PVC Pipe

pvc pipeGF 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's product line has grown to include standard and custom extrusions of PVC pipe in schedules 40, 80, and 120; as well as SDR series pipe produced to 13.5, 21, 26 and 41 dimensions.

In addition to a full range of sizes, GF Harvel also offers various options including: belled end, gasketed, roll grooved, and threaded pipe ends, as well as custom dimensions and lengths. 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.
