How to Connect Tubing-Cross
and Tee Joints
T E E J O I N T S
Welded joint used for connecting tubes at any angle.
1 rn Perpendicular member is shaped to fit mating tube.
Gusset plate makes a reinforced tubing connection. At-
tachment can be made by means of a weld, rivets or bolts.
Formed flanges simplifies tubing connection. Attachment
6 Threaded welding studs make a convenient connection.
- Welding stud to a pad on tubing reinforces joint,
5. can be made by using threads or welding operation.
Expansion sleeve can be used to join tubes. Split-sleeve
is expanded in tubink holes by means of steel drive plug. 2 Curved tubing used as a cross joint; this can easily be
connecttd by projection welding.
Projection welding parallel tubes makes more rigid con-
3. struction. Air vent tubes can be attached in this way.
Simple guide for other tubing or shafts can be made by
4. projection welding ring to tubing.

3 Bolted connection is used for racks and frames. Requires
a threaded insert and notching the end of joining tube.
Tubing 8t Pipe Connections
Tubes of different sizes can be more rigidly connected by
inserting the smaller tube inside the larger one.
Reinforced connection can be made by attaching pads to outside or inside surface. Flattened tubing simplifies the connection
7. for brazing or projection welding. Pads may be threaded either for pipe or screw fitting.
Flattened tubing makes joint when tubes intersect in same
5. plane. Connection is welded, riveted or bolted
