C CRITICA

Unprocessed composite carbon epoxy resins for pressure containment, reinforcement, repair and rehabilitation of pipes, pipelines and vessels

Manually operated metal valves and manually operated metal line-stopping valves not being parts of machines which stop the flow of water or gas in water pipes, gas pipes, and petro-chemical pipes used for industrial purposes; valve systems comprised primarily of manually operated metal valves for use in water pipes, gas pipes, and petro-chemical pipes used for industrial purposes

Resin impregnated fiberglass anti-corrosion tape; Composite non-metal reinforcement and sealing compounds for the repair, reinforcement, or corrosion protection of pipes, ducts, storage tanks, or tubes; rubber and petrolatum anti-corrosion tapes for industrial or commercial use; non-permanent adhesive putty; Composite wrap composed primarily of bi-directional weave carbon fiber incorporating fiberglass hybrid fabric used to repair damaged pipes, structures such as bridges columns slaps, walls beams and joists, not for textile use; non-metallic adhesive bands of a curable resin matrix loaded with continuous high tensile strength filaments used for reinforcement, repair, protection and insulation of pipelines and other transporting and containment vessels, not for medical, household or stationery purposes

Reinforcing materials, not of metal, for building, namely, carbon-fiber fabrics used as structural reinforcement materials, namely, reinforcement fabrics for use in commercial and industrial construction for strengthening, stabilizing structures or civil infrastructure; construction and civil engineering material in the nature of non-metal, hybrid fiber/epoxy composite boards and panels used for retrofitting or repairing structures
