 YN6 Carbide +nickel mechanical seal ring

With high strength, toughness, wear and corrosion resistance and excellent heat-conducting property, hard alloy sealing rings provided are mainly applied in some places with the terrible environment. HT designs different marks according to the different environment, the 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.
 
The ordinary marks of hard alloy sealing ring produced by the company as follows:
Mechanical seal ring is 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 the 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 severe service conditions, such as high temperature, and high levels of corrosion and abrasion.
 
 It is widely used in oil refineries, petrochemical industries, fertilizer plants, petrochemical plants, Pharmaceutical industries.

Product information: 
1, The 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 control
During production process, we adopt the advanced production system and modern technology to monitor all-round
 
quality control forms the raw material to final product.
 
1. Chemical component analysis of the raw material.
 
2. Chemical analysis of the RTP powder.
 
3. Physical property testing and metallographic analysis based on trial production.
 
4. Testing the tolerance and deformation of the trial products.
 
5. Testing the physical properties of every batch of the sintered products.
 
6. Flaw detection of the molds and end products.
 
7. Testing the sizes, precision, and defects of the end products.
