Reference # : Model No :

AcidShield™ is a custom engineered composite repair system with superior chemical compatibility. AcidShield™ is designed for repairing corroded and damaged piping, this ASME PCC-2 4.1,4.2 compliant system uses chemically resistant, bi-directional fabric in conjunction with a proprietary epoxy system to deliver repairs suitable for piping with harsh chemical services, including 98% sulfuric acid at temperatures up to 150°F (66°C). AcidShield™ is a breakthrough with regard to its compatibility with H2SO4 at 98% concentration as it is the first composite repair system fully tested and proven to be resistant at such a level.

Benefits

•AcidShield™ eliminates unplanned down time for high-consequence piping
•Extends the life of aging and corroding assets
•No pipe cutting or welding
•Prevents future corrosion
•Qualified and compatible with 98% sulfuric acid up to 150°F (66°C)
