Bimetallic composite wear-resistant pipe

The inner lining of the steel-steel composite bimetallic pipe is made of wear-resistant cast steel. This product has the wear resistance and corrosion resistance of high-alloy cast steel (wear resistance and corrosion resistance are more than 30 times higher than that of 16Mn seamless steel pipe), and has high mechanical strength and high impact resistance. The composite bimetal is metallurgically combined and safe and reliable to use.
Wear-resistant cast steel uses chromium-based white cast steel, which is a cast steel with good wear resistance. It has shown significant advantages in some occasions. For conditions where there is a mutual interaction between corrosive media and particle erosion, it is more appropriate to use white cast steel. Under dry working conditions, the material is mainly failed by wear, so a high-chromium cast steel material that can obtain a martensitic matrix through heat treatment is selected.
Steel-steel composite bimetallic pipes are cast using a lost foam vacuum casting composite process. This composite process fills the gap in my country's anti-corrosion and wear-resistant industrial pipelines, and solves the problem that elbows cannot be composited. Elbows and other special-shaped pipelines can be composited as a whole, changing the traditional process of using folding lines to make elbows and other special-shaped pipelines. It does not change the flow trajectory of materials in the elbows, and greatly reduces the resistance to material transportation.
Steel-steel composite bimetallic pipeline is a new type of wear-resistant pipeline developed by our company. The outer layer of the straight pipe is made of ordinary steel pipe, and the high-chromium cast steel lining is formed by centrifugal forming process. The outer wall of the elbow adopts hot-simmered elbows, and the inner layer is cast with high-chromium cast steel. Compared with the traditional wear-resistant alloy cast iron, wear-resistant alloy cast steel, steel-ceramic composite pipe and cast stone pipe, this pipeline has many advantages.

Features
1. Good wear resistance, giving full play to the wear resistance and corrosion resistance of high-chromium cast steel.
2. High-pressure bearing, suitable for any pressure level. The inner lining is tightly combined with the outer layer, and a special process is adopted to form a solution connection between the composite layers, which ensures the reliability of operation.
3. Good resistance to mechanical shock and thermal shock.
4. Easy to install and connect, can be cut and welded at will.
