1 Scope This specification specifies the selection of petrochemical pipe materials, as well as the selection requirements and calculation methods of piping components. This specification is applicable to the selection of petrochemical unit-used piping components with nominal pressure not greater than PN420 (CL2500) and design temperature not exceeding the allowable service temperature range of the materials. It is inapplicable to nonmetallic pipes. 2 Normative References The following referenced documents are indispensable for the application of this specification.
