Using bimetallic Metallurgical Grade Composite Technology.

Outer base pipe material: 20G seamless pipe.
Material of inner pipe: 304/316L seamless or welded pipe.
The problem of low interlaminar bonding force in common bimetallic composite pipe has been solved thoroughly.
Outer tube wall thickness is used as the bearing layer of the pipeline, to ensure the safety of pressure.
The wall thickness of the inner pipe acts as the functional layer of the pipe to make the base pipe more corrosion resistant.
 
Details:
1、Adhesion strength between layers is more than 210MPa, adhesion  rate is 100%
The combined force and heat transfer performance of the composite pipe are significantly higher than those of the existing composite pipe.
The interlaminar bonding force increased from 0.2 MPa to more than 210 MPa, 1050 times higher, and the bonding rate reached 100%.
2.200% of the thermal conductivity of pure stainless steel tubes
It is concluded that the thermal conductivity of stainless steel composite heat exchanger tubes is 150-200% of that of pure stainless steel tubes at different operating temperatures.
3.Its bearing pressure is no less than that of seamless steel tubes of the same specification.
Stainless steel composite heat exchanger pipes are suitable for industrial fields such as boilers, heat exchangers, pressure pipes and so on. It can really achieve the excellent effect of pressure bearing capacity of 1+1>2.
4.Excellent machinability tube
Stainless steel composite heat exchanger tube has excellent overall mechanical properties and mechanical properties. It can be used for various plastic processing and flexible connection methods such as welding, threaded connection and so on.
