Carbon steel flange is tight and reliable, good sealing

Carbon steel flanges are tight and reliable. It has two sealing faces, and the sealing surface material of the ball valve is widely used in various plastics, and has good sealing performance and can achieve complete sealing. Since the carbon steel flange has wiping properties during the opening and closing process, it can be used in a medium with suspended solid particles. Model Q41F--16C Q41F--25C American standard A105 is about 0.9% (standard is 1.05Max with decreasing carbon content can reach 1.65% Max). The national standard 16Mn content is about 1.3% (standard 1.2%~1.6%) Japanese standard S25C If it is lower than 0.6%.

The production process includes forging, casting, medium plate rolling, and medium plate cutting. Among them, the forging price is the highest, the middle plate product is the second, and the casting product is the lowest. In terms of quality, the best for forging, the second for rolling, and the third for casting. However, the forgings are generally small in diameter.
