Revitalising BlueScope Steel’s 40-Year-Old Wash Tunnels

cost-efficient, descaling, safer alternatives

Achieving more than 90% Recovery with Envirofluid’s Triple7 Enviroscale

At first glance…

BlueScope Steel’s facility in Hastings, Victoria, has been a cornerstone of the steel manufacturing industry for over 40 years. However, with equipment of this calibre, we are faced with a unique set of challenges.

With the age of the machine and decades of scale buildup, there’s an amount of risk with any descaling treatment, that may damage equipment, operation and efficiency.

Here’s the story…

BlueScope Steel’s wash tunnel facility in Hastings has been in operation for around 40 years, primarily used for washing and etching coiled steel before colour coating. The system relies on potable water, dosed with chemicals for use and recirculation. However, decades of operation had led to substantial scale buildup, severely inhibiting the wash tunnel’s effectiveness.

The challenge was clear—how to restore the facility’s efficiency without enormous downtime or excessive costs.

The washing tunnel’s inefficiency was costing us time and money, and the maintenance was becoming unmanageable.
