Production process and characteristics of boiler flange electric heating tubes

Production process and characteristics of boiler flange electric heating tubes

The majority of flange heating tubes are made using argon arc welding to connect the heating tube to the flange for centralized heating, or by using a fastening device, where each heating tube is welded with fasteners. Then use nuts to lock the flange cover. The pipes and fasteners are welded using argon arc welding, ensuring no leakage. The sealing of fasteners adopts scientific technology.

Characteristics of boiler flange electric heating pipes:

1. Small size and high heating power.

2. It can heat various media in various occasions, such as explosion-proof situations.

3. The heating temperature can usually reach 700 ℃.

4. The heating system can be fully automated and controlled, including the operation of the electric heating system through the DCS system.

5. It has a long service life, multiple protection systems, and is safe and reliable.

Advantages of stainless steel boiler flange electric heating pipes:

The flange electric heating tube is composed of multiple heating tubes welded onto the flange for centralized heating. Mainly used for heating in open and closed solution tanks and circulation systems. It has the following advantages:

1. It has good thermal efficiency and uniform heating.

2. High temperature and corrosion resistance.

3. It has good safety performance.

4. The surface power is high, which increases the surface load of air heating by 2-4 times.

5. The flange electric heating tube uses high-quality thick walled seamless stainless steel tubes, high-temperature magnesium oxide powder imported from the United States, and sealing materials, which can withstand temperatures up to 900 ℃ and will not be damaged during dry burning under temporary dehydration.

6. Adopting an atmosphere protected blackened mesh belt furnace and undergoing high-temperature nitriding treatment at 1060 ℃, the high temperature and corrosion resistance of the electric heating tube are improved, ensuring its service life.

7. The sealing of fasteners adopts scientific technology, making single replacement extremely convenient and greatly saving future maintenance costs.

8. The flange electric heating tube is highly dense and compact in structure. Due to its short and dense overall length, it has good stability and does not require a bracket for installation.

9. Choose high-quality imported and domestic materials, adopt scientific production processes, and implement strict quality management to ensure the high-quality electric heating performance of the electric heating tube.

10. Long service life: The main technical indicators are in accordance with JB/T2379-93 "Metal Tubular Electric Heating Elements" and JB/T 4088-99 "Daily Tubular Electric Heating Elements", and the product service life is ≥ 4000h. The product is suitable for various industrial electric boilers.
