Open Plant Modeler / Spec generator: Valve with flanges connecting with slip on Flange including bolts, nuts and gasket

Jukka Waarni

I have a problem how to automatically integrate slip
on flange (collar + loose flange) with bolts, nuts and gaskets when placing a
valve (ball valve etc.) with flanges or wafer valve (butterfly valve or check
valve for example). What are the settings must to have so that slip on flange
with bolts, nuts and gasket automatically appears to design? I know that
setting AutoFlange must be set ON, so that flanges are coming to design. I have
done it like that but slip on flanges does not appear. Maybe it needs some modifications
in catalog where slip on flange exists?

I have got flanges with bolts, nuts and gaskets by using Lap Joint Stub End. My opinion is that it is not the right one when modeling loose flange with collar. At least loose flange looks very strange for me. In a picture below I have taken Lap Joint Stub End. After that I changed loose flange iwith PAINT software to show to show how this connection must exist.

This is how I want valves (etc.) with loose flanges with collar to look like:

One questions regarding collar for loose flange: how
can I get collar diameter connecting to pipe equal with pipe outside diameter. Diameter is now something strange (more than pipe OD) with decimals.
How can I have butt weld mark between collar and pipe?

    Hello Ian,
     
    I do not know if both (lab-joint stub end or slip on flange) are not right ones for me (after searching web and seeing some images).
    Slip om flange:
     
     
    Lab joint flange:
     
     
    The loose flange with collar (for austenitic stainless CrNi-steel and austenitic stainless CrNiMo-steel) that I need is according to standard EN 1092-1, types 02 & 35. For smaller pipes can be used type 11, too. As you can see inside red rectangle below (table is only for PN10 but form of the loose flange is similar for PN6, PN16, PN25, and PN40), loose flanges are without a “neck”. There are more flange types 11 for pressure classes PN25 and PN40 and for PN63 type 11 is the only possible.
    If needed I can send you collection of the EN flange tables.
     
    Normally collars and flanges are provided from same vendor. Material of the collar is according to pipe material (austenitic stainless CrNi-steel and austenitic stainless CrNiMo-steel) and loose flange material usually is steel (P265GH) for saving money.
     
     
     
    About welding mark: I want it to be there. There is always a welding connection between a collar and pipe.
