Calculation conditions for pipe expansion
Thread Content
Dear sea friends, does anyone know the calculation criteria for pipe expansion? Like temperature conditions or something else? Which specification contains relevant information? I currently have a pipeline with a temperature of 40°C, in DN150 and DN80 sizes, with a length of around 100+ meters, and it features L-bends for natural compensation Is a flexibility analysis required? Thank you!
Material expansion coefficient * Tube length * Temperature difference; 40 degrees, right? It’s not necessary to use that value
Tubes at 40 degrees don’t need to be considered, and they are also small tubes
Pipes at 40° do not require stress prevention
Has the environmental temperature difference been taken into account? In the north, the coldest temperatures can reach minus 40 degrees, while in summer they can be as high as nearly 30 degrees.
At such a low temperature, stress analysis is not necessary.
