Scope
This document specifies the general principles and requirements for the selection and acceptance of injection mixing devices used for heating. This document applies to single-stage/multi-stage steam-type injection mixing devices (including but not limited to pressure matching devices, steam injection pumps, steam-steam injection devices, etc.) with a working pressure not exceeding 35MPa and a working temperature not exceeding 625℃. For new types of multi-channel and composite adjustment injection mixing devices, the implementation can be carried out in accordance with the relevant provisions. Note: In order to avoid confusion, in this document, "standardized documents" are referred to as "documents".
