The quality standards of electric heating pipes are mainly based on several major indicators such as high pressure, working leakage, reliability life, and heating uniformity. Many product design engineers do not fully understand the knowledge of electric heating pipes and the real technology for electric heating pipes. The requirements and future performance are not very clear, so there are some misunderstandings about the standards of electric heating pipes. In addition, some well-known domestic companies have entered a long-standing misconception and brought high standards for electric heating pipes into the industry. Other companies blindly follow the requirements of large companies, so that many domestic manufacturers can The requirements of the tube are very high. For example, the insulation resistance should reach 1000 megabytes, the high pressure should reach 2000 volts, and the dry burning test, etc. must be done. It must be much higher than the UL standard and the IEC standard. The requirements for stainless steel electric heating tubes are much stricter than the international market. Strict requirements are correct, but excessively high standards do not mean that they are reasonable, because the higher the required standards, the need to use special designs, special processes, special materials to complete the production of heating pipes, the cost of materials It will be much higher. Therefore, some have no practical significance and high standards, but only increase the cost.
