IM-PP 599834 0320 ProPress Stainless
Viega ProPress Stainless ttings exposed to corrosive action, such as
soil conditions or moisture, must be protected in an approved manner in
accordance with NFPA 54 Section 404.8, NACE Standard RP0169-2002
Section 5, 2009 UPC Chapter 6 Section 609.3.1, 2009 UMC Chapter
13 Section 1312.1.3, or satisfying local code requirements. In addition,
systems should be properly sized to minimize the risk of erosion corrosion
resulting from excessive velocities.
■ Stainless steel should not be directly connected to copper. Brass or
bronze ttings are a suitable transition in most applications.
■ ProPress Stainless dielectric unions should be used when connecting
stainless steel to steel or galvanized steel pipe. Do not use dielectric
unions intended for copper to steel transitions to connect stainless
steel to copper or steel.
■ Care should be taken to select hangers of suitable material that are
galvanically compatible with the tubing.
Above ground tube and ttings do not normally require external corrosion
protection.
Please contact the Viega Technical Services Department for questions on
this subject.
■ Pressure surges or transients from fast-acting valves, pump surges,
and other sources that result in water hammer may cause damage to
many system components, including press ttings.
■ When fast-acting valves and/or pumps are incorporated into a system,
the designer and installer should isolate press ttings from sharp
pressure surges.
■ ProPress Stainless ttings should be isolated or
separated by sucient distance from pumps, fast-
acting valves, and other sources of pressure transients.
■ The maximum operating pressure in a ProPress Stainless
system is 200 psi, which applies to general operation as
well as pressure transients.
■ Good engineering practices should be used to design the
system in a way that minimizes sharp pressure surges.
2.5.6 Concealed Spaces
2.5.7 Corrosion Protection
The Viega ProPress Stainless tting system has been approved for use
in concealed spaces. Specic performance tests were conducted to
evaluate the ttings for use in concealed spaces. Concealed tubing and
ttings shall be protected from puncture threats.
