HydraWrap™ Fiber Reinforced Polymer Composite

HYDRATECH MARINE HYDRAWRAP® SYSTEM - NOW AVAILABLE IN A CONVENIENT KIT! Marine HydraWrap Fiber Reinforced Polymer Kit

Adobe Acrobat Reader HydraWrap® for Industrial/Marine Pipeline Repair (quick reference)

HydraWrap® is an FRP (Fiber Reinforced Polymer) repair system engineered to restore or enhance the structural integrity of pipe and infrastructure.

Marine HydraWrap Fiber Reinforced PolymerEach HydraWrap® system is a uniquely designed high performance Carbon Fiber Reinforced Polymer (CFRP) Composite that consists of a 100% solids high build epoxy Primer, a 100% solids epoxy Wet-Out resin, and carbon fiber fabric.

The Primer provides excellent adhesion to a variety of substrates while allowing a sag free application at high film builds.

The Wet-Out resin is designed to thoroughly wet out the fiber forming a composite matrix with a very high tensile and flexural properties.

HydraWrap™ provides a rapid, chemical and corrosion resistant structural repair with no hot work required.

SUBSTRATE PREPARATION

Substrate preparation dictates the adhesion performance of any coatings system. A properly prepped surface will ensure maximum life and performance of the system.

 

APPLICATION REQUIREMENTS

Minimum Application Temp. 40ºF (4.4ºC)
Maximum Relative Humidity 85%
Substrate Temperature 5ºF (3ºC) above dew point
Thinning Do not thin
Cleaning Fluid Universal Equipment Cleaner
Note To aid application at low temperatures, both components should be warmed to 60-68ºF (15.5-20ºC) prior to mixing.

Consult HydraWrap® TDS for specifics regarding each HydraWrap system. Consult product MSDS for safety related information.

 

INSTALLATION PROCEDURE

Prep Surface
Identify and mark area for repair. Prep surface to give clean dry white metal with rough profile. All sharp edges are to be removed and any voids filled with putty.

Measure Fabric
Measure fabric around area to be repaired providing at least two layers of fabric. Cut fabric to desired length.

Prepare Surface
Combine and Mix Primer
Segregate Primer containers from Wet-Out containers. Pour contents of one container of A side Primer into one container of B side Primer. Scrape out A side container ensuring any residual contents are combined with B side. Mix with jiffy mixe until color is uniform throughout. 1-2 minutes
Combine and Mis Primer

Apply Primer
Apply primer using supplied spreader to the prepped surface ensuring complete coverage and no drips or runs.

Combine and Mix Wet-Out
Combine Wet-Out using same procedure as was used for Primer. Thoroughly mix with Jiffy mixer for 2 minutes.

Apply Primer
Apply Wet-Out to Fabric
Lay out dry fabric on clean non porous surface (table covered in plastic) and saturate with Wet-Out using supplied spreader. Ensure fabric is completely saturated then squeegee out excess resin. Role fabric on cardboard tube or roller.
Apply Wet-Out to Fabric

Install Saturated Fabric
Center fabric over repair and wrap around with consistent uniform pressure ensuring fabric is snug around pipe. Two wraps will give the minimal two required layers of fabric. Additional layers will provide additional structural support. Leave 1” exposed primer on either side of fabric. Any entrapped air is to be worked out of the fabric by applying pressure via spreader.

Cure
A top coat can be applied to the repair after 3 hours.HydraWrap™ will develop full physical properties within 24 hours of application.

Install Saturated Fabric

Wrap Techniques for Standard Shapes

WELD REPAIR

Tee Repair Step 1
Center the carbon fabric over the area to be wrapped. Press the fabric into the primer. Weld Repair Step 1
Unroll the fabric and wrap it around the pipe keeping it centered on the pipe and overlapping at the end. Tug gently to ensure that the wrap is tight. Weld Repair Step 2
Using a spreader, notched roller, or gloved hands remove all air, wrinkles and smooth ends from the fabric.

 

SPIRAL REPAIR

Spiral Repair
Commence repair with one full circumferential wrap. Spiral Repair Step 1
Form a spiral wrap by overlapping each turn by no less than 50%. Tug gently during the spiral process to ensure the wrap is tight and that no wrinkles or air bubbles are present. Spiral Repair Step 2
Terminate repair with one full circumferential wrap. Spiral Repair Step 3
Using a spreader, notched roller, or gloved hands remove all air, wrinkles and smooth ends from the fabric. For additional layers, start at the completed end and spiral in the opposite direction.

 

ELBOW REPAIR

 
Begin with one complete wrap of fabric overlapping the weld. Elbow Repair
Press the fabric into the primer and then spiral the fabric so that each successive pass covers 50% of the fabric on the external arc of the bend. Tug gently during the spiral process to ensure the wrap is tight and that no wrinkles or air bubbles are present. Terminate repair with one full circumferential wrap overlapping weld. Spiral Repair Step 1
Using a spreader, notched roller, or gloved hands remove all air, wrinkles and smooth ends from the fabric. For additional layers, start at the completed end and spiral in the opposite direction.

 

 

TEE REPAIR

Tee Repair
Tees require four pieces of fabric for the legs and two wider pieces of fabric (four times as long as the pipe is wide) called a Diaper. This diaper is wrapped under the straight portion of the tee up to the branch. Tee Repair Step 1
The diaper piece is installed first. The diaper is centered over the straight run of the tee covering the body of the tee with the fabric wrapped up the side of the tees. To prevent wrinkles the cloth must be cut or notched at the base of the side outlet. Tee Repair Step 2
At each leg, begins with the fabric overlapping the weld. Make one complete wrap over the weld, pressing the fabric into the primer and then spiral the fabric so that each successive pass covers 50% of the fabric. Tee Repair Step 3
Tug gently during the spiral process to ensure the wrap is tight and that no wrinkles or air bubbles are present. Tee Repair Step 4
At the outlet end of the leg, complete one full turn, then wrap fabric across the tee and complete one wrap around the opposite end of the tee to terminate. After completion of first two legs, apply second diaper and use remaining two pieces of fabric to wrap third leg (lateral) both starting on lateral but terminating one on each of the first two legs. Tee Repair Step 5
Using a spreader, notched roller, or gloved hands remove all air, wrinkles and smooth ends from the fabric.
