Pipes below Ø89mm are collectively referred to as small-diameter pipes. Compared with large-diameter pipes, the average cost of small-diameter wear-resistant ceramic pipes is much higher than that of large-diameter wear-resistant ceramic pipes. Why is the production cost of small-diameter wear-resistant ceramic pipes relatively high? We analyze from the following aspects:
The casting process of the outer steel pipe of the small-diameter wear-resistant ceramic pipe is more complicated, and the output is much lower than that of the large-diameter steel pipe;
The inner diameter of small-diameter wear-resistant ceramic pipes is usually less than 80mm, and it is difficult for construction technicians to paste the porcelain by hand. If the pipeline is long, it needs to be cut off and then welded after the porcelain is pasted. The construction is difficult and the construction process is more complicated;
If small-diameter wear-resistant ceramic pipes do not want to be cut off, more expensive wear-resistant ceramic materials, such as ceramic rings and integral ceramic pipes, are usually used, and the production cost is higher;
If the small-diameter wear-resistant ceramic pipe is an elbow or a tee, it usually needs to customize a special ceramic ring and an integral ceramic pipe, and the mold cost is high;
In summary, the reasons for the higher cost of small-diameter wear-resistant ceramic pipes are the complex casting process of external steel pipes, low output, and the construction of internal wear-resistant ceramic materials is difficult and material costs are higher.
