Free Trial Version of Modern Pipe Stress Analysis Software PASS/START-PROF

The PASS/START-PROF is a pipe stress analysis software that has a long history since 1965, see update history. It is industry standard in several countries for power, process, oil and gas pipelines, and district heating networks, used by 3000+ companies.

The translation into English was carried out only recently, and we are new to the international market. So we invite all engineers to get acquainted with PASS/START-PROF.

To learn what is PASS/START-PROF pipe stress analysis software you may visit the resource center. You will find a webinar recordings, articles and presentations in pdf. Also you may refer to online help system.

Try to work with the program yourself, download the fully functional 30-day trial version from passuite.com/trial!

PASS/START-PROF Installation Steps

Troubleshooting Steps

If you receive the message about problems with internet connection and your company has the proxy, try to enable it in the registration form:

If you didn’t receive the e-mail, check your spam folder. If failed, try to use another e-mail, for example gmail.com. If failed again, then ask developers.

In case of any problem you can ask developers directly using support@passuite.com, using web form or using social media Facebook, Linkedin.

Some of the typical problems with solution are described below.

1Error message #60 “SERVER_PROBABLY_NOT_UP”

It means that PASS/START-PROF can’t reach the license management server (LMS).

Possible reasons and solutions of Error #60:

  • Windows Firewall or corporate firewall or internet provider firewall blocks incoming or outgoing traffic via UDP/6001. Change firewall settings to allow all traffic through UDP/6001
  • You may try to use mobile internet from your cell phone using the wi-fi hot spot to overcome the restrictions and firewall that block the UDP/6001 traffic on your laptop
  • If corporate restrictions can’t be changed, then try to run PASS/START-PROF Trial from the different place (home, work, etc.)

For any other problems that are not described above you may ask developers directly using support@passuite.com, using web form or using social media Facebook, Linkedin.

What to do after installation?

Once the installation is finished you can open the example models and review analysis results as shown below

Follow the video for creating any simple piping model:

Also you can refer “How To” training video series for beginners by clicking here (20 videos):

Or you can create your own simple model. It will not take more than 5-10 minutes from your busy schedule. Watch this tutorial video (from 02:45) for creating the simple U-shaped loop model and thereafter analyzing it.

Also, you can create an underground or buried piping model (underground piping). It will take about 5-10 minutes. Please watch this tutorial video (from 07:25):

Create an HDPE piping model (PE100). It will take about 5-10 minutes. Please refer to this tutorial video:

Also, Create the FRP piping model (Wavistrong 55). It will take about 5-10 minutes. Please watch this tutorial video for help:

If you already have CAESAR II or Autopipe model, you can open it with START-PROF. Autopipe mode should be exported into CII neutral format file. Also, you can open your Caesar II model. Please read this manual (opens in a new tab).
