Due to their exceptional hardness, wear resistance, and corrosion resistance, carbide wear parts have become key materials in the oil drilling industry.
In high-pressure and high-temperature environments, these wear parts can effectively reduce wear and corrosion, enhancing the reliability and service life of equipment. For example, bases and sleeves endure immense mechanical stress during drilling operations. The use of carbide materials ensures that these components do not deform or wear out, thus ensuring the continuity and safety of drilling operations.
Xionghen Technology will continue to commit to providing customers with high-quality, custom wear parts to meet the demands of different working conditions, supporting the sustainable development of the oil drilling industry.
Abrasive particles, high temperatures, corrosive chemicals, and high loads can all contribute to a failure in rotating equipment.
PDC bearings improve overall bearing reliability in harsh conditions while eliminating the need for seals.
PDC is not a diamond coating, but instead it is a thick, manmade diamond surface that is ideally suited for operation in process fluids
where abrasive particles, like sand, can cause accelerated wear and failure with traditional bearing materials.
The Advantages of PDC:
High thermal conductivity: The PDC material reduces the local limit temperatures that lead to bearing degradation and prevents damage to the bearing material caused by the high heat .
High load: They can operate effectively over a wide range of speeds and loads. For example, in some oil and gas drilling, diamond bearings can operate at loads of up to 60,000 pounds at 100-6,000 rpm.
Wear-resistance and high temperature resistance: The PDC material has an extremely low coefficient of friction (coefficient of friction between 0.01 and 0.03). It can operate at high temperatures (up to 233℃).
High fracture toughness: Bearing materials with excellent fracture toughness reduce the likelihood of damage caused by shock loads.
High corrosion resistance: They can be unaffected by corrosive substances in the application environment.
Simplicity: There is no need for specialized lubrication during use, simplifying equipment and components by eliminating the need for seals and separate lubrication systems.
Long life: The service life is more than 6 times longer than that of tungsten carbide bearings.
Because of its extreme hardness, PDC is ideally suited to resist wear from abrasive particles inlubricants and process fluids.
