WCB Carbon Steel Flanges

Carbon metal flange, that is, the flange or stop flange connector made of carbon steel. It consists of a flange made of carbon steel, which is known as a carbon metal flange. Common substances are forged carbon metal grade WCB, forging A105, or Q235B, A3, 10#, #20钢, sixteen manganese, 45 steel, Q345B, etc.

Usually to forestall rust, there is an electroplating layer (yellow zinc, white zinc, etc.) on the floor of the flange, or brush anti-rust oil and spray anti-rust paint.

The strain marks distinctive in this wellknown are divided into PN marks and Class marks.

The PN is marked with 12 stress classes

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

Class is marked with 6 stress classes

They are: Class 150; Class 300; Class 600; Class 900; Class 1500; Class 2500

Another which means of carbon metal flange is: the flange produced in accordance with the dimension and tolerance vary required via the countrywide standard, which is exclusive from the flange that is now not produced in accordance to the fashionable size, additionally recognised as the 2d preferred flange (some human beings name the non-standard flange is incorrect), commonly some unscrupulous retailers will decrease the thickness of the flange, The outer diameter of two sizes to acquire the cause of saving materials, as nicely as the use of scrap metal or scrap metal processing flange, generally this metal is a chemical composition and mechanical homes of the substandard waste, even greater with the black metal mill non-public steelmaking manufacturing flange, the non-public steelmaking science used in this non-public steelmaking can no longer assurance the mechanical homes and welding performance, the use of metal might also now not be in a position to weld with the metal pipe, or the metal itself has cracks, pores, etc. Therefore, when shopping for flanges, attempt to pick out carbon metal flanges.

Features and parameters

Carbon metal flanges are tight and reliable. It has two sealing surfaces, and the sealing floor cloth of the ball valve is extensively used in a variety of plastics, which has accurate sealing overall performance and can acquire whole sealing. Since carbon metal flanges are wipeable in the course of opening and closing, they can be used in media with suspended stable particles. Model: Q41F--16C Q41F--25C American wellknown A105 is about 0.9% (the fashionable is 1.05Max, which can reduce with the carbon content material to 1.65% Max), and the content material of the countrywide general 16Mn is about 1.3% (standard 1.2%~1.6%), and the Japanese popular S25C is rather low, beneath 0.6%.

Commonly used processes

The manufacturing method consists of forging, casting, medium plate rolling, medium plate cutting, etc.

Among them, the forging fee is the highest, the medium plate product is the second, and the casting product is the lowest. In phrases of quality, cast is the best, rolled is the second, and forged is the third. But the diameter of the forging is typically smaller.
