Wear-resistant special-shaped pipe part

Wear-resistant special-shaped pipe parts are composite wear-resistant components formed by "tailoring" to the actual spatial shape of the equipment (elbows, tees, branches, spirals, variable diameters, conical hoppers, chutes, etc.) and arranging high-hardness ceramic tiles with a thickness of 4-50 mm, which are then adhered and fixed. Product Performance High hardness and wear resistance: Hardness is second only to diamond, about 5 times that of ordinary steel, and can effectively resist high-concentration particle erosion and sand and gravel impact, significantly extending equipment service life. Excellent high-temperature resistance: Maintains stable performance in high-temperature environments, some can operate normally at temperatures up to 1000℃, suitable for metallurgy, heat treatment, and other high-temperature work scenarios. High corrosion resistance: Ceramic materials have good resistance to chemical media such as acids and alkalis, and can effectively prevent equipment from being corroded and damaged in environments with corrosive substances such as in chemical and mining industries. Lightweight and high-strength: After special processing, weight is effectively controlled while maintaining good strength, making installation and use convenient, and can also reduce equipment load. Installed firmly: Usually installed by combining strong adhesive bonding with mechanical fastening, such as using specially designed high-temperature resistant ceramic adhesive paired with grooves, bolts, etc., to ensure the ceramic patch is tightly bonded to the equipment surface and is not easily detached.

In mining development, which type of wear-resistant pipe offers a better balance between functional adaptability and economy for long-distance transportation of media such as mineral concentrate and slurry?

SHS ceramic lined composite steel pipe exhibit high hardness and excellent wear resistance. The smooth surface of the ceramic lining, with its low roughness, reduces frictional resistance during media transport, effectively resisting wear caused by particle erosion and reducing energy consumption. In long-distance transport, it can reduce the load on pumps and save operating costs, making it a superior choice for long-distance media transport.

The oil industry deals with high-pressure transportation of sand-containing crude oil, and the sand particles are abrasive. From the perspective of compression resistance and wear resistance, which material would be more suitable?

High-pressure crude oil transportation containing sand requires a balance between pressure resistance and wear resistance. SHS ceramic lined composite steel pipe offer good wear resistance but are brittle and prone to cracking under high pressure, with only moderate pressure resistance. Hard ceramic patch composite steel pipe have good wear resistance, but the bonding strength of the laminations may be affected under high pressure, posing a risk of detachment. Bimetallic composite steel pipe have a strong base steel pipe with high pressure resistance, and the wear-resistant alloy layer addresses sand abrasion. Their overall performance is well-suited to high-pressure conditions; although more expensive, they guarantee stability under high-pressure conditions. Therefore, Bimetallic composite steel pipe remain the more suitable choice.

In the chemical industry, when transporting corrosive acid and alkaline solutions, which material is more suitable—considering both corrosion resistance and wear resistance reliability?

The core advantage of SHS ceramic lined composite steel pipe lies in the chemical stability of the ceramic lining, exhibiting extremely strong corrosion resistance to acid and alkali solutions and effectively resisting the erosion of hydrogen ions and hydroxyl ions. Simultaneously, the high hardness of ceramic provides good resistance to wear from small amounts of solid particles in solutions. In scenarios with few solid particles and moderate impact, SHS ceramic lined composite steel pipe offer the best cost-performance ratio.

Adaptability to metallurgical high-temperature dust scenarios (temperature >300°C)?

Ceramic patch tube + external insulation layer.

Alumina ceramics can withstand temperatures up to 800℃, but the steel pipe body needs to be protected against high-temperature deformation;

SHS ceramic lined are prone to cracking at high temperatures due to differences in their coefficients of thermal expansion.

In bimetallic tubes, the hardness of high-chromium cast iron decreases by 50% at temperatures above 400℃, and its wear resistance drops sharply.
