The Ceramic tile lined pipe spool is composed by steel pipe, adhensive and abrasion-resistant ceramic, we use 20 # seamless steel pipes shaping with hot bending (it is different from centrifugal casting or steel plate rolling), the ceramic tiles bonding with GWJ-350 high temperature-resistant inorganic adhesive which was developed by TsingHua University and affix abrasion-resistant ceramic in the steel pipes, we use miss match installation instead of directly bonding (this technology was used in the bridge building a thousand years ago), and forms a firm wear-resistance layer after heating solidification. Ceramic tile lined pipe spool is applicable for the pneumatic powder-feeding, and can be used under a temperature of 350℃without aging and peeling for long life. The service life is 4-5 times than the normal abrasion-resistant pipes.
Advantage
- Super wear-resistant, high density: we use 95% of chromium corundum, 100 tons dry-pressing.
- Elbows formed by hot-bending, the outside of the bending part are seamless which is wear-resistant and can prolong the service life.
Firmly bonding without pealing: we use epoxy adhesive and miss-match installation technology, so that there is no straight-seam. - High temperature and ageing resistance: we abandon the traditional organic bond, and use inorganic bond which is ageing resistance.
High pressure resistance: We use 20# seamless steel pipe, which is high pressure resistance and avoiding welding leakage. - The pipe with smooth inner wall which can make the materials flow smoothly: we use seamless steel pipes which has smooth inner wall that can reduce weariness, and the height tolerance of ceramics is below 0.5mm.
Application Guidance
- Avoid welding on site, the welding layer should be 30mm above the ceramic layers; according to our experiences, if you need a shot welding (for example spot welding) or must welding, watering after welding, which will reduce the damage of the adhesive layer.
- Avoid striking and throwing the pipes during transportation and installation.
- To achieve the best abrasion-resistant solutions, thicken ceramic liners can be used in the elbow which has serious abrasions.
Features
Ceramic tile lined pipe is our company to absorb similar products at home and abroad on the basis of advanced technology developed a shell for the steel body, within the wear-resistant ceramic tube of the new composite pipe products, with high wear resistance long service life And so on
The use of anti-off porcelain tube, porcelain tube mosaic, so that paste more flat, more solid with a strong inorganic adhesive paste, wear-resistant steel bowl welding, porcelain and steel body combined to form a double reinforcement to ensure that the porcelain tube does not fall off. The installation of flexible, high wear resistance, processing convenience, the cost is moderate.
High hardness
Rockwell hardness of high alumina ceramics is up to HRA80-90 which is second only to diamond and far exceeds wear-resistant steel stainless
Excellent wear resistance
The wear resistance of high alumina ceramics is 266 times that of manganese steel and 171.5 times that of high chromium cast iron. According to our investigation & follow-up to the clients, the service life of equipment can be prolonged over 10 times under the same working conditions.
Corrosion resistance
High alumina ceramics are inorganic oxides with extremely stable molecular structure and no electrochemical corrosion, thus they can resist erosion of acid, alkali, salt solutions and organic Solvents.
Thermostability
Working temperature of high alumina ceramics can be as high as 1400℃.
Good self-lubricity
High alumina ceramics have the properties of self-lubricity and in adhesion, the roughness is only 1/6 that of steel pipes thus less flow Resistance.
Light weight
The density of high alumina ceramics is about 3.6g/cm3, which is only half that of steel, thus easy for construction and installation.
