Pipe Stress Water Hammer Analysis for Surge Protection and System Integrity

How JSC Engineers Helps Prevent Damage from Transient Hydraulic Surges

Pipe stress water hammer analysis is critical for liquid piping systems exposed to rapid changes in flow. Water hammer, or hydraulic shock, occurs when fluid velocity suddenly changes—causing high-pressure shockwaves that can rupture pipes, dislodge supports, or shut down your entire operation. At JSC Engineers, we deliver detailed transient modeling and mechanical stress analysis to help safeguard your system before problems arise.

What Causes Water Hammer?

Know the Risks Before They Cause Damage

Hydraulic surges are typically caused by:

  • Rapid valve closures or startups
  • Sudden pump trips or emergency shutdowns
  • Power failure in motor-driven systems
  • Filling or draining tanks, trucks, or marine vessels
  • Activation of NFPA 13 fire suppression systems

These events send pressure waves bouncing through the piping network, often far exceeding design pressures—especially at elbows, tees, reducers, and supports.

How We Perform Water Hammer Analysis

Hydraulic + Structural Modeling for Real-World Results

JSC Engineers combines transient fluid dynamics with structural pipe stress analysis. Our services include:

  • Unbalanced load calculation from time-varying flow events
  • Code-compliant stress evaluation per ASME B31.1, B31.3, and B31.12
  • Surge-induced fatigue life analysis and vibration review
  • Pipe anchor, guide, and support load evaluation
  • Dynamic simulation using AFT Impulse, CAESAR II, or Bentley HAMMER

When Should You Consider Water Hammer Modeling?

High-Energy Systems Deserve High-Level Engineering

  • New high-pressure or long-run liquid piping systems
  • Fiberglass/FRP systems per ISO 14692
  • Pipelines governed by CSA Z662 or ASME B31.4
  • Sprinkler/fire suppression system design and testing
  • Any system showing signs of surge, noise, or vibration
