Product Name: Wear-Resistant Steel Tube
Introduction
Wear-Resistant Steel Tubes are engineered hollow sections manufactured from high‑hardness, abrasion‑resistant steels (e.g., AR400, AR500, 27 % Cr) that combine tubular form-factor with exceptional longevity in erosive or sliding wear environments. Through controlled alloying, quench‑and‑temper heat treatment, and precision rolling or welding processes, these tubes deliver superior surface hardness and core toughness-ideal for applications where internal or external wear significantly reduces service life.

Features & Advantages
Exceptional Abrasion Resistance: High hardness surface (Brinell 400–550) resists material loss under sliding or impact wear.
Tough Core: Quench‑and‑temper process ensures inner toughness to prevent brittle failure under stress.
Uniform Properties: Seamless or post‑heat‑treated welded construction delivers consistent hardness and strength throughout.
Formability & Fabrication: Tubular geometry allows rotation, bending, and welding into wear liners, cyclones, and pipe spools.
Extended Service Life: Dramatically reduces downtime and maintenance costs in abrasive flow applications.
Applications
Mining & Aggregates: Chute liners, wash‑plant spools, and slurry pipelines conveying ore and grit.
Cement & Construction: Kiln down‑pipes, classifier ducts, and mill discharge spouts.
Power Generation: Coal-feed tubes, ash‑handling lines, and cyclone separators.
Industrial Pumps & Valves: Wear sleeves, neck tubes, and erosion‑resistant pipe fittings.
Material Handling: Screw‑conveyor housings, drop‑through chutes, and bucket‑elevator casings.
Packaging & Delivery
Bundling: Tubes bundled by size and grade; strapped with steel bands; plastic or metal end‑caps to protect bore.
Skidding: Loaded on treated wooden skids or steel cradles; secured against movement in transit.
Surface Protection: Optional rust‑preventive oil or phosphate coating; shot‑blast cleaning if required.
Lead Time: Standard production and shipment within 20–30 days; expedited schedules (10–15 days) available for urgent orders.
