Online Zinc Spray Coating System For Tube Mill

The Cylinder is placed manually on a twin roller conveyor which moves forward in the longitudinal direction as well as rotates inside the dry spray booth. The twin roller conveyor is driven by an electric motor. The Operator spray Zinc with the help of either a Wire Flame Spray Gun or Arc Spray Gun (Air Drive or DC Drive) with a Power Source.

The dust and fume created during the Zinc metalizing process are sucked by the exhaust fan mounted on Fabric Dust Collector. The Cyclone collect the coarse dust and very fine dust get collected in the Fabric Bag Dust Collector, keeping the environment clean and friendly

G. I. Tubes and pipes delivered from Tube Mills generally need corrosion resistance property at weld portion, throughout the entire crease length (because of removal of the galvanized layer while welding the crease) resulting in helpless corrosion resistance and ensuing rusting. Micro Blaster has analyzed the issue and grown chemically non-risky thermal spray systems for continuous online zinc spray coating on G. I. Tubes and Pipes on the crease.

Such systems have been shown and supplied to various leading tube mills where these systems have been performing satisfactorily. The Zinc spray is 20 to 30 Microns. Nonetheless, 10 to 100 microns can be deposited (depending upon tube/pipe cross speed) on Tubes and Pipes ranging from 15mm N.B. to 125mm N.B. Size without interrupting Tube Mill speed. The average yield can be 10 pipes each minute with an approximate 25 microns coating thickness. The System package consists of a dry spray booth (Spray Chamber), Twin Cyclone, Exhaust Fan with engine along ducting.

The Spray Booth is installed soon after welding Work Station. The Arc Spray Gun is positioned inside the Spray Booth. The distance of the spray gun from the tube/pipe is changed depending upon the size of the tube/pipe and the spray design required to minimize spray wire misfortunes. The Hot Weld crease is sprayed with zinc wire resulting in a thick coating with a strong metallurgical bond over the weld crease.

The vapor and fine Zinc dust generated in the spray booth are sucked into the cyclone dust collector because of suction made by the exhaust fan. Because of cyclonic action, the zinc particles are caught at the lower part of the cyclone dust authority, and clean air is discharged from the power source of the blower into the climate keeping.

The Arc Spray Gun System consists and of Arc Spray Gun with a two-wire feeding arrangement DC/AC Power source built-in with control console with wire spool stand having spool capacity 15Kgs each. The Wire feeding mechanism is by pull measure controlled by an electric engine. The wire feeding speed is customizable through the engine. The zinc spraying is a cool cycle producing fine and thick quality coating having high bonding strength and minimum porosity.

Any metal sprayed deposit exhibits some degree of porosity (henceforth the need to apply slightly thicker sprayed deposits than the pre-coatings which are hot-dip. The 'as sprayed' deposit has a fine satin appearance, surface finish. In the wake of spraying, the sizing move stations of the tube mill will slightly deform the sprayed deposit to create a smoothed partially shiny appearance. The sizing operation will also diminish surface porosity. The sprayed coating will withstand deformation and manipulation.

For Zinc Metallizing of the external surface of LPG Cylinders Minimum diameter 305mm x 620mm length & maximum diameter 350mm x 730mm length Production Output:
700 to 800 nos. per shift cylinder diameter 305mm x 620mm length with Arc Spray Gun.

Micro Blaster offers a complete zinc spray coating plant for tube mill application. ERW tubes after welding lose their anti-corrosion property where welding is done on the seam. We offer a twin wire arc spray coating system with a complete fabrication unit. We are also the supplier and exporter of Sand blasting machine, Grit Blasting machine, and abrasive media at a low price for sale in Rajasthan, India.
