The Armored Ceramic Ring Pipe for mining slurry, DN100-DN800, is a high-performance pipe designed specifically for transporting mining slurry. The following is a detailed introduction:

Structure and Materials

Armored ceramic ring pipe typically features a composite structure consisting of a ceramic inner lining and a metal outer layer. The inner lining is typically made of corundum ceramic (Al₂O₃), which offers high hardness, high wear resistance, and excellent corrosion resistance, with a Mohs hardness of up to 9.0, equivalent to HRC90 or higher. The outer layer is a steel pipe, providing high strength and excellent toughness, ensuring the overall strength and impact resistance of the pipe. The two are tightly bonded by a transition layer to form a sturdy armored structure.

Specifications

DN100: The outer diameter of the pipe is generally 108mm. The ceramic layer thickness is typically no less than 3mm. The outer steel pipe thickness can be selected according to actual requirements, such as 5mm. Lengths can be customized to meet project needs; common lengths include 1000mm, 2000mm, and 3000mm. DN800: The pipe's outer diameter is approximately 835mm. The ceramic layer is ≥4mm thick, while the outer steel pipe is relatively thick, such as 16mm. Lengths can also be customized, with 2000mm being a common option.

Performance

High Wear Resistance: The Ceramic Lining achieves a microhardness of HV 1000-1800, making it ten times more wear-resistant than hardened medium-carbon steel and superior to tungsten-copper carbide. It effectively resists erosion and wear from solid particles in mining slurries, significantly extending the pipe's service life.

High Corrosion Resistance: Corundum ceramic is a neutral material with stable chemical properties. It is resistant to various inorganic and organic acids, as well as organic solvents. It offers excellent resistance to corrosive substances found in mining slurries, with corrosion resistance exceeding ten times that of stainless steel.

Excellent Impact Resistance: The outer steel pipe provides the pipe with excellent impact resistance, enabling it to withstand the transient impact forces experienced during mining slurry transportation and preventing the ceramic lining from cracking or falling off. Low operating resistance: The ceramic-lined pipe has a smooth inner wall with a much lower roughness than metal pipes. Its clear water resistance coefficient is 0.0193, reducing slurry flow resistance within the pipe and lowering transportation energy consumption.

Connection Method

Typically, it utilizes butt-weld flanges in accordance with HG/T 20592 (PN16/PN25) or ASME B16.5 standards. Flanges are made of Q345B or 16Mn and are equipped with high-strength grade 8.8 bolts and rubber asbestos gaskets to ensure connection strength and sealing, facilitating on-site installation and maintenance.

Application Scenarios

It is primarily used in the transportation of slurry materials such as slurry, tailings, and concentrate powder in the mining industry, such as in mine backfilling and tailings discharge. It effectively reduces pipe wear and corrosion, reducing pipe replacement frequency and maintenance costs.
