Repair method of cast steel member

A repair method of a cast steel member having a crack formed on a surface of the cast steel member includes: forming a recess having a wedge-shaped cross section that widens in a depth direction of the cast steel member by cutting the cast steel member from the surface of the cast steel member to a predetermined depth so as to include the crack; pushing and embedding a repair member made of a metal material more flexible than the cast steel member into the recess formed in the recess forming; and diffusion-bonding the repair member to the cast steel member by heating a boundary between an exposed surface.. . ...

Remaining life estimation method for estimating remaining life of high-chromium steel pipe

An aspect of the present disclosure is to precisely define a constant value used in the monkman-grant analysis, when estimating remaining life of a high-chromium steel pipe through which high-temperature and high-pressure fluid is allowed to flow. A remaining life estimation method according to the present disclosure is particularly characterized in that a step of obtaining a constant on an accelerated creep test is performed in which a constant indicative of the product of a strain rate and a rupture time in the monkman-grant analysis is obtained by multiplying a first coefficient to transform uniaxial rupture ductility into multiaxial rupture ductility, the uniaxial rupture ductility being obtained from a specimen of the high-chromium steel pipe, a second coefficient to amend consumed life of the specimen, and a third coefficient to amend a measured pressure into an assessment pressure.. ...

Repair method for cast steel member

A repair method for repairing a crack generated to a cast steel member due to a thermal stress includes removing a part of the cast steel member including the crack at a surface of the cast steel member to form a recess, fitting into the recess a first repair member that is made of a metal that is more flexible than the cast steel member and that is weldable to the cast steel member, and spot welding the first repair member to the cast steel member.. . ...

Guide tube for guiding cable of internal observation device and cable guiding method

A guide tube guides a cable of an internal observation device into a pipe bore. The cable is pushed into the pipe bore to force an observation image capturing part provided proximate a tip end of the cable to approach a portion to be observed when performing internal observation of the pipe bore of a pipe-like structure with the internal observation device. ...

Distance measuring apparatus and distance measuring method

A distance measuring apparatus includes a reference member that is installed on a surface of a first metal member; a range finder that measures a distance to the reference member; and a mounting member to which the range finder is placed. The mounting member is installed on a surface of a second metal member coupled to the first metal member via a weld. ... The Chugoku Electric Power Co Inc

Heat exchange structure of power generation facility

A heat exchange structure of a power generation facility including a piping system that is embedded in a reinforced concrete underground structure that is integrally formed with the power generation facility, and a heat medium that is fluid and is stored in the piping system. The piping system circulates the heat medium used for heat exchange in the power generation facility.. ... The Chugoku Electric Power Co Inc
