Other Descriptions

Carbon steel pipe flange introduction:
Carbon steel flange, that is, the body is made of carbon steel flange plate or end flange connectors. Flanges containing carbon steel are called carbon steel flanges. Commonly used materials are cast carbon steel grade WCB, forging A105 or Q235B, A3, 10#, 20# steel, 16 manganese, 45 steel, Q345B and so on.
Usually, in order to prevent rust, the surface of the flange is plated (yellow zinc, white zinc, etc.), or brushed with anti-rust oil and sprayed with anti-rust paint.

Carbon steel flange technical conditions:
The pressure marking specified in this standard is divided into PN marking and grade marking.
PN mark has 12 pressure levels: PN2.5; PN6; PN10; PN16; PN25; PN40; PN63; PN100; PN160; PN250; PN320; PN400.
There are 6 pressure levels labeled: Class 150; Class 300; Class 600; Class 900; Class 1500; Class 2500.
Features and parameters:
Carbon steel flange sealing is reliable. It has two sealing surfaces, the sealing surface material of the ball valve is widely used in a variety of plastics, good sealing performance, can realize complete sealing. Since carbon steel flange has wiping performance during opening and closing, it can be used for media containing suspended solid particles. Model Q41F-16C Q41F-25C American Standard A105 is about 0.9% (standard is 1.05Max, carbon content down to 1.65% Max), National Standard 16Mn is about 1.3% (standard is 1.2% to 1.6%), and Japanese Standard S25C is less than 0.6%.
