Choose the heating tube of the right material and power

In the process of selling electric heating tubes, I often encounter customers who judge the quality of an electric heating tube is the length of time it is used. This standard was very important at that time, and a customer often mentioned that the quality of your heating rod is not good. , The power is too low and the temperature can’t rise, and customers often complain that the heating tube I bought on the Internet broke after a few days after it came back. Generally, except for the poor quality, most of it is the choice and use of stainless steel heating tubes. The environment does not match!
