Concrete delivery pipeline is a key equipment system to ensure efficient and continuous delivery of concrete in construction projects. Pump pipes directly affect the progress and efficiency of the project. ‌Classification by usage scenario‌ ‌Ground pump pipe‌: Used with fixed delivery pumps, standard length 1m/3m, flange outer diameter is divided into high pressure type (157mm) and low pressure type (148mm), need to match the system pressure level‌1. ‌Car pump pipe‌: Adapted to concrete pump truck equipment, adopts double-layer wear-resistant structure, and the curvature radius of the bend is ≥1m to reduce the delivery resistance‌1. ‌Hose (delivery hose)‌: Specially used for pouring at the end of the pump truck, with embedded steel cord reinforcement layer, withstand -30℃~100℃ temperature, and have anti-kink characteristics‌7. ‌Core component composition‌ ‌Pipe body‌: The main material is Q235 straight seam steel pipe or 20#/35# seamless steel pipe, with a wall thickness of 4.5~6mm, and the inner wall is added with a 2~3mm wear-resistant layer through threaded welding technology, and the service life is increased by 2.5 times‌19. ‌Connectors‌: Flanges are divided into Type A (split type) and Type B (integral type), with thicknesses of 16mm/20mm respectively, ensuring sealing‌110. ‌Bends‌: The bending radius of the arm-specific type is 275mm±2mm, and the non-arm type provides standard angles such as 90° and 45°‌10.
