This standard is based on Section 2.5\Mud Pump Parts" of the American Petroleum Institute Standard API Spec 7K "Drilling Equipment Specification" (1994 Edition) and has revised SY5002~5019-80. According to the current domestic situation, when adopting Section 2.5 of API Spec 7K, the plug rod, intermediate rod, nut and lock nut are only connected by cone: cylindrical thread, and the cylindrical thread is deleted. Connection (inconvenient installation and disassembly). In the section "Piston rod and active core hole", the single-acting content (not belonging to the double-acting pump) was deleted. This standard will take effect from: At the same time replace SY5002~5019-80 This standard is proposed and managed by the Jinguo Petroleum Drilling Equipment and Tools Standardization Technical Committee. Drafting unit of this standard: Baoji Petroleum Machinery Factory. The main drafter of this standard Pu Rongchun
