Carbide sealing ring characteristics

1. Carbide sealing ring has the characteristics of wear resistance and corrosion resistance, and is widely used in mechanical seals in petroleum, chemical and other fields. 300mm;

2. The product is finely ground, the size and tolerance are extremely small, and the sealing performance is excellent;

3. Corrosion-resistant rare elements are added to the process formula, and the sealing performance is more durable;

4. It is made of high-strength and high-hardness carbide material, which is not deformed and more compressive.

Technical requirements for sealing rings:

1. The grade of cemented carbide used in the blank and its physical, mechanical properties and gold correspond to the requirements of the relevant standards:

2. The depth of the edge drop and corner drop of the blank is not more than 0.33mm;

3. The surface of the blank shall not have defects such as peeling, bubbling, delamination, cracks, pores, over-burning and under-burning;

4. The cross-sectional structure of the blank should be uniform, and there should be no defects such as black hearts, air bubbles, delamination, cracks, severe carburization, decarburization and uncompression. Inspection rules and methods

The inspection rules of the blank are implemented in accordance with the provisions of GB5242.
