During hydromechanical descaling, cooling, breaking and evaporation effects interact and reinforce each other. The scale layer is broken up by the high-pressure water jet, the scale shrinks due to spontaneous cooling, the abruptly evaporating water acts like countless small explosions and blasts off the scale, which is then rinsed off by the remaining water. Compared to mechanical processing, descaling with water is by far the more effective and economical process.

• Billet and bar mills
• Section and ring rolling mills
• Forging descaling lines
• Thin slab and casting rolling mills

HP²compact is the synonym for multiple function and high-performance at a minimum of space. The valve housing, made of highgrade, forged stainless steel includes all interconnecting holes and thus contains the entire logic itself. Due to the significantly minimized number of flange connections, leaking flange points and the associated production down-times are a matter of the past.

Especially in new plant construction, the greatest advantage is obvious: The enormously reduced space requirement compared to
the conventional single valve arrangement significantly reduces the required infrastructure and thus the investment costs.
