Cemented carbide seal rings play important roles in the market of mechanical sealing industries, and they are widely used as sealing parts applying to petrochemical industries and other industries which call for superior performance in sealing.

cemented carbide seal rings As we all know that, tungsten carbide is the additional wear resistance that can be achieved in both moving and static parts, which means that cemented carbide seal rings have the characters of high wear resistance, high corrosion resistance and well compressive properties even under the service conditions of high temperature, and high levels of corrosion and abrasion.

Due to excellent performance of the material,cemented carbide seal rings are used as mechanical seal faces in pumps and compressors. According to the different binders, there are several grades of tungsten carbide material, such as YG series and YN series, etc. Generally speaking, YG series tungsten carbide provides higher hardness and better abrasion resistance, while YN series tungsten carbide enhances corrosion resistance better than the former one. According to our experience, the material of 6% nickel bonded tungsten carbide and 6% cobalt bonded tungsten carbide are the most common material for tungsten carbide seal rings.

Most cemented carbide seal rings are used to seal the clearance between the rotating shaft and the stationary housing in equipment like pumps and mixers, so that liquid can not leak out through this clearance. Besides these, cemented carbide seal rings are also used as seal faces in pumps, blowers, agitators, compressors, and other rotary shaft equipment with standard quality in oil Refineries, petrochemical industries, fertilizer plants, Petrochemical plants, Pharmaceutical industries.

cemented carbide seal zhuzhou tongda manufactures and supplies cemented carbide seal rings with various specifications, and customization is also acceptable. The followings are the merits of our cemented carbide seal rings:

1. Small concentricity.
2. Ends of the seals are flat to receive equal stress;
3. Long life-service;
4. Stable and reliable quality; 

Cemented Carbide Seals Rings have the characters of high wear resistance, high corrosion resistance and good compressive properties，It's widely used in petrochemical industries and other industries which call for high properties of the mechanical sealing rings or parts.
