Flanges Introduction:A flange is a approach of connecting pipes, valves, pumps and other gear to form a pipework system. It additionally provides handy access for cleaning, inspection or modification. Flanges are typically welded or crewed into such systems and then joined with bolts.Product Specification:1. Standard:BS4504 2. Type:Plate flange, Threaded, Irrigation,Blind, Lap Joint flange. Type3. Pressure Class:PN6;PN10; PN16; PN25; PN40; 4. Dimension:DN10-20005.

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.

Another layer of carbon steel flange means: according to the size and tolerance range required by the national standard production of flanges, different from the flange pieces not produced according to the standard size is also called two standard flanges (some people call non-standard flanges are incorrect), usually some unscrupulous merchants will reduce the thickness of the flange, the outer diameter of the two dimensions to achieve the purpose of saving materials, and the use of scrap steel or scrap steel1.

     Carbon steel flange, that is, a flange plate or end flange connection made of carbon steel. It contains a flange made of carbon steel, called a carbon steel flange. Common materials are cast carbon steel grade WCB, forgings A105, or Q235B, A3, 10#, #20steel, 16 manganese, 45 steel, Q345B, etc.Usually to prevent rust flange surface has an electroplating layer (yellow zinc, white zinc, etc.), or brush antirust oil and spray antirust paint.Chinese national standard for carbon steel flange GB/T9119-2010 marine standard CB M1001-81 thermal power standard D-GD87-1101 1.
