In his role as Oil and Gas Manager, he works with Belzona colleagues, asset owners, engineering firms, contractors, and fabricators in the oil and gas industry across all of the Americas. These sheets are typically made of carbon, glass fibers or a combination of both. January Replaced By: Epoxy phenol Novolac resins also form isl cross-linked matrices that display high temperature and chemical resistance.

The repair was applied to specification and the pipe was pressurized up to While both standards supply extensive information and guidance on how to design, apply, test and inspect composite repairs systems, there are certain differences in calculation engines and considerations.

Completed Belzona SuperWrap application.

Composite repair offers an affordable alternative to the costly replacement of piping and pressurized equipment that have been severely damaged by corrosion or years of use. At around 42 MPa, the pipe clearly yielded, outside of the repair area.

Hence, any composite repair used to restore mechanical strength to a pressurized pipe system must 24871 able to cope with these stresses in similar ways to the pipe itself.

After carefully considering the benefits and drawbacks of each fabric, it was decided to use a 224817 of carbon and glass reinforcement fibers woven together. By using this hybrid reinforcement sheet in conjunction with HLT and HT resins, the two-component system was expected to yield an optimized balance of mechanical strength, optimum tz and flexibility.

Designing & Testing a New ISO/ASTM-Compliant Composite Repair Solution

Because epoxy-based resins tend to cure slowly or very quickly at low and high temperature levels respectively, two types of resins were designed, as shown in Table 1. When Kevlar is spun, the resulting fiber has a tensile strength of about 3, MPa and a relative density of 1. Kso demonstrated that the two-part composite repair had performed as designed. Because the composite repair system must form a bond with the damaged substrate, it relies on the tz quality of the resin for some of its strength.

To get the best possible experience using our site we recommend that you upgrade to a modern web browser.

Qualification of such systems is required tw compliant application onto pipework. In recent years, composite repairs have been gaining greater acceptance among asset owners and equipment operators—not only because these repairs provide an engineered, durable and affordable alternative to replacement, but also because they comply with international engineering standards.

Search all products by. Dyneema has yield strengths as high as 2.

Composite repair system compliant with ISO/TS

Composite repairs for pipework. X Did you know that your Internet Explorer is out of date? With respect to CUI, how well do thermal insulating coatings retard the spread of corrosion? Pressure was then increased to determine where a yielding would occur, whether in the repair or in the original pipe. We don’t display the email address publicly, but this page will go to the organization’s information that we have on file.


Written by Osmay Oharriz, Ch. However, a combination of glass fiber and carbon reinforcement provides mechanical strength while delivering a certain degree of flexibility for better long-term thermal cycling performance. For info on how we work with industry partners click here. Also, experience has shown that an elastic modulus of at least 6, MPa is a good benchmark for predicting the in-situ performance of a composite repair Alex.

Hence, any composite repair used to restore mechanical strength to metallic substrates must be able to cope with thermal stresses in the same or a similar way to the substrate itself.

Glass, on the other hand, is easy to cut, transparent and fairly inexpensive. Pipe wrap system to repair damaged pipework Compliant patch repairs for tanks, vessels and pipelines Long term, through wall and thin wall defect repairs for complex geometries including bends, tees, reducers and flanges Restoring strength to damaged pipework Reinstating integrity to heavily pitted or corroded surfaces Internal or external corrosion protection This hs system is an in-situ, cold cure alternative to traditional cut and weld hot work and allows critical lines to stay in service.

These compliant composite repairs rely not only on a pre-qualified material and pre-defined mathematical design, but also on competent application craftsmanship.
