Product Description

Qijing industrial ceramics are widely used in power, coal, metallurgy, chemical industry and other industries. As an abrasive material and corrosive medium.Qijing Industrial Ceramics is an ideal wear-resistant and corrosion-resistant pipeline, used to transport sand, coal, ash and aluminum liquid, and is suitable for different high-temperature pipeline inner diameters.In addition to the ash removal, slag discharge pipe, powder feeding and powder returning pipes of coal-fired power plants, ceramic-lined wear-resistant steel pipes are also widely used in the following industries:1. Mine:1. 1Coal water slurry, coal washing slime, mine filler, pulverized coal in the coal industry1. 2Metal mines: pipeline transportation of concentrates and tailings.2.1 Metallurgy:2. 2The blast furnace coal injection and slag conveying pipelines in iron and steel plants2.3 Optimal pipelines for steel-making conveying ferroalloys and refining outside the furnace.3. Cement plant. Photo show Ceramic pipe advantages:

1. High hardness
2. Superior abrasion
3. Corrosion and chemical resistance
4. Light weight
5. Low maintenance cost: Super wear-resistance reduce the maintenance frequency and also the maintenance cost.
6. Good fluidity : Smooth surface ensure the free flow of material without blocking

Transport and installation precautions:Matters needing attention for transportation and installation of ceramic pipe1. The ceramic composite pipe has high hardness and good toughness, but it should be put gently in the process of transportation and installation to avoid serious collision, especially to avoid direct contact with metal instruments or impact on the ceramic layer on the end surface.2. The qijing bending pipe is installed with directivity. When the bending pipe is installed, the direction indicated by the arrow on the surface of the bending pipe should be consistent with the flow direction of the conveying medium.3. When installing the pipe, the pipe should be aligned with the center line and level should be adjusted to make sure that both ends meet accurately.The displacement of both ends should be controlled within 1.0mm.4. When the flexible pipe joint is used to connect and install the pipe, the inserted lengths of both ends of the flexible pipe joint shall be adjusted symmetrically.Since the thermal expansion coefficient of the composite pipe is about 1/3 of that of steel, the expansion clearance can be reduced by 3-5mm.5. When using flange connection, the flange end shall be flush with the end of the composite pipe.6. Due to the excellent welding performance of the composite pipe, the pipe connection can be conducted by welding. However, when welding, 45o-60o "V" type slope Angle is 2-4mm and gap is 0.8-1.2mm.Packaging
