Product Introduction

The concrete pump pipe cast clamp produced by Hongchang Machinery is a core accessory for pipeline connection and sealing fixation within concrete conveying systems. Utilizing high-strength ductile iron or cast steel with an integral casting process, the product offers high structural strength and impact resistance. When paired with dedicated rubber sealing gaskets, it effectively prevents leaks and supports rapid assembly, serving as a universal accessory for pump trucks, trailer pumps, and truck-mounted pump pipeline systems.

Core Advantages

1. Integral Casting for Maximum Strength Constructed from high-quality ductile iron or cast steel through integral casting, ensuring uniform wall thickness and excellent toughness. It withstands high-pressure impacts during concrete transport without deformation or fracture, adapting to complex job site conditions.

2. High-Pressure Leak Prevention & Reliable Sealing The internal sealing groove, combined with dedicated high-pressure rubber gaskets, ensures a tight fit that eliminates slurry leakage during high-pressure pumping, guaranteeing construction safety and continuity.

3. Rapid Assembly & High Construction Efficiency The snap-on quick-install design requires no complex tools, allowing a single person to complete installation and disassembly. This significantly shortens pipeline setup and maintenance time, enhancing overall efficiency.

4. Full Specification Compatibility & High Interchangeability Manufactured strictly to industry standards with precise dimensions, it fits DN100, DN125, and DN150 full-range concrete pump pipes. It is compatible with pipeline systems of major brands including Sany, Zoomlion, XCMG, and Putzmeister.

5. Wear-Resistant & Rust-Proof for Long Service Life The surface undergoes shot blasting and rust-proof spraying to resist corrosion and oxidation. It remains rust-free in humid environments and maintains stable engagement performance over long-term use.

Scope of Application

• Pipeline connections for various concrete pump trucks, trailer pumps, and truck-mounted pumps.

• Concrete conveying pipeline systems for high-rise buildings, bridges, tunnels, and municipal projects.

• Interface fixation and sealing for long-distance horizontal conveying pipelines in commercial concrete stations.

• Rapid connection scenarios for various high-pressure fluid conveying pipelines.
