What are the difference between the tube and the infrared heating quartz tube both

Difference between the tube and the infrared heating quartz tube both are: general electric wire electric heating, the heating wire red state heating, heat by radiation, but there are also some infrared radiation, and when coupled with emulsion quartz tube, increase the amount of infrared radiation, high heating efficiency. And used for making heating tube quartz tube must be special quartz tube (white), also called infrared heating pipe.
