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.
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. Qualification and design, installation, testing and inspection.

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

Installation Methodology for Compliant Composite Repairs. You may find similar items within these categories by selecting from the choices below:. By using this hybrid reinforcement sheet is conjunction with HLT and HT resins, the two-component system was expected to yield an optimized balance of mechanical strength, optimum adhesion and flexibility.
The repair was applied to specification and the pipe was pressurized up to Furthermore, the reinforcement sheet would be available in three different sizes to facilitate the application for the repair of piping elements exhibiting complex geometries such as tees, flanges and reducers among others. 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 isso This engineered system is an in-situ, cold cure alternative to gs cut and weld hot work and allows critical lines to stay in service.
The faster, easier way to work with standards. 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. In this regard, epoxies are superior to other non-metallic resins such as polyurethanemethacrylate, alkydvinyl, and polyester-based resins.
In ieo second articlewe’ll address how to provide compliant application of a two-part composite repair system, such as the one described here. 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. This value is then used to characterize the adhesion between the composite repair and the substrate.

Composite repair system compliant with ISO/TS
Testing details are summarized below. Mathematically, the value is also utilized for determining the minimum composite repair thickness required for applications onto through-walled substrates. Completed Belzona SuperWrap application. Several results worth mentioning are displayed as follows. Find Similar Items This product falls into the following categories. Reparatur von Rohrleitungen mit Verbundwerkstoffen.
Belzona Belzona Belzona More of your questions answered by our Experts. This demonstrated that the two-part composite repair had performed as designed. Suitable applications for this type of repair include large-diameter pipelines and components such as bends, flangesvalves, and reducers among others.
He has authored several technical articles and conference presentations. Thermal stresses cause metals to expand and contract when exposed to high and low temperature levels respectively.
As mentioned before, the growth in acceptance and usage of composite repair systems is inherently related to the availability of standardizing documentation. At around 42 MPa, the pipe clearly yielded, outside of the repair area.
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. Thermal expansion coefficient in solid materials describes how the size of a material changes with a change in temperature while the pressure is held constant. 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.
Carbon has the highest tensile modulus of all the above fabric types Kop, D. Composite repairs for pipework.
