INTENDED USE
The PROTEC Model PRO-8-1000-MSP Pressure Vessel is
designed for continuous use as a housing for membrane filtration
elements to purify typical seawater waters at any positive
pressure up to 1000 PSI. The PRO-8-1000-MSP will
accommodate any make of eight-inch nominal diameter spiral-
wound element as well as many hollow fiber elements. The
element interface hardware for the specified element is supplied
with the vessel.
The Model PRO-8-1000-MSP has been designed to meet the
standards of the American Society of Mechanical Engineers
(ASME), Boiler and Pressure Vessel Code, Section X. At an
additional cost, vessels can be inspected during fabrication by an
ASME Authorized Inspector and Code stamped.
The Model PRO-8-1000-MSP must be installed, operated and
maintained using good industrial practice and following the
precautions listed in order to help assure safe operation and a
long service life. Misuse, improper installation or operation may
result in severe bodily harm or property damage and will void the
vessel warranty. Therefore, review and follow the safeguards
listed below before placing the vessels into service.
The filament-wound reinforced plastic shell of this vessel must
be allowed to expand under pressure. Any undue restraint at the
support points or piping connections can cause non-repairable
leaks to develop in the shell. This vessel must not be subjected
to excessive stress caused by bending moments acting at the
side ports in the fiberglass shell.
The end closures and side ports of the vessel must be kept dry
and free of corrosion at all times. Failure to do so may result in
deterioration that can lead to catastrophic failure of the vessel
heads.
When requested, Bekaert Progressive Composites will assist the
purchaser in determining the suitability of this standard vessel
design for their operating environment. However, the final
determination including the evaluation of the materials of
construction for use in the specific corrosive environment shall
be the responsibility of the purchaser. Alternate materials of
construction may be available on special order.
Before using this engineering packet for system design or vessel
installation, please verify that it is the latest revision by consulting
the factory. Specifications are subject to change without notice.
PRECAUTIONS
Follow all instructions.
Failure to take every precaution listed will void the vessel
warranty and may result in vessel failure.
Mount shell using furnished hardware.
Following the recommended span(s), mount the vessel on
saddles provided. Tighten straps to one ft-lb maximum.
Align the side ports with the manifold.
Center each vessel with the manifold and correct the causes
of misalignment for each and every vessel.
Use flexible type groove-end pipe couplings.
Use Victaulic™ style 77 or equal couplings at each side port
and allow a gap between each port /manifold connection as
specified by coupling manufacturer.
Maximize the connection flexibility.
Position the vessel and the piping so that the vessel can grow
in length and diameter under pressure without any undue
restraint. ∆DIA = 0.012 in. (0.3mm) and ∆L = 0.25 in. (6mm)
for a length code –7 vessel.
Provide overpressure protection.
Set the safety device at not more than 105% design pressure.
Inspect end closures and side ports regularly.
Replace damaged or deteriorated components and correct the
cause of any corrosion.
Relieve system pressure before working on the vessel.
Working on vessels that are under pressure may result in
bodily harm and/or property damage.
Never support other components with the vessel.
Hanging piping manifolds or supporting other components with
the vessel may result in vessel damage.
Do not over tighten the Permeate Port connection.
Tightening the connection more than one turn past hand tight
will damage the port.
Ensure that the Thrust Cone is installed downstream.
Operating without thrust cone may cause membrane damage.
Double check end closure installation.
Ensure that retaining ring is in place and fully seated.
Never operate the vessel in excess of its ratings.
This practice will void the vessel warranty, shorten vessel life
and could lead to bodily harm or property damage.
Do not operate the vessel permeate port over 125 psi.
Permeate pressure in excess of 125 psi must be approved by
the factory prior to operation.
Some components in the vessel are not compatible with
hydrocarbons. Contact factory for alternate material options.
Flush the vessel before system shut down.
Some feed waters may cause corrosion under static
conditions. Flushing with non-corrosive permeate is
recommended.
Operate the vessel within the recommended pH range.
The vessel is designed for continuous use at a pH of 3-11 and
for intermittent cleaning (less than 30 min. at a pH of 2-12).
Do not install the vessel in direct sun light.
*Please inform the factory when continuous operating temperature is less than 45°F.

HEAD LOADING PROCEDURE
Step 1 Inspect the Shell
Before installing the head, check the inside surface of the shell
for any imperfections or foreign matter. Remove all foreign matter
using a mild soap solution and rinse with clean water. To remove
imperfections, lightly sand the surface of the vessel with 600-grit
sandpaper and soapy water and then rinse with water can.
Step 2 Head Seal and Shell Lubrication
Ensure that the head seal is covered with a thin layer of glycerin
and is free from any dirt or dust contamination. Then lubricate the
inside of the shell starting directly inboard of the retaining ring
groove and up the energizing ramp into the vessel bore. Only a
thin layer is required. Silicone lubricants can also be used;
however, care should be taken to use as little as possible. Check
with your membrane supplier before using these lubricants as
they can foul membranes.
Step 3 Install Head
Holding the head square to the axis of the shell, slowly push the
head into the shell until the seal passes the retaining ring groove.
As a resistance is felt, tap the head in using a 2-3 lb dead blow
hammer until the head clears the retaining ring groove.
Step 4 Install Retaining Ring
Remove any moisture from the retaining groove before
proceeding. Carefully place the end of the retaining ring into the
groove on the shell. After the ring is started, slowly push the ring
towards the groove. As the ring enters the groove, continue
pushing as your hand slowly rotates counter-clockwise around
the inside diameter of the shell. Be careful to prevent the ring
from snapping against your finger as it enters the groove.
Step 5 Reconnect Permeate Port
Reconnect the permeate manifolding to the permeate port.
Step 6 Pressurize System
Before starting the system, double check that each head has
been correctly installed and that all piping connections are in
place. After ensuring that all required precautions have been
taken, start the system.
Step 7 Check for Leaks
After system start up, verify that all connections are leak free. Fix
any leaks at this time to prevent corrosion that may lead to
component deterioration and possibly unsafe operation.
HEAD REMOVAL PROCEDURE
Step 1 Shut Down System
Shut down system and take all steps necessary to relieve
system pressure from the vessel.
Step 2 Disconnect Permeate Piping
Carefully disconnect the permeate piping from the permeate port.
Set this piping in a secure place for re-assembly.
Step 3 Check End Closure
Examine the end closure for any corrosion or damage. Remove
any corrosion with a wire brush and flush away the deposits with
clean water. Order replacement components as required.
Step 4 Remove Retaining Ring
Pull the retaining ring out of the groove in the shell. After the ring
is removed from the groove for ¼ turn, stop pulling. Finish
removing the ring by running your finger behind the ring and
carefully pulling the ring from groove. It is best to follow the ring
in a clock-wise direction while removing to avoid stretching the
ring.
Step 5 Remove Head
Use the two tapped 5/16”-18 holes in the bearing plate to pull the
head out. It is recommended that you contact the factory for
head removal tools or instructions.
SIDE PORT SEAL REPLACEMENT
While it is possible to replace the side port seal without removing
the port, port removal is the best way to ensure that the seal
gland is not damaged and to inspect/recondition the gland as
required. Before this procedure is started, it is required that a
replacement retaining ring and a new port seal be purchased to
ensure correct port installation. A side port/seal installation kit
with instructions is available from the factory. Please contact the
factory for ordering.
Step 1 Remove Retaining Ring
Carefully remove the metal retaining ring from the side port as to
not damage the ring or the port.
Step 2 Remove Side Port
Mark the port and the shell to indicate correct port location for
installation. Rotate the vessel, until the port is in the 2 O’clock
position. Place a soft towel into the vessel bore to prevent any
possible damage. Using a rubber mallet, lightly tap on the port
from the outside of the vessel while holding the port from inside
the vessel. Continue to tap on the port until it is removed.
Step 3 Inspect Port
Inspect inside the port for any corrosion and remove any deposits
with a mild abrasive. Ports that have pitting or crevice corrosion
should be replaced. Inspect the sealing area of the port for areas
that may create sealing problems. Imperfections can be sanded
with 600-grit sandpaper and soap solution. If any imperfections
cannot be removed in this manner, port replacement is required.
Step 4 Inspect Shell
Sand the hole through with 80 grit emery cloth until the port
slides into the hole through freely. Inspect the sealing area of
the shell for areas that may create sealing problems.
Imperfections can be lightly sanded with 600-grit sandpaper and
a mild soap solution. If any imperfections cannot be removed in
this manner the port may leak. If this is found to be the case, the
vessel will require a factory technician to repair the damaged
area. Contact the factory for further information.
Step 5 Install the Port
Using the clocking marks from the port removal, install the port
into the vessel wall by pushing it from the inside toward the
outside of the vessel. Push the port into position until the snap
ring groove clears the outside of the shell.
Step 6 Install the New Retaining Ring
Carefully install the new retaining ring being very careful not
to stretch it out of shape. Feed one end of the ring into the
groove. Then walk the ring into the groove by pushing on
the ring with a small tool such as a screwdriver until the ring
is completely installed into the groove.
Step 7 Lubricate the New Seal
Lubricate the new seal with a thin layer of glycerin. Silicone
lubricants can also be used; however, use as little as possible.
Check with your membrane supplier before using these
lubricants as they can foul membranes.
Step 8 Install the New Seal
With the tongue depressor, push the seal all the way down at two
points across from each other. Then repeat the process in the
opposite direction. The seal should now be installed at four
corners. Carefully continue to push the seal into the gland by
alternating sides until the entire seal is installed.

HEAD REBUILDING
Prior to following this procedure, remove the head following the
procedure listed.
Step 1 Remove Adapter
Pull the adapter from the permeate port by slowly pulling on the
adapter body.
Step 2 Remove Permeate Port
Carefully remove the metal retaining ring from the permeate port
as to not damage the ring or the port. A new retaining ring may
be required to assemble the head. After the ring is removed,
carefully slip the bearing plate off the permeate port and set it
aside. Then simply pull the permeate port from the sealing plate.
Step 3 Remove Seals
Remove the seal from the permeate port and set aside. Using a
small tool, such as a screwdriver or a paper clip, remove the seal
from the inside of the permeate port and set aside.
Step 4 Clean All Components
Using a mild soap solution, clean each component, rinse with
fresh water and then dry with compressed air or a lint free towel.
Step 5 Inspect Components
Examine each component for corrosion or damage that may
affect the performance of the vessel. Replace any components
that have corrosion or visual damage. In addition, carefully
inspect each seal for damage or wear. It is recommended to
replace each seal at this time. Please be aware that seal
condition may affect system performance.
Step 6 Lubricate Seals
Using extreme care, coat each seal with a thin layer of glycerin.
Only a thin layer is required. Silicone lubricants can also be used;
however, care should be taken to use as little as possible. Check
with your membrane supplier before using these lubricants as
they can foul membranes.
Step 7 Reassemble Head
Reversing the removal procedure, reassemble the head. Please
note that a new permeate port retaining ring may be required to
ensure correct component performance.
PIPING RECOMMENDATIONS
PROTEC pressure vessels are the most durable side port vessel
available today. Unlike vessels with less durable designs,
connecting PROTEC side ported vessels to manifolding or to
each other is easily done if some very basic rules are followed.
These are as follows:
Use two flexible Victaulic™ connections when manifold
accuracy is questionable.
The tolerance required for side-ported vessels should be a total
per port of .030. For retrofitting side-ported vessels into older
systems or when manifold tolerances can simply not be
guaranteed, the two-connection method is the safest approach.
Use a single flexible Victaulic™ connection when manifold
accuracy is not a problem. This is possible when manifold to
vessel misalignment can be held to within .030 in any direction.
However, it is important to note that these flexible connections
allow angular but not lateral misalignment. Therefore, any
misalignment must be kept to a minimum.
Use intermediate Victaulic™ connections in the manifolds
when required. This practice allows more flexibility in the
system resulting in easier to install manifolds.
Center the vessel between the manifolds. This is very basic
but commonly overlooked. If the port on one end is directly
aligned with the manifold and the opposite is .060 off, centering
the vessel before tightening the straps allows each end to handle
.030. Do this with each vessel.
Allow one concentrate manifold to float. In some systems,
the manifold can be connected to the vessels and supported by
the floor but allowed to float in the axial direction to provide room
for vessel growth under pressure.
Let the manifold span be longer than the vessel span.
Remember that the vessel will grow in length under pressure.
Setting the manifold span on the long side is another way to
provide room for vessel growth under pressure.
Check each connection for acceptable misalignment.
By installing the Victaulic™ connection without the gasket and
drawing the bolts snug, the connector should be able to rotate by
hand. On some systems this test may not be practical. In these
cases the Victaulic™ connections must be able to be tightened
without the need of excessive force. Force would indicate a
major misalignment that could damage the vessel.
When in doubt, contact the factory.
MULTIPLE PORT
RECOMMENDATIONS
Multiple port vessels are those specified by the user to have
more than one high-pressure port per end. This feature allows
vessels to be directly connected together allowing water to flow
through one vessel into another. This piping method has
become an acceptable way to provide superior system designs
while reducing system costs.
While the thought of directly bolting vessels together is easily
understood, there are several guidelines that must be followed in
order to have a good long-term system design. These are as
follows:
Flow-balance the system.
When supplying feed water from one side of the vessels, take the
concentrate from the opposite side. This will prevent more water
from flowing through the first vessel and starting the second and
third. This practice will help equalize feed flow to each vessel.
Minimize pressure drop.
As water passes through each vessel, a pressure drop occurs.
This will result in the last vessel in a connected pass receiving
less pressure than the first. Increasing port size reduces this
effect.
Optimize the water velocity through the ports.
The speed of the water through the ports should be kept within a
reasonable range to ensure proper long-term performance
(typically 5-15 ft. per sec.) Speeds that are too fast result in port
erosion while speeds that are too slow will promote corrosion.
Consider feeding from the center of a pass or from both
ends.
This practice may eliminate problems with velocities that are too
high for proper system performance.
Avoid the temptation to use smaller ports.
Even though the thought of adding on an extra vessel with small
ports sounds reasonable, it can result in a pressure drop
problem.
Evaluate the effect of using larger ports.
Large concentrate ports may be desired for cleaning flows but
may have low velocity under normal operations.
Take caution when using more than one port size.
Changing ports sizes in a second or third pass requires careful
evaluation of pressure drop that can affect system performance.
Check with your membrane supplier.
It is a good idea to let your membrane supplier evaluate the
performance of your proposed system.
Don’t assume that we endorse the use of multiple ports for
your system.
Just because vessels can be ported together does not make
them the best choice for your system. Bekaert Progressive
Composites is not responsible for the misapplication of the
multiple port option.
