How to use LAPPED FLANGE?

I do not get to the bottom of this and I have tried all sorts things in Plant 3D.

 

My spec has got LAPPED FLANGE (RF/LF), STUB END (RF/BE) and all valves are RF/RF.

 

The STUB END in Plant 3D has got a LAP connection by default. In the model this STUB does not even show a connection point on the flange side. It appears as a connector. How can I make this work?

 

Pic 1 shows no snap-point at flange side

Pic 2 shoes snap-point on the welded side of flange

Are you trying to connect to an END osnap? Try the NODE osnap.

Thanks for your suggestion.

 

The components connect when I use the NODE snap ut I get error message and there is a leakage. See attachment.

The error message is telling you to check the 3 properties. Check one against the other and see what the difference is. When you find the conflicting properties, you'll have to take steps to rectify it, either by editing the properties again or the connection rules.

Hi Trygve,

 

I have looked for the properties of the flange and valve which have attached here. So for a valid connection it is defined in your project that the NominalDiameter, the PressureClass and the Facing of the connected ports are the same.

 

For your flange I can see that the properties are

for the port S1:

NominalDiameter = 8

PressureClass = 150

Facing = FF

 

for the port S2:

NominalDiameter = 8

PressureClass = 150

Facing = no value

 

For your valve the values are

for the port S1:

NominalDiameter = 8

PressureClass = 150

Facing = RF

 

NominalDiameter = 8

PressureClass = 150

Facing = RF

 

So the facing for the valves and the flange are different. You have to redefine your properties here, so a match is possible.

 

Please, inform us if we could help you.

 

Regards

I have found a solution to this problem.

 

The thing is that the lapped flange is RF in my piping spec while the default Plant 3D catalog only offer FF facing for lapped flange. Did a duplication of the FF lapped flange and changed facing to RF.

 

Voilà !!!!
