Insert Shop and Field Welds

The SPOOLER module allows you to insert Shop and Field welds to split up the long or complex piping networks. Field welds can be used to cut a pipe into shorter lengths or break up a network where there are no convenient joints, these welds will be made at the erection site. Shop welds can be used to separate parts or assemblies that need to be fabricated and tested before being attached to other parts of the spool. Welds can be inserted to break a piping network at a p-point of a particular component or at some defined point along a length of a pipe.

If a component needs to be tested in the fabrication shop before shipping and then connected to pipes and other components at the erection site. You will need to insert Field welds., where possible, welds should be inserted at a p-point (Design Point) of a welded component, because the component is attached to the pipe by a weld anyway, so it is not creating any extra work just moving the location for the work from the Fabrication Shop to the Erection Site.

Select Create > Weld, from the main menu bar to display the Create Weld window:

The Create Weld window is a dual purpose window, which allows you to insert a weld at a design point or at a position in the tube (pipe).

Insert a Weld at a Design Point

By default the Create Weld window is displayed with Design selected in the At drop-down list.

In the Type drop-down list select Field or Shop.

In the Allowance box, input the fitting allowance.

Click Apply, you are prompted to Pick a Design Point for WELD.

Once the selection has been identified, the software will then automatically select the required weld in the current specification. If there is a choice and the specification does not have a default, the CHOOSE window is displayed populated with these choices.

After selecting the type of weld to use, you must click OK to insert the weld or CANCEL to discard any selection and close the CHOOSE window.

Once the selection has been made, the weld is inserted at the design point and the weld is displayed in the design hierarchy as a welded element.

Split a Tube with a Weld

To insert a weld at a position in tube (pipe), change the At drop-down list from Design Point to In Tube, the Create Weld window is displayed:

In the Type drop-down list select Field or Shop.

In the Distance box, enter the distance along the pipe to insert the weld.

In the drop-down list, select From Previous, In Front of Item or Behind Item:

• Click From Previous - Inserts the weld the specified distance from a reference element (selected by you).

• Click In Front of item - Inserts the weld the specified distance in front of the reference element (selected by you).

• Click Behind Item - Inserts the weld the specified distance behind the reference element (selected by you).

In the Allowance box, input the fitting allowance.

Click Apply, you are prompted to Pick a position in tube for WELD, after making the selection you are prompted to Pick an element for WELD distance. After the selection the weld is inserted into the tube at the specified distance from the element.

Click Dismiss to discard any inputs and close the Create Weld window.
