Xionghen Technology offers custom services for specialized wear parts, particularly in screw drilling tools and rotary steerable system (RSS) components. RSS is commonly used in directional wells, horizontal wells, or extended-reach wells to precisely control drilling direction, improving drilling efficiency and accuracy.
With advanced technology and extensive experience, Xionghen Technology can customize specialized wear parts in various specifications and shapes according to the specific needs of customers.
The extensive use of these wear parts in screw drilling tools and rotary steerable systems not only enhances the durability and reliability of the equipment but also significantly reduces maintenance costs, supporting the efficient and safe 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.
