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.

Are there any relations between AWWA C207 CLASS D, E, F Flanges and BS 10 Table D, E, F Flanges?

As you known, AWWA C207 is American Water Works Association standard for flanges, they have Class D, E, F etc, different is flange’s thickness using for different pressure. But in BS 10 standard, also have Table D, E, F Classes for flanges, so I guess, maybe they have some relations about the 2 norms of flanges. Who can answer me to this question? Maybe I am wrong, they have no relations, just have the same name? Waiting for your comments.

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.

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).

Chinese New Year – Spring Festival

Chinese New Year is the most important of the traditional Chinese holidays. In China, it is known as “Spring Festival,” the literal translation of the Chinese name 春節 (Pinyin: Chūn Jié), owing to the difference between Western and traditional Chinese methods for computing the seasons. It marks the end of the winter season, analogous to the Western carnival. The festival begins on the first day of the first month (Chinese: 正月;pinyin: Zhēng Yuè) in the traditional Chinese calendar and ends with Lantern Festival which is on the 15th day. Chinese New Year’s Eve, a day where Chinese families gather for their annual reunion dinner, is known as Chú Xī (除夕) or “Eve of the Passing Year.” Because the Chinese calendar is lunisolar, the Chinese New Year is often referred to as the “Lunar New Year“.

Chinese New Year is the longest and most important festivity in the Chinese calendar. The origin of Chinese New Year is itself centuries old and gains significance because of several myths and traditions. Chinese New Year is celebrated in countries and territories with significant Chinese populations, such as Mainland China, Hong Kong,[2] Indonesia, Macau, Malaysia, Philippines, Singapore,[3] Taiwan, Thailand, and also inChinatowns elsewhere. Chinese New Year is considered a major holiday for the Chinese and has had influence on the lunar new year celebrations of its geographic neighbors, as well as cultures with whom the Chinese have had extensive interaction. These include Koreans (Seollal), andBhutanese (Losar), Mongols (Tsagaan Sar), Vietnamese (Tết), and the Japanese before 1873 (Oshogatsu).

In countries such as Australia, Canada and the United States, although Chinese New Year is not an official holiday, many ethnic Chinese hold large celebrations and Australia Post, Canada Post, and the US Postal Service issue New Year’s themed stamps.

Within China, regional customs and traditions concerning the celebration of the Chinese new year vary widely. People will pour out their money to buy presents, decoration, material, food, and clothing. It is also the tradition that every family thoroughly cleans the house to sweep away any ill-fortune in hopes to make way for good incoming luck. Windows and doors will be decorated with red colour paper-cuts and couplets with popular themes of “good fortune” or “happiness”, “wealth”, and “longevity”. On the Eve of Chinese New Year, supper is a feast with families. Food will include such items as pigs, ducks, chicken and sweet delicacies. The family will end the night with firecrackers. Early the next morning, children will greet their parents by wishing them a healthy and happy new year, and receive money in red paper envelopes. The Chinese New Year tradition is to reconcile, forget all grudges and sincerely wish peace and happiness for everyone.

Although the Chinese calendar traditionally does not use continuously numbered years, outside China its years are often numbered from the reign of the Yellow Emperor. But at least three different years numbered 1 are now used by various scholars, making the year beginning in 2012 AD the “Chinese Year”

Based on a weighted average of prices, the People’s Bank of China, or central bank, sets the central parity rate of the renminbi against the U.S. dollar before the opening of the market each business day.s

“The central parity price is the intention of the central bank. And a higher price shows the central bank’s determination to maintain the appreciation of the Chinese currency. The market has fully received the signal,” a trader told the National Business Daily.

“In view of market trade, profit taking and settlement has pushed up the renminbi. Banks are selling U.S. dollar positions and enterprises are increasing settlements due to accounting needs,” the trader said.

UBS Securities expects the renminbi to stabilize at around 6.35 against the green back at the end of this year and rise by 3% to 6.15 at of the end of 2012.

JP Morgan Chase reckoned China’s real GDP growth would rise 8.2% at an annualized rate in 2012 and the current account surplus would account for 2.8% of GDP next year. The Chinese currency would continue to appreciate by about 4% against the U.S. dollar in 2012.
