Automet® FAB - Design Input: Pipe Connections
Overview
A variety of pipe connection types are available in automet® FAB. The weldolet pipe connection serves as the default option and can be modified as needed.
Because piping specifications can change at a connection point, the pipe schedule can also be adjusted (commonly required with small-diameter connectors). If you are unsure of the schedule, use the default standard schedule (STD).
When creating a fitting-to-fitting connection where the schedule matches the drawing, the branch length must correspond with the drawing dimension. To achieve this, adjust the specification of the branch flange.
Pipe connections can be rolled or offset:
- Offset: The flange face remains aligned with the grid lines.
- Rolled: The flange remains square to the fitting, but is rotated off the main grid.
Weldolets
Weldolets are the default pipe connection type in automet® FAB.
Stab-Ins
A stab-in is a branch connection without an explicit branch fitting. A pipe-saddle profile links the branch pipe directly to the main line pipe. Stab-ins can incorporate offset geometry if required.
Supports
Pipe connections (PC) are used when adding pipe supports such as shoes and trunnions.
Supports can be created in several physical geometries, including plate, box, or cylinder forms.
Selecting a cylinder support allows you to choose the exact pipe specification for the support legs.
Offsets
In an offset pipe connection, the connector is shifted parallel to the pipe centre-line. In the example below, a weldolet is offset 20 mm south of the main pipe centre-line.
Rolls
In a rolled pipe connection, the connector revolves around the outer diameter of the pipe. Below, a weldolet is rolled 20 mm south of the pipe centre-line, resulting in a rotation angle of 7.55°.
Coordinates can be entered in millimetres as grid offsets (rectangular) or as a bearing and distance (polar) using the polar/rectangular toggle button. Most pipe connectors (such as latrolets and weldoflanges) have fixed fitting lengths defined by the component database, with the exception of stab-ins, trunnions, and shoes.
