Water Jet Descaling System | 150 - 180 HP

Severe-Duty Hydro-Mechanical Descaling for Extreme Scale Conditions PressureJet 300–400 bar high-pressure descaling systems are engineered for severe oxide scale removal applications, where conventional descaling pressures are insufficient to achieve the required surface cleanliness. These systems are designed for primary descaling in high-temperature rolling mills, handling thick, tightly bonded oxide layers formed during prolonged reheating and processing of stainless steel, special alloy steel, bearing steel, tool steel, and high-grade carbon steels. Operating at ultra-high hydraulic pressure, PressureJet descaling systems generate exceptionally high jet impact energy, enabling deep penetration and effective removal of stubborn scale without mechanical intervention. These systems are ideal for primary descaling zones immediately after furnace discharge, where scale thickness and adhesion are at their maximum. Built around ultra-heavy-duty reciprocating plunger pump technology, PressureJet 300–400 bar descaling systems deliver stable pressure output, controlled flow, and repeatable jet performance, even under continuous severe-duty industrial operation. Technical Description The descaling system operates using an ultra-heavy-duty positive displacement plunger pump, configured in triplex or quintuplex arrangement, specifically designed to withstand extreme pressure cycles and high dynamic loads. Unlike centrifugal or medium-pressure systems, PressureJet’s high-pressure plunger pumps maintain constant hydraulic energy and sustained jet momentum, which is essential for breaking dense, high-temperature oxide scale formed on specialty steels. Hydraulic energy is converted into ultra-high-velocity flat-jet water streams through heavy-wall descaling headers and erosion-resistant nozzles, delivering concentrated impact force at the steel surface. The optimized spray geometry ensures uniform descaling coverage, controlled water usage, and consistent performance across varying billet sizes and rolling speeds. This design enables: • Aggressive fracture and removal of thick, adherent oxide scale • Effective descaling at extreme steel temperatures • Controlled material removal without base metal damage • Reduced dependence on mechanical cleaning or grinding • High descaling efficiency under severe metallurgical conditions Key Applications • Primary descaling of billets, blooms, and slabs immediately after furnace exit • Stainless steel and special alloy steel rolling mills • Bearing steel, tool steel, and high-grade alloy steel processing lines • Heavy section and high-temperature rolling mills • Severe scale removal applications where lower pressures are ineffective Engineering Highlights • Operating pressure range: Up to 300–400 bar • Pump type: Ultra-heavy-duty reciprocating plunger pumps • Pump configuration: Triplex with reinforced crankcase • Crankshaft design: Oversized forged crankshaft with high-load bearing arrangement • Plunger material: Advanced solid ceramic for extreme wear resistance • Construction: Reinforced skid-mounted system with structural base frame • Filtration: High-capacity multi-stage filtration with redundancy for nozzle protection • Hydraulics: Low-pulsation design for stable jet impact under extreme pressure Advantages for Severe-Duty Descaling Applications • Maximum descaling efficiency for thick and adherent oxide layers • Superior surface cleanliness for high-value steel products • Reduced roll wear and surface defects, improving downstream process stability • Extended equipment life in extreme operating environments • Reliable continuous operation under high pressure and thermal stress Ideal Descaling Solution for Extreme Operating Conditions The 300–400 bar PressureJet descaling system is the preferred solution for steel producers requiring maximum descaling performance, where surface quality, metallurgical integrity, and productivity are non-negotiable.
