Strong, Versatile — Ideal for Pipes and Structures in High Temperature & Harsh Chemical Environments.
PowerSleeve® is a high strength, field-applied composite system that is used for structural reinforcement of damaged piping. It is a wet layup, or field-pregged, fiber-reinforced polymer (FRP) system that consists of custom blended epoxy and unique fiber reinforcements tailored for piping repair. These products are suitable for pipes with leaks or which may develop leaks. A broad line of unique epoxy matrix systems and fabrics are available to handle a wide variety high heat applications (Up to 525° F), harsh chemical environments, and cool installation temperatures.
PowerSleeve®, our engineerd composite kit, consists of a fabric that is a hybrid alloy, non-crimped system, employing a high grade E-glass and Kevlar® yarns, arranged in a multi-axis layout that maximizes the ultimate composite strengths. This fabric is factory pre-treated using a state-of-the-art process which assures that all the micro-fibers in the wall will be matrix-wetted. Tests of these pre-treatments show a finished PowerSleeve® installation is much stronger than an untreated lay-up. We can also provide specialized fiber alloys and fiber types for your special applications.
The PowerMatrix™ grade is selected for your application type. We used custom formulations that give our product exceptional properties of flexibility, adhesion, toughness, chemical resistance, thermal resistance, vibration, etc. Special grades are available to handle special situations.
PowerSleeve® Kits ship to field with all components pre-measured and factory sealed. Everything is included: PowerSleeve® Fabric, PowerMatrix™, primer, stirring sticks, Stricture Banding™, paint, safety glasses, wipes, etc. This packaging format has many advantages. It eliminates field measuring of the epoxy components, and the possibility of calculation errors. It also greatly reduces the possibility of having too much or too little fiber to resin content, which can adversely affect the properties of the final composite layup. The technician simply lays out a pre-measured fiber reinforcement segment, mixes the pre-measured resin components (with the furnished mixing stick) and applies the resin to the reinforcement. No measuring is required in the field and performance tolerances are tightened with controlled fabric/matrix ratios. The material can be applied both circumferentially and helically along the pipe. Its low profile enables use in tight locations, within an inch of an obstruction in some cases.

PowerSleeve® has gone through numerous field trials, in-house testing, and third party testing. These tests have demonstrated that it possesses those performance qualities required for the repair of corrosion damage, both internal and external.
PowerSleeve® can be used to repair the following types of damage:
- External Corrosion (ASME PCC-2 Type A Repair)
- Internal Corrosion (ASME PCC-2 Type B Repair)
- External Mechanical Damage (dents, gouges, fretting, wear, etc.)
- External Coating Damage
- Internal Corrosion/Erosion
- Manufacturing or Fabrication Defects
- Leaks (if completely stopped prior to composite application)

The Standard Matrix is designed for general use. The system has good chemical resistance and structural properties and has a cure time of approximately 30-60 minutes at 77°F. This system has a Heat Distortion Temperature of 300°F for the W-11 fabric. Ships This ambient temperature cure matrix wets out easily and can be applied to our PowerSleeve® W-11 and G-03 Fabrics. It is relatively fast setting, approximately 30 minutes @77° F and is used where a maximum service temperature of 180° F is desired. No VOC's, 100% solids. This product ships DOT non-hazardous.
The 439 system is a medium temperature epoxy/novolac hybrid which cures at room temperature, yet has a much higher HDT than the Standard Matrix. The addition of novolac gives it better chemical resistance in cases where contact, whether external or internal, may occur. This system requires post cure in order to achieve the best chemical resistance properties. The HDT for the W-11 fabric is 425°F.. The matrix wets out easily and can be easily applied to our PowerSleeve® W-11 and G-03 Fabrics. This derivative of our 439 System allows for higher application temperatures. To achieve its ultimate properties, it requires heat in excess of 200° F during the curing process. It is relatively fast setting, approximately 45 minutes @150° F and is used where a maximum service temperature of 300° F is desired. Intermittent excursions to 325° F can also be tolerated. The color will change from a mild yellow to dark amber when temperatures rise above 150° F. This product ships DOT hazardous (corrosive).
70079 Matrix is a premium two-component, epoxy/novolac hybrid system with excellent exposure resistance to most military and civilian fuels and a vast array of chemicals, including sulfuric acid. It is also resistant to moisture and humidity effects. It contains no solvents, is 100% solids, and contains zero VOC's. This product is used as a composite matrix where its fuel and chemical performances are required. It is very resistant to moisture and humidity effects. It will cure in high humidity conditions. This product contains no solvents, is 100% solids, and contains zero VOC's. This product ships as non-hazardous.
The X-TEMP-2 system is designed for use where high service temperatures and harsh chemicals will be encountered. This system requires a minimum of 150°F to initiate the cure. It can be installed on temperatures up to 220°F, but special precautions need to be observed. This system requires post cure in order to achieve the best chemical resistance. This elevated temperature cure matrix wets out easily and can be applied to our PowerSleeve® W-11 and G-03 Fabrics. This system allows for higher application temperatures. To achieve its ultimate properties, it requires heat in excess of 450° F during the curing process. It is relatively fast setting, approximately 80 minutes @150° F and is used where a maximum service temperature of 525° F is desired. The color will be dark amber when temperatures rise above 200° F. This product ships DOT hazardous (corrosive).
