Critical Piping

In power plant, there are some piping which carries steam at high pressure and temperature. And also there are piping which carry water at high pressure. These pipes carry the main cycle steam and water of the steam power plant. These pipelines are called Critical Piping. This piping is designed with very special care. The material selected for such piping has to withstand both high pressure and high temperature. They carry the main system fluid of the power plant. They often expand due to high temperature and thus need to have built in flexibility. Such piping systems are governed by guidelines and mandatory requirements. The most important codes used by power plant piping engineers are: ASME ANSI B31.1 – Power Piping Code and IBR – Indian Boiler Regulation.
