Anti-corrosion induction heating equipment

1. Heating and spraying of anti-corrosion steel pipe

Anti-corrosion steel pipe heating spraying is divided into liquid epoxy anti-corrosion inside and outside the steel pipe and 3PE (PP)/FBE anti-corrosion steel pipe coating

1. The liquid epoxy anti-corrosion inside and outside the steel pipe of Songdao Technology Electric Furnace is:

a. After the intermediate frequency furnace heats the steel pipe, the spraying specification is φ508mm~φ3620mm

b. Implement SY/T0457, SY/T0447, AWWA C210 and other standards

c. Coating by airless spraying or centrifugal impeller coating machine

d. The core equipment of the liquid epoxy anti-corrosion production line inside and outside the steel pipe is: shot blasting machine for the inner and outer walls of the steel pipe, intermediate frequency heating furnace, automatic coating car, drying and holding room, etc.

e. The characteristics of the liquid epoxy anti-corrosion production line inside and outside the steel pipe are high degree of automation, stable operation and reliable coating quality. The intermediate frequency heating furnace has strong processing capacity and wide range. The anti-corrosion products are mainly used to transport oil, natural gas, water, coal slurry and other media.

2. 3PE(PP)/FBE anti-corrosion steel pipe heating coating production line of Songdao Technology Electric Furnace

a. 3PE(PP)/FBE anti-corrosion steel pipe heating coating and heating product specifications: φ219mm~φ2420mm

b. Implement SY/T0413, GB/T23257, DIN30670 and other standards

c. The core equipment of 3PE(PP)/FBE anti-corrosion steel pipe heating coating production line is: steel pipe inner and outer wall shot blasting machine, process transmission line, medium frequency induction heating system, epoxy powder electrostatic spraying system, polyethylene and adhesive extruder , pipe end grinding equipment, American Graco airless sprayer, curing room, etc. are all controlled by computer

e. 3PE(PP)/FBE anti-corrosion steel pipe heating coating features: advanced technology, production equipment with high degree of automation, stable operation, reliable quality, strong processing adaptability and other remarkable characteristics.

Second, the application scope of anti-corrosion steel pipe heating spray

The anti-corrosion steel pipe heating and spraying of Songdao Electric Furnace is mainly used to transport oil, natural gas, water, coal slurry and other media. It has the advantages of high adhesion, anti-oxidation, anti-moisture, anti-chemical corrosion and long service life.

3. Heating parameters of anti-corrosion steel pipe heating and spraying

1. Function: steel pipe preheating, powder curing.

2. The steel pipe is preheated to 320 degrees before powder coating, and the whole is preheated evenly. The end of the steel pipe is special-shaped and needs special heating. After being released from the oven, the temperature is naturally lowered to 280 degrees for powder coating and bonding.

3. Size The furnace is 2–8 m long and 1-3 m wide, and can pass through steel pipes with a length of 13.5 m and a diameter of less than 2500 mm. The wall thickness of the tube body is greater than 8mm.

4. The structure of the furnace body is horizontal, the steel pipe is suspended horizontally, and the chain travels in a step-by-step manner. The steel pipe rolls forward, and is preheated while traveling. Induction heating is adopted in an intermediate frequency furnace, and the temperature is reached in 2 minutes.

5. Other ends: centralized heating transmission: stepping + continuous conveying steel pipe operation adopts lateral steel shifting machine
