• Easy Installation:The flexibility allows to effectively protect circular pipe,elbows and risers.
• Saves Time & Money: No special priming or operator equipment is required, product installation is quick and labour costs are kept to a minimum.
• Long Term Protection: It is manufactured using materials that provide high electrical resistivity, low water absorption and low moisture permeability.
