The document discusses circular flange UF pipe connections. It can compensate for large diameter tolerances through the telescope technique. It is used to connect longitudinal and spiral seamed round pipes. Sealant is injected into the profile ring to attain a class C seal. Pipe diameters range from 200-3000mm. Various sizes are listed with their dimensions, materials, pipe diameters, packaging quantities, and weights. Workmanship involves injecting sealant while rotating and inserting the pipe into the flange, which can then be secured through spot welding, riveting, or self-drilling screws. It is applicable to folded spiral-seam and longitudinal seam pipes.
