@PEDROPE52538638 Diossssss... Yo que quiero poner un cuadro en una pared de esas, pero desisto porque no tengo la energía de taladrar por lo DURAS que son jaja
Pro tip for engineers: Always verify your preload with real measurements for high criticality joints.
A very common method is UT. A little planning can prevent costly joint failures down the line.
Curious about the advancements in flange design methods? Watch this video for a high-level summary based around WRC 510 and PVP2007-26643.
Thankfully, we are continually addressing these in codes and standards such as ASME PCC-1 and VIII-2.
The bolting industry is evolving.
If you skip this preload or only go for the bare minimum, you risk losing seal integrity under real conditions. This practice isn't opinion—it's proven and is built into ASME and PCC-1 guidance. The calculations reflect how joints behave—not how we wish they would.
From years working on bolted joints, here's something most people overlook: During assembly, we intentionally preload every joint higher than what's needed just to make it seal. That extra load isn't waste—it's essential.
When a joint goes into service and faces pressure or temperature, some of that initial bolt load goes away. It's not a mistake; it's a result of forces acting against the joint. Internal pressure tries to push the flanges apart. Gaskets relax and creep, especially with heat.
