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.

Backpack wear resistance ceramic elbow with flange

Six performance summary of the composite pipe of the ceramic composite pipe 1, good wear resistance Ceramic composite pipe with inner liner for ceramic corundum (a-AL2 (subscript) O3 (subscript, similarly hereinafter), Mohs hardness can reach 9.0 rather than hrc90. Therefore, the grinding medium of all industries are highly resistant to wear. The industrial operation confirmed: its wear life is ten times the quenching steel or even dozens of times. 2, running resistance: Ceramic composite pipe due to the smooth surface of the inner surface is better than any metal pipe, water resistance coefficient of 0.0193, slightly lower than the seamless tube. 3, corrosion resistance, anti fouling: Since the ceramic layer is (a-AL2O3), it is a neutral material. Therefore has the acid alkali and water resistance, and at the same time with anti - scale and so on. 4, heat resistance and heat shock resistance performance is good: As the corundum ceramic (a-AL2 (subscript) O3 (subscript)) is a single st

Sleeve Type Expansion Joints

Sleeve Type Expansion Joints are primarily designed to compensate for thermal expansion but it is not the only movement being imposed on the pipeline system. Other types of movements can occur that need to be taken into account when providing a pipework flexibility solution such as building settlement, wind loading, vibration from rotating and reciprocating machinery. Related Ceramic lined pipe Ceramic lined pipe is made through self-propagating high-temperature synthesis (SHS) technique.
