Ceramic wear-resistant elbows have gained market favor and continuously replaced some traditional wear-resistant materials. The fundamental reason lies in their excellent product quality and their multifaceted advantages over traditional wear-resistant materials, such as cast stone, cast steel, and bonded ceramic materials.

Performance Comparison

Cast Stone

In the past, most factories used cast stone elbows, which are characterized by their fragility, tendency to crack, and wear-resistant surfaces. The wall thickness ranges from 25-35mm, with some reaching nearly 40mm. After short-term wear and cracking on the inside, coal dust wears through the gaps to the outside, rendering their lifespan just one major repair cycle. Moreover, they often have internal air holes, which can lead to hidden dangers. Once worn through, there's no way to repair them on-site.

2. Cast Steel

Ductile iron, including alloyed steel, is widely used in the abrasion resistance field due to its relatively simple manufacturing process. However, due to the inherent limitations of the material's properties and process restrictions, the surface hardness of cast iron (approximately 60) is significantly lower than that of ceramics (above 80), and its wear resistance is only a fraction to a few tenths of ceramics (specific data can be found in the Wear Test Reports of Central South University's Powder Metallurgy Institute and the results of the Jet Abrasion Test from the Kyushu Institute of Industrial Ceramics in Japan). Elbows manufactured from this material can wear through after over a year of operation. Additionally, cast iron pipes are thick and very heavy, with a high carbon content, resulting in poor weldability. On-site heat treatment of the welds is required, which presents considerable difficulties for installation and maintenance.

3. Glue ceramic tiles

Micro gaps are abundant, the material is brittle and prone to breakage, easily causing localized failure, and it's difficult to repair after detachment.
