Description
Series 3000 Dielectric Pipe
Fittings and Unions are
durable, corrosion resistant
fittings and unions that consist of a union nut and two
tailpieces. A gasket separates the two tailpieces preventing an electric current
from passing. For flanged
fittings (Models 3100, 3110,
and 3200), a bolt insulator is
required to insulate each
bolt in the flange. Watts
also offers bolt insulators in
a range of sizes.
Dielectric fittings/unions
are designed to install
between pipes made from dissimilar metals. They prevent accelerated corrosion and deterioration in the
piping system due to galvanic and stray current.
Features
•
Designed and manufactured to the highest
quality standards.
•
Unions individually factory certified to withstand a
minimum of 600 volts on a dry line with no
flashover.
ditioners, processing tanks,
steam, gas, and water piping. These fittings/unions
prevent the flow of galvanic
current (an electric current)
and stray current (DC current) passing from one dissimilar metal to another.
Galvanic current accelerates
corrosion in the piping system leading to premature
deterioration of the system.
Stray current produces
extraordinary anodes and
cathodes that can inadvertently enter an alternate (but
unintended) path and create
corrosion in the piping system. Using dielectric fittings/unions prevents this
type of corrosion from occurring.
Note: For applications of gaskets other than specified
above, contact your local authorized Watts representative.
Materials
Dielectric fittings/unions consist of one or more of the
following materials used in accordance with American
Society for Testing and Materials (ASTM):
•
Unions rated to 180°F (82°C) at 250psi (17.2 bar).
•
Flanged fittings rated at 175psi (12.1 bar).
•
Standard Gasket A (GA) suitable for water, air, oil,
natural gas, propane, gasoline, kerosene, mineral oil,
vegetable oil, and alkalines in 180°F (82°C) at 250psi.
Applications
Dielectric fittings/unions are for use in residential, commercial, and industrial applications. Specific applications include the connections of piping of dissimilar
metals on hot water storage tanks, water and air con-
