Ratings of Flanged Joints-manufacture,factory,supplier from China

This St andard covers pressure–t emperature  ratings, materials, dimensions, tolerances, marking, testing, and methods of designat ing openings for pipe  flanges and flanged fittings. Included are                                             Production Process:Our group:Jinan Jiang Hua Forging Machinery Co.,Ltd was established in 1995.

In BS EN 1092-1:2007, the materials and material groups used in the manufacture of flanges are given in Table 9 and their corresponding.Pressure/Temperature ratings are given in Annex G (normative). Additional materials that are widely in used in Europe are listed in Annex D (informative) but BS EN 1092-1:2007 contains no corresponding Pressure/Temperature information for these materials. National Annex NA (informative) contains guidance on Pressure/Temperature ratings for materials S235JR/1.0038 and ASME SA 105, which are predominantly used in the UK.1. Standard:EN1092-1 2.

Pressure–temperature ratings are maximum allowable working gage pressures in bar units at the temperatures in degrees Celsius shown in Tables 2-1.1 through  2-3.19 for the applicable material and class designation.  Tables II-2-1.1 through II-2-3.19 of Mandatory  Appendix II list pressure–temperature ratings using psi  units for pressure at the t emperature in degrees  Fahrenheit. For intermediate temperatures, linear interpolation is permitted. Interpolation between class designations is not permitted.  

The p/T ratings of this standard have been reduced in many cases by either limiting the lowertemperature ratings which can no longer exceed the PN value, or by increasing the rate at which allowable pressures shall reduce with increase in temperature;2) in addition to the range of PN 2,5 to PN 40 DIN origin flanges contained in the ISO standard, EN 1092-1 also includes flanges up to PN 400.1.

A blind flange is a solid flange as shown below. The purpose of these is to block off a section ofpipe or a nozzle on a vessel that is not used. (A nozzle is typically a pipe coming out of a vessel and is usually flanged so it can be connected to valves or piping). Many times a nozzle will be blanked off with a blind flange for pressure tests in a plant, or simply because the customer does not need all the nozzles that were supplied on the tank.1.
