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.

The pressure marking specified in this standard is divided into PN marking and Class marking.
PN marking has 12 pressure ratings
They are: PN2.5; PN6; PN10; PN16; PN25; PN40; PN63; PN100; PN160; PN250; PN320; PN400
Class is marked with 6 pressure ratings
They are: Class 150; Class 300; Class 600; Class 900; Class 1500; Class 2500
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 steel processing flange, usually this steel is chemical composition and mechanical properties of the substandard scrap, and even the use of black steel mill private steelmaking to produce flanges, The steelmaking technology used in this private steelmaking is outdated and cannot guarantee mechanical properties and welding properties, and it may not be possible to weld with steel pipes when used, or the steel itself will leak after welding. Therefore, when buying flanges, try to use carbon steel flanges.
