MTO provides an alternate gasket search for the situation when end A of a bolted joint differs from end B. Although you can achieve the same results with an optional gasket, this approach allows the selection to be made by the reference data. Therefore, no input is required from the designer to report the correct gasket by MTO.

  • End A connected to end A reports gasket X

  • End B connected to end B reports gasket Y

  • End A connected to end B reports gasket Z

where end implies a combination of end preparation, table suffix, and pressure rating.

In order for the alternate gasket search to take place, the following steps must be done:

  • Set the Gasket Search toggle to Alternate on the Material Takeoff Options form in Project Administrator.

  • Modify PCD as follows:

The system performs the following actions to determine the gasket data to report.

  • MTO collects the end preparation, pressure rating, and table suffix for both mating bolted ends.

    • If both sets of data are the same, MTO searches the spec for the gasket in the standard manner.

    • If any of this data is different, MTO searches the spec using both green and red data.

This method requires that the gasket data be created in the spec with some precedence for the green and red data to eliminate any order dependencies. For example, the precedence could be:

  • If ratings differ, green data would contain the higher rating (and the corresponding end preparation and table suffix), or

  • If end preparations differ, green data would contain the lower end preparation value (and the corresponding pressure rating and table suffix), or

  • If table suffix values differ, green data would contain the lower table suffix (and the corresponding pressure rating and end preparation).
