Why Should I Use Hot and Cold Clash Detection?
The following video presents a closer look at the benefits of using AutoPIPE for "hot" and "cold" clash detection with 3D CAD Plant models.

Lets take a look at how information mobility can help with finding 3D Hot Piping interferences during the design process which is much better and safer than finding problems during Plant operation.
Piping clashes with other pipes, structures, equipment, and/or HVAC are not uncommon and can be very costly to re-design and worse-case scenario that Plants have to be shutdown for failure investigation and repairs.
Clashes are everywhere... Even under our Cars as can be seen with this hot exhaust pipe hitting the chassis.
Hot Clashes are typically caused by pipes heating up and moving, but large pipe movements can also easily occur with extreme loads like wind or earthquakes.
Pipeline explosions do happen and are expensive! Like the $12billion Deep Water Horizon Offshore Oil Rig in the Gulf of Mexico in 2010.
Now with AutoPIPE, you can analyze any type of loading condition applied to piping and structures. And With Bentley Navigator or OpenPlant Modeler, you can quickly evaluate accurate soft and hard clashes against Structure, Electrical, and Equipment.
But the 3D Plant model may be designed in PDS or PDMS or Plant 3D or SmartPlant and can still be viewed in Bentley Navigator or MicroStation.

The problem is how to identify all the 3D Clashes between Piping, Steelwork, Equipment and Electrical when we have a maze of piping as shown here”. And what about when the piping moves under Temperature, Seismic or extreme loading”, The structural moves under its own seismic and live loading. “For example, How can we easily check 3500 pages of Pipestress displacement data for 241 different Loadcases and locate these movements in Plant model?
And How long is that going to take?
Running the new AutoPIPE Hot clash detection – they generated a hot deflected DGN pipestress model (Red) and referenced into the PlantSpace 3D model (yellow) … 3 critical hot clashes were quickly discovered which avoided 3 costly operational failures which they did not discover using traditional manual methods.
