MECS® HexPro™ Ferrules

For waste heat boilers and heat exchangers in sulphuric acid plants. Precast, precision ceramic ferrules for severe temperature and heat-cycling conditions. Fast, Simple installation. MECS® HexPro™ Ferrules are pre-engineered for each installation and come properly sized, accurately molded, and completely wrapped with all required ber insulation. Installation is as simple as taking them out of the box and slipping them into the boiler tubes. No castable refractory is used between the MECS® HexPro™ Ferrules, and only the most minimal amount is required around the periphery. Operators can save days on turnaround without the need to painstakingly install, and then cure out, large expanses of castable refractory.

Consistent Properties
MECS® HexPro™ Ferrules are red under controlled conditions in a plant environment, resulting in consistent, predictable properties; rather than one that requires the extensive use of castable refractory and field curing. MECS® HexPro™ Ferrules are not subject to the vagaries of weather, installation expertise, and time constraints.

Operational Advantages
Thermal Management System (TMS) – a pre-red tubesheet protection system that allows for the extensive use of fiber insulation in conjunction with the MECS® HexPro™ Ferrules. In a greatly compressed area, TMS provides much better insulating value while saving space and refractory when compared to castable alone. Improved performance – Large expanses of castable refractory undergo tremendous thermal and mechanical stresses as they heat up and cool down and that generates cracking in the castable refractory. Tubesheet protection systems consisting of precast MECS® HexPro™ Ferrules perform as though they have built in expansion joints, which they do, limiting any damage due to these stresses to a conned area.
