From now on, in order to strengthen exchanges among sea friends, we have launched a [Daily Question] activity in the Animal Equipment Technology Edition. We hope that everyone will actively participate and make progress and improve together! ! ! award: Actively participate in 3 fortunes and answer 10-15 fortunes intact. This question is valid for two days and will not be graded for more than two days. question: As shown in the picture, the necessary tools for refrigeration are mostly used for air conditioners and rarely used for refrigeration. Please name them and their functions. Answer: Pipe expander suitable for both metric and imperial systems 1. Pipe expander suitable for both metric and imperial systems, the expansion size is (imperial): 1/4'' 5/16'' 3/8'' 1/2'' 5/8'' 3/4'', (metric) is 6, 8, 10, 12, 14, 16, 19mm. 2. Expanding the pipe in a rotating manner not only saves labor, but also can expand the pipe quickly. The expansion arc can accurately present a 45-degree bell mouth. 3. The spring seat design is included so that after the pipe is expanded to 45 degrees, the spring will automatically spring open, causing idling, without scratching the pipe, and making the bell mouth of the expanded pipe smoother and more beautiful. 4. The arrow indicator can be accurately aligned with the axis, making the tube expansion roundness more accurate. 5. The high-hardness eccentric shaft is titanium-plated, which can expand the pipe for a long time, and it is easy to clean the burrs caused by long-term pipe expansion, and it is not easy to cause wear and scratches on the pipe after repeated use. ================================ Event promotion: Petrochemical Zone---"Brain-expanding" activity on new energy-saving ideas (the second phase of the activity is in progress) http://bbs.hcbbs.com/thread-1666758-1-1.html (Source: Haichuan Chemical Forum Network) "My Technical Transformation of Coal Chemical Industry in 2017"” http://bbs.hcbbs.com/thread-1786290-1-1.html (Source: Haichuan Chemical Forum Network)
