Product Overview
Ceramic patch lined wear-resistant pipe adopts Q235 / 20# seamless steel pipe as outer substrate. The inner wall is lined with 92% / 95% high-purity alumina ceramic patches, bonded and cured by high-temperature resistant inorganic adhesive with staggered arch tiling technology, forming a three-layer composite wear-resistant pipe. The alumina ceramic patch reaches Mohs hardness 9, HRA85-90, with much better wear resistance than ordinary steel pipe. The outer steel pipe bears pressure and impact load, while inner ceramic tiles resist particle scouring. It is suitable for large diameter pipes, elbows, tees and other special-shaped fittings. Damaged ceramic pieces can be partially replaced, which makes it a mainstream pipe for pneumatic ash conveying, mineral powder, tailings, sand and other high-abrasion dry material transportation.
Product Advantages
· ✅ Ultra-high wear resistance & long service life: High alumina ceramic features extreme hardness. Its service life is 10~20 times longer than ordinary seamless steel pipe under same working conditions, greatly cutting downtime maintenance.
· ✅ Smooth inner wall & low flow resistance: Low friction coefficient of ceramic surface prevents material accumulation and scaling, reducing fan energy consumption.
· ✅ Acid & alkali corrosion resistance: Alumina ceramic has stable chemical property, resisting acid, alkali and salt corrosion, suitable for working conditions with both abrasion and corrosion.
· ✅ Suitable for special-shaped fittings & large diameter: Elbows, tees, reducers and chutes can all be lined with ceramic patches, preferred solution for large-diameter wear-resistant pipelines.
· ✅ Partial repair available: Only replace damaged ceramic tiles instead of the whole pipe, lowering maintenance cost.
· ✅ Light weight: Lighter than bimetallic cast pipe, reducing support load and facilitating transportation & installation.
Product Structure
Three-layer composite structure, combining toughness and ultra-high wear resistance
· Outer Steel Substrate: Optional Q235 / 20# carbon steel or stainless steel. High pressure resistance, weldable and flange connectable to guarantee overall structural strength.
· Adhesive Layer: Special high-temperature inorganic adhesive with high bonding strength and anti-aging property, stable without debonding under -60℃~250℃.
· Inner Ceramic Patch Layer: 92/95 alumina corundum tiles, laid in staggered arch tiling to avoid straight gaps and prevent local damage caused by material scouring. Optional ordinary bonded type or stud-weld reinforced type for heavy impact conditions.
