We are designing a product to mount to expansion rings placed inside sewer pipe and i was looking for a few good sources for these rings. Any suggestions?
I don't have experience this subject but you might want to check some names/companies represented on committee ASTM C923, "Specification for Resilient Connectors Between Reinforced Concrete Manhole Structures, Pipes, and Laterals"
We will be putting a sensing instrument in pipes and using a metal band that expands along the interior circumference to hold it in place. I've found a few companies that sell them as part of a sensor package of their own but no places that offer them as a stand alone component
Look in the Trenchless Technology Mag or Website, trenchlessonline. A few people make an internal seal that is held in by expanding stainless rings. I want to say Creamer is one.
