SECTION 1Pipeline Repair Systems


Pipeline Repair Systems• Armor Plate® Pipe Wrap (“APPW”) is a composite structural reinforcement

pipeline repair system to be applied by certified installers/applicators.

• APPW is designed to repair pipelines while in service.

• APPW is a 3-part system (Resin, Putty & Armor Fiber®) specially designed forrepairing straight pipe, elbows, tees, reducers, wrinkle bends, branch connectionsand most any pipe configuration with external corrosion or mechanical damage.

• The APPW Systems contains Resin A & B, Putty A & B, Armor Fiber® and allnecessary equipment for application in the field.

• The APPW Systems are recognized by PHMSA/DOT as a permanent repair productand as the model for composite repairs.

• There are four (4) Armor Plate® Pipe Wrap Repair Systems.


1. Armor Plate® 360 MP Pipe Wrap(Multi-Purpose)

• Cured System Operating Temperature: -60° F to 195° F (-51° C to 91° C)

• Application Temperature: From 60° F to 120° F (16° C to 49° C). Warmtemperatures may require tenting to provide shade for mixing and application.Cool temperatures may require external heat for mixing and application below60° F (16° C).

• Can be properly applied out of water but not in water or under wet conditions.

• Mix Ratio: 1:1 (equal amounts)

• Cure Time: Approximately 2 hours at 85° F (29° C)

• Pot Life / Working Time: Approximately 45 minutes at 75° F (24° C)

• Shelf Life: Minimum 2 years (sealed containers)


2. Armor Plate® 360 UW Pipe Wrap(Under Water)


• Application Temperature: Ambient temperature above 60° F (16° C)

• Designed for “wet” conditions or submerged piping. Can be properly appliedin the water and out of the water.

• Mix Ratio: 1:1 (equal amounts)

• Cure Time: Approximately 24 to 48 hours, depending on water temperature




3. Armor Plate® 360 HT Pipe Wrap(High Temperature)


• Application Temperature: From 180° F to 250° F (82° C to 121° C) onoperating pipe. May be applied at ambient temperature, put the pipe intoservice and allow operating temperature of 180° F to 250° F (82° C to 121°C) to cure the wrap.

• Mix Ratio: 1:1 (mixed before shipped)


• Pot Life / Working Time: N/A - Must reach approximately 180° F (82° C) tobegin curing.

• Shelf Life: Minimum 6 months after mixing (sealed containers)


4. Armor Plate® 360 ZED Pipe Wrap(Cold Temperature and Sub-Zero)


• Application Temperature: Below 55° F (13° C). Not recommended for application above 55° F (13° C). In arctic or cold climates – need tenting with heaters.

• Mix Ratio: 2:1 – Two (2) parts A to one (1) part B





SECTION 2Pipeline Coating Systems


Pipeline Coating Systems

• Long-term Corrosion Barrier

• Designed as a non-structural pipe coating that is more durable than tapecoatings, paint, and wax.

• May be used for preventing corrosion on girth welds, soil interface,exposed ground lines and final coating on APPW.

• There are two (2) Armor Plate® Pipeline Coating Systems.


1. Armor Plate CoatingAP 370 PLC

• 2-Part System: Epoxy Resin A & B and Fiberglass Cloth Tape

• 1:1 Mixing Ratio

• Light gray, in color

• Cure time: Approximately 2 hours at 85° F (29° C)


2. Armor Plate CoatingAP 385 PMC

• Uses 2-Part Ceramic Filled Components

• 5:1 Mixing Ratio

• Brush applied at 30 to 40 mils, no accelerator needed

• Light gray, in color

• Cure time: Approximately 45 minutes at 85° F (29° C)


SECTION 3Surface Preparation


Surface Preparation• Surface preparation is important for all APPW Pipeline Repair Systems.

• Grit Blasting - The best surface is a near white metal (NACE 2, Swedish Sa 2½ orSSPC SP10) finish with a 2 to 3 mil anchor profile.

• Hand Tool and Power Tool Cleaning - Remove all loose dirt, debris, rust, andother contaminants that reduce adhesion. A roughened, clean surface isnecessary to properly install the APPW System.

• The area prepared for the APPW Installation must extend 2 inches (5centimeters) or more beyond both edges/sides of the anomaly/anomalies.

• The area to be wrapped should be thoroughly wiped with Acetone, MEK, Xyleneor equivalent, if possible.


SECTION 4Determining the Number

of Wraps


• The required number of wraps of Armor Plate® Pipe Wrap is determined byusing ARMOR CALC®.

• ARMOR CALC® is an engineered and tested program that uses the pipe size,nominal pipe wall thickness, pipe grade, corrosion depth and corrosion length.

• The ARMOR CALC® will then determine how many wraps to apply to bring thepipe back to greater than the MAOP.

Determining the Number of Wraps

External Corrosion


• On a dent, gouge, or manufactured defect (mechanical damage), the pipewall thickness is multiplied by 1.5, then divided by the thickness of the ArmorFiber® (.0625 inches) to determine how many wraps to apply to bring thepipe back to greater than the MAOP.

• This formula is not shown on the ARMOR CALC® Program.

• Any sharp edges should be removed and an inspection should be performedto identify cracks.

• Cracks must be removed before installing the APPW products.


Mechanical Damage


• The Armor Plate® System is designed to repair almost any externalcorrosion depth or pipe wall loss up to 80% of the nominal wall thickness. ForTechnical Support, please contact Armor Plate, Inc. at 281-487-2023.

• The Armor Plate® System is installed with the required number of wraps foreach repair area.

• Two wraps is the minimum number of wraps to apply to assure that the APPWApplication is free of pinholes, most commonly referred to as holidays.



SECTION 5Installation Guidance


Installation• Measure the circumference of the pipe and add 2 inches (5 centimeters) or more.

• Cut the Armor Fiber® for the required number of wraps. If the “required number ofwraps” is more than 4 wraps, add 2 inches (5 centimeters) or more to the cut lengthof the Armor Fiber® in order to accommodate the increase in the outside diameter.This should be done for each additional 4 wraps.

• Once the surface of the pipe repair area is ready, mix the resin for priming andsaturating the Armor Fiber®.

• Mix Epoxy Putty and apply to all voids, pitting mechanical damaged areas and/orirregular surfaces to provide the “load transfer” between the pipe surface and theArmor Plate Repair. Smooth over the putty, in order to produce a smooth, uniformand transitional surface.


Installation• Completely saturate the Armor Fiber® on the rough side (chopped strand) first,

then turn the Armor Fiber® over and completely saturate the smooth side.

• Roll the Armor Fiber® onto the wooden applicator.

• Place the rough side facing the pipe surface. Hand tension the Armor Fiber®and wrap the Armor Fiber® around the circumference of the pipe. Smooth outthe wrap, in the circumferential/hoop direction, using gloved hands to preventair pockets, voids or wrinkles. You should now have one wrap and one linearfoot of pipe covered. The wrap should be straight and even around the pipe.Each additional wrap should always be applied in the same circumferential/hoopdirection as the previous wrap.


Installation• Continue wrapping the pipe until the required number of wraps is obtained. If

you are installing more than one linear foot section, stagger every otherwrap/layer by half an inch or more to cover the circumferential seam on theprevious layer (Example: After first wrap, move second wrap over by half aninch or more to the right. On third wrap, move over by half an inch to the left.Continue this process until the required number of wraps is obtained). Makesure multiple wraps in a single layer is adjacent (butted-up and touching) butnot overlapping.

• Note 1: When installing multiple continuous wraps for more than a one linearfoot area of repair on small diameter pipe, use the same stagger technique perapplication to cover the circumferential seam on the previous application.

• NOTE 2: When installing only two wraps, as a corrosion barrier, for more than aone linear foot section, you can deviate from the above procedure byoverlapping the edges instead of staggering. Also, when repairing “Bends” andother configurations, overlapping of the edges is acceptable.


Installation• Once the APPW System is properly installed and cured, you can backfill the same

or next day and it restores the strength above the Maximum Operating Pressure(MOP) of the pipeline.

• After the APPW is installed, the application of external heat reduces the timerequired for curing of the APPW System.

• It is recommended that the Installation Crew or a Crewmember remain on siteuntil there is satisfaction that the progression of the curing is acceptable towhere it will not sag at the bottom portion on a horizontal application or slide ona vertical application.

• A “Marker System” , such as metal banding, metal objects or magnets, can beused for future Smart Pig Runs on buried pipelines.
