Analysis of Material and Heat Treatment of the High-Pressure Fracturing Pump Valves

Abstract:

Fracturing pump valve's failure, except wear and tear factors, and also decided by the scope of it's contact stress, material and heat treatment in technology. Through the analysis of these, some conclusions had been found: The content of remnant austenite would be affected the performance of wear resistance, and the core hardness would be directly affected the working life of it. If the choice of the material and heat treatment technology was not been suitable, and the core intensity was not enough, it could loss the capability of sealing. According to the failure mechanism, used low chrome(nickel) steel, and the heat treatment of carburize+heat hardening+low-temperature tempering was reasonable.
