Qingdao Kehua Petroleum Machinery Co., Ltd. has announced a significant technological innovation in the field of mud pump parts. The company’s R&D team has successfully overcome key technical hurdles by reformulating the chemical composition of the bimetallic liner’s inner sleeve and applying an innovative “Magnetic Field Quenching” process, resulting in a quantum leap in product performance.
This “First in China” technological achievement enables Kehua’s bimetallic liners to reach an exceptional inner sleeve hardness of 65-70HRC. Compared to conventional products, this innovation extends the service life by 30%, achieving a stable operational lifespan of over 1,000 hours.
Addressing the Industry Pain Point: Why Do Mud Pump Liners Wear Out So Fast?
In oil and gas drilling operations, the mud pump is the heart of the drilling system, and the bimetallic liner is one of its most critical wear parts. Under high-pressure, high-abrasion working conditions, traditional liners often suffer from insufficient wear resistance and short lifespans. This forces drilling crews to frequently halt operations to replace mud pump parts.
This issue not only increases procurement and labor costs but, more critically, the frequent downtime directly reduces overall drilling efficiency. It has been a persistent challenge for the industry, with many customers searching for solutions on “how to improve liner wear resistance” and “long-life mud pump accessories.”
Kehua’s Innovation: Magnetic Quenching and Formula Revolution
Facing this challenge, Qingdao Kehua’s R&D team achieved a dual innovation from the perspectives of material science and heat treatment technology:
1.Optimized Inner Sleeve Composition: We conducted hundreds of experiments to refine the alloy formula of the inner sleeve. This significantly improved the base hardness and toughness of the material, laying a solid foundation for superior wear resistance.
2.Pioneering Magnetic Field Quenching: This is the core of the breakthrough. By introducing advanced magnetic field quenching technology, we can more precisely control the grain structure during the heat treatment process, making it finer and more uniform. This not only boosts the inner wall hardness to 65-70HRC but, crucially, enhances its fatigue resistance and anti-abrasion properties.
Core Value to Our Customers: Boosting Efficiency, Reducing Costs
The launch of Kehua’s new bimetallic liner brings direct and substantial economic benefits to drilling operations:
Significantly Improved Drilling Efficiency: An ultra-long service life of over 1,000 hours means less downtime for replacements, ensuring continuous and efficient drilling operations.
Drastically Reduced Operational Costs: A 30% increase in liner lifespan directly reduces the procurement frequency and inventory pressure for mud pump parts.
Reduced Maintenance Workload: More durable liners mean less frequent on-site maintenance, easing the burden on drilling crews and improving operational safety.
Setting the Industry Standard: Kehua’s Commitment
As the first enterprise in China to apply magnetic field quenching technology to bimetallic liner production, Qingdao Kehua Petroleum Machinery Co., Ltd. has once again demonstrated its technical leadership in the mud pump parts sector. We are committed to providing global customers with more reliable, efficient, and cost-effective mud pump part solutions through continuous R&D.
We believe this new technology will set a new benchmark for durability in the drilling industry.
