Bimetal Clad Pipe is cast with mold vanishing vacuum suction casting cladding process.

Outer of straight pipe is common steel pipe, cladding realized by forming high chromium lining via centrifugal forming technique.

Bi-metal clad pipes are used in mining industry

Bimetallic connection:

Most of the outer tube is used galvanized pipe, followed by a galvanized pipe mature connection:

As shown in Figure 1, threaded connection (commonly known as thread connection), for DN15-DN100, the implementation of GB7306-2 and GB3287-1982 standards;

groove clamp connection, for more than DN100, the implementation of CJ / T156 standard;

flange connection, as the case may be, generally more than DN100, flange and so on by the manufacturers, and in the connection with a dedicated silicone layer;

As shown in Figure 4, welding connection, according to the actual working conditions using welding, the implementation of YB / T5092-2005 and JB / T4747-2002 standard, generally used three-layer welding, the first argon arc welding back cover, re-welding transition layer, the last manual arc Fill the filling surface.

Bimetal wear resistant pipe adopts centrifugal casting technology in the production process of straight pipe. This technology is to fuse and shape both metals in liquid state, realizing the purpose of real metallurgical bonding. The shear strength of the binding layer is higher than that of the metal itself, and completely realizes the mechanical complementarity between base layer and wear resistant layer.

Bimetal wear resistant pipe, including: double metal wear-resisting straight pipe and double metal wear-resisting bend, double metal wear tee, double metal wear resistance reducer adopts the pipe fittings such as vacuum suction casting composite process, its advanced technology, effectively solve the problem of the bent pipe cannot be composite, bending and other various special-shaped pipe can do the whole compound, don't change the material flow in the pipe bending trajectory, reduce resistance material conveying.

The outer wall of the centrifugal pipe is made of carbon steel, which ensures that the bimetal wear-resistant pipe has high mechanical strength and impact resistance.The inner lining wear resistance layer adopts the anti-wear alloy steel series independently developed by our company. The steel mainly adds alloy such as cr-ni-mo-cu-re and so on. Through the tempering heat treatment process, the alloy steel has strong wear resistance and corrosion resistance, high mechanical strength and impact resistance.

The whole set of process of our company is the first in China, which fills the blank of anti-corrosion and wear-resistant industrial pipeline in China and has reached the international advanced level. It has been widely used in mining, metallurgy, coal, electric power and other industries, and is an ideal wear-resistant pipeline.

Bimetal wear - resistant pipe advantages：

1. The hardness of a good wear resistance superhard wear alloy is greater than 56 (HRC), which has good wear resistance and thermal stability.

2. Excellent impact resistance, metal binding and thermal shock resistance KMTBCr28 bimetal composite wear-resistant elbow. The joint surface of the two metals is completely metallurgical, safe and reliable.The coefficient of thermal expansion is equal to that of expansion, shrinkage and crack.The outer wall of the elbow is made of steel tube and the inner lining is made of super-hard wear-resistant alloy.

3. Good resistance to heat and corrosion. The matrix of super hard alloy material has strong resistance to heat and corrosion.Under the action of wet state, corrosion medium and particle scour, it is more suitable to use the superhard wear-resistant alloy.Under the condition of dry state in which abrasive wear is the main failure mode, a kind of superhardness wear-resistant alloy material which can be obtained by heat treatment is selected.

4. The bimetal wear-resistant pipe with low composite cost and good quality is manufactured by the internationally advanced epc casting process with high yield, good compactness, uniform thickness and stable quality.

5. The bimetal wear-resistant pipe can be connected by flange, quick joint and direct welding.In addition, due to the high resistance and beating performance of the composite pipe, when partial blockage occurs in the pipe system maintenance, it can be knocked or hammered at will, and can be cut, unloaded, welded and installed at will.
