10.1 General: The Shurjoint grooved piping methods can be selected for joining CPVC pipe in lieu of the solvent cement method at buyer’s option.  Shurjoint CPVC grooved piping method may be used in, but not limited to, plumbing, water distribution systems including potable water, and fire protection systems subject to local code approval and installation in accordance with manufacturer’s installation instructions.

10.2 CPVC Pipe: CPVC pipe shall conform to ASTM F441 – CPVC Schedule 80 and or ASTM F442 – CPVC IPS SDR 13.5.  Acceptable tradenames of CPVC pipe are the FlowGuard Gold®, BlazeMaster® and Corzan® (FGG/BM/CZ™).  Applicable sizes shall be 2” (DN50) through 8” (DN200).  All CPVC fire sprinkler pipe shall be UL listed for wet pipe systems and shall carry a rated working pressure of 175 psi @150°F (1.23 MPa @65°C). 

10.3 Pipe End Preparation: CPVC pipe shall be cut-grooved to AWWA C606.  Roll-grooving is not acceptable. Pipe shall be used as supplied from the manufacturer.  Pipe ends shall be free from indentations, projections, burrs, roll marks, etc. in the area where gaskets are seated.

10.4 Gaskets: Gaskets shall be a pressure responsive design, molded of Grade “E” EPDM, designation 2CA615A25B24F17Z per AWWA C606.  The Grade E gasket shall be used for cold and hot water services for temperatures up to +180^oF (+82^oC), plus a variety of dilute acids, oil free air and many chemical services.  Grade “E” gaskets are not recommended for petroleum oils, mineral oils, solvents, aromatic hydrocarbons and steam services.  Grade “E” gaskets shall be identified with a green color code.  Gasket materials used for potable water systems shall be in compliance with NSF 61. 

10.5 Bolts: Carbon steel track bolts shall conform to ASTM A183 Gr. B, minimum tensile strength 110,000 psi, zinc plated to ASTM B633 with carbon steel heavy duty nuts to ASTM B563 Gr. A.

10.6 Grooved Coupling: The grooved coupling for use with CPVC pipe shall be Shurjoint Model 7705 and Model 7707 flexible couplings.  Housings shall be made of ductile iron per ASTM A536 Gr. 65-45-12.  Acceptable grooved couplings for use with CPVC pipe shall be identified with a tag showing “FGG/BM/CZ™ System Compatible”.  Rigid type couplings shall not be used for CPVC piping.

Section 11: PVC Grooved Piping System

11.1 General: The Shurjoint grooved piping methods can be selected for joining PVC pipe in lieu of the solvent cement method at buyer’s option.  Shurjoint PVC grooved piping method may be used in, but not limited to, plumbing, and water distribution systems including potable water subject to local code approval and installation in accordance with manufacturer’s installation instructions.

11.2 PVC Pipe: PVC pipe shall conform to ASTM D1785 – PVC Schedules 40 and 80 and or ASTM D2241 – PVC IPS SDR-PR.  Applicable sizes shall be 2” (DN50) through 8” (DN200). 

11.3 Pipe End Preparation: PVC pipe shall be roll-grooved to AWWA C606.  Pipe ends shall be free from indentations, projections, burrs, roll marks, etc. in the area where gaskets are seated.

11.4 Gaskets: Gaskets shall be a pressure responsive design, molded of Grade “E” EPDM, designation 2CA615A25B24F17Z per AWWA C606.  The Grade E gasket shall be used for cold and hot water services for temperatures up to +180^oF (+82^oC), plus a variety of dilute acids, oil free air and many chemical services.  Grade “E” gaskets are not recommended for petroleum oils, mineral oils, solvents, aromatic hydrocarbons and steam services.  Grade “E” gaskets shall be identified with a green color code.  Gasket materials used for potable water systems shall be in compliance with NSF 61. 

11.5 Bolts: Carbon steel track bolts shall conform to ASTM A183 Gr. B, minimum tensile strength 110,000 psi, zinc plated to ASTM B633 with carbon steel heavy duty nuts to ASTM B563 Gr. A.
