Import Alumina Insulation Tube — Buy in Bulk from Supplier in China

Alumina Insulation Tube from Lonci Group Co., Ltd. is a high-purity ceramic component engineered for extreme-temperature environments, particularly industrial furnaces. The tube is fabricated from high-grade alumina, delivering thermal shock resistance and structural stability at continuous operating temperatures above 1600°C. Custom sizing is available to match specific furnace configurations, ensuring precise fitment for threading or support roles in kiln structures.

The material composition is high-purity alumina, a standard ceramic grade known for its low thermal conductivity and high mechanical strength under load at elevated temperatures. Typical alumina content for such tubes ranges from 95% to 99.5%, with higher purity offering superior resistance to chemical corrosion and thermal degradation. The surface finish is usually unglazed to maintain thermal insulation efficiency, while dimensional tolerances align with standard ceramic industry practices for industrial applications.

These tubes are primarily used in metallurgy, ceramics, and glass manufacturing, where they serve as supports, spacers, or protective linings in high-heat zones. Buyers include furnace manufacturers, kiln operators, and thermal processing plants seeking durable, long-life components. Sourcing terms typically involve confirmation of exact dimensions, tolerances, and thermal performance metrics, with incoterms like FOB or CIF negotiated based on shipment volume and destination.

Lonci Group Co., Ltd. operates from No.2 Building, No.66 Shahe Road in Shanghai, China, specialising in ceramic materials for industrial applications. The company holds a harbor trust tier, indicating a baseline level of verification for its profile. While the response rate and average response hours are currently listed as zero, this may reflect recent updates to the supplier’s communication metrics rather than a lack of capability.

The supplier focuses on high-temperature ceramic products, with Alumina Insulation Tube as a key offering. The profile does not state explicit certifications, production capacity, or client references, so buyers are advised to request these details directly. The address and operational base in Shanghai suggest access to regional logistics hubs, which may benefit lead times for East Asian markets.
