Steam pipe elbow bending radius
Thread Content
For the steam pipes inside the factory, with a pressure of 3.2 MPa and a temperature of 280°C, what size should the elbows be? Is 1.5D sufficient? Are there any standards that can be used as a reference?
Pressure determines the wall thickness, while temperature determines the material; your steam system is quite standard, so a 1.5D elbow would be an appropriate choice
This mainly takes stress calculation into account; if the stress is within acceptable limits, then there’s no problem, but if not, it needs to be replaced!
All the 3.5MPA steam in our facility uses 3D elbows
Sure, what role do you play in this project?
Either one is fine; it depends on the resistance calculation and stress calculation
