- Bell end
-
a pipe with an expanded end that serves as a socket for the next pipe. Care is required when joining bell end pipe so as not to “burn” the inside.
- Blue Glue
-
Typically our 222, although could be another's blue colored irrigation, pool or spa solvent cement product. These are not glues, but the name “sticks”.
- Burr
-
A rough edge or area remaining on material, such as metal, after it has been cast, cut, or drilled - shavings.
- Cure
-
the process of the solvents migrating and evaporating from the joint. This can take an hour to days.
- Dauber
-
The typical applicator for solvent cements. Made of wire and a ball of polyester. Good for small pipe sizes.
- Gelled
-
Cement gone bad by becoming so thick it no longer flows. Can happen for many reasons.
- Hot
-
Typically means active or quick solvent cement - likely because aggressive cements will “melt” small and thin wall pipes. Hot cements contain more THF as a basic rule.
- Interference fit
-
Plastic pipe fittings are often smaller in diameter than the pipe itself. This creates and interference fit needed for a good solvent welded joint.
- Schedule
-
a certain design set for pipe and fittings (Sch. 40 or 80 for eg.)
- Set
-
When the fitting takes a set - it is no longer able to move, push off or be
twisted by hand - this happens quickly, typically a few seconds to a few min.
- Snake(d)
-
properly installed long runs of plastic pipe need to be placed underground with expansion and contraction room as plastic pipe dimensions change with the weather. This undulating shape can resemble a snake.
- Viscosity
-
Liquid “thickness” resistance of a liquid to sheer forces (and hence to flow)
