Description

1. Main parameters of steel pipe coating production line

No	Item	Specification
1	material	steel pipe
2	pipe length	6-18m
3	pipe diameter	57-3048mm
4	coating type	liquid coating

2. Technological process of rack electroplating
Loading → preheating → external shot blasting for rust removal → internal shot blasting for rust removal → internal spraying → external spraying → curing → leak detection → unloading

3. Main process introduction
Preheating:
Drying the steel pipes ensure will not be affected by rain, snow, frost, dew, etc.

External shot blasting for rust removal:
The interior wall protection board of the external rust removal machine is made of rolled manganese 13 alloy plate, which is welded and formed once, and the wear resistance time reaches 2000 hours.
The cleaning room of the external rust removal machine adopts a main chamber and side auxiliary chamber structure, with less splashing.
The external rust remover is equipped with a movable transparent protective plate on the outdoor side for safer operation and more convenient movement during maintenance.

Internal shot blasting for rust removal:
The interior wall protection board of the internal rust removal machine is made of rolled manganese 13 alloy plate, which is welded and formed once, and the wear resistance time reaches 2000 hours.
The cleaning room of the internal rust removal machine adopts a main chamber and side auxiliary chamber structure, with less splashing.
The internal rust removal machine adopts a 3-turntable layout, and the turntables on both sides can be adjusted according to the pipe length to better adapt to steel pipes with a length of 6-18m.
The internal rust removal machine is an integrated rust removal and blowing machine.

Internal spraying:
The internal spraying machine transmission and exhaust gas treatment system motors are all explosion-proof motors. To adapt to the spraying environment of more types of coatings.
The internal spraying units are arranged with 3 turntables, and the turntables on both sides can be adjusted according to the pipe length to better adapt to 6-18m steel pipes.
The exhaust gas treatment system of the internal spraying units adopts precise segmented air induction technology, which saves more electricity.

External spraying:
The external spraying machine transmission and exhaust gas treatment system motors are all explosion-proof motors. To adapt to the spraying environment of more types of coatings.
The external spraying units are arranged with 3 turntables, and the turntables on both sides can be adjusted according to the pipe length to better adapt to 6-18m steel pipes.
The exhaust gas treatment system of the external spraying units adopts precise segmented air induction technology, which saves more electricity.

Curing:
The coating changes from liquid to solid.

Leak detection:
Detect the coating for leakage points.
