3WASHING

WASHING
Function

This device removes foreign substances from the pipe surface by washing the pipes with high-pressure water. It then dries the moisture with air before the intermediate frequency induced preheating stage.

- High-pressure pump and nozzle – 5 k ∼ 7 k(Hydrostatic pressure)
  : 1 set

- Air knife – 5 kg/cm2 (Compressed air): 2 set

- Water tank and heater(3 kw – 2 ea.): 1 set

4INTERMEDIATE FREQUENCY PRE HEATER

INTERMEDIATE  FREQUENCY  PRE HEATER
Function

This device preheats the pipes before painting.

Specification

- Type: Intermediate frequency induced heating

- Capacity: 450 kw

- Heating temperature: Max.150

- Heating method: Induced heating by material feeding with
  single-phase coil

- Heating rate: 20〜80 MPM

- Cooling capacity: 150 L/min.

- Hydraulic pressure: 3 ∼ 4 kg/cm2

5PAINTING BOOTH

PAINTING BOOTH

5-1. Painting booth_Spray booth

Function

This device paints the surface of the square pipes, which have been preheated to about 90 degrees at the intermediate frequency induced pre-heater, by spraying water-soluble paint through the spray nozzle.

Specification

- Size: W2,000 x H1,800 x 2,000 L

- Type: Spray type

- Q'ty: 1 set

Painting spray system_Spray unit
