You may experience issues viewing this site in Internet Explorer 9, 10 or Epoxy phenol Novolac resins also form highly cross-linked matrices that display high temperature and chemical resistance.

A repair was then engineered to restore the pipe to this original pressure. This is factual evidence that not only had the composite repair returned the pipe to its original strength, but it had also made the defect area stronger than the original pipe section. 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.

Belzona SuperWrap being applied.

Based on epoxy resins and performance enhancing fillers in combination with high density treated glass fibre reinforcement, Belzona SuperWrap offers a long-term alternative to replacing defective steelwork. Testing details are summarized below. Search all products by.

With respect to CUI, how well do thermal insulating coatings retard the spread of corrosion? Dyneema has yield strengths as high as 2.


ISO/TS 24817:2006

When Kevlar is spun, the resulting fiber has a tensile strength of about 3, MPa and a relative density of 1. Such a combination provided superior adhesion and 2817 strength when compared to other functional polymeric groups such as polyurethane, methacrylate, alkyd, vinyl and polyesters. 248177 you for contacting us. Kevlar is a registered trademark for a specific type of aramid synthetic fibers. Because the composite repair system must form a bond with the damaged substrate, it relies on the adhesive quality of the resin for some of its strength.

Qualification and design, installation, testing and inspection Status: To download a newer web browser click on the Upgrade button. In a second articlewe’ll address how to provide compliant application of a two-part composite repair system, such as the one described here.

Suitable applications for this type of repair include large-diameter pipelines and components such as bends, flangesvalves, and reducers among others.

Carbon reinforcement sheets are costly, more rigid, and difficult to cut, design and apply in comparison with glass fiber reinforcement. This cold cure solution has been developed as a compliant pipe wrap or patch repair to return strength to weakened or holed metallic surfaces and provides excellent corrosion protection and chemical resistance. Are there CUI concerns for operating temperatures over degrees F? 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.

Composite repair system compliant with ISO/TS

2817 Learn more about the cookies we use and how to change your settings. 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. Pressure was then increased to determine where a yielding would occur, whether in the repair or in the original pipe.


Petroleum, petrochemical and natural gas industries. 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.

This value is then used to characterize the adhesion between the composite repair and the substrate. We use cookies to make our website easier to use and to better understand your needs.

Belzona SuperWrap application in progress. Flange joint encapsulated with Belzona SuperWrap. An Overview of Alkyd Resins. Click to learn more. This means that such a composite repair will react similarly to the carbon steel substrate onto which it is applied upon compression or tension loads.

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.
