Wear-resistant alloy composite pipe Features
A good overall performance
Composite pipe outer wall with steel , lined with high-chromium alloy , the two formed a good metallurgical bond , both high alloy materials for wear and corrosion resistance properties, but also high mechanical strength and less high impact resistance , to solve a single material can be difficult to reconcile the contradictions and abrasion resistance welding , the material play to the best level of performance advantages, the use of safe and reliable.
2 high wear resistance
The composite wear layer composite pipe of high -chromium alloy , containing about 45% of the organization of the hard carbide M7C3 type , since this structure Ka rod- type carbide , and it has a high toughness ; while Ka macrohardness carbide micro- hardness is high (HV1500-1800), in the wear layer above HRC55 , so good wear resistance .
3 corrosion resistance , high temperature performance
Since the composition and structural characteristics Ka carbide substrate and the Cr content of the solid solution has a strong heat resistance, corrosion resistance , high temperature or corrosive environment can show good corrosion resistance, wear resistance.
4 advanced, stable composite technology
The wear-resistant pipe and elbow by LFC vacuum casting composite manufacturing process, namely F casting method , with the manufacturing process of composite wear-resistant pipe has the following characteristics :
( 1 ) The process is simple , easy to operate production yield.
( 2 ) Since the process is characterized by high precision tooling size , using an inner tube lined with real high vacuum in the tube by suction casting , so the product , the precise size , density is good.
( 3 ) using the method of vacuum casting process F resistant alloy composite pipe production and elbow, homogeneous and stable performance. Does not appear , cracks holes and other phenomena .
5 , good thermal shock performance
Since the inner tube composite wear , thermal expansion coefficient of the outer layer equivalent to a high level and constantly changing rapidly changing conditions occasions inner fragmentation does not occur , the phenomenon of early failure occurred small pipe system running resistance, beautiful appearance beauty .
6 . Transportation, installation and ease of use
Alloy composite pipe and elbow quick connector or flange can be welded directly mounted . As the fight against high- performance composite pipe , the pipe diversion occurs when a partial plugging free to percussion , arbitrary cutting , unloading change , installation , maintenance is very convenient.
alloy composite wear-resistant pipe applications
1 , power plants and coal transportation systems, dry ash conveying pipe ;
2 , Stone Coal power plant systems ;
3 , the other a powder pneumatic conveying systems ;
4 , hydraulic transmission systems and larger particle size slag slurry transportation ;
5, other mining material handling .
