8 of 31SM-PP 1120 ProPress Systems
C. Press fitting: copper and copper alloy press fittings shall conform to material requirements of ASME B16.18
or ASME B16.22 and performance criteria of ASME B16.51 and IAPMO PS 117 (IAPMO PS 117 is not for
B75). Sealing elements for press fittings shall be EPDM. Sealing elements shall be factory installed or an
alternative supplied by fitting manufacturer. Press ends shall have Smart Connect
®
technology. In ProPress
½" to 4" dimensions, Viega’s unique Smart Connect technology allows identification of an unpressed fitting
during pressure testing. The function of this feature is to provide the installer quick and easy identification of
connections which have not been pressed prior to putting the system into operation.
D. Threaded fittings: pipe threads shall conform to ASME B1.20.1.
E. Hanger standard: hangers and supports shall conform to MSS-SP-58.
2.3 Source Quality Control
A. All fittings in contact with drinking water shall be listed by a third party agency to NSF/ANSI 61 & 372.
B. All fittings used in fire sprinkler applications shall be UL listed.
C. All fittings used in fire sprinkler applications shall be FM approved.
Part 3: Execution
3.1 Examination
A. The installing contractor shall examine the copper tubing and fittings for defects, sand holes, and cracks. There
shall be no defects of the tubing or fittings. Any damaged tubing or fittings shall be rejected.
B. The installing contractor shall insure that sealing elements are properly in place and free from damage. For sizes
2½" to 4", installer should insure that the stainless steel grip ring is in place.
3.2 Preparation
A. Copper tubing shall be cut with a wheeled tubing cutter or approved copper tubing cutting tool. The tubing shall
be cut square to permit proper joining with the fittings.
B. Remove scale, slag, dirt, and debris from inside and outside of tubing and fittings before assembly. The tubing
end shall be wiped clean and dry. The burrs on the tubing shall be reamed with a deburring or reaming tool.
3.3 Installation General Locations
Plans indicate general location and arrangement of piping systems. Identified locations and arrangements are used
to size tubing and calculate friction loss, expansion, pump sizing, and other design considerations. Install piping as
indicated, except where deviations to layout are approved on coordination drawings.
3.4 Installation
A. Pressure rating: install components having a pressure rating equal to or greater than the system operating pressure.
B. Install piping free of sags, bends, and kinks.
C. Change in direction: install fittings for changes in direction and branch connections. Where approved, changes in
direction may also be made by bending of types K and L tube or those with equivalent wall thicknesses.
D. Solder joints: solder joints shall be made in accordance with ASTM B 828. The temperature of the joint during
soldering shall not be raised above the maximum temperature limitation of the flux.
E. Threaded joints: threaded joints shall have pipe joint compound or teflon tape applied to the male threads only.
Tighten joint with a wrench and backup wrench as required.
F. Flared joints: flared copper tube joints shall be made by the appropriate use of cast copper alloy fittings. Flared
ends of copper tube shall be of the 45-degree flare type and shall only be made with a flaring tool designed
specifically for that purpose.
G. Press connections: copper and copper alloy press connections shall be made in accordance with the
manufacturer’s installation instructions. The tubing shall be fully inserted into the fitting and the tubing marked
at the shoulder of the fitting. The fitting alignment shall be checked against the mark on the tubing to assure
the tubing is fully engaged (inserted) in the fitting. The joints shall be pressed using the tool(s) approved by the
manufacturer.
