Stress analysis of 48 kg LPG cylinder

Abstract

Objective of this research was to analyze the stress of a 48 kg LPG cylinder designed under Thai Industrial Standard TIS 27-254. The design was employed by using test pressure of 3.3 MPa and the tank wall thickness of 2.65 mm which provided the maximum tensile strength of 429.3 MPa, yield strength of 286.2 MPa and burst pressure of 5.99 MPa. The material used to produce the gas cylinder was SG295 grade steel with a yield strength of 300 MPa and a maximum tensile strength of 440 MPa, which covered the design requirements. The research results were found that at the 85 percent of cylinder volume, gas density of 0.54 kg / l, liquid height of 0.9367 m and gauge pressure of 0.073 psi gave circumferential and longitudinal stresses of 0.0357 MPa and 0.0178 MPa, respectively. According to analysis results of finite element method revealed that the stress concentration area was the circumference at the center position of the tank with the highest value at the welding joint.

Analisis Kekuatan Tabung Gas LPG Kapasitas 12 Kg Berbahan Cast Carbon Steel Menggunakan Metode Elemen Hingga

“…Gas ini digunakan luas dalam kehidupan sehari-hari, terutama dalam aplikasi memasak dan pemanasan. Mengingat pentingnya keselamatan dan keandalan tabung gas LPG, analisis kekuatan menjadi faktor yang sangat vital dalam merancang dan memproduksi tabung yang aman serta tahan lama (Sitthipong et al, 2020). Dalam studi ini, dilakukan analisis kekuatan pada tabung gas LPG berkapasitas 12 kg dengan material cast carbon steel menggunakan perangkat lunak SolidWorks menggunakan metode elemen hingga.…”
