This standard specifies the basic parameters such as type, nominal pressure, nominal diameter, calculated heat transfer area, etc. of non-detachable spiral plate heat exchangers made of carbon steel and stainless acid-resistant steel. This standard applies to non-detachable spiral plate heat exchangers with a nominal pressure not greater than 1.6MPa, a nominal diameter not greater than 1600mm, and a nominal heat exchange area not greater than 120m^(2).
