High Hardness Alumina Wear Resistant Ceramic Lined Bend for Coal Transport
Wear resistant ceramic tiles lined pipe
Our solutions is based on the thousnad of hundred applications in different industries.we know well about the pipe abrasion problems. We can meet the customer’s requiment as well as help them saving cost.Meanwhile, we focus on the industries’processing, providing the suitalbe products which are tested good and reliable.
Ceramic tile lined pipes introduction.
Pipes used in the heavy industries are suffering from hight temperature(Mormally above 100℃),high wear,high impact, expecilly the bends. We developed the ceramic tiles lined pipings for this application.
This kind of pipe composite three parts, the steel pipe+glue+ceramic.The steel pipe is hot pressing,which is different to section welding bend. The ceramic tiles is 95% high alumina, and the glue is high temperature adhesive up to 350OC.This kind of bend are good for the powder transport and no tile fall off or aging working under 350OC for long time. The service life span is 4 to 5 times than normal steel pipe.

Installation:
Ceramic pipe and ceramic pipe connected Ceramic pipe and normal pipe
by flanges,keeping the DN size. connected by flanges.
Application advantage:
n Super wear resistant, High density. 95% high alumina and forming by 100 tons dry pressing machine.
n The steel bend is hot bended,no welding.
n Using the high quanlity glue, can protect the ceramic tiles from fall off.
n The bend is hot processing. No welding.
n Smooth inner wall of the pipe. It is good for bulk material transport, can reducing the waste

Product features:
Kingcera ceramic is made with 95% high alumina and 2% chromic oxide .The alumina powder is forming by dry press and fired by 1700OC temparature.The final tiles is pink.The ceramic has the high density and very abrasive
Alumina ceramic tile Ceramic lining
It has the following features:
n High hardness
Rockwell hardness is HRA85-90,next to the diamend hardness.
n Very good wear resistant quality
It is tested the ceramic wear resistant quality is more than 10 times than the normal steel pipe
n Good Impact quanlity
Our ceramic is toughened. Incerased the ceramic impact ability.
n No fall off of the ceramic
Using the high quanlity glue, can protect the ceramic tiles from fall off.
n Low density
Ceramic density is 3.6/cm3,only half to the steel density. Wear resistant ceramic to replace other bulky can greatly reduce the equipment load.

Special bond for Abrasion-resistant Ceramic Example for bond GWJ-350
GWJ-350 high-temperature-resistant inorganic bond is a patent product of our company. This bond, which is used to affix steel and ceramic, has high strength and temper as well as excellent heat resistance and aging resistance, and can solidify in room temperature. It is mainly used to affix abrasion-resistant ceramic patches in the wind feeding equipment, and convenient and flexible construction is its advantage. It has been proved by the operation for more than ten years that, this technology is mature and reliable, which can be used in a temperature of -50℃~300℃ in long term or in a temporary temperature of 350℃ temporary without aging and peeling, thus most requirements of the wear resistance construction can be satisfied.
