Tee Fabrication Flashcards
Formula for stretch out
What is a stretch out
Diameter times pi or D×3.14
The length of the stub pattern
Formula for small end S.E.
-7MT minus seven times metal thickness
What does a bead do on a pipe
What machine is used
A stopping point and strengthening
Bead roller
What is the elevation view
Looking at the “front view” or side view.
Usually L.S.V or R.S.V
What is the plan view
The drawing that shows the opening of the stub, top down view “birds eye”
How is the small end identified
A notch in corner
What is a crimp used for, does it shrink metal
Aid in joining pipe, doesn’t shrink metal
A line used to divide an object into sections when developing patterns for round or irregular shapes, drawn on the elevation view at their true length-
Element lines
Machine used to form flange
Burring machine
2 ways to stretch/shape flange
Riveting hammer/ flattening rolls
3 methods of attaching pipe stub
Pop rivets, solid rivets, and spot welds
Why do we not put fasteners in the small end of a pipe
The faster will interfere with the fitment
How many views are required to draw a mitre line
2, Elevation view LSV and end view
Why is it a good idea to start spot welding at the center of a lap seam
To avoid bulging and buckling
The 3 methods used to divide a stretchout into 12 equal spaces?
Sloped rule, dividers, mathematical
