摘要： The apparatus comprises a pipe PIG and a gauge. The PIG is for use with a pipeline and is of the type including: a body defining a longitudinal axis; and a pair of seals connected to the body and axially spaced apart from one another by the body. The gauge: has a longitudinal axis; has an outer periphery through which the longitudinal axis of the gauge passes centrally; has a central position relative to the body wherein the longitudinal axis of the body and the longitudinal axis of the gauge are at least substantially coincident; and is mounted to the body for generally radial movement relative to the central position.

摘要： A degradable plug device for a pipe has an outer plug body and an inner plug for preventing fluid flow through the pipe until the inner plug has been removed from the outer plug body. The outer plug body and the inner plug are of a degradable material. The inner plug has a chamber with at least one port to the exterior of the inner plug. The exposed surfaces of the degradable plug have a protective layer thereon. The inner plug is disposable in at least a first position, in which the inner plug prevents the fluid flow through the pipe. The inner plug is adapted to undergo, in use, a degradation initiation operation such that fluid is able to enter the chamber via the at least one port to initiate corrosion or dissolution of the inner plug from inside the chamber.

摘要： A pig has a body of resiliently compressible material extending along a central longitudinal axis. At least one strain gauge is embedded in the material of the body. The or each strain gauge extends transversely with respect to the central longitudinal axis and is arranged to deflect and elongate longitudinally with longitudinal deflection of a forward end of the body.
