'Bishop Adamant Gauge Glass Tubing' in a wide range of diameters and wall thicknesses in Borosilicate material which is highly resistant to water, neutral and acidic solutions, concentrated acids, and organic solutions. For smaller diameters (up to 38mm or 1.12") the composition has been developed specifically to cater for the requirements of gauge glasses used in high pressure steam boilers, for both temperature and chemical resistance. Red striped glass tubes are available for use in low pressure level gauges’ Larger diameters are used as sight flow indicators in pipelines, chemical process plants, and other process equipment. Glass rods in borosilicate and soda glass rods and tubing are available for special applications. Specifications: Diameters from 6mm to 300mm End Finish: Ground, Fused, Polished, or as Cut Lengths: Generally 1500mm but lengths of 3000mm (120”) in Specific Diameters Maximum Temperature: Generally 450° C or 220° C for Steam Application Thermal Shock: 160° C Refractive Index: 1.473 Coefficient of Expansion: 3.2 x 10-6 Deg K
