Wear-resistant ceramic tube of purchasing and its advantages

The advantage of wear-resistant ceramic tube:

1, run small resistance 

CHEMSHUN ceramic tube due to the inner surface is smooth and durable, also don't like seamless steel pipe inner surface with convex spiral exists.By the relevant inspection test unit internal surface roughness and water resistance properties, its surface smoothness is better than any metal pipe, qing drag coefficient is 0.0193, slightly lower than the seamless tube.So the tube has the characteristics of running resistance small, can reduce the operation cost.

2, wearability 

ceramic tube due to the lining layer of corundum ceramics (a - AL2O3), mohs hardness can be equivalent to 9.0 HRC85 above.So for metallurgy, electric power, mine, coal and other industries transport by grinding medium has high wear resistance.Confirmed by industrial operation: the wear life is ten times the hardened steel or even dozens of times. 

3, long service life due to the ceramic layer for steel (a - AL2O3), neutral.So the acid and alkali resistance and seawater corrosion, and also has the characteristics such as scale, can prolong the service life of pipelines. 

4, good heat resistance performance as the corundum ceramics (a - AL2O3), for a single stable crystalline state organization.So the pipe can be in - 50-700 ℃ temperature range of normal operation for a long time.Material linear expansion coefficient of 6-8 x 10-6/0 - c, about half of the steel pipe.Material has good thermal stability. 

5, low engineering cost ceramic composite tube light weight, appropriate price.Than with the inner diameter of cast stone pipe light weight 50%;Than wear-resistant alloy tube light weight 20-30%, and good abrasion resistance, corrosion resistance, because the service life is long, thus a hanger cost, handling, installation and operation cost is reduced.By the relevant unit engineering design institute and construction budget compared with the engineering practice, the pipe construction cost with cast stone, compared with wear-resistant alloy pipe, engineering cost by 20% or thereabouts. 

6, installation is convenient due to the tube light weight, and good welding performance.So can be connected by welding, flange, quick, convenient installation, construction and reduces the cost of installation.

Wear-resisting bend procurement guidelines:

Now everybody of wear-resisting bend has a preliminary understanding, first it good abrasion resistance, heat resistance performance is good, is a neutral corrosion resistance is strong.thenIf it's the same kind of material of elbow, specific should decide what size of?Below I to tell you something very subtle: the same material of the same calibre elbow, the greater the bending radius of the medium Yin force is smaller, the longer service life.

The same material under the condition of the same bending radius,The larger the diameter of conveying medium Yin force is smaller.In this special remind the masses of users, if the absence of specific requirements, as far as possible choose caliber,Slightly larger bending radius elbow, this seemingly increase the cost, can reduce maintenance costs in the actual operation, shutdown replace piping losses, it is the best policy.   

Short radius elbow medium flow resistance is big, long radius elbow resistance is smaller. Pipe lined with alumina ceramic, with its high wear resistance, high hardness, good oxidation resistance, corrosion resistance and high strength of high and low temperature resistance,Has become a kind of the most widely used wear-resisting material, the world's special ceramics to about 80% of market share (wear-resisting material).
