DiamondWrap® HP™ for eroded and corroded pipelines
DiamondWrap® HP™ is engineered to provide strength that enables a pipeline 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 national laboratory level. The first component is a solid 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® HP™ system, is its bi-directionally woven carbon-fiber material, 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 (for example; heavy pitting), the high modulus filler putty can be applied.

DiamondWrap® HP™ was designed by Citadel Technologies to provide pipeline owners and operators with a cost effective solution and an alternative to repair clamps, welded sleeves and pipeline replacement.
Unlike fiberglass repair systems, DiamondWrap® HP™ offers reduced thickness solutions with higher strengths.
DiamondWrap® HP™ exhibits minimal creep and its stiffness approaches that of the steel.
Due to the flexibility of the design of the system and various kit options, DiamondWrap® HP™ can accommodate nearly any installation environment.
Limited excavation space and clearance only highlights the use of DiamondWrap® HP™, due to the simplistic installation procedure of the product.
DiamondWrap® HP™ can be installed on horizontal and vertical pipe with ease.
Damp conditions do not affect the product. Pipe temperatures can range from –20F to 180F for application of DiamondWrap® HP™.
For instances of severe pitting, Citadel Technologies has a proprietary epoxy based filler that can be pre applied so that loads are evenly transferred to the wrap system.
DiamondWrap® HP™ kits
All materials specified in an engineering assessment come to the job site precut to length and packaged in pre-measured containers.
Citadel Technologies QC program ensures that kits arrive with all the materials necessary to complete the job. No additional tools are required.
DiamondWrap® HP™ is compliant to DOT regulation, ASME B31, .8, .4, .G and PCC-2 Art 4.1, 4.2 and API 570.
Please refer to API 570, Section 8.1.4 – Non-welding Repairs (On-Stream)
Maximum Pipeline Strength
basic DIAMONDWRAP® HP™ iNSTALLATION
Prep Surface - usually sandblasting bare steel and brush-off blast or sweep blast exisiting coatings
Epoxy Putty - apply CMF epoxy putty on deformations or heavy pitting areas of the pipeline repair area
Epoxy Primer - prime area to be repaired plus an additional two inches on either side of the total repair
Wet-Out Epoxy - apply wet-out epoxy to completely cover the carbon fiber wrap, using included roller
Carbon Fiber - install carbon fiber on to the pipe surface as outlined in the accompanying paperwork
Tend & Check - tend the wrap to make sure no bubbles are present and fiber is not drooping or wrinkled
DIAMONDWRAP® HP™ & leak repair
DIAMONDWRAP® HP™ SYSTEM IS DESIGNED FOR INSTALLATION ON TRANSMISSON PIPELINES. DIAMONDWRAP® HP™ SYSTEM IS NOT INTENDED FOR USE ON A PIPELINE LEAK REPAIR. LEAK REPAIR SHOULD BE CONDUCTED USING THE DIAMONDWRAP® LINE OF PRODUCTS.
