Qingyun Hongsheng Machinery Parts Co., Ltd. is one of the most reliable manufacturers and suppliers of inner lining ceramic patch composite elbow in China. We warmly welcome you to wholesale high quality inner lining ceramic patch composite elbow at low price from our factory. If you have any enquiry about quotation, please feel free to email us.
Ceramic patch elbows achieve enhanced performance and longevity in harsh pipeline environments by bonding high-strength ceramic patches to the inner walls of metal elbows, forming a composite structure. These composite elbow fittings offer nominal diameters ranging from DN50 to DN2000 or larger, with common sizes including DN50, DN65, DN80, DN100, DN125, DN150, DN175, DN200, DN225, DN250, DN300, DN350, and DN400
Products Description
Core advantages of ceramic patch elbow:
1. Exceptional Wear and Impact Resistance
Ultra-High Hardness Protection:
The ceramic layer employs corundum ceramic (α-Al₂O₃) with ≥95% alumina content, achieving a hardness of HRA ≥85 (approaching diamond level) and over 10 times the wear resistance of quenched medium-carbon steel. A 5mm ceramic layer provides equivalent protection to a 50mm-thick wear-resistant cast steel, effectively resisting abrasion from hard particles like ores and coal dust.
Composite Structure Optimization:
Ceramic tiles are tightly bonded to the metal substrate using high-temperature adhesive (with 1250°℃ heat resistance), complemented by a "three-sided interlocking" design that balances ceramic's hardness with metal's toughness, significantly reducing impact-induced detachment risks.
2. High-Temperature and Corrosion Resistance
High-temperature Stability:
The ceramic layer demonstrates a temperature resistance of ≥1760℃, while the inorganic adhesive maintains a temperature tolerance of 1250℃. This makes it suitable for extreme environments such as power plant steam pipelines and metallurgical high-temperature furnace gases.
Chemical Erosion Resistance:
The ceramic material exhibits strong resistance to corrosive media including acids, alkalis, and salts. This effectively prevents leakage risks caused by corrosion, thereby extending service life of pipelines in chemical processing and environmental protection applications.
3. Efficiency Enhancement and Cost Optimization
Reducing Fluid Resistance: The smooth ceramic inner surface (low roughness) minimizes conveying resistance and material adhesion, maintaining system flow rate and energy efficiency.
Extended Service Life and Simplified Maintenance:
With a lifespan exceeding five times that of traditional wear-resistant elbows, it significantly reduces downtime for replacements. The installation features flange markings and directional flow arrows for quick connection and maintenance.
4. Broad Applicability and Industry
Value Power Industry: Used for coal powder and ash residue conveying pipelines to solve the problem of dust leakage and wear.
Mining & Metallurgy: Suitable for conveying high-wear media such as ore powder, tailings, and coking particles.
Chemical & Environmental Protection: Ensures safe operation in conveying corrosive media (e.g., acids, alkalis, salts) and high-temperature materials.
