expectancy of plastic pipe systems far exceeds that of metal systems and
requires simpler and less costly maintenance.
Installation costs are minimized through the use of PVC or CPVC Schedule 80 and
Schedule 40 PVC, since materials are generally lower cost, light weight and
easier to handle. Joining is accomplished through solvent cementing, threading,
flanging or victaulic.
PVC and CPVC Schedule 40 & 80 have an exceptional resistance to a wide range of
chemicals such as most acids, alcohol, alkalis, halogens and many others.
However, chemical resistance is a function of concentration, pressure and
temperature. Please contact us for specific application.
PVC or CPVC Schedule 40 & 80 systems are not adversely affected by environmental
agents or normal soil contaminants.
PVC or CPVC are self-extinguishing and will not support their own combustion in
the absence of ignition source.
Interior walls of plastic piping systems have and remain smooth in virtually any
service. This minimizes head pressure loss through friction. Plastic Piping
systems generally are impervious to scaling or contaminants buildup.
PVC ( Polyvinyl Chloride ) is the most frequently specified of all plastic
piping materials. It has been in use successfully for over 50 years. Of the
various types and grades of PVC used in plastic piping, Type 1, Grade I PVC (
Cell Classification 12454-B ) conforming to ASTM D-1784 is superior. The maximum
service temperature for PVC is 140°F. With a design stress of 2000 PSI, PVC has
the highest long term hydrostatic strength at 73° F. of any of the major
thermoplastics being used for piping.
CPVC ( Chlorinated Polyvinyl Chloride ) Type 4, Grade I CPVC ( Cell
Classification 23477-B ) conforming to ASTM D-1784 has physical properties at
73° F. similar to those of PVC, and its chemical resistance is similar to or
generally better than that of PVC. CPVC, with a design stress of 2000 PSI and
maximum service temperature of 210° F. has, over a period of more than 20 years,
proven to be an excellent piping material for hot corrosive liquids, hot and
cold water distribution and similar applications above the temperature range of
