We use advanced technology of hydraulic expansion method to connect tube and baffle. This process, to a great extent, reduces the surface damage caused by the cylinder expansion, such as hardening work and thinning of the tube in the expansion. ln addition, all of our overall two-way thin tube actually reduces pressure between tube and baffle interface in order to maintain consistency, reduce maintenance time and lengthen the service life of the equipment. Before shipment, each heat exchanger should be tested with strict test and program file.
●Fluid static test.
●Fuel penetration test.
●X ray analysis.
Surface photometer to ensure that the surface roughness of mechanical and electrolytic polishing Ra below 0.25 u m.
●Computer verification performance
●Detection of light and endoscopy.
