Over the years, and with an enhanced know-how following the acquisition of company CO.T.IMP.I, we at GIMECO have developed equipment for complete tubes and pipes hot-dip galvanizing lines that are highly reliable, aiming to optimize and standardize the production process at high-quality levels by controlling and managing its various phases.

We offer tubes and pipes galvanizing plant with a high level of automation. From the chemical pretreatment phase to the passivation phase, all operations are carried out entirely automatically with once in a while operator supervision. Great attention has been devoted to line management to preserve the surrounding working environment, complying with the strictest limits imposed by the relevant authorities.

The entire tubes and pipes hot-dip galvanizing line is designed to operate with high efficiency, achieving high productivity and quality performance. These, combined with comprehensive production control, have led to significant results in energy and raw material efficiency.

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.
