DIAMONDWRAP is the premier carbon fiber wrap system used to rehabilitate and restore original operational strength to damaged, corroded and eroded piping systems. DIAMONDWRAP is engineered to provide strength that enables a pipe to be restored to maximum allowable operating pressure (MAOP) without shutting down. The system is comprised of three components, each thoroughly and independently tested at both the university and international laboratory level. The first component is an epoxy primer, which ensures complete bonding and load transfer between the repair and the substrate. The second component and most unique feature of the DIAMONDWRAP system, is its selection of bi-directional woven carbon-fiber materials, which provides reinforcement in the hoop and axial directions and is the strongest available non-metallic repair on the market. The third part of the binding force in the system is the polymeric epoxy resin, which allows for uniform loading throughout the entire wrap. For repairs that require surfaces to be modified (e.g.: heavy pitting or irregular shapes), the high modulus filler can be applied. These components form a composite system that is stronger than steel. The structural system forms a pipe around a pipe, and each successive wrap increases the pressure rating. Minimal creep ensures a long service life.

DIAMONDWRAP requires an engineering assessment to compile service information such as substrate material, wall loss, operating temperature, pressure ranges and environment exposure. Citadel Technologies DIAMONDWRAP Wizard software analyzes this information to determine the number of wraps required for each pipe repair.

Because of its wet lay-up and low profile, DIAMONDWRAP can be installed on tees, elbows and straight runs of pipe. It also works well in confined spaces and on irregular surfaces that require structural reinforcement or leak containment.

DESCRIPTION

DIAMAFORCE is the premier carbon fiber reinforced polymer (CFRP) laminate designed for strengthening concrete, steel and masonry structures. DIAMAFORCE bonds to compromised structures as external reinforcement using Citadel Technologies high quality blend of two part epoxies.

DIAMAFORCE integrates proprietary products with specialty engineering services to improve, protect, and enhance infrastructure. DIAMAFORCE repairs deterioration or damage and enhances structures in order to extend life or comply with change of use requirements. For new construction, DIAMAFORCE improves the performance, protects and extends the life of structures, as well as corrects construction defects.

DIAMAFORCE can be used to increase the strength of existing beams, slabs, walls, columns and connections. Building strengthening applications typically include seismic retrofit; strengthening due to corrosion, change of use, or in some cases, the correction of an existing defect due to a construction or design error.

DIAMAFORCE is ideal for industrial structure strengthening because of its high strength-to-weight ratio and ease of installation. DIAMAFORCE can be installed with minimal impact to the operations of the structure and is easily installed around existing equipment and instrumentation. DIAMAFORCE can be used to encapsulate, seal and protect other repairs.

There are many drivers for increasing or restoring the structural capacity of structures, including code changes, changes in use (which increase service loads), deficiencies within the structure caused by errors in design or construction, or loss of capacity due to deterioration. Regardless of the need, DIAMAFORCE and Citadel Technologies can assist in the development and implementation of value-added structural upgrade and strengthening solutions.

RHINOWRAP is a hybrid carbon fiber and fiberglass composite wrap system used to rehabilitate and restore strength to low pressure, low risk corroded and eroded piping systems. RHINOWRAP is engineered to provide strength that enables a pipe to be restored to normal operating pressure without shutting down.

The system is comprised of two components, each thoroughly and independently tested at both the university and national laboratory levels. The first component and most unique feature of the RHINOWRAP system, is its hybrid bi-directionally woven carbon/fiberglass material, which provides reinforcement in the hoop and axial directions and is the strongest low risk non-metallic repair on the market. The second component of the binding force in the system is the polymeric epoxy resin, which allows for uniform loading throughout the entire wrap.

As a flexible wet lay-up system, RHINOWRAP can be installed on tees, elbows, and straight runs of pipe. This flexible system is also easily applied in confined spaces and on irregular surfaces that require structural reinforcement or leak containment. The adhesive properties of the epoxy allow it to be applied to most substrates. Each kit is designed to cover a specific square footage amount with 4 options of cloth width.

SLS-30 is a two-component, 100% solids, no VOC epoxy system. It has been designed to provide the greatest structural strength and chemical resistance of any product in its class.

SLS-30 provides both a structural, cured-in-place lining and a chemical protective barrier in one quick application. It can be applied to both old and new bricks, concrete and steel at a thickness of 40 mls. to over 275 mils.

SLS-30 can be applied at all ambient temperature ranges; however, care must be taken not to apply over frost or active leaks. It must also be noted that when applied to very cold surfaces, set and cure times will be greatly increased. As with any cured in-place system that requires a good bond, the substrate must be free from all dirt, oil, grease, and rust.

Failure Pressure

Fatigue tests were performed by the University of Tulsa on pressure vessels to determine the effectiveness of repairs made using a carbon/epoxy composite material system. The carbon/epoxy system is intended to repair externally damaged or corroded steel pipe. Six-inch nominal diameters by five feet long pressure vessels were constructed from A-106 Grade B steel for test purposes. Defects were machined into the outer surface of each pressure vessel to determine limitations of the carbon /epoxy repair system. Unrepaired pipes were cycled to determine a base number of maximum operating cycles. Remaining vessels were wrapped and then cyclically pressurized until a leak in the system was detected. The repaired vessels were compared to un-repaired vessels with equal size defects to determine the effectiveness of the repair. Results indicate there was a substantial increase in the performance of the pipe.

The University of Tulsa performed cathodic disbondment testing. Cathodic disbondment tests were conducted on A-106 Grade B steel pipes on which carbon- fiber-reinforced polymeric wraps were installed. The composite wraps are part of system used to repair externally damaged or corroded steel pipes. To stimulate a corrosive environment, pipes coated with the composite wraps were submerged in an electrolyte consisting of potable water, sodium chloride, sodium sulfate and sodium carbonate. Holidays or breaks in the composite wrap were produced, exposing electrolyte. Test results indicate the carbon-fiber-reinforced polymeric repair system exhibits no disbondment.

Galvanic Corrosion tests were performed by the University of Tulsa using composite panels joined in conjunction with dissimilar metals. The test results showed no corrosion attributed to Galvanic Corrosion.

Room temperature, coupon testing was performed at the University of Tulsa. Specimens were tested using an in-situ creepture fixture. The test was done at 77% (UTS), and the results were recorded for a 1350-hour test period. The creep testing supports the fact that carbon-fiber composites are resistant to creep and creep rupture under ambient conditions. The level of creep in the tests was small enough to extrapolate that the material would not fail at 77% (UTS) load during its lifetime.

Citadel Technologies standard epoxy is designed for operating temperatures up to 82C (180F). This system is blended to withstand a wide range of chemicals including: caustic, 20% sulfuric acid, 20% hydrochloric acid, water, brine, detergents, toluene, gasoline, and other weak acids and solvents. It is not intended for concentrated Strong Acids, Organic Acids, Strong Solvents (MEK, Acetone, Alcohol). For these stronger chemical concentrations, please consult Citadel Technologies and consider the use of Citadel Technologies Acid epoxy system.


Tests involving dents and gouges were performed both by the University of Tulsa and by Stress Engineering. The results of this test program, along with supporting data from other studies on these repair systems, confirm the validity of this repair system for repair of dents and pipes with gouges. The reinforcement provided by the carbon fiber/epoxy composite repair system provides a significant increase to the fatigue life of un-repaired mechanically damaged pipes.

Composite Repairs Made While The Pipe is Pressurized

Testing was conducted on Citadel Technologies carbon composite products by wrapping defective pipe while under internal pressure loading. Test pipes with flaws varying from 20% to 75% wall loss were wrapped while the pipe was operating at MAOP. The pipes were then cycled between 50 PSI and MAOP. After inspection indicated that there was no de-lamination, the pipes were pressured to rupture. No differences were noted to those pipes that were wrapped at zero pressure. This testing shows that defects may be repaired without reducing the pipeline pressure prior to wrapping.

If you would like more detailed information regarding these, or other, test programs, please contact Citadel Technologies and request a copy of the Citadel Technologies Technical Product Guide.

Citadel Technologies epoxy products have a minimum shelf life of more than two (2) years when stored in a dry place at room temperature and sealed in the original unopened container.

BlackDiamond System stored over 5 years has been tested with no measurable change in characteristics.

Typically stabilizing the resin system temperature between 20C and 30C (68F -86F) is recommended. This provides the best viscosities and pot life for ease of installation. Note that some environmental and operating conditions and temperatures can change this recommendation. Our engineering staff will provide you with any recommended changes.

The epoxy systems are 100% solids. Each system is manufactured for specific applications for installation on systems where hydrocarbons and high operating temperatures are a critical factor.
