| High Light | Thermal Oil Centrifugal Pump ，High Temperature Process Pump ，Heat Transfer Fluid Circulation | ||
Our thermal oil pump program originated from a 2014 collaboration with a European chemical engineering company that required a circulation pump for a synthetic heat transfer fluid system operating at 320°C continuous temperature in a polymer manufacturing process. The project's technical specification included a requirement that we had not previously encountered: demonstration of creep life analysis for the pressure casing at the design temperature, with supporting finite element analysis showing that casing stresses remained within the ASME Section VIII Division 2 time-dependent allowable stress limits for the specified design life of 100,000 hours.
This challenging requirement led our engineering team to develop a comprehensive elevated-temperature mechanical design methodology that has since been applied to over 60 thermal oil pump projects across chemical, pharmaceutical, plastics, and concentrated solar power applications.
The mechanical design of each high temperature centrifugal pump for thermal oil service begins with material selection based on the specific operating temperature and heat transfer fluid composition. For synthetic organic heat transfer fluids at temperatures up to 350°C, 1.25Cr-0.5Mo alloy steel (ASTM A217 Grade WC6) provides an optimal combination of elevated-temperature strength, oxidation resistance, and cost. For applications exceeding 350°C or involving particularly aggressive synthetic fluids, we upgrade to 2.25Cr-1Mo (ASTM A217 Grade WC9) or 316H stainless steel.
