Safety and hygiene points in tubular heating elements design
Although the tubular heating elements is mostly used in industrial equipment, we should pay attention to the safety design. At the same time, the tubular heating elements can also be used in many food processing equipment. Therefore, the sanitary design is also very important. Next, we will introduce the design points of tubular heating elements under different working conditions
1. The electric tubular heating elements used for heating in combustible atmosphere should be designed to avoid explosion accident.
2. When designing the tubular heating elements used for heating pipe in pressure medium, the pressure relief accident caused by the damage of metal pipe, weld and seal should be considered.
3. The tubular heating elements 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 tubular heating elements in contact with food and eating utensils must comply with national health standards.
The above rules are taken from JB / T 2379-93 industrial heating pipe standard for reference only.
