Water Hammer(also Known As Water Hammer) Is A Phenomenon Of Sudden And Violent Pressure Fluctuations In Pipeline Systems Caused By Rapid Changes In Water Flow Velocity. It Is Often Caused By Sudden Opening And Closing Of Valves, Start And Stop Of Water Pumps, Etc., Which Can Cause Strong Impact On Pipelines And Connecting Parts. As A Commonly Used Rigid Connection Method In Pipeline Systems, Flange Connection Is The Core Point Of Adapting To Water Hammer Protection, Which Is To Ensure Connection Sealing And Structural Strength, And Resist Instantaneous Impact.

Water Hammer Is Divided Into Positive Water Hammer And Negative Water Hammer. Positive Water Hammer Can Cause A Sudden Increase In Pressure Due To The Obstruction Of Water Flow, Which Can Easily Lead To Flange Sealing Failure, Bolt Loosening, And Even Pipeline Cracking; Negative Water Hammer, Due To The Formation Of Vacuum Inside The Pipeline, May Cause Damage To The Inlet And Sealing Surfaces Of The Flange Interface. The Installation Accuracy And Sealing Quality Of The Flange Connection Directly Determine The Safety Of The Pipeline System Under Water Hammer Impact, Which Needs To Be Carefully Controlled.

The Flange Connection Connects Pipelines Through Components Such As Flanges, Bolts, And Sealing Gaskets, And Has The Characteristics Of Firm Connection, Reliable Sealing, And Adaptability To High-pressure Working Conditions. It Is Widely Used In Various Industrial And Municipal Pipelines. When Dealing With Water Hammer, It Is Necessary To Use Flanges And Bolts That Match The Pressure Rating Of The Pipeline. The Sealing Gasket Should Be Made Of Impact Resistant And High-pressure Resistant Materials To Ensure That The Bolts Are Tightened Evenly And Avoid Uneven Local Stress That May Cause Impact Leakage.

At The Same Time, Flange Connected Pipelines Need To Be Equipped With Water Hammer Protection Equipment, Such As Installing Slow Closing Check Valves And Water Hammer Eliminators At The Pump Outlet To Slow Down Sudden Changes In Water Flow Velocity And Absorb Impact Energy; Avoid Frequent Starting And Stopping Of Water Pumps And Sudden Opening And Closing Of Valves To Reduce Water Hammer From The Source. It Is Suitable For High-voltage Pipeline Systems Such As Drainage, Chemical, And Power Systems. After Taking Protective Measures, It Can Effectively Resist Water Hammer Impact And Ensure Stable Operation Of The Pipeline System.
