MANUFACTURED IN-PLACE COMPOSITE PIPE – (MICP) Remarkably unique… …. A novel device and method enters the marketplace that far exceeds the quality, versatility, environmental goodwill and worker safety of all competitive technologies, yet still affords reduced costs to it’s consumer ……. Manufactured In-place Composite Pipe (MICP) is a fully structural (Class IV) pressure pipe rehabilitation technology pursuant to the AWWA Close Fit Liner (CFL) classification. MICP was developed by Sipp. Tech and comprised of a robotically applied Sipp. Steel™ composite lining system. Sipp. Steel™ composite is comprised of of two disparate material layers and continuous, circumferentially wound and or axially applied fiber reinforcement. MICP is best suited for the long term structural renewal of deteriorated pressure pipelines however can be utilized on gravity systems. The Sipp. Tech robotic MICP installation system is capable of installing structural liners up to 2, 000 feet from a single access and can be programmed to line entire lengths of pipelines and or individual pipe sections in the access to access pipeline run. The robotics can negotiate and line up to 90 degree short radius bends and have the capability to install liner systems through existing accesses without the need for conventional access excavations. …… Sipp. Tech Is Remarkably Unique

MANUFACTURED IN-PLACE COMPOSITE PIPE – (MICP) Composite Layers Robotically Manufactured in Pipe: Ø Single Pass/Layer installation for small diameter and/or lower pressure systems. Ø Multiple Pass/Layer installation for large diameter and/or higher pressure systems. Ø Unlimited carbon fiber & rigid material layers & thicknesses for any resistance required for both internal and or external loading.
