Carbon Steel Flange

Carbon steel flange, that is, the body material is carbon steel flange plate or end flange connector.

  • Details

Carbon steel flange, that is, the body material is carbon steel flange plate or end flange connector. The flange containing carbon steel is called carbon steel flange. Common materials are cast carbon steel brand WCB, forging parts A105, or Q235B, A3, 10#, #20 steel, 16 manganese, 45 steel, Q345B, etc.

Usually to prevent rusting flange surface has electroplating layer (yellow zinc, white zinc, etc.), or brush anti-rust oil and spray anti-rust paint treatment.

Parameters and Characteristics:

Carbon steel flanges are compact and reliable. It has two sealing surface, and at present ball valve sealing surface materials are widely used in various plastics, good sealing, can achieve complete sealing. Carbon steel flanges can be used in medium with suspended solid particles because of their wiping property during opening and closing. Model Q41F--16C Q41F--25C standard A105 is about 0.9% (the standard is 1.05Max can be up to 1.65% Max as the carbon content decreases) while the national standard S25C is about 1.3% (standard 1.2% ~ 1.6%), which is lower than 0.6%.

Commonly used process

The production techniques include forging, casting, coiling and cutting.

Among them, forging price is high, medium plate product is second, casting product is low. In terms of quality, the forging is good, the rolling is second and the casting is third.But the forging diameter is generally small.
