Plastic PVC, CPVC Pipe Applications

Chart gives material characteristics for plastic PVC, CPVC, other pipes commonly found within industrial and residential use within North America.

Material
General Properties
Recommended Use
ABS (Acrylonitrilebutadiene styrene)
Rigid; excellent impact strength at low temperatures; maintains rigidity at higher temperatures. Water, Drain, Waste, Vent, Sewage.
PE (Polyethylene)
Flexible; excellent impact strength; good performance at low temperatures. Water, Gas, Chemical, Irrigation.
PVC (Polyvinylchloride)
Rigid; fire self-extinguishing; high impact and tensile strength. Water, Gas, Sewage, Industrial process, Irrigation.
CPVC (Chlorinated polyvinyl chloride)
Rigid; fire self-extinguishing; high impact and tensile strength. Hot and cold water, Chemical.
PB
(Polybutylene)
Flexible; good performance at high temperatures. Water, Gas, Irrigation.
PP (Polypropylene)
Rigid; very light; high chemical resistance, particularly to sulfur-bearing compounds. Selected Chemical waste and processing.
SR (Styrene rubber plastic)
Rigid; moderate chemical resistance; fair impact strength. Drainage, Septic fields.
