About Flanges Rating PN64 and PN63

Any one who noted the flanges rating difference between PN64 and PN63? As we known, for the flange norms of DIN, BS4504 and UNI, flanges rating is PN64 for the nominal pressure, but from EN1092-1 norm, the nominal pressure revised to PN63. EN1092-1 norm was published later than DIN, UNI and BS4504, so I think maybe in future, PN63 will be popular nominal pressure to instead of PN64, this is the difference, but nowadays, we both use PN63 and PN64 rating for flanges, and PN63 flange, PN64 flange, maybe have not so much difference, this is my discovery, for any mistakes, can leave comments to m, thanks a lot.

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.

Flange Facing Types

Flange Facing Types

One end of the flex joint is a flat face to match the pump face and the other end is raised face to match the flange.
  • Flat Face (FF) – Typically these flanges are used on pump facings or on fiberglass flanges where the torque of compressing the gasket will damage the flange body. They are found in 150# and 300# ratings. Their principal use is to make connections with 125# and 250# cast iron flanges, respectively.
  • Raised Face (RF) – The raised face is the most common used flange face. It is called raised face because the gasket is raised 1/16″ and 1/4″ above the bolt circle face: 1/16″ for 300 lb. and less, 1/4″ for 400 lb. and more. The flange facings are machine finished toANSI/ASME B16.5 requirements.
  • Ring Type Joint (RTJ) (Class 300 and larger) – This flange is normally used for high pressure gas pipe work. Ring type gaskets must be used on this type of flange.
  • Tongue and Groove (T&G)
    • Small Tongue and Groove
    • Large Tongue and Groove
    • Small Male and Female
    • Large Male and Female

Flange Facing Finish

The flange face finish is determined by the standard used and measured as an Arithmetical Average Roughness Height (AARH). An example would be ANSI B16.5 which specifies face finishes within a range 125AARH – 500AARH (3.2 Ra to 12.5 Ra).

  • Cold Water – It has a mirror like finish. This is made with a wide tool at a high speed which gives a finished surface much like a ground surface. When a surface has this type of finish it is normally used metal to metal, not with a gasket. It is seldom used in the oil, chemical or related industries.
  • Concentric Serrated – A 90 degree inclined angle tool is used to make the grove. It makes a grove 1/64″ deep and 1/32″ apart in a concentric circle.
  • Smooth – This can be made with several different types of tool shapes. No tool markings will appear to the naked eye on the surface. The roughness of the finish is from 125-250 microinch.
  • Spiral Serrated – This is similar to a stock finish but the difference between them is the way the grove is made. A 90 degree inclined angle tool is used to make the grove. It makes a grove 1/64″ deep and the feed is 1/32″.
  • Stock – The surface is created by a continuous spiral groove. The roughness of the finish is from 125 to 500 microinches and is cut with a tool with an approximately 0.06 inches or larger radius.
