Detail Info

GF Harvel uses its own custom blend of PVC compound to ensure that desirable physical properties are maintained with every production run. GF Harvel PVC piping exhibits exceptional consistent quality with uniform properties; making it the preferred choice of fabricators and custom houses. GF Harvel PVC pipe is ideal for numerous applications including chemical processing, high purity applications, water and waste water treatment, potable water systems, agricultural, irrigation, plating, and many other industrial applications involving corrosive fluid transfer.


All PVC Schedule 80 pipe shall be manufactured from a Type I, Grade I Polyvinyl Chloride (PVC) compound with a Cell Classification of 12454 per ASTM D1784. The pipe shall be manufactured in strict compliance to ASTM D1785, consistently meeting and/or exceeding the Quality Assurance test requirements of this standard with regard to material, workmanship, burst pressure, flattening, and extrusion quality. The pipe shall be manufactured in the USA, using domestic materials, by an ISO 9001 certified manufacturer. Standard lengths of pipe sizes 6″ and larger shall be beveled each end by the pipe manufacturer. All pipe shall be stored indoors after production at the manufacturing site until shipped from factory. This pipe shall carry the National Sanitation Foundation (NSF) seal of approval for potable water applications. All pipe shall be manufactured by GF Harvel.® PLASTICS, INC


Detail Info

GF Harvel CPVC pipe is produced from a specialty blend of CPVC material with unique physical properties desirable for piping applications (i.e., improved impact resistance and good fire resistance capabilities).

The CPVC product line schedules 80 piping from 1/4″ through 24″ diameters. GF Harvel CPVC piping systems can handle more than three-fourths of the temperature/pressure requirements of today’s typical process plants. CPVC pressure pipe has an upper working temperature limit of 200°F (93°C), or approximately 60°F (15°C) above that of Type I Grade I PVC. As with all thermoplastic piping systems, CPVC’s ability to withstand pressure varies with pipe diameter, wall thickness, and temperature. For pressure piping applications it is recommended for temperatures as high as 200°F (93°C) when appropriate temperature de-rating factors are applied. As the pipe diameter and temperature increases, the pressure rating of the product decreases. For example, 1/2″ Schedule 80 CPVC pipe is engineered for continuous service of 850 psi @ 73°F (23°C). The same pipe in service @ 180°F (82°C) carries a maximum working pressure rating of 210 psi at this temperature. 6″ Schedule 80 CPVC pipe is designed for 270 psi @ 73°F, and 54 psi @ 200°F.
