Mine Wear-Resistant Pipeline

Xi'an Zhongxing Materials Co., Ltd. (Contact: Yu Baoyan 18509217851) was established in 1997 and is affiliated with Xi'an University of Architecture and Technology. The company's various products have obtained more than 20 national patents.

The company mainly produces and sells: bimetallic composite wear-resistant pipelines (elbows, straight pipes, special-shaped pipes), high-strength hardfacing wear-resistant pipelines, filling pipelines, wear-resistant liners, hardfacing wear-resistant grinding discs, and hardfacing wear-resistant grinding rollers.

It has a 202-acre production base in Tongchuan, Shaanxi, and its various products are sold to power plants and major mines nationwide (such as Gansu Jinchuan Group Co., Ltd., Tongling Nonferrous Metals Holding Group Co., Ltd.; Anhui Zhonggang Group Co., Ltd.; various branches of China Aluminum Group).

Features of the wear-resistant pipelines produced (using the lost foam vacuum suction casting process): 1. Excellent comprehensive performance (resolving the conflict between weldability and wear resistance that is difficult to balance with single materials, maximizing material performance advantages, ensuring safe and reliable use, with a service life in power system pulverized coal pipelines generally exceeding 80,000 hours)2. High wear resistance (macro hardness of the wear-resistant layer above HRC50)3. Strong corrosion resistance, high-temperature resistance 4. Advanced and stable composite process (these wear-resistant pipes are manufactured using the lost foam vacuum suction casting composite process, avoiding issues like sand washing and sand inclusion common in traditional sand casting; due to casting under a vacuum system, defects such as pores are also eliminated.)5. Low pipeline system resistance, aesthetically pleasing appearance (elbows and other special-shaped pipes can be fully composite. This changes the traditional method of making elbows and other special-shaped pipes with folded lines, does not alter the material’s movement trajectory in the elbow, results in lower resistance, and reduces energy consumption)6. Good thermal shock resistance 7. Easy transportation, installation, and use (lost foam vacuum suction cast composite wear-resistant pipes can be installed using flanges, quick couplings, or direct welding).

High-strength hardfacing wear-resistant pipes use steel pipes as the base material, with a specialized CNC welding machine applying a professional hardfacing process to automatically weld a wear-resistant layer on the inner wall (working surface). Their characteristics: 1. True metallurgical bonding—since the wear-resistant welding wire is evenly welded onto the base steel pipe, it effectively forms a metallurgical bond, preventing separation or peeling of the inner liner and outer pipe; 2. High wear resistance and long service life—Cr7C3 hard compound volume fraction above 50%, providing superior wear resistance; 3. Good impact resistance; 4. Low pipeline operating resistance; 5. Large single supply length, formed without welding; 6. Excellent thermal shock resistance; 7. Thin inner wall, lightweight, facilitating installation, transportation, and maintenance.

Our company has developed and produced bimetallic wear-resistant pipelines that resolve the conflict between toughness, weldability, thermal shock resistance, and wear resistance. We have invented several new processes for the integrated large-scale preparation of pipeline composite products, solved the challenge of fully compositing special-shaped pipelines, addressed the metallurgical bonding issues in metal-metal composites, and tackled the lifespan design of pipe and cylinder flow components. These pipelines offer product advantages unmatched by other wear-resistant pipelines.
