Product Introduction
The cast steel concrete pump elbow produced by our company is manufactured using specialized wear-resistant cast steel with an integral precision casting process. Following heat treatment and internal wall quenching reinforcement, the product offers superior wear resistance, high impact strength, and excellent crack resistance. It serves as a critical component in concrete conveying systems.
Product Advantages
Integral Cast Steel Forming: Delivers high structural strength and superior toughness.
Internal Wall Quenching: Reaches a hardness of HRC55-62, significantly enhancing wear resistance.
Extended Service Life: Lasts 2–3 times longer than ordinary elbows.
Standardized Dimensions: Fully compatible with various mainstream pump truck brands.
Excellent Welding Performance: Ensures convenient installation and zero slurry leakage.
Customizable Angles: Available in 90°, 45°, 30°, and 15° configurations.
Scope of Application
The product is suitable for various types of concrete pump trucks, trailer pumps, and truck-mounted pumps. It is widely utilized in concrete conveying scenarios such as building construction, bridges, tunnels, high-speed rail, and municipal engineering projects.
