EN 13480 calculation

[Coalhouse]

question to whomever may be willing and able to help.
Within EN 13480-3 equations 6.1-1 and 6.1-3 for minimum required wall thickness without allowances/tolerances. The equations (6.1-1 or 6.1-3) depends on Do/Di. is Di related to the minimum thickness calculated? Or Di is the chosen wall thickness?

Thank you.

Di = Do - wall thickness

Select a Do and a Di then see what the allowable pressure is.

Depends what the definition says for that equation.

Can you copy in the relevant sections as this isn't a code I'm familiar with.

If you look at e.g. fig. 6.3.2-1 (incorrectly labelled as table), you'll notice D[sub]o[/sub] is the nominal (outer) diameter.

Coalhouse.

In essence you need to do an initial check to determine the wall thickness to see which side of the line you are.

If it's close then do both calcs and take the smallest one.

Do - just take the standard OD of the pipe
