Steel pipe FBE/3PE/PP coating equipment
Steel pipe FBE, 3PE(PP) external anticorrosion production equipment are designed for the anticorrosion coating of oil, natural gas, chemical material, water pipelines. The equipment are capable 1-layer & 2-layer FBE, 2-layer & 3-layer PE (PP) coating. Its anticorrosion techniques and product performance are in full compliance with DIN30670-91, Q/SY/TQ9-2003, SY/T0413-2002 and SY/T0315-97.
Equipment description
Steel pipe washing equipment
Water washing system
It is used to wash pipe surface with high pressure water and improve the blasting effect. It can wash away dust and impurities.
Acid washing water washing system
Through chemical treatment, this system can help remove impurities on steel pipe surface and phosphorize and passive steel pipe surface to improve the effectiveness of steel pipe surface treatment and coating adhesion.
Steel pipe heating equipment
Steel pipe heating equipment is used to heat pipes. It can preheat, heat and curing pipes with different technological requirements.
Steel pipe preheating equipment
It is used to heat the pipe from 40℃ to 60℃ before blasting, and to wipe off water, moisture and greasy dirt on the surface, which can meet the demands of rust removal.
It includes intermediate burner heating and frequency heating (see intermediate frequency heating) form. The heating media of burner can be gas and diesel
Steel pipe heating equipment
Intermediate frequency heating system is mainly used to heat pipes to 180℃- 230℃ to meet the coating standard.
Steel pipe blow equipment
The internal blowing system is used to clean the dust, and sand inside the pipes by the draught fan, so that it can prevent the pollution when coating.
The system includes pipe internal blowing carrier, dust collecting box, pulse back-blowing dust collector, live rotation roller, pipe stopper, etc. A set of filter-barrel type pulse back blowing dust collector is equipped on the dust collection box.
Dust treatment
It is used to clean dust and abrasive on pipe surface after blasting and improve the adhesion of FBE.
Epoxy powder coating equipment and recovery system
The system includes stainless coating room, epoxy powder guns, powder coating controller, fluidization powder box, dual cyclone collecting structure, and pulse-blowback-cylinder dust catcher.
Extrusion system
It is used to extrude PE adhesive and PE protective coating, which are twined to the external wall of the pipes. The polyethylene protective coating can protect the epoxy powder coating.
It can be divided into cladding type and twining type according to coating pattern and twining type can be divided into side type and upper type.
The cladding type
Two sets of extruder are placed on live platform which can drive die go up and down. There are two guide rails which can help adjust the distance between die and pipes. Two sets of dies can move up and down according to different needs. Pipes can go directly through the die and AD & PE can wrap on the pipes uniformly.This can not only help save material, but also prevent roller from wearing.
However, since the coating line is running in linear way, the homogeneity of the powder coating may be affected, so this device is only suitable for the pipes with diameters under 630.
Side type
In this type, die is side blew pipes and the adhesive and polyethylene press rollers are directly blew pipes. The AD extruder and PE extruder are placed vertically with production line. They can move back and forward (AD extruder can move laterally) to adjust the angle between coating layer and steel pipes.
Upper type
Two sets of extruder are placed on one side of production line. The extruder is vertical to production line. The extruders are placed on live platform and die and extruder can move up and down. Pressing roller and guide roller are separately placed on a live scaffold. This can help easily adjusting the extrusion and wrapping equipment according to different pipes and also adjusting the width of coating layer. It can not only ensure the uniformity of PE, but also save raw material.
Since the space under pipes is unlimited, pipe carrier can be installed under pipes. As a result, there is no need to use pipe connecting device. In the meanwhile, the cutting of rudder at the end of pipes can be achieved.
Co-extrusion
This type of extrusion develops on the basis of consumer’s different needs. One set of extruder can be installed flexibly and wrap in many ways, in addition, the cost is low. Co-extrusion type is really suitable for coating pipes with different diameters. Consumer can choose one extruder or two according to different production requirement. It can greatly save production cost, but its price is a little bit high.
Steel pipe water spraying equipment
The water cooling system is used to cool heated piped rapidly to the temperature of 40℃-60℃, to protect its anticorrosion layer and protection layer.
Water cooling system consists of water cooling room, water cooling tower, self-prime pump, centrifugal pump, pipeline, etc. There is a back water pond near cooling room.
Cutback machine
This device is used to remove pipe-end coating layer and then form a groove whose angle is below 30°, in order to joint easily.
It is double-head high-efficient cutback machine. It is composed of steel brush, polishing motor, moving trolley, high efficiency dust collector etc. It is also equipped with lifting rotation roller, rocker arm etc.
