Connect Ducts/Pipes

Used to quickly join common duct or pipe intersections; Turns, tees and cross intersections. Depending on the circumstances, individual fittings or a combination of fittings are inserted using Mechanical discipline's auto fitting placement functionality.

Improved capabilities:-

Integrated and simplified the existing functions of connect Ducts/Pipes and HAVC(Plumbing) Autofitting Preferences to improve the work efficiency of users.

You don't need to Select the fittings you want to use and set its parameters in Autofitting Preference. You can select most used fittings in connect Ducts/Pipes tool itself.

SettingDescription
Ducts
  • Row1 represents the type of connection.
  • Row 2 represents an additional step on interface-confirmation of the shape of duct. (Rectangular/Round/oval)
  • Row 3 is the specific fittings under each group, and users will choose the fitting according to their needs.
  • Next is Preview .The number 1 2 3 in the preview window represents the place order of each fitting, by which users can easily know how to place the fitting and tell which point need to be placed first.
Methods available for joining duct intersections.
  • Elbow - Joins ducts with an elbow fitting for any angle, or an elbow/transition fitting combination if the joined components differ in size or shape.
  • Takeoff - Joins ducts with a takeoff fitting for any angle, or a takeoff/transition fitting combination if the joined components differ in size or shape. The first duct selected is broken, and is then attached to the second duct.
  • Double Takeoff - Joins crossing duct intersections with two takeoffs for any angle, or takeoff/transition fitting combinations if the joined components differ in size or shape. The first duct selected is broken, and the broken segments are then attached to the second duct.
  • Tap - Joins ducts with a tap fitting for any angle, or a tap/transition fitting combination if the joined components differ in size or shape.
  • Tee - Joins perpendicular ducts with a tee fitting, or a tee/transition fitting combination if the joined components differ in size or shape. The first duct selected is broken, and is then attached to the second duct.
  • Cross - Joins perpendicular duct intersections with a cross fitting, or a cross/transition fitting combination if the joined components differ in size or shape.
  • Ogee - Joins only aligned rectangular duct at different elevations with an ogee fitting.
  • Wye- Joins ducts with a wye fitting for angles of 45° and 90°. All the three ducts are selected, and then attached.
Tip: Use (HVAC Autofitting Preferences) to change the ogee sheet size auto-fitting preference.
Pipes
  • Row 1 represents the type of connection, using a bend, a Tee (Wye) or a cross to connect the pipes.
  • Row 2 is the specific fittings under each group, and users will choose the fitting according to their needs.
  • Row 3 is a preview window, from which users can see which specific fitting they are choosing to be used. The number 1 2 3 in the preview window represents the place order of each fitting, by which users can easily know how to place the fitting and tell which point need to be placed first.
Methods available for joining pipe intersections.
  • Elbow - Joins pipes with an elbow fitting for any angle, or an elbow/transition fitting combination if the joined components differ in size or shape.
  • Tee - Joins perpendicular and angled pipe intersections with a tee fitting. The first pipe selected is broken, and is then attached to the second pipe. Tees are automatically selected from available manufacturer catalogs.
  • Cross - Joins perpendicular pipe intersections with a cross fitting, or a cross/transition fitting combination if the joined components differ in size or shape.
  • Wye - Joins pipe intersections at standard angles of 30°, 45° and 60° with a wye fitting.

Confirmation of the Shape of Duct

1] Rectangular-Shape Fitting
  • Join with Elbow- The tool applies to rectangular shape ducts and also accepts ducts of different sizes. After accepting the selection of the main duct, followed by each branch, the ducts are then joined once you accept the selections. The properties of selected elbow applies to the fitting.
  • 2 Point to Place: Duct Fitting|Rectangular-Elbow|Mitered -In Rectangular-Elbow|Mitered 2 points are to be placed inorder to connect the ducts.
  • Join with Cross -The tool applies to rectangular shape ducts and also accepts ducts of different sizes. After accepting the selection of the main duct, followed by connection 2 opposite to it and branches at each side, the ducts are then joined once you accept the selections.
  • 2 Point to Place: Duct Fitting|Rectangular-Square Throat Cross -In Rectangular-Square Throat Cross 2 points are to be placed inorder to connect the ducts.
  • 4 Point to Place: Duct Fitting|Radius Throat Square Heel Cross -In Radius Throat Square Heel Cross 4 points are to be placed inorder to connect the ducts.
  • Join with Tee - The tool applies to rectangular shape ducts and also accepts ducts of different sizes. After accepting the selection of the main duct, followed by each branch, the ducts are then joined once you accept the selections. The properties of selected tee applies to the fitting.
  • 2 Point to Place: Duct Fitting| Square Throat Tee -In Square Throat Tee 2 points are to be placed inorder to connect the ducts.
2] Round-Shape Fitting
  • Join with Tee- The tool applies to round shape ducts and also accepts ducts of different sizes. After accepting the selection of the main duct, followed by each branch, the ducts are then joined once you accept the selections. The properties of selected tee applies to the fitting.
  • 3 Point to Place: Duct Fitting|Round Tee|Round Tee -In Round Tee 3 points are to be placed inorder to connect the ducts.
  • Join with Wye- The tool applies to round shape ducts and also accepts ducts of different sizes. After accepting the selection of the main duct, followed by each branch, the ducts are then joined once you accept the selections. The properties of selected wye applies to the fitting.
  • 3 Point to PlaceDuct Fitting|Drop Cheek Wye -In Drop Cheek Wye 3 points are to be placed inorder to connect the ducts.
  • Join with Elbow- The tool applies to pipes and also accepts pipes of different sizes. After accepting the selection of the main pipe, followed by each branch, the pipes are then joined once you accept the selections. The properties of selected elbow applies to the fitting.
  • Pipe Fitting|Elbow|Default Elbow -In Elbow Pipe Fitting the first pipe is selected followed by the second pipe inorder to connect the pipes.
  • Join with Tee- The tool applies to pipes and also accepts pipes of different sizes. After accepting the selection of the main pipe, followed by each branch, the pipes are then joined once you accept the selections. The properties of selected tee applies to the fitting.
  • Pipe Fitting|Twin Elbow|Twin Elbow -In Twin Elbow Pipe Fitting the first pipe is selected followed by the second pipe inorder to connect the pipes.
  • Join with Cross- The tool applies to pipes and also accepts pipes of different sizes. After accepting the selection of the main pipe, followed by each branch, the pipes are then joined once you accept the selections. The properties of selected cross applies to the fitting.
