<strong>Depend</strong>-O-Lok® joining system
Victaulic mechanical pipe joining systems<br />
are known the world over for their ease<br />
of installation and reliable service.<br />
The Victaulic <strong>Depend</strong>-O-Lok line of couplings is<br />
another example of creating faster, easier, and more<br />
economical pipe joints. Designed for installation on<br />
a wide range of pipe sizes Victaulic <strong>Depend</strong>-O-Lok<br />
couplings provide a variety of repair and joining solutions.<br />
Victaulic <strong>Depend</strong>-O-Lok couplings join large diameter<br />
pipe using ten bolts and nuts versus the 52 bolts and<br />
nuts found on 144”/3650 mm sleeve type couplings<br />
that require star tightening three times to <strong>com</strong>plete<br />
the joint. Victaulic <strong>Depend</strong>-O-Lok couplings join<br />
many different types of pipe including carbon steel,<br />
stainless steel, ductile iron, HDPE, pre-stressed<br />
concrete and fiberglass.<br />
bolts and nuts<br />
closure plates<br />
double arched<br />
sleeve for strength<br />
o-ring gasket<br />
low profile<br />
sealing plate/pad<br />
restraint ring

REPAIR SOLUTIONS<br />
Victaulic also offers two unique and cost-effective<br />
repair solutions for reducing downtime during<br />
scheduled maintenance. An internally mounted<br />
coupling is used to rehabilitate piping systems from<br />
inside the pipe while the encapsulating coupling<br />
mounts over the outside diameter of the pipe<br />
without the need to remove the failing joint.<br />
See page 11 for more information.<br />
[ 1 ]
Non-Restrained Coupling<br />
E x E non-restrained coupling<br />
E x E non-restrained couplings are used where you<br />
need system access, but you don’t need a restrained<br />
joint. E x E non-restrained couplings can be restrained<br />
externally if required. Designed to meet or exceed<br />
the performance requirements of AWWA C227<br />
E x E non-restrained couplings will allow for angular<br />
deflection at the joint while maintaining full joint<br />
integrity. The coupling reduces vibration and<br />
is joined using as few as 3 bolts and nuts.<br />
Benefits<br />
• Up to 70% faster to install – no star – pattern<br />
tightening or re-torquing required.<br />
• Minimum space required for installation.<br />
• Allows faster and easier access to pipe and equipment.<br />
• Reduces maintenance downtime by up to 75%.<br />
• Available up to 144”/3650 mm and pressures<br />
up to 400 psi/2750 kPa.<br />
Rocky reach dam<br />
Rocky Reach Dam was constructed in 1956.<br />
But every year, up to 6% of the salmon and<br />
steelhead runs perished in its turbines during<br />
their seasonal migration to the sea. One alternative:<br />
spill 40% to 50% of the water by the dam,<br />
at a cost of reducing power generation by $25<br />
million a year. The second option: construct<br />
a pipe around the turbines so that fish could<br />
pass through unharmed. Today, the fish are<br />
collected upstream via pumps that conduct<br />
water flows of up to 7,000 cubic feet per second<br />
to attract the fish into the conduit. They are then<br />
transported through the 4,600-foot pipeline, held<br />
together by Victaulic couplings, to a discharge<br />
point on the downstream side of the dam.<br />
[ 2 ]
Expansion Coupling<br />
F x E expansion coupling<br />
F x E expansion couplings allow for<br />
longitudinal pipe movement. Restraint ring(s)<br />
welded to one pipe end keeps the coupling<br />
in-place over the joint while allowing the other<br />
pipe end to move to design specifications.<br />
Able to ac<strong>com</strong>modate up to 4”/101.6 mm of<br />
expansion/contraction in the piping system,<br />
the F x E expansion coupling is ideal for air<br />
systems. Since no rubber <strong>com</strong>ponents are<br />
exposed there is no risk of UV degradation<br />
of the joint. A variety of o-ring <strong>com</strong>pounds are<br />
available including silicone or fluoroelastomer<br />
for higher temperature service.<br />
Benefits<br />
• Allows for easy extension of penstock lines.<br />
• A single joint versus the two joints needed<br />
on AWWA C221 expansion joints.<br />
• Ac<strong>com</strong>modates up to 4”/101.6 mm<br />
of axial pipeline expansion or contraction.<br />
• Available with gaskets suitable for air<br />
temperatures up to +400°F/+204°C.<br />
• Available to 144”/3650 mm and for pressures<br />
up to 300 psi/2065 kPa.<br />
[ 3 ]
Restrained Coupling<br />
F x F restrained coupling<br />
F x F restrained couplings restrain pipe joints<br />
up to the full working pressure of the coupling<br />
with very little moment load transferred to the pipe.<br />
The coupling design allows for some pipe irregularities<br />
encountered during field installations. With far fewer<br />
bolts than <strong>com</strong>petitive products, F x F restrained<br />
couplings are much easier to assemble and<br />
disassemble than other types of restrained joints.<br />
LA department of water and power (LADWap) –<br />
Hollywood Valve Vault<br />
A valve vault is a costly yet crucial part of<br />
water systems. Every space reduction results<br />
in a corresponding reduction in the cost of<br />
time and materials to create the vault.<br />
So what does piping have to do with this?<br />
By specifying and installing Victaulic<br />
<strong>Depend</strong>-O-Lok couplings in the Hollywood<br />
Valve vault the LA district water authority was<br />
able to save hundreds of thousands of dollars<br />
in construction costs. Because <strong>Depend</strong>-O-Lok<br />
type couplings do not require external restraints<br />
the overall size of the system, the valve vault<br />
could be reduced by about 400 square feet.<br />
This translated into less concrete and time<br />
needed to <strong>com</strong>plete this project.<br />
BENEFITS<br />
• Up to 70% faster to install – No star-pattern<br />
tightening or re-torquing required.<br />
• Ac<strong>com</strong>modates many of the pipe irregularities<br />
encountered in the field.<br />
• Internal restraint much more economical than<br />
joints requiring external AWWA M11 harness.<br />
• Available with gaskets suitable for air temperatures<br />
up to +400°F/+204°C.<br />
• Eliminates field welding.<br />
• Available up to 144”/3650 mm and pressures<br />
up to 400 psi/2750 kPa.<br />
• Allows easy access to valves and equipment taking<br />
up much less space than an externally restrained joint.<br />
• Since less space is required for the coupling,<br />
a reduction in the footprint of the structure<br />
is possible; thereby reducing construction costs.<br />
[ 4 ]
Restrained Dynamic Coupling<br />
F x F modified restrained<br />
dynamic coupling<br />
F x F modified restrained dynamic couplings<br />
allow for dynamic deflection while restraining the<br />
joint at full bulkhead pressure. When these flexible,<br />
restrained joints are installed in pairs separated by a<br />
pipe spool (of calculated length) outside of a structure,<br />
the system allows for differential settlement between<br />
the structure and the pipe line. Using F x F modified<br />
restrained dynamic couplings can reduce the length<br />
of pipe needed to meet design criteria by up to 70%.<br />
The coupling design allows for some pipe irregularities<br />
encountered during field installations. With far fewer<br />
bolts than <strong>com</strong>petitive products, the F x F modified<br />
restrained dynamic coupling is much easier to<br />
assemble and disassemble than other types of<br />
restrained joints. The coupling’s low profile allows for<br />
much easier protection where corrosion is a concern.<br />
BENEFITS<br />
• Allows for dynamic, in-service deflection to<br />
reduce the pipe spool length needed for differential<br />
settlement by up to 70%.<br />
• 2 joints outside of structure meet AWWA C227<br />
deflection capabilities.<br />
• Easier to protect from corrosion than <strong>com</strong>petitive<br />
joining methods.<br />

AirMaster standard duty single gasket coupling for services up<br />
to 400 psi/2750 kPa and FluidMaster heavy duty single gasket<br />
coupling is rated up to 600 psi/4135 kPa. Each coupling style meets<br />
and exceeds the performance requirements of AWWA C606.<br />
[ 6 ]
Much lighter and easier to install than flanged joints<br />
Standard and heavy duty couplings can reduce<br />
installation time by up to 40%. Standard and heavy<br />
duty couplings also offer system designers a fully<br />
restrained joint without using external harness lugs.<br />
Restraint rings can be pre-installed by a fabricator<br />
thereby eliminating any field welding.<br />
BENEFITS<br />
• Ideal where there is restricted space for a joint.<br />
• Allows for some pipe diameter variation while fitting<br />
each joint perfectly.<br />
• Simple pipe end preparation.<br />
• Lower profile reduces weight and reduces installation<br />
time by up to 40%.<br />
• Provides fully restrained joint with no external harness lugs.<br />
• AirMaster single arch, standard duty is ideal for air,<br />
water and wastewater.<br />
• Is designed for use on wastewater aeration lines, odor<br />
control and duct and ventilation piping.<br />
• FluidMaster heavy duty is designed for higher pressure<br />
applications such as slurry piping where it is difficult<br />
to push the media through the line.<br />
• The ideal coupling for applications where only the gasket<br />
is be exposed to the media in the pipe line.<br />

OmniFlex metal bellows expansion joint<br />
OmniFlex metal bellows expansion joints allow for concurrent axial,<br />
angular and lateral pipe movement, with axial movement up to<br />
4”/102 mm. The stainless steel construction of the expansion joint<br />
is resistant to corrosion and UV degradation. OmniFlex metal bellows<br />
expansion joints can be provided with a variety of connection styles<br />
to meet the design needs of the system where movement on more<br />
than one plane is required. When prepared with a <strong>Depend</strong>-O-Lok<br />
coupling, OmniFlex metal bellows expansion joints eliminate the<br />
need for two additional stainless flanges, bolt and nut sets thereby<br />
reducing the cost and the weight of the joint.<br />

Encapsulating Repair Coupling<br />
repair solution<br />
When pipe joints leak<br />
and need to be repaired<br />
maintenance and downtime<br />
are costly and must be kept<br />
to a minimum. Victaulic<br />
repair couplings provide<br />
two unique and cost effective<br />
solutions for repairing pipe<br />
joints from either outside<br />
the pipe or inside the pipe.<br />
encapsulating repair coupling<br />
When maintenance is scheduled to repair leaking<br />
or failed joints, there is no faster, easier and economical<br />
method for repairing distressed pipe lines than the<br />
encapsulating coupling. The encapsulating repair<br />
coupling is ideal for repairing leaky Bell & Spigot joints,<br />
coupling joints and most other failed and leaking joints.<br />
The coupling consists of two housings that enclose<br />
the failed joint providing a new high pressure seal.<br />
The encapsulating repair coupling does not require<br />
removing and/or replacing the failed joint and can be<br />
installed without taking the system offline. Encapsulating<br />
couplings are manufactured to meet the size and<br />
pressure requirements of your system.<br />
BENEFITS<br />
• Repairs leaking joints without replacing the pipe or taking<br />
the system off-line.<br />
• Provides a new high pressure seal.<br />
• Easiest, fastest and most economical method for repairing pipe.<br />
• Available for most types of pipe.<br />
[ 10 ]
Internal Seal Repair Solution<br />
internal seal Repair coupling<br />
Ideal for rehab projects where excavation is difficult<br />
or deep, this internal seal system reduces the difficulties<br />
associated with repairing pipes that are experiencing<br />
leaking joints. All that is required is access to the system<br />
through a manhole or manway. The internal seal repair<br />
coupling allows you to use internal resources to greatly<br />
reduce the cost of repairs. This system produces savings<br />
of up to 75% versus conventional methods. Standard<br />
units are designed for pipe from 12”/300 mm up to<br />
144”/3650 mm with sizes as large as 218”/5500 mm<br />
available. Internal seal repair couplings are designed<br />
for systems with working pressures up to 300 psi/2065 kPa.<br />
BENEFITS<br />
• Up to 75% labor savings over<br />
traditional repair methods.<br />
• Repairs pipe from the inside<br />
using internal resources.<br />
• Available for a wide range<br />
of sizes and pressures.<br />
• Fixes cracks, holes,<br />
corrosion, deflection, offset<br />
and out-of-round pipe.<br />

Install Tools<br />
Victaulic <strong>Depend</strong>-O-Lok couplings are easier to install using<br />
the tools that are specifically designed to work with the line<br />
of Victaulic <strong>Depend</strong>-O-Lok style couplings.<br />
CT-1 Manual Tool FOR TYPE 1 COUPLINGS<br />
The CT-1 is offered in small and large sizes and is ideal for<br />
joining all externally mounted <strong>Depend</strong>-O-Lok style couplings.<br />
The tool brings the coupling housings together to allow the<br />
bolts and nuts to be installed.<br />
CT-2 Hydraulic Tool For Type 2 Couplings<br />
CT-2 Hydraulic tools can be used on all externally mounted<br />
<strong>Depend</strong>-O-Lok style couplings. Applying up to 10 tons of<br />
hydraulic force the CT-2 makes joining <strong>Depend</strong>-O-Lok style<br />
couplings faster, easier and more reliable.<br />
CT-3 Hydraulic Tool for Type 2 HP couplings<br />
CT-3 hydraulic tools are designed for joining type 2 HP couplings.<br />
Exerting over 25 tons of pressure the tool is the fastest, safest<br />
and easiest way to assemble high pressure type 2 HP couplings.<br />
ST-1 Internal Seal Spreader Tool<br />
The ST-1 is required to properly position and install the arched<br />
bands used with the internal seal repair couplings. The tool<br />
quickly positions and joins the band sections to <strong>com</strong>plete<br />
each section of the internal joint seal.<br />
[ 12 ]
Buried Services<br />
Low profile allows the couplings to be protected from corrosion<br />
on buried services. A variety of coatings can also be applied<br />
to the housing to inhibit corrosion.<br />
Fabrication<br />
Systems can be pre-fabricated with Victaulic <strong>Depend</strong>-O-Lok<br />
couplings for on site productivity. Assembled pieces can be<br />
positioned and field fitted to reduce on-site handling and<br />
project calendar days.<br />
Restrained or Unrestrained Joints<br />
Victaulic <strong>Depend</strong>-O-Lok couplings offer designers greater<br />
versatility. Each joint can be designed for restrained or<br />
unrestrained service to match the needs of the project.<br />
Sized to meet your needs<br />
Standard product is offered up to 144”/3650 mm with custom<br />
designed couplings available to meet the size and pressure<br />
requirements of your project.<br />
Abrasive services<br />
Victaulic <strong>Depend</strong>-O-Lok couplings do not reduce wall thickness<br />
or affect the inside diameter of pipe thereby providing a smooth<br />
flow path which is important on abrasive services like slurry lines.<br />
