convoluted heavy-duty molded PTFE bellows
The PROCO Series 4400 PTFE Molded Bellows Expansion Joints are used for
corrosive applications found in: Chemical-Petrochemical, Industrial Process Pip-
ing Systems, Power Generating Plants, Pulp/Paper Plants, Water/Wastewater
Sewage and Pollution Control Systems where metallic joints/lap joints of PTFE
& FEP-lined rubber expansion joints may have been previously used or speci-
fied. Specify PROCO Series 4400 Expansion Joints for installation between an-
chor points or next to mechanical equipment such as: Absorption Machines,
Blowers, Chillers, Compressors, Fans, Graphite Heat Exchangers, Glass Lined
Vessels, Pumps, and Exotic Alloy/Glass Lined Piping Systems. The Series 4400
Expansion Joints are designed to: (1) Absorb Pipe Movements/Stress, (2) Re-
duce System Noise, (3) Reduce Mechanical Vibration, (4) Compensate Align-
ment/Offset, (5) Eliminate Electrolysis, (6) Protect Against Start-up/Surge Forces.
Our history in the manufacture of expansion joint products dates back to 1930.
When an engineered solution is needed to solve a piping problem, call PROCO.
Engineered For Your Application. The PROCO Series 4400 PTFE Expansion Joints
are hot formed from a PTFE tube made with a tape wrapping process. The tube is
processed so that the PTFE has a low level of crystallinity, which translates into an
improved service life. The seamless PTFE tube is also engineered to have a con-
trolled wall thickness and production methods ensure optimum hoop strength, there-
fore providing an excellent pressure/vacuum to temperature ratio in the finished
product. In most cases this can match that of PTFE lined steel pipe and fittings.
The PROCO Series 4400 is available in 2 convolute through 10 convolute configura-
tions. Each convolution profile offers different overall lengths (face-to-face dimen-
sions) and movements to fit the required specification.
Absorbs Pipe-Wall And Fluid-Borne Noise. The PROCO quiet-operating Series
4400 expansion joints are a replacement for “sound transmitting” metallic/lap
joints. Pipe-Wall sound loses energy and is absorbed as the noise carried by the
piping enters and exits the PTFE section. Fluid-Borne noise is absorbed by the
volumetric expansion (breathing of the connector). This action cushions water
hammer and smoothes out pumping impulses.
Isolates Vibration And Motion. PROCO Series 4400 PTFE Expansion Joints should
be installed right after and ahead of equipment generating vibration in order to
isolate the rotating/vibrating equipment from the rest of the piping system. This
layout will improve the overall operating performance of the piping system. For
optimum performance, the Series 4400 expansion joints should be installed hori-
zontally to the shaft. Vertical and perpendicular installations are also acceptable, as
these expansion joints will accept axial, lateral and angular movements as well as
vibration. Note: For maximum vibration transmission reduction, the pipe section
beyond the PTFE expansion joints must be anchored or sufficiently rigid.
Reduces System Stress and Strain. Rigid attachment of piping to critical or
mechanical equipment can produce excessive loading. Thermal or mechanically
created strain/stress/shock are cushioned and absorbed with the installation of a
flexible PROCO Series 4400 PTFE Expansion Joint. The Series 4400 expansion
joint adds a flexible component to the system that automatically self-corrects for
misalignment created by structural movements caused by settling, pipe expan-
sion or ground shifts.
Tested Force Pound And Spring Rate Tables. At PROCO we have machine tested
several sizes of the Series 4400 expansion joints for Axial Spring Rates and can
provide Thrust/Force factors so designers can properly design system restraints.
It should be noted that the Series 4400 Molded PTFE Expansion Joints are in
accordance wi th the per formance character ist ics of the Fluid Seal ing
Association’s Rubber Expansion Joint Division, Technical Handbook Section on
Convoluted PTFE Bellows.
Flange And Limit Rods. All PROCO Series 4400 expansion joint flange configu-
rations are made of ductile iron, coated with a rust inhibitive primer to prevent
corrosion and are dimensionally tapped to ANSI 125/150# Standards. Hole drill-
ing on centerline, other drilling standards, or other flange materials, (such as
epoxy coated flanges), are available on special order. In addition, all PTFE expan-
sion joints are supplied with factory set limit rods to prevent over-extension dur-
ing operation.
Chemical Service Capability at Minimal Cost. Expensive, exotic metal or PTFE or
FEP lined rubber expansion joints for severe chemical service can be replaced with
the PROCO Series 4400 PTFE Expansion Joints. The PTFE bellows are vanstoned
to ductile iron flanges, which allows all wetted surfaces to come in contact with the
PTFE material. Specify the Series 4400 expansion joints where high temperatures
coupled with lower pressures or lower temperatures coupled with higher pres-
sures are proposed. Molded from PTFE materials, the Series 4400 offers a low-
cost expansion joint that is impervious to chemical attack. Use the PROCO “Chemi-
cal to Elastomer Guide” for reference on chemical compatibility.
Services And Locations. PROCO Series 4400 PTFE Expansion Joints have been
supplied to, and successfully used by a range of customers worldwide in the
process industries for use in both organic and inorganic chemical processing
and production, including such demanding applications as agrochemical and phar-
maceutical chemical production, acid processing and food manufacture.
