Ceramic Lined Pipe usage

The ceramic lined 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.

Ceramic lined pipe and the traditional steel pipe, wear-resistant alloy cast steel pipe, cast stone pipe and steel, steel and other rubber pipe is essentially different. Ceramic lined pipe is the outer layer of steel, the inner layer is corundum. Coral layer Vickers hardness of up to 1100-1500 (Rockwell hardness of 90-98), the equivalent of tungsten cobalt hard gold. Wear resistance than carbon steel pipe more than 20 times higher.

At present, the use of our company's high wear-resistant ceramic lined steel pipe dozens of thermal power plant practice shows that: ceramic lined steel pipe anti-wear ability, anti-fluid erosion ability.

In a duct, the elbow wear the fastest, in practice, Ceramic lined pipe used after 1 to 2 years to open the observation and measurement, the composite layer are no obvious wear or tear off, ceramic-coated steel pipe wear Than the thick-walled wear-resistant cast steel pipe increased by nearly 5 times.

Ceramic lined bend usage
Ceramic lined elbow usage

The ceramic lined elbow throughout the power, metallurgy, coal, petroleum, chemical, building materials, machinery and other industries, and high-speed development. When lining the wear-resistant ceramic elbow to deliver high grinding material (such as ash, coal, ore powder, etc.), there is a lining of wear-resistant ceramic elbow wear fast, especially the elbow Wear faster. When lining a The ceramic lined elbow to deliver a highly corrosive gas, liquid or solid, there is a problem that the lined wear-resistant ceramic elbow is corroded and is quickly damaged.

There is a problem that it is expensive to use a heat-resistant steel pipe when the material having a higher temperature is conveyed in the lining of the wear-resistant ceramic elbow. After lining the wear-resistant ceramic elbow, these problems are solved.

The ceramic lined elbow is widely used in wear and tear of the mine filling material, ore powder and tailings transport, coal-fired power plant powder, smelting, ash and other lined with wear-resistant ceramic elbow is also very appropriate.

The ceramic lined pipe, Elbows, Reducer, Tees 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 lined 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.

Coal preparation plant site

The cost per meter is equal to the unbent pipe's, 5%~15% less than the bent pipe's.

Abrasion resistant pipe in Dense Medium System

Serious wear and tear of the pipeline not only caused a lot of material waste and media running, running, dripping, leakage, and frequent pipeline maintenance replacement, increasing the labor intensity of workers, increased production costs.

电力行业耐磨管道的品种分类及代号

火力发电厂耐磨管道主要是输送原煤粉、灰渣、烟气脱硫(FGD)石灰石粉粒及浆液等,由于输送的介质流速快,运行工况恶劣,致使管道,特别是弯头、变径管严重磨损和腐蚀,不但消耗了大量的金属材料,也给火电厂安全、经济运行带来了隐患。管道的磨损机制是以冲蚀磨损为主。耐磨管道可分为两大类:单金属管道和复合管道。

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.

Abrasion resistant pipe specification, Standard and identification

Because the outer surface behaves like mild steel, the product can be cut and welded with proper procedure in the field, configured into a variety of fittings, and can accept the standard end options of flanges, weld rings and couplings.

Application of Abrasion resistant pipe

Abrasion resistant pipe applied in coal-fired power plant ash and slag discharge tube, powder, powder tube, desulfurization pipeline,in addition also widely used in the following industries:
