Armor Plate® 360 ZED (Cold Temperature) Pipe Wrap
For External Corrosion and Mechanical Damage
I. GeneralArmor Plate® Pipe Wrap (APPW) is a composite structural pipeline repair system. APPW is designed to repair pipelines while in service without depressurizing or lowering the Maximum Allowable Operating Pressure (MAOP). APPW is a 3-part system (Resin, Putty and Armor Fiber®) specially designed for repairing straight pipe, elbows, tees, risers, reducers, wrinkle bends and most any pipe configuration with external corrosion or mechanical damage. Once cured, the AP 360 ZED System has been tested and designed for operating temperatures ranging from -60º F to 160º F (-51º C to 71º C). The AP 360 ZED Pipe Wrap System may be applied in world-wide environments with ambient temperature and/or operating temperature ranging from 32° F to 60° F (0° C to 16° C). The AP 360 ZED System Kit contains Resin A & B, Putty A & B, Armor Fiber® and all necessary equipment for application in the field. The APPW System is recognized by DOT as a permanent repair product and as the model for composite repairs. When a buried pipeline has been exposed and the repair is complete, the area may be backfilled the same day.
Armor Plate® 360 ZED Pipe Wrap is user-friendly and is applied by certified installers.
II. Surface Preparation
Prepare the repair area surface by grit blasting, power tool cleaning or hand tool cleaning. For grit blasting, the best surface is a near white metal (NACE 2, Swedish Sa 2½ or SSPC SP10) finish with a 2 to 3 mil anchor pattern. For power tool and hand tool cleaning, remove all loose dirt and debris, rust, and other contaminants that reduce adhesion. A roughened, clean surface is necessary to properly install the APPW System. The area prepared for the APPW Installation must extend 2 inches (5 centimeters) or more beyond both edges/sides of the anomaly/anomalies. The area to be wrapped should be thoroughly wiped with Acetone, MEK, Xylene or equivalent, if possible.
III. Required Number of Wraps
1.) On external corrosion, the required number of wraps of Armor Plate® Pipe Wrap is determined by using ARMOR CALCTM. ARMOR CALCTM is an engineered and tested program that uses the pipe size, nominal pipe wall thickness, pipe grade, corrosion depth and corrosion length. The ARMOR CALCTM will then determine how many wraps to apply to bring the pipe back to greater than the MAOP.
2.) The Armor Plate® Pipe Wrap System is designed to repair almost any external corrosion depth or pipe wall loss up to 80 per cent of the nominal wall thickness. The APPW system prohibits the repair of pipes containing 80 per cent or more wall loss as a safety factor.
3.) On a dent, gouge, manufactured defect or wrinkle bend (mechanical damage), the pipe wall thickness is multiplied by 1.5, then divided by the thickness of the Armor Fiber® (.0625 inches) to determine how many wraps to apply to bring the pipe back to greater than the MAOP. This formula is not shown on the ARMOR CALCTM Program. Any sharp edges should be removed and an inspection should be performed to identify cracks. Cracks must be removed before installing the APPW Product.
*Note: The Armor Plate® Pipe Wrap System is installed with the required number of wraps for each repair area. Two wraps is the minimum number of wraps to apply. A typical repair using APPW is normally 5, 6 or 7 wraps. However, if the pipe wall or damage is severe, the number of wraps may be higher based on the pipe data.
IV. Installation
1.) Measure the circumference of the pipe and add 2 inches (5 centimeters) or more, to provide an overlap of the trailing end over the leading end of the Armor Fiber®. Cut the Armor Fiber® for the required number of wraps, as per the measurement in the circumferential direction. If the “required number of wraps” is more than 4 wraps, add 2 inches (5 centimeters) or more to the cut length of the Armor Fiber® in order to accommodate the increase in the outside diameter. This should be done for each additional 4 wraps. Example: If the circumference of the pipe is 25 inches (63½ centimeters) around, the Armor Fiber® should be cut 27 inches or more (68½ centimeters or more) long for a 2 inch (5 centimeter) or more overlap at the trailing end on each wrap of Armor Fiber®. 2.) Once the surface of the pipe repair area is ready, it is now time to mix the resin for priming and saturating the Armor Fiber®.
3.) The mixing ratio for the AP 360 ZED Pipe Wrap System is 2:1. Mix two Parts A to one Part B when mixing the resin and the putty. This system is designed to set up in cold environments.
4.) Mix the AP 360 ZED Epoxy Resins using two Parts A Resin (white) to one Part B Resin (black) with stirring sticks and containers located in the AP 360 ZED Repair Kit. Mix vigorously for 2 to 3 minutes until the resin color becomes gray. On larger repairs, you may use a drill with a mixing paddle. Mix material until there are no white or black streaks in the resin, resulting in a final homogenous gray color.
5.) Mix the AP 360 ZED Epoxy Putty using two Parts A Putty (white) to one Part B (black) with stirring sticks and cardboard located in the AP 360 MP Repair Kit. Mix until the putty color becomes gray and there are no white or black streaks in the putty, resulting in a final homogenous gray color.
6.) Apply the putty to all voids, pitting, mechanical damaged areas and/or irregular surfaces. Smooth over the putty, in order to produce a smooth, uniform and transitional surface.
7.) Using a brush or roller provided, apply a primer coat of the mixed portion of the AP 360 ZED Resin to the entire pipe surface and over the putty in the repair area.
8.) With a roller, completely saturate the Armor Fiber® on the rough side (chopped strand) first, then turn the Armor Fiber® over and completely saturate the smooth side, using the mixed AP 360 ZED Resin.
9.) Once the Armor Fiber® is saturated, with the rough side down and the smooth side exposed, roll the Armor Fiber® onto the 2 inch x 2 inch wide x 15 inch long wooden applicator. The Armor Fiber® is now ready to be applied over the pipe repair area.
10.) With the rough side facing the pipe surface, position the leading end of the saturated Armor Fiber® onto the pipe surface (near the top center of the pipe surface on a horizontal pipeline). Hand tension the Armor Fiber® and wrap the Armor Fiber® around the circumference of the pipe. As you wrap the circumference of the pipe, smooth out the wrap, in the circumferential direction, using gloved hands to prevent air pockets, voids or wrinkles. You should now have one wrap and one linear foot of pipe covered. The wrap should be straight and even around the pipe. Each additional wrap should always be applied in the same circumferential direction as the previous wrap.
*Note: For buried pipelines and future Smart Pig Runs (ILI), if a “Marker System” is desired to identify a repair that has been previously completed, the following are some suggestions we offer:
A.) Once the first wrap of Armor Fiber® is in place, install 2 or more wraps of metal banding material about 1 or 2 inches from each inside edge of the Armor Plate® Pipe Wrap Installation. Then complete the Armor Plate® Pipe Wrap Installation.
B.) Once the Armor Plate® Pipe Wrap Installation is complete, install 2 or more wraps of metal banding material about 1 or 2 inches from each outside edge of the Armor Plate® Pipe Wrap Installation.
C.) Once the first wrap of Armor Fiber® is in place, install a metal object of choice or magnet (at the 12:00 o’clock position on a horizontal pipeline) about 1 or 2 inches from each inside edge of the Armor Plate® Pipe Wrap Installation. Then complete the Armor Plate® Pipe Wrap Installation.
D.) Once the Armor Plate® Pipe Wrap Installation is complete, install a metal object of choice or magnet (at the 12:00 o’clock position on a horizontal pipeline) about 1 or 2 inches from each outside edge of the Armor Plate® Pipe Wrap Installation.
11.) Continue wrapping the pipe until the desired number of wraps is obtained for each linear foot section. If you are installing more than a one linear foot section, stagger each wrap by half an inch or more to cover the circumferential seam on the previous layer. Make sure multiple wraps in a single layer are adjacent but not overlapping.
12.) After the “required number of wraps” is installed, mix the AP 360 ZED Putty. Apply the putty to each exposed circumferential seam, to both edges and at the trailing end of the Armor Fiber®. These areas should be covered with approximately one inch (2½ centimeters) in width of putty to insure the wrap is properly sealed, thus completing the repair. Depending on the ambient temperature, the repair will cure and harden in approximately 2 hours or more. The Armor Plate® Installation will remain tacky until the cure time has been reached. Once the system has cured, you are now ready to backfill the same or next day, if this repair was on a buried pipeline that has been exposed.
*Note: It is recommended that the Installation Crew or a Crewmember remain on site until there is satisfaction that the progression of the curing is acceptable.
V. Materials Kit sizes are based on square footage (12.5, 25, 50, or 100 square foot kits). Each kit will repair any variation of pipe diameters. For example: The same 100 square foot kit may repair 8 inch pipe, 14 inch pipe or a 36 inch pipe all at the same time, depending on the number of wraps and the linear feet of the repair.

VI. Characteristics
1.) The AP 360 ZED Pipe Wrap System is user-friendly.
2.) The mix ratio is 2:1 (2 parts A to 1 part B) for the AP 360 ZED Resin and Putty.
3.) The AP 360 ZED Pipe Wrap System is designed for application in ambient temperatures or on pipe surface temperatures ranging from 32° F to 60º F (0º C to 16º C).
4.) The AP 360 ZED Pipe Wrap System may be applied in most cold weather conditions (damp, sleet, snow).
5.) The AP 360 ZED Pipe Wrap System has been tested and designed for operating temperatures ranging from -60º F to 160º F (-51º C to 71º C).
6.) The AP 360 ZED Pipe Wrap System can usually be applied by two field crewmembers. On larger repairs a crew of four field crewmembers is required. They can usually apply between 75 and 125 square feet of material per hour, depending on the severity of weather conditions and/or access to the repair area.
7.) Estimating Coverage: One gallon of Armor Plate® Pipe Wrap 360 ZED Resin will saturate approximately 25 square feet of Armor Fiber®. VII. Curing
1.) If the ambient temperature is below freezing, we recommend warming the resin and putty to above 32º F (0º C). This will insure the resin and putty will mix easier and apply faster. Once the resin or putty has been mixed, it will set up below 32º F (0º C).
2.) The AP 360 ZED Pipe Wrap System will cure on condensating and wet pipe. A primer coat of the AP 360 ZED Resin will displace moisture. The best practice is to wipe the pipe surface dry and apply the Resin immediately.
3.) One quart mass of mixed Armor Plate® 360 ZED Resin and Putty will have a pot life of approximately 60 minutes at 32º F (0º C).
4.) The AP 360 ZED System contains ultraviolet (UV) inhibitors. An additional layer of paint or coating can be applied for additional protection.
5.) After the AP 360 ZED Pipe Wrap System has completely cured, it will withstand operating temperatures of -60º F to 160º F (-51º C to 71º C).
VIII. Storage and Handling
1.) The Armor Plate® 360 ZED Pipe Wrap components must be kept dry. The Epoxy Putty, Epoxy Resin and Armor Fiber® must be stored in a dry area, or covered in order for the application equipment and Armor Fiber® to perform properly.
2.) Freezing temperature will not harm any of the AP 360 ZED components. Parts A & B of the Resin & Putty and Armor Fiber® may be stored in sub-zero conditions. If the Resin and Putty are stored below freezing you may use minimal heat or place in an area above freezing and the system will be ready for installation.
3.) The Armor Fiber® must be completely dry at the time of mixing to achieve proper saturation.
4.) The Shelf Life on resin and putty - minimum two years.
IX. Cautions and Warnings
1.) AP 360 ZED Pipe Wrap is a safe system, but we recommend usage of the safety equipment: rubber gloves, Tyvek suit, proper eye wear, etc.
2.) Use AP 360 ZED Pipe Wrap in well-ventilated areas and avoid directly breathing fumes while mixing and saturating the Armor Fiber.
3.) Avoid skin contact if possible. Gloves and safety glasses are recommended.
4.) Use soap and water to thoroughly clean contaminated areas of the body.
5.) In case of eye contact, thoroughly flush the eye with water and seek immediate medical attention.
The Armor Plate® Pipe Wrap System saves time, money and labor costs. The APPW System is safe, user-friendly and may be applied in less than one hour, depending on the size of the repair. We appreciate your business.
