From the Manufacturer This DERNORD Sanitary spools are made of stainless steel 304, they are prefabricated lengths of tubing with Tri Clamp fitting ends added for convenience. When combined with other Tri Clamp fittings, clamps, and gaskets, sanitary spools can build a process line without the need for on-site welding and fabrication, and at a considerable time savings. Tri Clamp spools also have the added benefit of being less permanent than welded tubing, and can be easily disassembled, moved, or reassembled in a different configuration. The versatility and cost savings of prefabricated spool pipe make them a popular solution for piping needs.
