How to install a corrugated expansion joint on a vertical pipe section
Thread Content
I am currently working on the design of a steam pipeline with a diameter of 219*6, operating at a temperature of 210° and a pressure of 1.2 MPa. Due to process requirements, this steam pipeline needs to rise from a height of 6.5 m to 14 m. I intend to use metal bellows compensators to account for the thermal expansion of this vertical pipeline. However, according to the information I’ve found, there are strict requirements regarding the distance between the metal bellows compensators and the surrounding guide supports: 4D from the first guide support and 14D from the second guide support. Are there any specific requirements for installing bellows compensators in this vertical section? In particular, I’m not sure how to set up these guiding brackets. Please help me figure it out; thank you!
With your specified diameter and pressure, using an axial internal pressure type expansion joint, the internal pressure force acting on the mounting frame alone will be around 6.4 tons. It is recommended not to install expansion joints on vertical pipe sections; instead, a large tie rod expansion joint that can absorb lateral displacement should be used on the horizontal pipe sections on either side of the vertical sections. There is no internal pressure thrust, and there are also fewer constraints imposed by the pipe support installations.
