How to Repair a Pipe with a Compliant Engineered Composite Wrap

Learn how to repair a pipe using Belzona SuperWrap II, a composite wrap system for repairing and reinforcing damaged pipework. This step-by-step guide demonstrates a composite pipe repair, providing a cold-applied solution for damaged and corroded industrial pipework.

In this application, Belzona 1511 (Super HT-Metal) is used to bond a composite pad over the through-wall defect before Belzona SuperWrap II is applied using Belzona 1983 resin and Belzona 9341 (Reinforcement Sheet).

Frequently asked questions

A damaged pipe can be reinforced using an engineered composite repair system such as Belzona SuperWrap II. In this application, a composite pad is first bonded over the through-wall defect using Belzona 1511, followed by multiple layers of Belzona SuperWrap II reinforcement wetted with Belzona 1983 resin. The repair is then consolidated with Belzona 9382 release film before curing.

Yes. Belzona SuperWrap II provides a cold-applied composite repair option for through-wall and thin-wall pipe defects without the need for welding or other hot work. This can make it particularly suitable for industrial environments where welding is difficult, undesirable or presents additional safety requirements.

Belzona SuperWrap II can be engineered, designed and applied in accordance with ISO 24817 and ASME PCC-2, internationally recognised standards for composite repairs to pipework and pressure equipment. Compliant repairs require the appropriate engineering design and application by trained and validated personnel.

The repair demonstrated uses Belzona 1511 (Super HT-Metal) to bond the composite pad over the pipe defect, followed by Belzona 1983 resin and the SuperWrap reinforcement sheet to form the engineered composite wrap. Belzona 9382 release film is then applied to consolidate the repair during curing.

Belzona SuperWrap II can be used to reinforce pipework affected by corrosion, wall thinning and through-wall defects. Engineered composite repairs can also be designed for a range of pipe geometries, including straight pipe sections, bends and tees, depending on the defect, operating conditions and engineering requirements.
