Safety and hygiene design of electric tubular heater:
Although electric tubular heaters are mostly used in industrial equipment, we should pay attention to the safety design. Colleagues, electric heating pipes will also be used in many food processing equipment, so health design is also very important. Next, we will introduce the design points of electric heating pipes under different working environments
1. The electric tubular heaters used for heating in combustible atmosphere should be designed to avoid explosion accident.
2. The electric tubular heaters used for heating pipe in pressure medium should be designed to avoid pressure relief accident caused by damage of metal pipe, weld and seal.
3. The electric tubular heaters used for heating in toxic and harmful medium should be designed to avoid leakage accident caused by damage of metal pipe, weld and seal.
4. The shell or coating of electric tubular heaters in contact with food and eating utensils must meet the national health standards.
The above rules are taken from JB / T 2379-93 industrial heating pipe standard for reference only.
