Plastic caps with corrosion
inhibitors protect pipe in transit
The CorroLogic CorrPlug caps
(photo) protect pipe ends, pipe
threads and other tubular objects
from corrosion, mechanical damage
and intrusion (by foreign objects) during
storage and shipping. These pipe
caps are constructed from heavywall
black polyethylene that contains
proprietary, vapor-phase corrosion
inhibitors. They are designed for
easy installation and removal, which
helps to reduce labor needs. During
humidity testing, pipe threads
equipped with these caps showed
a significant advantage in corrosion
resistance compared to those
capped with regular plastic caps
that contain no corrosion inhibitors,
says the company. These caps are
made to order in most standard NPT
pipe sizes, ranging from 0.25 to 65
in. in dia. They protect carbon steel,
stainless steel, copper, brass and
aluminum pipes. - Cortec Corp.,

These pipe and tube
couplings are self-aligning
The Tuf-Lok ring-grip pipe couplings
(photo) are heavy-duty, self-aligning
couplings that are suitable for either
high-pressure (to 150 psig) or full
vacuum-rated applications. These
couplings install quickly and easily,
reducing installation costs. They are
available in 2-in. dia. (50-mm) through
10-in. dia. (250-mm) pipe sizes. They
are made for use on plain-end pipes,
regardless of pipe wall thickness. No
machining or grooving is required to
maintain pipe integrity. They are designed
to be self-grounding, vibration-resistant
and leak-proof. Numerous
gasket materials are available to
help operators meet desired design
conditions for food-grade, highertemperature
and special chemicalresistant
applications. They install
easily, making them ideal for situations
that require frequent assembly

These piping components
withstand harsh chemicals
The ChlorFIT piping system (photo),
made from Schedule 80 chlorinated
polyvinyl chloride (CPVC), is designed
to provide a long-lasting, cost-effective
alternative to copper and stainless-steel
piping for applications that require transport
of corrosive fluids. This helps to
reduce maintenance and replacement
costs, compared to traditional installations,
says the company. The pipes and
fittings are extruded or molded from
premium-grade CPVC compound,
which has proven resistance to nitric
acid, sodium chloride, sulfuric acid,
phosphoric acid and hydrochloric acid,
as well as many other corrosive fluids.
This material also has superior fireresistant
qualities, and holds the ICCES
PMG E84 25/50 plenum fire rating.
Unlike many other thermoplastic piping
options, ChlorFIT can operate at temperatures
from 32-200°F (higher than
many other plastic piping systems), and
is more lightweight and easier to handle
than metal piping solutions. Pipes are
available in sizes from 0.25 to 24 in. dia.,
and joining is accomplished with solvent
welding, threaded joints and full-pressure
flanges. - GF Piping Systems,

These tubes and fittings meet
rigorous high-purity needs
This company's comprehensive family
of DIN tubes and fittings (photo) is
specifically designed for food, dairy,
beverage, personal care, biotechnology
and pharmaceutical applications.
All products are designed to have
crevice-free interiors and secure, selfaligning
joints, and they meet ISO
9001 (quality) and ISO 14001 (environmental)
standards. The product
family includes unions, clamp fittings,
flanges, bends, tees, reducers and
tubes that reduce corrosion resis
