Re: How to set smaller gap values?

Hello, The gaps less than 5 mm are not recommended to be taken into account during stress analysis. It is just a technological gap that may actually be absent. The accuracy of such a gap cannot be ensured during installation. START-PROF ignore gaps less than 5 mm in standard guide supports . But if ...

A question about a pipe between the two anchors

A question. The correct answer will be posted later in comments. More information about pipe stress analysis here: https://passuite.com/start#resources-tab You have a pipe restrained between two anchors. Thermal expansion is zero. Internal pressure is high. The axial force will be (explain why): 1) ...

Re: ASME welding tee insertion

The length, height, crotch radius are mostly needed for EN and GOST tees. The tee can be the same pressure rating as the connected pipe and have greater wall thickness or it can be lower pressure rating but have the same wall thickness. If you are using the first option, you can specify the tee leng...

Re: Faster flanged valve insertion

First way:

Add nodes on the valve ends

the second way is just to specify the valve length and weight including all 4 flanges. It is simpler
