Externally Pressurized Type
Externally pressurized type expansion joint is advanced product as a result of research activities about the transmission part of high pressure steam and high temperature water. It is more excellent than more economical than Internally Pressurized expansion joint and widely used in an advanced country. Especially, It is evaluated as a suitable product for construction gas fired combined cycle power plant.
