Hanger Types

Pipe Stress Interface - R2 User Guide

The UDAs: USTHTYP and USTSCHTYP contain hanger construction description abbreviations. The UDA: USTHTYP describes the design-engineering. The UDA: USTSCHTYP describes the calculated mode of operation at the hanger point.

The UDA: USTHTYP is used to define a pre-selection for hanger design. The pre-selection is used in the Cascade software, owned by Witzenmann GmbH, Pforzheim (Germany). For example, the UDA value KH defines a constant hanger.

The following table displays Rohr2 definitions with no corresponding Witzenmann hanger type (none). In such cases, the definition must be produced in the Cascade software.

The table provides an overview of the most common hanger types.
