Pipe Flanges Rating in Different Norms

There were a lot of flanges standards in the world, DIN, EN1092-1, BS4504, ANSI, AWWA, UNI, JIS, SANS, GOST, NFE, ISO, AS, NS etc, even every country have their owned norms for pipe flanges, but in fact, the flanges norms can be separated to American norms and European Norms, the American norms have ANSI, API, AWWA, MSS etc norms for flanges, their rating use “LBS”, for example 75lbs, 150lbs, 300lbs, 600lbs, 900lbs, 1500lbs, 2500lbs etc, but for European norms, like DIN, EN1092-1, BS4504, UNI etc, the rating USE “PN”, for example PN6, PN10, PN16, PN25, PN40, PN63, PN64, PN100 etc, also for the Russian flanges of GOST 12820 and GOST 12821, they are similar to European norms, but use PNxx mPa, for example, PN0.6MPA, PN1.0MPA, PN1.6MPA, PN2.5MPA, PN4.0MPA. In africa, the main flanges standard is SANS1123 or SABS1123, it is South African norm, its rating is for 600kpa, 1000kpa, 1600kpa, 2500kpa, 4000kpa etc, also similar to European Norms, In China, before time, Chinese flanges are similar to CCCP, but recently years, Chinese flanges norms revised to European system, also use PN6-PN100 rating. The flanges ratings are very important for flanges application, correct flanges rating will keep the application safe.

What is “PED”

Pressure equipment and gas appliances

Pressure Equipment Directive (PED):

The Pressure Equipment Directive (97/23/EC) was adopted by the European Parliament and the European Council in May 1997. It has initially come into force on 29 November 1999. From that date until 29 May 2002 manufacturers had a choice between applying the pressure equipment directive or continuing with the application of the existing national legislation. From 30 May 2002 the pressure equipment directive is obligatory throughout the EU.
The directive provides, together with the directives related to simple pressure vessels (2009/105/EC), transportable pressure equipment (99/36/EC) and Aerosol Dispensers (75/324/EEC), for an adequate legislative framework on European level for equipment subject to a pressure hazard.

The PED Directive pdfбългарски (bg)czech (cs)dansk (da)Deutsch (de)eesti (et)ελληνικά (el)español (es)Français (fr)Gaeilge (ga)italiano (it)latviešu (lv)lietuvių (lt)magyar (hu)Malti (mt)Nederlands (nl)polski (pl)português (pt)română (ro)slovenčina (sk)slovenščina (sl)suomi (fi)svenska (sv) arises from the European Community’s Programme for the elimination of technical barriers to trade and is formulated under the “New Approach to Technical Harmonisation and Standards”. Its purpose is to harmonise national laws of Member States regarding the design, manufacture, testing and conformity assessment of pressure equipment and assemblies of pressure equipment. It therefore aims to ensure the free placing on the market and putting into service of the equipment within the European Union and the European Economic Area. Formulated under the New Approach the directive provides for a flexible regulatory environment that does not impose any detailed technical solution. This approach allows European industry to develop new techniques thereby increasing international competitiveness. The pressure equipment directive is one of a series of technical harmonisation directives for machinery, electrical equipment, medical devices, simple pressure vessels, gas appliances etc.

The Directive concerns items such as vessels, pressurised storage containers, heat exchangers, steam generators, boilers, industrial piping, safety devices and pressure accessories. Such pressure equipment is widely used in the process industries (oil & gas, chemical, pharmaceutical, plastics and rubber and the food and beverage industry), high temperature process industry (glass, paper and board), energy production and in the supply of utilities, heating, air conditioning and gas storage and transportation.

Under the Community regime of the Directive, pressure equipment and assemblies above specified pressure and/or volume thresholds must:

  • be safe;
  • meet essential safety requirements covering design, manufacture and testing;
  • satisfy appropriate conformity assessment procedures; and
  • carry the CE marking and other information.

Pressure equipment and assemblies below the specified pressure / volume thresholds must:

  • be safe;
  • be designed and manufactured in accordance with the sound engineering practice of a Member State; and
  • bear specified markings (but not the CE marking).

The ASME B16.5 – 1996 Pipe Flanges and Flange Fittings standard covers pressure-temperature ratings, materials, dimensions, tolerances, marking, testing, and methods of designating openings for pipe flanges and flanged fittings.

The standard includes flanges with rating class designations 150, 300, 400, 600, 900, 1500, and 2500 in sizes NPS 1/2 through NPS 24, with requirements given in both metric and U.S units. The Standard is limited to flanges and flanged fittings made from cast or forged materials, and blind flanges and certain reducing flanges made from cast, forged, or plate materials. Also included in this Standard are requirements and recommendations regarding flange bolting, flange gaskets, and flange joints.
