LESSON 3 BRANCH CONNECTIONS
This Lesson covers the placement of branch components, such as: olets, base elbow supports, etc.
AutoPLANT provides a Tap Ports command that must be executed to designate the component, and the location on the component where the branch component will be placed. A top port must be defined before placing the following component types:
• Olets: To place an olet, you must first place a tap port to designate the component on which the olet will be placed. For example, to attach a weldolet to a pipe, you first designate the tap port location.
• Elbolets: To place an elbolet, you must first place a tap port at the center port of an elbow.
• Base Elbow Supports: To place a base elbow support, you must first place a tap port at the center port of an elbow.
• Stub-in branches: To place a stub-in, you must first place a tap port and then place a pipe entity attached to a tapped port on another pipe segment.
Objectives
The objectives of this Lesson are as follows:
• Learn how to define a Tap Port to route a bypass line
• Learn how to place pipe for base support
• Learn how to place an elbolet for base support
Exercise 1 Defining a Tap Port to Route a Bypass Line
In this exercise, you will define a tap port on the vertical pipe segment in Line 1001, upstream from the gate valve, then placed a weldolet and route a 3” {80mm} bypass line as shown below.
1. Select Branching Components > Olets > Tap Port from the Piping menu.
Respond to the prompts as follows to define the tap port.
Pick component to be tapped
Select the base port
Toggle/<Enter to select currently highlighted port>:
If the port at the bottom of the pipe is selected, press Enter to accept that port. Otherwise, type T and press Enter until the bottom port is selected. Press Enter when the bottom port is highlighted to accept the selection.
Toggle base port/Align/change Ref point/<Enter Distance>:
Type 2’-6” {750} and press Enter to specify the tap port location that distance from the bottom pipe port.
The Tap Port Size dialog displays to enable you to define the size.
Select 8” {200} and press OK.
Enter orientation of tap port
Select –Y from the directional aids toolbar to designate an orientation in the horizontal plane.
2. Now that the tap port is defined, you can place the weldolet. Select Branching Components > Olets > Weldolet from the Piping menu. Respond to the prompts as follows to place the weldolet:
Current Elevation/<BOP 115’>
Relative/create taP/Elev/<Pick point or Return for fit-fit>:
Pick the pipe on which the tap port was just defined. PIPING will recognize the previously defined tap port and highlight it.
Relative/create taP/Elev/<Pick point or Return to fit-fit>:
Press Enter to accept the highlighted port.
The Specification Selection dialog displays.
Select the 8x4 {200x100} weldolet and press OK to place the fitting.
3. Connect an elbow to the weldolet with its branch in the negative-X direction, then connect a flange, gate valve (no topworks), and another flange.
4. Create another tap port, in the vertical run of line L1002, aligned with the branch on L1001 as shown above. Place a 8x4 {200x100} weldolet at the tap port location. Attach an elbow in the +X direction, then place connecting pipe between the elbow and flange to complete the bypass line as shown above. Select the Pipe Components > Pipe command and respond to the following prompts:
Current Elevation/<BOP 115’>
Relative/create taP/Elev/<Pick point or Return for fit-fit>
Press Enter to accept the highlighted port Connect to/<Enter Length>:
