Dalam aplikasi bidang teknik, sangat sering digunakan bahan logam terutama besi sebagai bahan pembuatan pipa. Salah satu manfaat pipa besi yaitu dalam proses transfer gas. Dalam proses tersebut, gas serta pipa transfer sangat rentan terhadap panas. Skema beda hingga yang diterapkan pada metode numerik Crank-Nicoson memiliki tingkat ketelitian yang sangat baik. Skema tersebut digunakan untuk analisis proses penyebaran konduksi panas pada pipa besi yang berisi gas oksigen. Proses penyebaran panas pada pipa besi terjadi dengan mempertahankan syarat batas yang telah ditentukan.

The heat conduction equation is a parabolic differential equation and a type of second-order linear partial differential equation. By applying the finite difference scheme in the Crank-Nicolson method, the numerical solution of the heat conduction equation can be calculated. Obtaining numerical solutions with a high level of accuracy, Richardson extrapolation is required. The Crank-Nicolson approach scheme has a high level of accuracy, because the gap between numerical and analytical solutions is very small. Richardson extrapolation greatly influences the accuracy of numerical solutions, because the gap between analytical solution and numerical solutions with Richardson extrapolation is smaller than disparity in numerical solutions without Richardson extrapolation.

“…The transfer of energy that occurs only due to temperature differences is called heat flow or heat transfer, while the energy that is transferred is called heat. Energy transfer occurs from a high-temperature system to a low-temperature system [4]. Heat transfer will occur if there is a temperature difference between the two parts of the object.…”

Thermal conductivity is the value of a material's ability to conduct heat. Heat transfer occurs due to the difference in temperature found in an object. Heat transfer can take place in three ways, namely conduction, radiation and convection. The purpose of this study was to determine the conduction heat transfer rate for 3 solid cylindrical materials, namely aluminum, iron, and brass. by varying the temperature 50 ℃, 55 ℃, 60 ℃, 65 ℃, 70 ℃, 75 ℃ and 80 ℃. The working principle in this experiment is to prepare 3 variations of solid cylinders, then place them on a thermal conduction trainer by adjusting the temperature of the test on the thermocontrol display (T1) in stages and the test results are obtained as shown by a digital thermometer (T2). From the test results, the results of the heat transfer rate have been found, for the metal material that has the greatest heat transfer rate is aluminum with a heat rate value of 479.7 Watt at 80 ℃, the second largest heat transfer rate value is aluminum with a heat transfer rate of heat is 299.7 Watt at 80℃ while for the material the smallest rate is found in iron material with a value of 214 Watt at 80℃. The average heat transfer rate for aluminum is 325.5 Watt, for an average heat transfer rate for iron is 147.1 Watt, and the average heat transfer rate of brass is 218.5 Watt.
