Model Number: RING
Brand Name: ZZHJ
Key Specifications/Special Features:
Precision-machined carbide ringHigh strength, tough, wear and corrosion resistance, excellent heat-conducting property and hard alloy sealing rings provided by Zhuzhou Huijin Carbide are mainly applied in some places with terrible environment.Zhuzhou Huijin Carbide designs different marks according to different environment, products can be divided into inlaid hard alloy stationary ring and solid carbide stationary ring according to the structure, such as different types with/without anti-rotating pins(Refer to product catalog for details)Ordinary marks of hard alloy sealing rings produced by the company as follows:Mechanical seal ring are used to seal the clearance between the rotating shaft and the stationary housing in equipment such as pumps and mixers, so that liquid cannot leak out through this clearance
Tungsten carbide is the most excellent seal face material in the seal material world
One of main reasons for using Tungsten Carbide is the additional wear resistance that can be achieved in both moving and static parts
This is particular the case in serve service conditions, such as high temperature, and high levels of corrosion and abrasion
Widely used in oil refineries, petrochemical industries, fertilizer plants, petrochemical plants, pharmaceutical industries
Product information: 1. Characteristics of abrasive resistance, corrosion resistance and stable property performance, protective bushings, anti-friction, silence block, separate harmful from bearing, sleeve protector
2. High precision, variously available size and shape
3. H6 tolerance, fine Polishing, mirror surface
4. Non-magnetic
Quality controlDuring production process, we adopt the advanced production system and modern technology to monitor all-round quality control from theraw material to final product
