GF Harvel - FlowGuard Gold CTS Plumbing Pipe

Major building codes have approved the use of CPVC piping as an acceptable material for plumbing systems, provided that the piping conforms to applicable industry standards and has been listed by a third party for conformance to NSF Standard 14 and /or NSF Standard 61 requirements. Code bodies that accept the use of CPVC include BOCA National Plumbing Code, National Standard Plumbing Code, SBCCI Standard Plumbing Code, International Plumbing Code, and the Uniform Plumbing Code to name a few. The user should determine approval and installation requirements from the local code having jurisdiction prior to use.

GF Harvel® FlowGuard Gold® CTS CPVC hot and cold water plumbing pipe is manufactured in strict compliance with ASTM D2846. This standard defines requirements for materials, workmanship, dimensions, tolerances, pressure-bearing capability, and thermocycling resistance. GF Harvel® FlowGuard Gold® plumbing pipe is manufactured to SDR 11 specifications in accordance with this standard. With SDR series pipe, the outside-diameter-to-wall- thickness ratio is constant regardless of pipe diameter; therefore all sizes of pipe carry the same pressure rating.

All CPVC SDR 11 Series hot and cold water plumbing pipe shall be manufactured from a Type IV, Grade I Chlorinated Polyvinyl Chloride (CPVC) compound with a Cell Classification of 24448 (CPVC4120) per ASTM D1784. The pipe shall be manufactured in strict compliance to ASTM D2846, consistently meeting and/or exceeding the quality assurance test requirements of this standard with regard to pressure rating, material, workmanship, burst pressure, flattening resistance, and extrusion quality. The pipe shall be manufactured in the USA by an ISO 9001 certified manufacturer. All pipe shall be packaged on-line immediately after its manufacture and 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. The pipe shall have a flame spread rating <25 and a smoke development rating <50 when tested and listed for surface burning characteristics in accordance with ULC-S102.2 or equivalent; this information shall be printed on the pipe along with the mark of the listing agency. This pipe shall also meet the requirements of CSA B137.6 for CPVC hot and cold water distribution piping. All pipe shall be manufactured by GF Harvel., Inc, trade name GF Harvel® FlowGuard Gold® CTS CPVC.

Once the system has been installed and allowed to cure properly the system shall be tested in accordance with applicable code requirements. When testing with water (hydrostatic testing), the system must be slowly filled with water and the air bled from the highest and furthest points in the system before test pressure is applied. Air must be removed from piping systems to prevent it from being locked in the system when pressure is applied. Failure to do so could be harmful to jobsite personnel should a failure occur. If a leak is found, the affected product must be cut out and discarded. A new section can be installed using couplings or other approved means.

Based on large scale testing, GF Harvel® FlowGuard Gold® is also listed for surface burning characteristics by ULC having a low flame spread rating (<25) and a low smoke development rating (<50) validating the excellent fire performance properties of the piping. This listing can be used to validate that GF Harvel® FlowGuard Gold can be installed within return air plenums based on its excellent fire performance properties. GF Harvel® FlowGuard Gold also meets CSA B137.6 Chlorinated Polyvinyl Chloride (CPVC) pipe, tubing and fittings for hot and cold water distri-bution systems – this information, along with ULC flame and smoke information is printed on the pipe for easy identification in the field.
