General description Low Friction Insulated U-Bolt and Backing Pad for Standard Schedule Pipe 57 mm ID (suitable for 40 mm NB pipe) is designed to securely guide pipes while minimizing friction. This innovative solution safeguards pipes from wear due to temperature changes and reduces noise and vibration during fluid transport. The unique design features a gap between the U-bolt and the pipe, allowing for expansion and contraction while maintaining guidance. Technical specifications U-Bolt Material: Zinc Plated Mild Steel Pipe O/D: 48.3 mm NB: 40 mm A: 57 mm B: 75 mm C: 100 mm D: 10 mm E: 76 mm F: 80 mm G: 24 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 Number 2 557
