The pulverized coal pipeline is used to transport high-temperature gas mixed with hard particles. Its operating characteristics are high temperature, high flow rate, high particle hardness, and serious equipment wear, especially the elbow part, without any protective measures. Put on. Most of this equipment is mounted on high-altitude supports, which are inconvenient for maintenance. Once worn out, the safe use of the equipment will be seriously affected.
The service life of the pulverized coal conveying pipeline is greatly improved after being lined with wear-resistant ceramics. The corundum ceramic lining is a material with wear resistance, high-temperature resistance, high hardness, acid and alkali corrosion resistance, and very high thermal stability. The steel pipe is bonded by wear-resistant ceramic adhesive, which is convenient for construction, has high bonding strength, and the lining is smooth and does not accumulate material.
Ceramic pipes are lined with corundum ceramics, which is generally ten times or even dozens of times that of ordinary steel pipes, and has a qualitative leap in wear resistance with wear-resistant alloy cast steel pipes and cast stone pipes. The service life of ordinary steel pipes is half a year to one year, and the service life of wear-resistant ceramic pipes can reach 5 to 10 years, which greatly reduces the number of equipment downtime and maintenance, and saves a lot of manpower and material costs for enterprises. It is a very cost-effective anti-wear scheme for pulverized coal conveying pipelines.
