Market demand for stainless steel heat exchanger tubes is growing. The surface of the products we see in the market is relatively smooth. What specific requirements are required to process stainless steel tubes into qualified stainless steel heat exchanger tubes?
Here are the details from the material to the process:
1. Use grooved plastic pipe fittings as original.
2. The length of the connecting pipe segment shall be the net length between the two ports of the pipe segment minus the 6-8mm blanking material, with a gap of 3-4mm between each interface, and the number of stamps shall be used.
3. With mechanical cutting of the pipe, the section shall be perpendicular to the axis of the pipe. The allowable deviation range is:
A. When the pipe diameter is less than 100mm, the deviation is less than 1mm.
B. When the diameter is larger than 125mm, the deviation is not more than 1.5mm.
4. The wall of the outer wall of the wear-resistant steel-plastic composite pipe should be machined with 1/2 wall thickness fillet.
5. Use a special roller slot machine:
A. When the groove is pressed, the pipe section should be kept horizontal, and the steel pipe is 90° to the front of the groover.
B. When pressing the tank, it should be carried out slowly. The tank depth should meet the requirements.
C. The depth of the groove was measured with a standard gauge.
6. The outer end of the stainless steel heat exchanger tube that is in contact with the rubber seal ring should be smooth, and it cannot scratch the rubber ring or affect the sealed burr. Otherwise, the installation affects the installation and use of the heat exchanger.
The above six aspects are the relevant specifications and details in the process of machining stainless steel heat exchanger tubes.
