Two piece Split Casing can go from 10" all the way up to 144" with our current capabilities. Installation of either is pretty much the same with the main exception being size and weight. Larger sizes come equipped with convenient tabs heavy equipment can hook onto for ease of installation. You might glean some ideas from a photo-gallery of shots we've been able to acquire but here's the basics.
The FMP Split Casing system is shipped in 10 ft. halves with anti-corrosive fasteners included, configured according to the flange bolting slot pattern indicated below (holes positioned on-center to allow field customization). Half sections can be ordered pre-cut into 5 ft. sections to enable staggered assembly, creating strength and eliminating the need for coupling in straight runs. Labor savings of 50 - 75% have been reported from field installers.
Ironhed FMP is installed using overlapped or staggered joint assembly.
No couplers are required for straight runs.
