Nonstop pipe bundle conveyors
Bundle detangling machines
Dryer feeding machines
Tubes and pipes are fed into the line in bundles and directly hooked to the universal rack for their handling throughout the pretreatment process.
Bundles coming from the fluxing tank are placed on a sloping conveyor belt, sized to contain and receive multiple bundles simultaneously while preserving complete traceability. The bundles move toward the device that opens them, then aligns the individual tubes. These are then sent to the inlet of the dryer.
This equipment is fully automatic and requires occasional operator intervention.
Chain conveyor dryers
Our dryers ensure total drying and sensible preheating of tubes by allowing high immersion rates in molten zinc, avoiding burning of the flux and limiting heat shock deformation.
The drying performance is high thanks to the great amount of recirculating air flow passing around and through the pipes to be dried, without temperature set-point overshoot.
The drying air is heated up to the desired temperature by an indirect heat exchanger usually fed with steam.
Continous feeding for dipping machines
Dried pipes are picked up by a “walking beam” device which feeds the pipes launching rollways to have dipping line continuously fed.
This equipment is totally automatic and it requires a once in a while assistance by a controlling operator.
Dipping and extraction machines
This dipping machine is equipped with a double set of synchronized screws for dipping and extracting tubes in pairs; the innovative design allows for a decrease in kettle width while maximizing the number of tubes processed simultaneously.
The dipping screw sets can handle various tube sizes, with one set available for maintenance while the other is in operation.
The helical screw system ensures uniform zinc adhesion (managed by working recipes).
After dipping, the tubes are pulled out with vertical hooks. The machine can be easily disassembled for maintenance or improvement.
This equipment is fully automatic and requires occasional intervention by the operator.
Wiping and blowing withdrawing machines
Recovery and filtration of zinc oxides
This machine provides pipes to be cleaned of excess zinc after extraction from the kettle, both externally and internally.
The machine is suitable for small to large diameter pipes (in the case of larger diameters, the machine is equipped with a protruding blowing mandrel) and provides for the recovery and collecting the white fumes towards the plant filter.
This equipment is fully automatic and requires the occasional intervention of an operator.
Star-wheels for quenching tanks
Vapor collecting hoods
After dipping operations, pipes are released into a water quenching tank, featuring a star-shaped wheel element (easily removable from the tank for inspections and maintenance) that enhances operation efficiency by guiding and extracting the material from the bath. Vapors originated by quenching hot pipes are collected by a dedicated hood.
