Tungsten carbide sleeve uses:
Carbide sleeves are widely used in many fields, mainly including petrochemical, submersible oil pumps, slurry pumps, water pumps, centrifugal pumps and other industrial equipment. In these applications, carbide sleeves are mainly used to reduce wear, seal and protect components, and have the characteristics of high hardness resistance, high corrosion resistance, pressure resistance, wear resistance and high bending strength.
In addition, carbide sleeves also play an important role in the following specific application fields:
Valve application: In valves, carbide sleeves are installed in the stem cover steam trap to reduce valve leakage and seal.
Bearing application: In bearings, carbide sleeves are used to reduce wear between bearings and shaft seats and avoid increasing the gap between shafts and holes.
Petroleum industry: In the process of oil exploration, carbide wear-resistant sleeves are widely used in various mechanical equipment, carbide wear-resistant sleeves are used to oil extraction pump components to ensure stable operation of equipment in rugged drilling environments, greatly improving drilling efficiency.
