DESCRIPTION

Carbon steel flange, the body material is the flange of carbon steel or the end flange connecting piece. There are carbon steel flanges, called carbon steel flanges. Common materials are cast carbon steel brand WCB, forging A105, or Q235B, A3, 10 #, #20 steel, 16 mn, 45 steel, Q345B, etc.

It is usually used to prevent the surface of rust flange (yellow zinc, white zinc, etc.), or brush anti-rust oil and spray anti-rust paint treatment.

Carbon steel flange technical condition editor

The pressure marks specified in this standard are divided into PN markers and Class markers.

The PN tag has 12 pressure levels

Respectively: PN2.5; PN6; PN10; PN16. PN25; PN40; PN63; PN100; PN160; PN250; PN320; PN400

The Class tag has six levels of stress

Class 150; Class 300; Class 600; Class 900; Class 1500; The Class of 2500

Carbon steel flange of the another meaning is: according to the national standard size, the tolerance range, such as the production of flange, the difference in production is not according to the standard size of flange is also called second standard flange (someone called non-standard flange is not correct), usually some unscrupulous merchants will reduce two flange thickness, diameter size to achieve the purpose of saving material, and made from scrap steel and scrap steel flange, is usually the steel chemical composition and mechanical properties of substandard waste, moreover steelmaking production flange with black steel private, the private steel steelmaking technology using old, there is no guarantee that the mechanical properties and welding performance, use which may not be able to and steel pipe welding, such as cracks, porosity or steel itself will leak after welding. When buying the flange, try to use carbon steel flanges.

Carbon steel flange is very reliable. It has two sealing covers, and the sealing material of the ball valve is widely used in various kinds of plastic, sealing well, which can be fully sealed. The carbon steel flanges can be used in the medium of suspended solid particles due to the wipes during the opening and closing process. The model Q41F--16C Q41F--25C American standard A105 (standard is 1.05Max with carbon decrease to 1.65% Max), the 16Mn content of gb is about 1.3% (1.2 % ~ 1.6%) and the S25C is below 0.6 %.
