Ceramic-lined pipes & elbows are the use of SHS – Manufacturing centrifugation, the melting point of alumina ceramic pipe in 2045 ℃, alumina layer and the steel layer structure due to process special reasons, the stress field is also special.
Wear-resistant ceramic composite pipe, full name ceramic liner composite steel pipe, is a kind of ceramic composite steel pipe.
The combination of high rigidity of ceramic and high elasticity of steel gives the pipe unmatchable features as an abrasion resistant, heat resistant and corrosion resistant material for use in the fields of power generation, metallurgy, mining, and chemical industry etc.
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.
There are probably hundreds of different methods for packing a abrasion resistant pipe and Elbows, and most of them have merit, but there are two principles that are vital for any method to work prevent rusting and Sea transportation security.
Ceramic-lined composite pipe is the use of "SHS- self- propagating high-temperature synthesis of centrifuge technology" made of new composite materials...
Ceramic Tile Lined pipes have very uniform coating of specially formulated ceramic material that is affixed to the inner of the pipe and gives a very smooth surface.
Our packing can meet any needs of the customers.
Self-propagating high temperature synthesis (SHS)is used to describe a process in which the initial reagents (usually powders), when ignited, spontaneously transform into products due to the exothermitic heat of reaction.
Ceramic Liner pipe is a high technology production technology-self-fuel high temperature clutch synthesis method.
1). High Abrasion Resistant:
Vickers hardness of the corundum lining is HV1100 to1500, as high as that of tungsten-cobalt hard alloys, and the abrasion resistance is 20 times as carbon steel pipes. The composite ceramic lined steel elbow was used in a mining plant for about fifty thousands hours. The general service life of common steel elbow is about 700 hours.
2). Corrosion Resistant:
Corundum is a neutral material, and is acid-proof and fouling -free.
3). Heat Resistant:
Ceramic lined composite steel pipe can work under circumstances of -50 to 800 Celsius degree .
4). Lower Weight and Convenient Installation:
The ceramic lined steel pipes are lighter than alloy pipes, cast iron pipes, and cast stone pipes and can be welded or connected through flanges, which reduces the expense of transportation and makes the pipes easier to install.
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 lined steel pipe is about 1/3 of the cast stone bent pipe's, 1/2 of the cast stone straight pipe's.

Hoop strength is the resistance against radial pressure. The strength of the ceramic -lined steel composite pipe is 300 to 500MPa.
Ceramic lined pipe's extension pipe draws
Conveying highly abrasive materials, steel piping systems are under constant attack often over long distances.
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.
