Techno-wraps used for Offshore Piping protection

Hello All, I'm looking for technical information on Techno-wraps used for Offshore Piping protection. We have a couple of leaking or near failure crude pipelines that we thought we couple clamped, but a vendor brought in the techno-wrap material and says it could pass for similar protection application. I'm sceptical about the information and pressure limits. I would like some understandings of the materials from whoever has prior experience. Thanks
