Repair pipes and tanks with this composite technology
Belzona Polymerics
The Belzona SuperWrap II pipe-wrap repair system (photo) combines a cold-curing, fluid-grade epoxy resin and a hybrid reinforcement sheet consisting of glass and carbon fibers.The glass fibers provide sheet flexibility, while the carbon fibers give the applied composite the strength needed to withstand high pressures and mechanical loading. Two different resins are available (to accommodate different service temperatures). This product has recently undergone additional reformulation enhancements, to build upon and expand the performance of the predecessor product. The composite-repair method restores strength to weakened or perforated metallic substrates without the need for hot work or lengthy downtime, says the company. This product has achieved compliance with a variety of key industry standards, including ISO 24817 (Composite Repairs for Pipework) and ASME PCC-2 Article 4.1 (Non-metallic Composite Repair Systems for High-Risk Applications). It is particularly well-suited for complex geometries that include bends, straights and tees, and can also be applied as a patch repair to large pipes (over 600-mm dia.) and tank walls. It uses a simple, two-part epoxy resin system and provides a 20-year design life (in accordance with ISO 24817). — Belzona Polymerics Ltd., Harrogate, U.K.
