Piping Systems |
- CONSTRUCTION: CorTech
fiberglass reinforced plastic (FRP) piping and other laminates are manufactured
using polyester and vinylester resins with various types of glass fiber
reinforcements and synthetic surface veil materials. All piping is fabricated
by the contact molding process in accordance with the National Bureau of
Standards Voluntary Product Standard PS-15-69. This type of construction
maintains the highest corrosion resistance of any FRP laminate.
- CHEMICAL RESISTANCE:
CorTech piping systems are fabricated from a large selection of premium grade
resins supplied by the leading manufacturers of these products. Proper resin
system selection will provide service for corrosive material handling at
temperatures up to 250° F. Resin systems are also available for piping to
meet FDA regulations.
- MAINTENANCE: FRP piping
systems are virtually maintenance free as they do not corrode. There is seldom
ever a need for exterior painting or other surface treatment. FRP piping is
normally made without addition of any pigmentation and will appear in the
natural amber/tan coloration, however, if desired, piping may be pigmented for
identification purposes or aesthetics.
- WEIGHT FACTORS: CorTech
FRP piping systems are lightweight, which facilitates easy handling and
installation. Most pipe is available in 10 and 20 foot standard lengths.
- OPERATING PRESSURE:
CorTech pipe and fittings are made to meet pressure requirements up to 150 PSI
with 10:1 safety factor and are suitable for use up to 180° F (82.2°
C) at the designated ratings.
- VACUUM SERVICE: Pipe
and fittings, in sizes 2" through 18" having an internal pressure of
125 PSI are suitable for full vacuum service. Flanges require a 25 PSI rating
for use at full vacuum.
- FLANGE JOINTS: Pipe
systems connected by full face flanges require full face gaskets of medium
durometer (40-70) and should be made of materials having a suitable chemical
resistance.
- BUTT AND STRAP JOINTS:
The most common method of joining pipe and fittings is the butt and strap
welding technique, which provides economy, requires less space and strong
leakproof joints. Butt and strap welding instructions are available upon
request.
- THERMAL EXPANSION:
Since the expansion rate of FRP pipe is several times that of steel,
consideration must be given to accommodate overall linear expansion.

FRP Duct
Systems |
- CONSTRUCTION: CorTech
FRP systems are manufactured of the same materials and construction methods as
that of CorTech FRP Pipe.
- CHEMICAL RESISTANCE:
CorTech FRP Duct is always made of premium grade resins selected for the
particular application of the fumes, vapors and other oxidizing environments
involved. Corrosion use is feasible for continuous operation in the range of
350° F and intermittent service at much higher temperatures.
- FIRE RETARDANCE: Most
resins used in duct fabrication are basically fire retardant without
sacrificing corrosion resistant properties and may take on increased resistance
to fire with the addition of antimony trioxide. Flame spread ratings down to 15
are achievable with the proper selection of materials. (Ref. ASTM E84).
- JOINING METHODS: FRP
Duct is generally assembled and installed using the butt and strap method or
with flanged joints, particularly where the system may require periodic
dismantling for inspection and cleaning. Flanged duct pieces are supplied
undrilled unless specified otherwise.
- PIGMENTATION: CorTech
FRP Duct is normally made without pigment additions and appears as a
translucent amber/tan material unless antimony trioxide is added to the resin
which will change the appearance to an opaque milky tan. Duct may be colored by
the addition of pigmentation and an ultraviolet inhibitor to maintain its
permanence.
- SQUARE DUCT: Square or
rectangular ducting is available on special order. Use of this type of duct is
not recommended unless the application is for an installation where space
limitation precludes the use of the more economical and efficient round
duct.
- PRE-ASSEMBLE
FABRICATION: In addition to supplying standard CorTech Duct components,
complete shop fabricated ventilation systems are available custom made and
assembled with a minimum number of flanges or filed joints for customer
installation at the operation site.
