General description Low Friction Insulated U-Bolt and Backing Pad for Standard Schedule Pipe 29 mm ID (suitable for 20 mm NB pipe) is designed to securely guide pipes while minimizing friction. This innovative solution safeguards pipes from wear due to temperature-induced expansion and contraction, while also reducing noise and vibration. The unique design features a gap between the U-bolt and the pipe, allowing for unrestricted movement while maintaining proper guidance. Technical specifications U-Bolt material: Galvanised mild steel Pipe O/D: 26.9 mm NB: 20 mm A: 29 mm B: 43 mm C: 70 mm D: 6 mm E: 64 mm F: 65 mm G: 14 mm H*T (backing pad): 25*10 mm Tolerance on dimensions: +/- 1 mm Backing pad material: Neoprene Rubber Elastomer: Neoprene Colour: Black Quality: Commercial Grade: C20 Hardness: 65 shore A +/-5 S.G.: 1.4 G/Cm3 Tensile MPA: 5 MIN Elongation: 300% Tear Strength: 20 Kg/CM Compression Set: 35% Operating Temperature: -20 / +110 °C Other information Protected by U.K Patent
