summary:
The lining of the steel steel composite bimetallic pipeline is made of wear-resistant cast steel, which not only has the wear resistance and corrosion resistance characteristics of high alloy cast steel (more than 30 times higher than that of 16Mn seamless steel pipe), but also has high mechanical strength and high impact resistance. The composite bimetallic is metallurgically bonded, making it safe and reliable to use.
Wear resistant cast steel is made of chromium based white cast steel, which is a type of cast steel with excellent wear resistance and has shown significant superiority in some applications. It is more suitable to use white cast steel under the conditions of corrosive media and particle erosion interaction. Under dry working conditions, wear is the main failure mode of the material, so a high chromium cast steel material that can obtain a martensitic matrix through heat treatment is selected.
The steel steel composite bimetallic pipeline is cast using the lost foam vacuum suction casting composite process. This composite process fills the gap in China's anti-corrosion and wear-resistant industrial transportation pipelines, and solves the problem that bent pipes cannot be combined. Bent pipes and other various shaped pipelines can be combined as a whole, changing the traditional method of using folded lines to make bent pipes and other shaped pipelines. It does not change the flow trajectory of materials in bent pipes, greatly reducing material transportation resistance.
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 molding process. The outer wall of the bent pipe adopts a hot bending bend, and the inner layer is cast with high chromium cast steel. Compared with traditional wear-resistant all gold cast iron, wear-resistant alloy cast steel, steel ceramic composite pipes, and cast stone pipes, this pipeline has many advantages.
characteristic:
1. Good wear resistance, fully utilizing the wear resistance and corrosion resistance of high chromium cast steel.
2. High pressure resistance, suitable for any pressure level, tightly combined with the inner and outer layers, using special technology to form a solution bond between the composite layers, ensuring the reliability of operation.
3. Has good resistance to mechanical and thermal impacts.
4. Easy installation and connection, can be cut and welded freely.
Application scope:
Blast furnace slag water system
Coal powder conveying system and dry ash conveying pipe in thermal power plants
Stone coal system in thermal power plant
Other powder pneumatic conveying systems

Hydraulic slag conveying system and slurry conveying with larger particle size.
