circular opening for receiving the annular pressure member and the ring, and the annular pressure member is provided, in use, between an inner surface of the substantially circular opening and an outer circular surface of the ring for applying pressure to the outer circular surface of the ring.
