The fixing of the outlet position of the heating tube directly affects the quality of the heating tube after use. Judging the qualification of a product does not mean that there is no problem after testing and use, it is intact. Our company Yancheng Songtai believes that the quality of heating tubes and other products is not only passed the test before use and passed to the customer for use, but also has a life time after use. Guaranteed, thereby strengthening strictness on every link in the production process.
Single-ended heating tubes are also called single-ended electric heating tubes. Compared with double-ended electric heating tubes, single-ended electric heating tubes are wired from one end and generally use star connection. Single-head electric heating tubes are generally used for mold heating or air dry burning, mainly for mold heating single-head electric heating tubes, which are directly inserted into the drilling holes of the mold, and the outlet ends are fixed with gaskets to prevent the electric heating tubes from moving.
Special attention should be paid to the matching of pipe diameter and template aperture when making single-head electric heating pipes. The pipe diameter of electric heating pipes is too large, causing the electric heating pipes to be unable to fit into the holes, and considering the expansion factor of the pipe after heating, it will bring about maintenance in the later stage. Inconvenience; in addition, it should be considered that the pipe diameter should not be too small, and the space between the hole wall and the hole wall should not be reserved too large, which will affect the heat transfer effect and service life of the electric heating tube. So when you order a single-head heating tube, you must pay attention to the diameter of the tube, and you must make it clear whether it is a positive tolerance or a negative tolerance before placing an order. I hope you can order the right product.
