Optional Components

Optional components include:

Turbo-Tunnel® System
Nelson Steel’s patented Turbo-Tunnel® design provides the most efficient turbulent pickling system. This unique system creates a high amount of turbulence around the strip, particularly at the strip edges where mill scale is the heaviest. The Turbo-Tunnel® design eliminates air space above the acid bath, thus reducing evaporation, heat loss, and acid consumption.

Wash System
The wash system is used to remove oil and other coatings from the strip prior to entering the pickling tanks, and to wash acid from the strip during a line reversal. This system can be installed as a single or double tank system.

Oil Separation and Alkali Recovery System
This system is provided to remove free and emulsified oil from the wash recirculation tank and return the clean water with alkali to the wash work tank.

Spill Line System
The purpose of the spill line system is to redirect any liquid that has gathered in the chemical pit sump to the most suitable location.

Water Treatment Systems
These systems condition the waste rinse water for disposal to a municipal sewage treatment plant by neutralization and precipitation of suspended solids. The design and integration of waste rinse water treatment includes clarifier and effluent-free systems. All water treatment systems incorporate the latest technology to ensure compliance with local regulation for effluent quality.

Boiler System
This complete steam generating system supplies sufficient steam for heating acid and water for all of the systems in the pickling line.

Feed Water System
This system preheats water from the softeners and chemicals from the chemical feed system before pumping them into the boiler.

Condensate System
This system is used to collect condensate from the heat exchangers and re-use it as feed to the boiler system.

Dry-Lube Coating System
This system provides the coating unit with various types of dry lubricant solutions.

Spray Rinse System
Prior to the development of our Stain-Free® design, the spray rinse provided sufficient water coverage over the strip to remove residual acid. This system is available if requested.

Structural Steel
This component consists of structural beams, columns, walkways, handrails, stairs, and platforms engineered and provided to support a complete pickling line.

Stack Tower
The stack tower is used to support the fume exhaust stack and comes complete with caged access ladders and inspection platforms at two elevations. The platforms allow access to the droplet eliminator and sample ports which are located on the stack.

Acid Proofing
Our acid proof lining system provides protective coverage throughout the processing section to resist corrosion from concentrated hydrochloric acid (HCl) and caustic.
