In industrial production, the wear and tear of equipment and pipelines is a major problem affecting the continuity and economy of production. The service life and production efficiency of industrial equipment are facing severe challenges due to the high-strength mechanical friction and dynamic impact caused by material conveying, liquid scouring and other working conditions. As the core component of industrial wear protection, the wear-resistant pipe provides a systematic solution to this problem through the innovative application of material science and engineering technology, and has been widely used in various high wear working conditions.

1.Adaptive selection of wear-resistant pipe materials

The wear mechanism in the industrial field has significant working condition specificity, and it is necessary to accurately select materials according to specific wear types and environmental conditions. In mining, coal transportation and other material conveying systems with particle erosion wear as the main failure mode, high-hardness wear-resistant materials containing chromium, nickel and other alloy elements or wear-resistant ceramic pipes lined with corundum ceramics are usually selected. These pipes can improve the abrasive wear resistance of the pipe. And in the complex working conditions of both particle erosion and chemical corrosion, with its excellent corrosion resistance and wear resistance, it has become the preferred solution to ensure the safety of pipeline use.

2.Wear-resistant pipe product system classification

( 1 ) Alloy wear-resistant pipe

By adding multi-alloy elements to the carbon steel matrix, the alloy wear-resistant pipe is treated by a special metallurgical process to form a high-performance pipe with a gradient structure. Its excellent high-temperature strength and wear resistance make it show excellent service performance in the pulverized coal conveying system of the power industry, effectively reducing the frequency of pipeline replacement and optimizing production and maintenance costs.

( 2 ) Ceramic lining wear-resistant pipe

The ceramic-lined wear-resistant pipe is composed of high hardness alumina ceramic and metal-based pipe body by hot pressing sintering or special adhesive process. The high hardness ( Mohs hardness ≥ 8 ) and chemical inertness of ceramic materials are used to realize the dual protection of particle wear and chemical corrosion in the process of material transportation in mining, metallurgy and other industries, which greatly prolongs the service life of the pipeline.

( 3 ) Rubber wear-resistant pipe

The wear-resistant pipe based on special rubber has significant application advantages in food processing, chemical fluid transportation and other fields with high requirements for flexibility and sealing due to its unique elastic modulus and cushioning performance, which can effectively reduce the impact wear of materials and ensure the safety and integrity of the transportation process.

3.The technical advantages and industrial applications of wear-resistant ceramic tubes

( 1 ) Technical characteristics

The wear-resistant ceramic tube has many outstanding properties : its Vickers hardness can reach HV1000 or more, which is significantly better than ordinary steel ; it has strong chemical stability and can maintain good structural integrity in acid-base medium. At the same time, the lightweight design improves the installation and construction efficiency by more than 30 %, which greatly reduces the comprehensive cost of the project.

( 2 ) Industry Applications

In the power industry, wear-resistant ceramic pipes are widely used in pulverized coal conveying and ash removal systems, effectively solving the problem of pipeline failure caused by high-speed particle erosion ; after the pipe is used in the ore transportation link in the mining field, the service life of the pipeline is prolonged by 2-3 times ; in the iron and steel metallurgy industry, the introduction of wear-resistant ceramic tubes in key process links such as blast furnace coal injection and sinter transportation has greatly improved the stability and operation efficiency of the production system.

As the core technical equipment of industrial wear protection, wear-resistant pipe plays an important role in improving the reliability of industrial equipment, reducing maintenance costs and promoting efficient production through material innovation and structural optimization. Reasonable selection of wear-resistant pipe materials and structural forms will provide important technical support for the sustainable development of the industrial field.
