What are the classifications of electric heating tubes?

Electric heating tubes can be divided into the following categories according to the heating medium (heating object):

1. Air heating: Air heating can also be divided into exposed air dry burning and mold electric heating tubes

a. Types of air dry burning electric heating tubes

(1) Tubular air dry burning electric heating tubes: used in air dry burning environments such as ovens and drying rooms.

(2) Finned air dry burning electric heating tubes: heat sinks are installed on the surface of the heating tubes, which has a good thermal efficiency effect.

b. Mold electric heating tubes: holes are opened on the molds and plugged into dry burning electric heating tubes

2. Liquid heating:

a. Threaded single-head heating tubes: can be used on small oil tanks, automobile oil tanks, diesel engines and other small-volume containers.

b. Threaded threaded electric heating tubes: small water tanks, boilers and other containers with a power of less than 15KW.

c. Flat flange heating tubes: flat flange electric heating tubes used on larger equipment such as large boilers, hot water tanks, and thermal oil circuits.

d. U-shaped electric heating tube: U-shaped electric heating tube is used in frying pans, disinfection cabinets, rice steaming cabinets, etc.

The above is about the classification and application of electric heating tube types.

What are the components and types of electric heating tubes?

The electric heating tube is a tubular electric heating element that generates heat. According to the material, it can be divided into metal tubes, glass tubes, ceramic tubes, carbon fiber tubes, silicone tubes, etc. (Lilin Electric Heating only makes metal tubes)

The metal tubular electric heating element (heating tube) uses a metal tube as the outer shell (including stainless steel, copper tube, peptide tube), and spiral electric heating alloy wire (nickel-chromium, iron-chromium alloy) is evenly distributed along the central axis of the tube. The gap is filled with compacted magnesium oxide sand with good insulation and thermal conductivity. The two ends of the tube are sealed with silicone. The one with both ends sealed is called a double-headed tube, and the one with one end sealed is called a single-headed heating tube. This metal armored electric heating element can heat air, metal molds and various liquids.
