PRODUCT DESCRIPTION
1.Swirl preventers are widely used in chemical, energy, water engineering and other fields, especially in fire water pools (boxes),
2.Can ensure that the effective volume is fully utilized and improve the effective utilization rate of fire water pools.
3.Reduce dead water areas and achieve land saving requirements.
4.During rescue, fire water can be used to the maximum extent.
FEATURES
1.Flow optimization: reduce fluid resistance and energy loss.
2.Protect equipment: prevent vibration, wear or measurement errors caused by eddy currents in pumps, flow meters, valves, etc.
3.Versatility: suitable for liquids (water, oil, etc.) and gases (air, steam, etc.).
4.Maintenance-free design: no moving parts, simple structure and long service life.
5.Modular installation: adapt to a variety of pipe sizes (DN15~DN600) and connection methods.
APPLICATION
1.Pump inlet pipeline: prevent pump cavitation and extend pump life.
2.Flow meter upstream: eliminate fluid disturbance and ensure measurement accuracy.
3.Tank outlet/inlet: avoid liquid surface vortex causing gas mixing or incomplete emptying.
4.Cooling/heating system: reduce pipeline vibration and noise.
5.Chemical and energy: maintain stable flow in volatile or high-viscosity medium pipelines.
WORKING PRESSURE
Maximum working pressure 16 bar (230psi).
STANDARD
Product testing is carried out in accordance with GB/T13927 Industrial valve pressure test.
TEMPERATURE RANGE
0 °C to 80°C.
COATING
Fusion Bonded Epoxy Coating.
