nominal diameter / od plastic pipes

[M-BRF]

when the program draw pipe draws on the nominal diameter.
That's good because when you draw steel pipe referred everything to ND, but when we draw some plastic pipe all is based on the OD.

can make any spec as a reference the pipe Matching and the PIPE OD SIZE selector ribbon type the OD?

example, I hope to describe it well as it is a bit complicated: the pipe I have to draw it from OD 50 mm (2 ") but in HDPE PIPE SIZE SELECTOR not appear, I have to find its equivalence with the nominal diameter 1 1 / 2 ".
if I want the type the PIPE OD SIZE SELECTOR on the spec I have to write that dametro OD and the same nominal diameter is 50 mm (2 ") but the program thinks I am referring to the nominal diameter valves and seeks , Victaulic nominal diameter etc. 50 (2 ") OD 63 mm (2 1/2") nominal diameter always higher

when plastic pipes drawing ever I have to do the mental equivalent that if I want to draw outside diameter 50 millimeters I have to select in the PIPE SIZE SELECTOR 1 1/2 "

fix a little problem changing the BOM of the planes that enter the ISO SIZE LONG DESCRIPTION LONG DESCRIPTION not the FAMILY and OD instead of ND

you do in these cases?

greetings and sorry if the English translation is wrong help me Google Translate

-------------

cuando dibujamos tuberia el programa toma como referencia el diametro nominal.
eso esta bien porque cuando dibujamos tuberia de acero va referida todo al ND, pero cuando dibujamos alguna tuberia de plastico todo va referido al OD.

se puede hacer que alguna spec tome como referencia el Matching pipe OD y que el PIPE SIZE SELECTOR  de la ribbon escriba el OD?

ejemplo , espero poder describirlo bien ya que es un poco complicado: la tuberia que tengo que dibujar es de OD 50 milimetros  (2") PEHD pero en la PIPE SIZE SELECTOR  no aparece, tengo que buscar su equivalencia con el diametro nominal 1 1/2".
si quiero que en la PIPE SIZE SELECTOR escriba el OD en la spec tengo que escribir que el dametro OD y el diametro nominal sea el mismo 50 milimetros (2") pero que el programa piensa que me estoy refiriendome al diametro nominal y busca las valvulas, vitaulic etc de diametro nominal 50 (2") od 63 milimetros  (2 1/2") siempre un diametro nominal superior

cuando dibujo tuberias de plastico  siempre tengo que hacer la equivalencia mental de que si quiero dibujar diametro exterior 50 milimetros tengo que seleccionar en el PIPE SIZE SELECTOR  1 1/2 "

soluciono un poco el problema al cambiar el BOM de los planos ISO que escriba la LONG DESCRIPTION SIZE   y no el  LONG DESCRIPTION FAMILY y el OD en lugar del ND

que haceis en estos casos?

Hi,

At the moment you will need to create your own catalog for this. The easiest way would be to use the "New Catalog Builder" in Plant 3D 2013.

Alternatively if you want to request a new content pack please check the below link .

Do mention the specific standard/manufacturer you are looking for, if any.

Thanks,

Dan

Whenever I use to work with steel and plastic pipes, we just use to have the ND of the plastic pipes match the ND of the steel pipes. This way the DN matches across the two pipe specs, although one is based on a ND, and the other an OD.

The process engineer also had a matching values table in the specs, so that explained to everyone what plastic pipe OD was related to which DN size.

Hope this makes sense.

Hi Tomislav,

Apologies for reviving an old thread, but is this still the case when using Plant 3D 2022? i.e. do you still model plastic pipe with the same ND as the steel pipe?

Cheers

@M-BRF please see the below link to add your custom sizes in system.

Thanks @rajendra.prajapat but will it help when, as @M-BRF said, some sizes are the same between plastic (HDPE) od and steel pipe dn but have different bore sizes. 50mm Plastic pipe has the relevant bore size to 40mm Steel pipe, so if you map 50mm plastic pipe and 40mm steel pipe to 1-1/2" imperial sizes won't there be some confusion?

This happens for multiple sizes between plastic and steel pipes... won't it make metric steel flanges to connect to wrong size imperial flanges? With the size example above if I set 50mm to connect to 1-1/2" for the plastic pipe flanges, will 50mm steel pipe flanges connect to 1-1/2" as well?

Is there a better way to map plastic (HDPE) pipe sizes?
