Design of pipe rack for 330°C heat transfer oil
Thread Content
As shown in the diagram, the four dn250 heat transfer oil pipes are installed in a pipe tray, using guide supports; the length from north to south is 98 meters, and the length from southwest to northeast is 51 meters. 1. Due to the limited space available for the pipe rack, a π-shaped pipe design with a minimum arm length of 750 mm was used. However, if it is not secured at the turn on the south side, an increase in temperature of 330° will cause the four pipes to shift to varying degrees. Many options were ruled out; should an expansion joint design be used to prevent significant displacement of the pipelines on the pipe rack, and is this in compliance with relevant standards?
I’ve been learning about cost estimation recently. In addition to the wave-shaped type, expansion joints also come in filler-type, L-shaped, spherical, and square types. I’m not sure if all of these are used in practice
