Automet® FAB - Design Input: Pipe Connections

There are many types of pipe connections - those available in automet are listed below. The weldolet pipe connection is the default and can be changed by the user as needed.

Because pipe specifications can change at a connection, the pipe schedule can also be adjusted which is common with small-diameter connectors. If you are unsure, use the default, standard schedule (STD).

When creating a fitting to fitting where the schedule is set to match the drawing, the branch length should correspond with the drawing length. To get this, the user can adjust the specification of the branch flange.

Pipe connections can be rolled or offset. The distinction between these two is that the flange face remains on the grid when offset. When rolled, the flange remains square to the fitting but is not on the grid line.

This video automet® FAB - Design Input - Pipe Connections shows how to enter each of the below pipe connections in automet FAB.

Stab-in

A stab-in is a branch connection that does not have a fitting. A pipe-saddle profile links the branch pipe to the line pipe. Stab-ins, like all pipe connections, can have offset geometry if required.

Supports

When creating supports on pipes such as shoes and trunnions, pipe connections (PC) are used. See our video on entering these into the system here.

• 

The support can be in several forms: plate, box or cylinder.

Cylinders allow you to choose the specification of the pipe.

Offsets

This is an offset pipe connection. The weldolet is offset 20 mm south of the pipe's centre line. The image shows the rectangular and the polar settings.

Rolls

Below is a pipe connection with a roll. The weldolet is rolled 20 mm south of the pipe's centre line, which means the connector revolves around the pipe at an angle of 7.55°. The image shows both the rectangular and the polar coordinates. By using the polar/rectangular button, the values can be entered in mm as grid offsets (rectangular) or as a bearing and a distance (polar). Other pipe connectors, like latrolets and weldoflanges are fittings with lengths established by the database. The exceptions are stab-ins, trunnions and shoes.
