Double‑Layer Wear‑Resistant Concrete Pump Elbow
Double‑Layer Wear‑Resistant Concrete Pump Elbow Double‑layer wear‑resistant elbow is core wear‑part for concrete pump trucks. It adopts composite twin‑wall structure: high‑chromium wear‑resistant inner liner resists friction from concrete aggregate, while outer carbon steel layer bears working pressure and mechanical impact. Compared with ordinary single‑layer elbows, it achieves much longer service life and lowers your replacement frequency and cost. Each double‑layer elbow goes through strict production flow, including raw material inspection, precision cutting, double‑layer nesting, full penetration welding, high‑temperature heat treatment and hardness test. Its service life can reach up to 60000 cubic meters of concrete delivery. We provide full specifications: DN100, DN125, DN150, available angles 15°, 30°, 45°, 90°. Compatible […]
