Materials and Their Characteristics # 1985 York
CPVC piping systems have found wide use in many market segments due to its ability to meet a wide range of temperatures and pressure needs as well as excellent chemical resistance.
Thermoplastic piping systems are capable of being the most cost effective solution to the problem of transporting corrosive fluids. Selection of the correct thermoplastic for a specific application is not always clearcut due to the diverse natures of corrosion problems. Without the specific knowledge of newer thermoplastics capability and availability it is possible to overlook a candidate material.
Polyvinyl chloride (PVC), one widely used thermoplastic for corrosive service, is limited to a temperature of approximately 60°C in piping applications. On the otherhand chlorinated polyvinyl chloride can provide the consumer temperature service up to 100°c.
BFGoodrich commercialized CPVC in 1960 to fillthe market need for a versatile polymer like PVC with superior heat resistance and elevated temperature/pressure performance. Since 1960 CPVC has gained acceptance in a diverse number of piping applications that include water and waste treatment, chemical processing pipe, electroplating, metal finishing, wood, pulp and paper manufacture, fertilizer production and domestic hot water distribution systems.
Pipe sizes and components have grown with the market. Today, CPVC pipe and fittings are available through 250 mm. A gamut of CPVC valves - ball, butterfly, check, diaphragm, gate and needle are available as well as CPVC centrifuged pumps, drum pumps.
Although CPVC piping systems are typically joined by solvent cement socket joints, threaded joints, flanges and mechanical couplings can be used when recommended by the manufacturer.
