“…SS304 stainless steel tubing was used, with an operating temperature and pressure of 140 °C and 1 MPa with an allowable stress of 137 MPa the pressure results using L and Z type configurations between equipment connection are 174.32 and 153.12 MPa, respectively. Verma et al [8] determined a 3D modeling design for a closed-loop, high-pressure, high-temperature helium gas facility. The facility was designed to test several gascooled mock-ups, producing considerable thermal deflections and expansions in the piping system.…”

En la actualidad las tuberías son el principal método de transporte de fluidos de un lugar a otro, dentro de una planta industrial. La presente investigación estudia la configuración de tuberías de un sistema de bombas de transporte de hidrocarburo. Se realizó una investigación para identificar las diferentes cargas presentes en diseños de los sistemas de bombas, debido a efectos de peso propio y térmicos operativos, con el fin de reducir los esfuerzos, desplazamientos que actúan en las tuberías, garantizando su integridad mecánica como la seguridad de equipos y personal de planta. El desarrollo del modelo y análisis se realizó en el software especializado Bently AutoPIPE en condiciones estáticas, los datos operativos de temperatura y presión son 100 °F y 320 psi respectivamente. Para el análisis, se emplearon dos modelos de configuración; tuberías con sistema rígido y flexible, permitiendo comparar resultados y validar que los esfuerzos en tuberías y boquillas de bombas se encuentren dentro de las cargas admisibles de acuerdo con las normas ASME B31.3 y API 610. Con base en los resultados del análisis, los esfuerzos en sostenido y térmicos son 16.3 y 14.4 ksi, valores que representan aproximadamente el 75 % del esfuerzo máximo del sistema

The thermal expansion can lead to the high stress on the pipe. The problem can be overcome using expansion loops in a certain length depending on the material’s elastic modulus, diameter, the amount of expansion, and the pipe’s allowable stresses. Currently, there is no exact definition for the dimension of expansion loops design both for loop width (W) and loop footing height (H) sizes. In this study, expansion loops were investigated with using ratio of width and height (W/H) variations to understand pipe stress occurring on the expansion loops and the expansion loops’ safety factor. Relationship between non dimensional stress on the expansion loop pipe was studied numerically by finite element software on several working temperatures of 400oF, 500oF, 600oF, and 700oF. It can be found that stress occurring on the pipes increases as the increases of W/H of the expansion loops and results in a lower safety factor. The safety factor of the expansion loops pipe has a value of 1 when the ratio of loop width and loop footing height (W/H) value was 1.2 for a 16-inch diameter pipe. Stress occurring on the pipe increases with the increase of the working temperature. Expansion loops pipe designed for 400oF can still work well to handle thermal extension pipe occurring on 500oF.
