What do you think are the specific requirements for the processing of stainless steel heat exchange tubes?
The details of stainless steel heat exchange tubes from raw materials to processing are mainly introduced as follows:
1) Select grooved plastic-coated pipe fittings as the original.
2) The length of the connecting pipe section should be the net length between the two mouths of the pipe section minus 6-8mm material, and there should be a gap of 3-4mm between each joint, and stamped with a serial number.
3) When cutting the pipe by machine, the section should be perpendicular to the axis of the pipe, and the allowable deviation range standard is:
① When the pipe diameter is less than or equal to 100mm, the deviation is less than or equal to 1mm
② When pipe diameter > 125mm, deviation ≤ 1.5mm
4) The end face of the outer wall of the wear-resistant steel-plastic composite pipe is rounded with 1/2 wall thickness by machining.
5) Use a special rolling grooving machine to press the groove:
① When grooving, the pipe section should be kept horizontal, and the steel pipe and the front of the grooving machine should be at 90°.
②The process of grooving should be carried out slowly, and the groove depth should meet the requirements.
③Use a standard gauge to measure the depth of the entire circumference of the groove.
6) The outer end of the stainless steel heat exchange tube that is in contact with the rubber sealing ring should be flat and smooth, and the rubber ring should not be scratched or have burrs that affect the seal, which is related to the installation and use of the stainless steel heat exchange tube.
These are the processing requirements and details of stainless steel heat exchange tubes.
