AL2O3 wear and corrosion resistant seamless steel pipe consist of
three parts (steel pipe + adhesive + ceramic tiles), the steel pipe
is made of seamless carbon steel pipe. Abrasion resistant ceramic
tile lined steel pipes are 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.

To achieve the best abrasion-resistant solutions, thicken ceramic liners can be used in the elbow which has serious abrasions.
Ceramic tile lined wear-resistant multi-pass pipe fabrication technology principle, special corundum ceramics, made from Al2O3 as raw material, with rare metal oxides as solvents, and sintered at high temperature by 1730 ℃, are combined with wear-resistant ceramic pieces and block bricks in the pipe wearing surface through bonding, welding, inlay, riveting and socket technology. Thus forming a surface with excellent abrasion resistance, and the matrix still uses the composite pipe of the ordinary metal material.
According to different needs of the choice of wear-resistant ceramic patches, to meet the special needs of users of technical conditions. Compared with the traditional all-metal high alloy pipe fittings, the working face has higher abrasion resistance, which can make the whole wear-resistant and anticorrosion service life of the pipe increase several times to dozens of times times. Overall weight of the first mate down, reduce the amount of steel, reduce the cost of equipment and maintenance costs, improve economic efficiency.

Metals have good ductility but poor resistance to abrasion - which
means that abrasion prevention is required when metal pipes are
used in high-temperature fluid catalyst service. On the other hand,
ceramics possess great hardness and abrasion resistance, but they
are brittle. Metal Ceramic double pipe is a hybrid pipe using metal
as an outer pipe and a ceramic material for inner pipe segments,
applied together to utilize the two materials´ advantages. Hence
excellent wear-resistance and good corrosion resistance of the
ceramics and high strength and toughness of metal can be well
combined to get a comprehensive advantage of wear-resistance,
corrosion-resistance and anti-scaling. They are suitable for
applications in heavy wear working conditions. Ceramics are among
the hardest materials available and provide ultimate wear
resistance in piping. In high wear applications, ceramic lined
pipes have been demonstrated to be cost-effective by increasing
service life and reducing maintenance costs. Sunny Steel supply
ceramic lined abrasion resistant steel pipes to your custom
dimensions and budget. Our ceramic linings are the highest quality
materials available to ensure that we provide the most
cost-effective solutions for our clients.
The features of Weldable ceramic tile lined pipe are as follows:
Weldable ceramic tile lined pipe is usually used for high temperature and high abration material transport system.
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.
Ceramic tile lined pipe is composed of three layers: outer steel pipe layer, corundum layer, and ceramic glue layer. The inner ceramic layer is white from the surface. The ceramic is generally 95% ceramic, and the temperature is generally below 200°C.
At present, the common ceramic sheets lined with ceramic composite pipes are: ceramic block, dovetail mutual pressure, welding type, mosaic, card slot and so on. It has the characteristics of wear resistance and long service life.

Ceramic tile technical indicators
Bimetallic composite steel pipe basic principles: outside the tube is responsible for the pressure and the role of rigid support pipe, liner bear the role of corrosion resistance.
The outer tube can be used according to the flow and pressure requirements of the conveying medium, choose the carbon steel pipe with different diameter and wall thickness, hot-dip galvanized steel pipe, straight seam welded pipe, spiral pipe, low pressure medium pipe, high pressure boiler, Oil cracking with seamless pipe, pipe and so on. Diameter from φ20-φ1020mm, wall thickness from 2.5-50mm.
Can be austenitic stainless steel 304,304 L, 316,316 L, copper-based alloy, nickel-based alloy, Hastelloy, titanium, titanium alloy, duplex stainless steel and other new high corrosion resistance alloy material. The lining wall thickness can be based on service life and welding process requirements from 0.3-4mm.
Will be assembled inside and outside the tube placed in the sink, the cluster of explosives placed in the lining liner axis, through the explosive instantaneous production of explosive force, causing the water pressure within the tank increased instantaneously, instantaneous increase in water pressure, Tube in the direction of outward expansion, outward expansion of the liner under the action of water pressure, the expansion of the outer surface of the outer tube, and under the action of water pressure, with the external tube continued to expand until the pressure disappeared ; And the outer tube in the axial direction inward contraction, the final composite forming.
