What Factors Affect the Surface Quality of Stainless Steel Capillary Tubes?

Do you know what affects the quality of the surface of stainless steel capillary tubes? 304 stainless steel capillary tubes are seamless tubes that have good stretchability and corrosion resistance as well as a good appearance. The surface of the 304 stainless steel capillary tube is highly polished to a standard height. However, improper operation or inadequate preparation during the machining process can reduce the brightness of the 304 stainless steel capillary tube, so attention is needed.


Factors affecting the quality of stainless steel capillary tubes


An important factor that affects the surface quality of stainless steel capillary tube is the high oil content in the emulsion. The emulsion is an important solution for operation and processing of the stainless steel capillary tube in the cold rolling machine. It plays a crucial role in the smoothness and cooling of the stainless steel capillary tube, but the emulsion contains oil components. Petroleum at high temperatures will crack into carbon. If the oil in the emulsion is not cleaned up in a timely manner after high-temperature carbonization, it will accumulate on the surface of the 304 stainless steel capillary tube, and the rolling will form pressure marks. Due to the large amount of oil in the emulsion, after annealing the inner wall of the maintenance cover, carbonization accumulation will form on the inner wall of the maintenance cover. In other processing processes, this carbon black will be brought to the surface of the 304 stainless steel capillary tube, covering the surface of the 304 stainless steel capillary tube and affecting the appearance quality. After a long time of processing work, a lot of oil, carbon black and dust will also accumulate on the flow plate and furnace, and if not cleaned up in time, it will also fall on the surface of the stainless steel capillary tube. Keeping the surface of the stainless steel capillary tube clean can not only extend its service life but also save costs and create greater value for use.


Maintenance of stainless steel capillary tubes


Stainless steel capillary tubes are widely used in daily life, but maintenance may not be taken seriously. Proper maintenance and maintenance can prolong the service life of stainless steel capillary tubing. Here are some methods for maintaining stainless steel capillary tubes:


  • Wipe off the dust from the stainless steel capillary tube with a cloth every half month.

  • The processing accuracy of stainless steel capillary tubes determines its performance. Generally, the precision of seamless steel tubes is low, and the wall thickness is uneven, and the brightness of the inner and outer surfaces is low. It is difficult to remove the stain and black spot, which can be cleaned with water.

  • It is necessary to carry out offline treatment for testing and shaping of the stainless steel capillary tube. Therefore, it highlights its superiority in high-pressure, high-strength, and mechanical structuring uses. However, it cannot be wiped with alcohol.

  • The material of stainless steel capillary tubes undergoes elastic and plastic deformation under the effect of fluidity. If the stress is large enough, it will cause cracking. Pay attention to the interface when organizing.

  • Do not let the coil contact with acidic media, or the stainless steel will corrode.
