ABOUT US
Hangzhou Fin Tube Co., Ltd. (HZFT for short), established on 2006, has grown into a leading international finned tube manufacturer in China. Over a decade, HZFT is committed to the developing, manufacturing and product extension of integrated finned tube. On 2017, it has been assessed as high-tech enterprise at State level.
HZFT has been devoted itself to shape the integrated finned tube since its foundation. We have self-developed two kinds of finned tubes based on different processes. One is extruded finned tube using on soft materials such as Copper, Cupronickel. The fins are obtained by roll forming the outer surface of a plain tube, which guarantees no heat resistance between fins and mother tube. a high heat transferring efficiency, a durable life and an amazing resistance to the...

Introduce the surface coating process of spiral plate heat exchanger
The spiral plate heat exchanger is a gas pressurizing component of the oxidizer tank in the whole engine system, which is used to provide the propellant supply pressure required for the normal operation of the engine. In the development process, the design requires that the inner and outer brazed and non brazed surfaces of the spiral plate heat exchanger be electroplated with Ni10~15 μ M, in which the coating on the brazing surface is required for subsequent welding with other components, and the coating on the non brazing surface is used as the high-temperature oxidation resistance protective coating during operation.

Understand the application of spiral plate heat exchanger spacing
Small cylinders or rectangles can be welded to the spiral plate heat exchanger. Its function is to maintain the distance between spiral plates and keep the distance between them consistent. It can greatly improve the rigidity, stability and strength of the spiral plate, and can also promote the flow of fluid and enhance its heat transfer effect. When most manufacturers use a fixed distance, it is caused by the concentricity of automobile manufacturing. Its center part will leave a residual bulge. In the volume of the spiral plate, the damage of the plate surface to the plate is very large, and the bearing capacity can be reduced. Semicircular simplified body. The blanking and shaping industry can effectively solve this problem.
