How to consider the thickness of high-pressure pipeline flanges
Thread Content
When designing a transport pipeline with a design pressure of PN100, can loop flanges be taken into consideration? How to choose. How is thickness calculated? Are there any experts in this area?
The loop cannot withstand such high pressures; there is a corresponding standard for flanges of PN100, which can be referred to in HG/T20592-2009
But how should the loop thickness be designed when a live loop is actually needed?
What material? Just weld a neck flange directly
By standard, the maximum pressure of the loop is only up to PN40; if it’s PN100, you need to consider carefully the pressure level and the performance of the sealing surface
This approach carries huge risks; think it through before drawing any conclusions~~~
Calculate the flange thickness by yourself and use non-standard flanges.
Flange thickness is not the most critical factor; what’s really important is leakage at the sealing surface. You don’t have enough pre-tightening force to ensure the sealing of the sealing surface.
