27、ng conditions 4.1 Material properties The glass parts referred to in this specification shall be manufactured from borosilicate glass 3.3, which is resistant to both heat and chemical attack. Its properties are specified in ISO 3585. 4.2 Working conditions The maximum allowable temperatures and pres

28、sures of installed systems shall not exceed those recommended by the manufacturer. There may be further limits, such as temperature differences and rates of heating and cooling, where reference shall be made to the manufacturers recommendations. 5 Basic dimensions 5.1 Nominal sizes (DN) The nominal

29、sizes DN are: 15, 25, 40, 50, 80, 100, 150, 200, 225, 300, 400, 450, 600, 800, 1 000. 5.2 Length All lengths of pipe sections size DN 15 to 150 shall be dimensioned in multiples of 25 mm. The length L: of components with plain buttress ends is the distance between the joint faces (see Figure 1); of

30、components with spherical buttress ends is the distance between the diameters d 0 (see Figure 2). 5.3 Wall thickness The required wall thicknesses shall be determined in accordance with EN 1595. 6 Mating requirements 6.1 Components with plain and spherical buttress ends In order to ensure the compat

31、ibility of components with plain and spherical buttress ends, the dimensions given in Table 1 shall be adhered to. 6.2 Adaptor flanges Because of the availability of glass components with different buttress end forms, backing flanges supplied by manufacturers of glass plant differ in shape, pitch ci

32、rcle diameter and number and diameter of bolt holes. To ensure that these various forms of buttress end can be bolted together, an adaptor flange shall be used. 6.3 Gaskets For sealing between spherical buttress ends of different shapes, the gasket for the concave buttress end shall be used. For pla

33、in buttress ends a gasket with a diameter within the annular mating zone shall be used (see Figure 1 and Table 1). Where one of the buttress ends has a gasket location groove the gasket appropriate to the grooved buttress end shall be used.Page 4 EN 12585:1998 BSI 09-1999 Table 1 Dimensions for comp
