Product content
The cermet-lined composite pipe has wear resistance, corrosion resistance and heat resistance, so it can be widely used in power plant coal, ash, mine ore powder, tailings, backfill, coal, coking particles, combustion For the transportation of factory materials, the steel pipe has high strength, good toughness, impact resistance, good welding performance, and high hardness, high wear resistance, corrosion resistance, and heat resistance of corundum porcelain, which overcomes the low hardness of steel pipe, poor wear resistance and poor ceramic toughness The characteristic is an ideal wear-resistant pipeline.

Note: ①The pipeline of the mine's gravity separation workshop, the ore size is less than 2mm, and the weight concentration is 30%
②Ceramic steel pipe outer diameter φ245, thickness 8mm, ceramic layer thickness 4mm, 20# carbon steel pipe thickness 9mm
③This comparative test is still ongoing, and the ratio of 175 is only based on the estimated data of three years of practice
