Nanjing Litai High-Pressure Water Descaling System Sets a New Benchmark for Longevity in Forging Industry

               In industrial manufacturing, descaling machines are often regarded as a "consumable killer" and a major maintenance headache on production lines. However, recently, reporters learned from Liju, a large Chinese forging enterprise, that a descaling production line has been operating continuously under heavy load for five years. Its core equipment — the high-pressure water descaling system independently developed by Nanjing Litai — has not required any major overhaul to date, and its descaling performance remains as excellent as when it was first commissioned. The oxide scale removal rate is stably above 98%, setting a benchmark for long-term stable operation in the industry.

             Five Years of Refinement: On-site Witness of Durable Performance

Inside the customer’s forging workshop, red-hot steel billets glow intensely. With an instant burst of high-pressure water, surface oxide scale falls off immediately, revealing a clean metallic surface. Since its technical renovation and commissioning in 2019, this production line has been in service for more than 1,825 consecutive days.

           “To be honest, when we purchased this system, we were mentally prepared to replace a batch of core components every two years,” said Director Li, the equipment manager at the forging plant.

           “After five years, this descaling machine has pleasantly surprised us. It has not suffered any structural fatigue damage, nozzle wear is minimal, and pump pressure output remains stable. Every time we inspect the equipment, seeing the wear-resistant lining and sealing structure, we know we made the right choice.”

          Core Strengths: Superior Quality Proven by Cleaning Performance

          Why can this descaling machine stand the test of time? According to our Technical Director, it benefits from three core technologies:

         Ultra-wear-resistant materials:

         For the high hardness and erosiveness of forging oxide scale, wetted parts use high-chromium wear-resistant alloy and special ceramic coating composite technology, reducing the wear rate to 1/3 of the industry average.

         Precise fluid dynamics design:

        Jet angle and impact force optimized via CFD simulation ensure that even with slight nozzle wear after five years, the descaling effect remains sharp and thorough, with extremely low surface residue, greatly reducing subsequent roll wear.

       Long-life sealing system breakthrough:

       Seals are a common weak point in high-pressure water systems. This equipment adopts floating combined sealing technology, effectively solving seal leakage caused by water hammer and high temperatures, achieving zero replacement of the main sealing system in five years.

       Customer Testimonial: Not Just Cost Savings, But Efficiency Improvement

“The economic benefits of this long-term performance are obvious,” said Operator Wang.

“With previous equipment, descaling quality declined after one to two years, causing surface pits and higher scrap rates. After five years, this machine still cleans billets as clean as new, cutting our grinding workload by more than half.”

        In five years of operation, the descaling machine has processed over 500,000 tons of steel billets, directly saving customers more than 1 million yuan in spare parts costs, with nearly zero production downtime due to equipment failure.

        Five years is the best yardstick to verify the design rationality, material durability, and manufacturing precision of heavy-duty equipment.

        With this real case, our company proves that truly reliable equipment excels not only at startup but also over years of service.

         In the future, we will continue to focus on ultra-long service life and stable performance, helping more forging enterprises achieve green, efficient, and low-consumption production transformation.
