China Pipe Flange Exporter, Distributor, Supplier Carbon Steel Pipe Flange Size 1/2″ (15 NB) to 48″ (1200NB) Standards ANSI ASME BS DIN EN JIS Easy To Disassemble And Separate Pipes For Repair And Regular Maintenance, Usually To Prevent Rusty Flange Surface With Electroplating Layer (yellow zinc, white zinc, etc.), or Brush Anti-Rust Oil And Spray Anti-Rust Paint Treatment
Carbon steel flange, that is, the flange plate or the end flange connection piece whose body is made of carbon steel. The flanges containing carbon steel are called carbon steel flanges. Common materials are cast carbon steel grades WCB, forgings A105, or Q235B, A3, 10#, #20 steel, 16 manganese, 45 steel, Q345B, etc.
Usually in order to prevent rusty flange surface with electroplating layer (yellow zinc, white zinc, etc.), or brush anti-rust oil and spray anti-rust paint treatment.
The pressure mark specified in this standard is divided into PN mark and Class mark.
The carbon steel flange is tight and reliable. It has two sealing surfaces, and the sealing surface materials of the ball valve are widely used in various plastics, which have good sealing performance and can achieve complete sealing. Because the carbon steel flange has wiping properties during the opening and closing process, it can be used in media with suspended solid particles. Model Q41F--16C Q41F--25C American standard A105 is about 0.9% (the standard is 1.05Max and the carbon content decreases to 1.65%Max) As for the national standard 16Mn content is about 1.3% (standard 1.2% to 1.6%), the Japanese standard S25C Then it is lower than 0.6%.
