The cladding wear-resistant pipe is a composite pipe in which a high-hardness alloy layer is deposited on the surface of the steel pipe through the cladding process. Its core advantage lies in combining the toughness of the carbon steel matrix with the high strength of the wear-resistant layer, which significantly improves the wear resistance.
The cladding wear-resistant pipe is based on carbon steel such as Q235 and 16Mn, and a wear-resistant alloy layer is deposited on its inner or outer wall by CNC fully automatic cladding equipment.
hromium carbide alloy: The hardness of the cladding wear-resistant pipe reaches HRC58-64, and the wear resistance is 20-30 times that of ordinary steel pipes. It is suitable for high abrasive wear environments (such as mine tailings transportation);
High chromium cast iron: The cladding wear-resistant pipe contains 25-35% Cr, forming a network carbide structure with excellent impact resistance. It is often used for ash removal pipes in thermal power plants.
Nickel-based alloys: Wear-resistant cladding pipes maintain stability in high temperatures (above 800°C) and corrosive environments, making them suitable for the chemical industry.
The cladding layer and the base material form an atomic-level metallurgical bond, with bond strength far exceeding that of centrifugal casting or rubber lining processes, eliminating the tendency of traditional composite pipes to break apart.
he wear-resistant cladding pipe is cut by plasma cutting or carbon arc cutting, and the groove angle is controlled at 30°-45° to ensure that the penetration depth meets the standard during subsequent welding and avoid incomplete penetration defects.
Welding parameters: current 200-300A, voltage 22-28V, interpass temperature ≤150℃, slow cooling after welding to relieve stress
