Product Introduction
Produced by Hongchang Machinery, the Twin-Wall Wear-Resistant Concrete Pump Elbow is an upgraded accessory specifically designed for high-volume concrete transportation. Featuring a double-layer composite structure, an integral inner-wall quenching process, and a thickened back arc reinforcement, it solves common pain points such as rapid wear, cracking, and slurry leakage. It is the ideal choice for high-rise buildings, bridges, tunnels, and mass concrete construction.
Core Advantages
-
Twin-Wall Wear-Resistant Structure (Double Lifespan)
The high-strength cast steel outer layer ensures impact resistance, while the high-hardness inner wear layer reaches a hardness of HRC58-62. A single elbow can withstand a concrete conveying volume of over 60,000 cubic meters, lasting more than 3 times longer than ordinary elbows.
-
Reinforced Thickened Back Arc
Addressing the area most prone to rapid wear, the back arc features a thickened design to significantly improve durability in critical zones and prevent premature scrapping due to localized wear.
-
Standard Dimensions & Universal Compatibility
Manufactured strictly according to national and industry standards. The diameter, angle, and bending radius are precisely matched to fit global mainstream brands such as Sany, Zoomlion, XCMG, Xingma, Putzmeister, and more.
-
Stable Welding Performance (No Leakage or Bursting)
The integral heat treatment process eliminates internal stress. Precision-machined welding grooves ensure no cracking or deformation during field welding, eliminating risks of slurry leakage or pipe bursting to guarantee construction safety.
-
Full Specification Customization
Supports customization for various angles (90°/45°/30°/15°), bending radii (R180/R190.5/R275), and full-bore diameters (DN100/DN125/DN150) to meet diverse construction requirements.
Scope of Application
-
Vertical concrete transportation for high-rise and super high-rise buildings.
-
High-volume concrete construction for bridges, tunnels, subways, and other large-scale projects.
-
Long-distance horizontal pipeline transportation for commercial concrete and mixing stations.
-
Supporting equipment for pump trucks, trailer pumps, and truck-mounted pumps.
