Steel-high chromium bimetal wear-resisting compound pipe exterior wall uses the ordinary seamless steel tube, through the centrifugal forming process forms the high chromium cast steel lining compound. The outer wall of the elbow is heated and the inner layer is made of high chromium cast steel, which has the wear-resisting property of high alloy cast steel, and can withstand pressure and has higher mechanical properties.

Special Corundum ceramics made of rare metal oxides as solvents and sintered at high temperature by 1730 ℃ through bonding, welding, mosaic, riveting and socket technology, a variety of wear-resistant ceramic pieces, block brick materials in the pipe wear surface, so as to form a surface with excellent wear resistance, and the matrix is still using the composite pipe of ordinary metal.

Usage

Bimetal wear-resistant pipes are widely used in coal washing plants, thermal power plants, steel plants, cement and other industries.

High abrasion resistance

The hard quality of high chromium cast steel is M7C3 type carbide, which has high toughness and high hardness (hv1500-1800) and thus has good wear resistance.

The compound technology is advanced and stable

High precision of mould making, wear-resistant layer thickness uniformity, and uniform, stable performance, especially for straight tubes and special-shaped tubes for the overall composite (elbow, tee, four-pass, tapered pipe, variable diameter pipe, non-thick wall pipe, eccentric tube can do the whole compound).

Good thermal shock resistance

As the main product of the internal and external thermal expansion coefficient is similar to the temperature of the rapid changes and often changing conditions, will not occur due to the loss of the inner layer of failure.

Bimetal wear resistant pipe fittings are suitable for copper mines

Strong corrosion resistance, high temperature, wear resistance

Because of the composition and structure of Ka carbide and the high content of CR, the matrix has high heat resistance and decay performance, and can show corrosion resistance in high temperature or corrosive environment. Under the condition of wet state, corrosive medium and particle scouring, the 28Cr white cast steel used in cast mode is used. In dry condition, high chromium cast steel material with martensite matrix can be obtained by heat treatment.
