Available services

Nowadays, boilers operable under the condition of high temperature and pressure steam called "ultra-supercritical pressure" steam have prevailed in order to improve power generating efficiency of the coal-fired power plant because of increase in the fuel cost and from point of view of conservation of environment.
The steam heating piping for the "ultra-supercritical pressure" boiler uses a highly efficient stainless boiler pipe, and it is used under extremely severe condition.
To withstand such condition, there is a boiler having boiler pipes with the life extended by application of shot peening to the internal surface.
