These regulations stipulate the requirements for the design, manufacturing, inspection and testing of Ding Petrochemical reciprocating claw machines and their driving machines and auxiliary equipment. These regulations apply to the engineering design and equipment procurement of petrochemical reciprocating compressors. This regulation is applicable to power air compressors with an exhaust pressure of less than 0.9 MPa (G), compressors driven by internal combustion engines or reciprocating steam engines, and small high-speed compressors used in oil fields. Reciprocating compressors higher than 31.5MPa(G) or ultra-high pressure (>100MPa(G)) may refer to the implementation.
