How does a blind rivet work?
The mandrel is pulled through the body of the rivet using a riveter, or rivet gun.
Closing the handles of the riveter pulls the mandrel head into the body of the rivet with great force, causing the part of the body on the “blind” side of the joint to bulge outwards, effectively locking the rivet in place.
Mandrel Section of a Rivet
The mandrel is a cylindrical rod that is a part of the rivet, used to deform the body of the rivet to create a second head.
The main objective of a pipe bender is to bend the pipe without any buckling (collapsing under pressure), and with as little crimping and flattening as possible. It is important that the pipe keeps its shape as deformed pipes can break under pressure, crack and generally look less appealing.
When using pipe benders, it is also important to use a quality pipe, as cheap piping can often be the cause of crushing rather than the bender itself.
Bending pipe to a decent standard takes a lot of practice and skill – do not expect to be able to create a perfect bend on your first go.
