Flanged Maintenance Pipe (FMP) was initially developed as a split steel conduit to protect communication cables in crowded easements from damage due to future excavations. From the original IPS conduit sizes, FMP is now offered from 1 ½” to 6” in a variety of materials and wall thicknesses to address many applications including bridgework and heavy civil construction projects such as rail and highway. (Also available as Split Casing in sizes up to 144"). FMP’s simple design and installation saves labor and preserves timelines. Ironhed LLC works closely with project engineering firms to craft split conduit solutions to be designed specifically for individual project needs – and we would welcome your call.
