GF Harvel PVC Industrial Pipe Sch.80


 Application

GF Harvel PVC corrosion resistant pressure pipe, IPS sizes 1/8" through 24", is ideal for use in applications with temperatures up to and including 140°F. Pressure rating (120 psi to 1230 psi) varies with schedule, pipe size, and temperature. It is generally resistant to most acids, bases, salts, aliphatic solutions, oxidants, and halogens. Chemical resistance data is available and should be referenced for proper material selection. GF Harvel PVC pipe exhibits excellent physical properties and flammability characteristics. Typical applications include: chemical processing, plating, high purity applications, potable water systems, water and wastewater treatment, irrigation, agricultural, and other industrial applications involving corrosive fluid transfer.

The pressure ratings given are for water, non-shock, @ 73°F. The following temperature de-rating factors are to be applied to the working pressure ratings (W.P.) listed when operating at elevated temperatures.

Multiply the working pressure rating of the selected pipe at 73°F, by the appropriate de-rating factor to determine the maximum working pressure rating of the pipe at the elevated temperature chosen.

EX: 10" PVC SCH 80 @ 120°F = ?
230 psi x 0.40 = 92 psi max. @ 120°F

THE MAXIMUM SERVICE TEMPERATURE FOR PVC IS 140°F.

Solvent cemented joints should be utilized when working at or near maximum temperatures. GF Harvel does not recommend the use of PVC for threaded connections at temperatures above 110°F; use flanged joints, unions, or roll grooved couplings where disassembly is necessary at elevated temperatures.

Threading of Sch 40 PVC pipe is not a recommended practice due to insufficient wall thickness. Thread only Sch 80 or heavier walls. Threading requires a 50% reduction in pressure rating stated for plain end pipe @73°F.

Chemical resistance data should be referenced for proper material selection and possible de-rating when working with fluids other than water. Refer to GF Harvel 112/401 Product Bulletin for chemical resistance and installation data.

 MATERIAL
GF Harvel Clear™ PVC piping is produced from a rigid, virgin Polyvinyl Chloride (PVC) compound with a Cell Classification of 12454 per ASTM D1784. This material enables GF Harvel Clear piping to safely carry a maximum service temperature of 140°F when appropriate temperature/pressure de-rating factors are applied. In addition to exhibiting desirable physical properties and optimum transparency, this material is listed by the National Sanitation Foundation as being safe for use with potable water (NSF International Standard 61), and also complies with the provisions of Title 21 of the United States FDA Code of Federal Regulations as being safe for use in food contact applications. Due to the non-contaminating nature of GF Harvel Clear PVC piping products, extensive chemical extraction testing has been conducted to evaluate their use in ultra pure applications. Details pertaining to extractable analysis is available from GF Harvel upon request.

GF Harvel Clear™ provides similar reliable chemical resistance properties that conventional PVC piping has demonstrated over the years. In general, it is resistant to most acids, bases, salts and oxidants; detailed chemical resistance data is available and should be referenced for proper material selection.

Since this material is a nonconductor, GF Harvel pipe is not subject to electrolytic or galvanic corrosion.
This material is compatible with conventional PVC pipe, fittings and valves, and can be incorporated into existing PVC systems via the solvent cement joining process. In addition to a full line of Schedule 40 clear fittings for most applications, an endless array of standard PVC components and accessories are readily available. GF Harvel Clear™ PVC exhibits excellent flammability characteristics as well.

Application

 GF Harvel Clear provides several advantages over traditional materials in many applications. It is routinely used as dual-containment piping for high purity piping runs where quick identification of primary tubing and visual leak detection is critical. From semiconductor clean rooms to aggressive chemical processing applications, GF Harvel Clear provides durable leak-free containment piping with optimum visibility.

Compatibility with standard PVC piping systems makes the product ideal for sight gauge assemblies in many applications.

The wide range of sizes and clear fittings available enable custom in-process monitoring of process fluids.

Other applications include:

• Chemical Processing
• Medical/Hospital Use
• Electroplating
• Food Processing
• Dual Containment
• Displays/Exhibits
• Laboratory Applications
• Environmental Applications
• Cosmetics
• Beverage Processing
• Visual Test Equipment
• Fish Hatcheries
• Sight Glass

 

GF Harvel Clear pipe and fittings are manufactured in IPS sizes to Schedule 40 dimensions for optimum performance. This provides sufficient wall thickness for most pressure applications without jeopardizing clarity. As a rigid PVC piping, GF Harvel Clear PVC maintains its integrity in harsh environments. It is suitable for use in both positive and negative pressure applications (i.e., vacuum service).

As with all schedules of thermoplastic pipe, pressure rating is dependent on the pipe diameter selected as well as the operating temperature of the system. As temperatures rise, the pressure rating of the system decreases. Smaller diameter piping can withstand higher pressures than large diameter piping. Refer to the table below for dimensions, tolerances and pressure ratings.
