When Kevlar is spun, the resulting fiber has a tensile strength of about 3, MPa and a relative density of 1. Completed Belzona SuperWrap application. Search all products by. On the other hand, the ASME standard does not explicitly consider the repair expected lifetime in the design equations.

At around 42 MPa, the pipe clearly yielded, outside of the repair area. Flange joint encapsulated with Belzona SuperWrap. 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. 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.

You may experience issues viewing this site in Internet Explorer 9, 10 or The repair was applied to specification and the pipe was pressurized up to Polyester was found to be very flexible and of low density, but it had the lowest tensile strength and modulus of all the aforementioned fibers. 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.

Composite repair system compliant with ISO/TS

Thank you for contacting us. 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.


The yield pressure of the undamaged spool was calculated to be The Corrosion of Polymeric Materials. 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 engineered system is an in-situ, cold cure alternative to traditional cut and weld hot work and allows critical lines to stay in service.

For others, actual carbon steel spools of known dimensions and specific defects were repaired in accordance to ISO requirements. Find Similar Items This product falls into the following categories. More of your questions answered by our Experts.

DD CEN ISO/TS 24817:2011

This cold cure solution has been developed as a compliant pipe wrap or patch repair to return strength to weakened or 2487 metallic surfaces and provides excellent corrosion protection and chemical resistance. After carefully considering the benefits and drawbacks of each fabric, it was decided to use a hybrid of carbon and glass reinforcement fibers woven together.

Petroleum, petrochemical and natural gas industries. 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.

Kevlar is 2817 registered trademark for a specific type of aramid synthetic fibers.

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. Epoxy phenol Novolac resins also form highly cross-linked matrices that display high temperature and chemical resistance.

Several results worth mentioning are displayed as follows. He has authored several technical articles and conference presentations. This demonstrated that the two-part composite repair had performed as designed. Mathematically, the value is also utilized for determining the minimum composite repair thickness required for applications onto through-walled substrates.


In this regard, epoxies are superior to other non-metallic resins such as polyurethanemethacrylate, alkydvinyl, and polyester-based isk. However, Kevlar requires special cutting tools and it was not found to be as strong as carbon fibers.

The use of two types of resins facilitates application of the composite system in different environmental conditions:. Where can I find a coating that is chloride and sulfur corrosion-resistant? Learn about various ways to measure strength in the article 6 Tests to Measure a Material’s Strength. Written by Osmay Oharriz, Ch.

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 adhesion and flexibility. This is a Belzona 2487 Distributor.

January Replaced By: Carbon has the highest tensile modulus of all the above fabric types Kop, D. For More Information regarding Belzona Products, please login by clicking here. Installation Methodology for Compliant Composite Repairs. For some tests, composite slabs were prepared using LT and HT resins reinforced with three wraps of resin-wetted reinforcement.

Please download Chrome or Firefox or view our browser tips. Two-part component composite repair systems typically comprise a resin material and a reinforcement sheet that can be tailored for application onto pipeline, pipework and vessels in pressurized services.

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

Worldwide Standards We can source any standard from anywhere in the world. Internally generated circumferential stresses tend to cause the pipe to slightly increase in diameter while becoming shorter. Belzona Belzona Belzona Pressure 24187 then increased to determine where a yielding would occur, whether in the repair or in the original pipe.
