Anneaux d'étanchéité en carbure

Carbide sealing rings and carbide rings are primarily used as mechanical seals and accessories for cement pump trucks. These rings must not only possess high hardness and strength, but also excellent corrosion resistance and rust resistance. Tungsten carbide sealing rings installed in water pumps must also be machined with high precision. Failure to meet these requirements will result in a poor fit and potentially leaks.
