The liquid pipe transport has been widely used in the industries of electric power, metallurgy, coal, petroleum, chemical engineering, building materials, mechanism and so on. And it has developed rapidly. When transporting the materials with the harder abrasion (such as ash dregs, slag, coal powder, mining dregs, the rest mines, cement, etc), it will exit the problem that the abrasion of pipes is too rapid. Especially, the abrasion of bent pipes is greatly more rapid. When transporting the special abrasion materials or erosive materials, it will exit the problem that the damage of pipes is too rapid.
When transporting the materials with comparatively high temperature, it will exit the problem that the anti-hot steel pipes are very expensive. Since the ceramic steel pipe has gone into the market, the above problems have been settled down easily. The ceramic steel pipes are widely used for the transporting of mining fillings, mining power, and the rest mines with hard abrasion; for the pipe lines of hardening slag, blast furnace dregs, steel-making red-clay, agglomerated whitewash, dust cleaning of steel & iron companies; for the pipe lines to transport powder, to clean dregs, to clean sulfides, to clean dust for the thermal power plants; for the transport pipe lines of green stock, clinker, cements, coal powder and collective dust in the industry of cement. The ceramic steel unbent pipes are also the ideal pipelines for transporting the materials with erosive matter.
The ceramic steel unbent pipes, the ceramic steel bent pipes, reducers, three-path pipes, four-path pipes, multi-path pipes and others manufactured in our factory have been used in over 200 thermal power plants, more than 50 mines and the industries of coal, building materials, mechanism, petroleum and so on. For example, in the condition of hard abrasion, the ceramic steel unbent pipes have been used for several years. But, at present, there is no any ceramic steel unbent pipe has been worn through. Even the ceramic steel unbent pipes with hardest abrasion, their use life is 10 times longer than the cast stone bent pipes and wearable alloy steel bent pipes, 15 times longer than the toughened plastic bent pipes and toughened latex bent pipes. The ceramic steel pipe has captured the market rapidly. Besides the high quality and the wonderful capability, it's also because its capability price ratio is higher than other wearable, anti-abrasion & anti-hotness pipes.
For the pipes with the same sizes, types and length, the weight of ceramic pipe is about 1/2 of the wearable cast alloy steel pipe's, while the cost has reduced 10%~20% per meter; the weight of ceramic pipe is about 1/3 of the cast stone bent pipe's, 1/2 of the cast stone unbent pipe's.
The cost per meter is equal to the unbent pipe's, 5%~15% less than the bent pipe's.
Remarks:
1． Under the direction of the arrow diagram for the export direction.2． Bend radius is usually 1.5-5 times the diameter of steel pipe (1.5-5D).
3． Othe specifications of the compsite pipe can be manufactured accord to the user requirments.
4． The weight is caculate by theoretics, maybe have some tolerance, the real weight will be weigh in afer them finished.
Hoop strength is the resistance against radial pressure. The strength of the ceramic -lined steel composite pipe is 300 to 500MPa.
