Uncompromising impact.
Hanjia designs and manufactures industrial nozzles: from descaling nozzles, flow stabilizers and headers to complete line layouts — every nozzle verified on our own impact-force test rig.
Jet
Every drop follows the same line
Velocity distribution, overlap and impact decide descaling performance — measured on every nozzle before shipment.
From one nozzle to a full line
Products
Descaling nozzles (Master / Energy-saving), Hanjia stabilizers, headers, TC-series flat-spray nozzles and accessories — matched to medium, pressure, flow and dimensions.
All products →Why it holds
Impact is measured, not assumed: a two-axis rig maps the whole pattern, and every nozzle is checked for impact, angle, jet thickness and flow.
Testing →Seven spray patterns
Testing & quality
Impact, measured.
Turbulence and splash-back make calculated impact unreliable. On our own test rig we measure impact distribution across the whole spray pattern in two axes — data used for selection, header design and batch verification.
- —Own two-axis impact test rig covering the full pattern
- —Per-nozzle checks: impact, spray angle, jet thickness, flow — all uniform
- —Cross- and length-wise impact distribution optimized from measured data
One nozzle, many goals

Applications
Tell us what to spray — we handle the selection
A nozzle is not a commodity: same flow, different medium, pressure or mounting distance and the impact and pattern change completely. We calculate until it works on your line.
- Medium
- Water / emulsion / cleaner
- Pressure
- 0.1 – 30 MPa
- Temperature
- 5 – 95 °C
- Connection
- 1/8" – 4"
High-pressure flat sprays strip scale — headers laid out by impact and overlap
→Secondary cooling zoned by water flux; air-water atomisation controls the rate
→Hollow-cone rings capture dust — low pressure, high flow, clog resistant
→Rotating heads cover the wall — impact class chosen by volume and residue
