    摘要： The present disclosure relates to a pig which is insertable at least partly within a fabric liner sleeve located in a duct and which is capable of heating the liner sleeve in situ in the duct to melt thermoplastic material of the liner sleeve to form, on subsequent cooling of the melted thermoplastic material, a rigid liner in the duct. The pig comprises: a gas inlet (1008) for receiving pressurised gas; a heating chamber (17) in which the pressurised gas is heated; and a gas outlet (1009) via which pressurised gas heated in the heating chamber (17) is deliverable to the fabric liner sleeve.
    The pig comprises a tree diffuser (15) located in the heating chamber (17) via which pressurised gas can be delivered into the heating chamber (17).
    The tree diffuser (15) has a plurality of branch pipes (A,B,C) each comprising at least one gas delivery aperture, each branch pipe (A,B,C) extending outwardly from a trunk portion of the tree diffuser (15).

    摘要： An untethered in-line inspection tool for the non-destructive testing of a tubular test component is described which comprises one or more partial saturation eddy current testing (PSET) modules configured to locate with an internal surface of the test component. The one or more PSET modules comprise a variable strength permanent magnet for generating a variable DC magnetic field within the test component and at least one eddy current sensor. Having an in-line inspection tool that employs PSET techniques allows the in-line inspection tool to operate with an increased range of pipeline types. For the detection of cracks the in-line inspection tool may also comprise one or more crack detection modules. The in-line inspection tool further comprises one or more battery modules. Employing a dedicated battery module removes any need to employ an umbilical or wireline in order to provide power to one or more electromagnets.
