Pipe Stress Analysis Services

Piping Stress Analysis Services

As a five-time Hexagon Elite award-winner, we offer comprehensive pipe stress analysis services to evaluate the structural integrity and flexibility of piping systems under various operational and environmental conditions. Our experienced team ensures that stress levels remain within permissible limits to prevent failures and meet global standards like ASME B31.3, B31.1, B31.8, and more.

Our pipe stress analysis expertise spans diverse industries and their applications, allowing us to identify potential stress issues early in the design phase and support in implementing effective mitigation strategies. We use industry-leading tools like CAESAR II, and more to deliver accurate, reliable results that support safe operations and long-term performance.

Our Pipe Stress Analysis Services

Rishabh Engineering team delivers end-to-end piping stress analysis services tailored to the specific requirements of our clients. From early conceptual design through to detailed engineering and construction support, we help EPCs, plant owners, and OEMs ensure piping system integrity and performance. We specialize in analyzing stress due to thermal expansion, internal/external pressure, seismic activity, wind loads, vibration, and other dynamic conditions. Our engineers conduct static & dynamic analysis and finite element analysis (FEA) while providing actionable recommendations such as routing modifications, selection of right support anchor location changes, and expansion loop designs to enhance system flexibility and code compliance.

Listed below are our focused pipe stress analysis services;

Thermal Expansion & Flexibility Analysis

Thermal Flexibility Assessment
Evaluate pipe stress and movement under thermal cycles.
Recommend expansion loops or supports to absorb displacement.
Ensure code compliance (ASME B31.1, B31.3) for temperature-induced loads.

Sustained & Occasional Load Analysis

Load Case Evaluation
Analyze piping for sustained loads like weight and internal pressure.
Evaluate occasional loads from wind, seismic, and equipment actions.
Identify critical stress points and support adjustments.

Vibration and Dynamic Load Analysis

Dynamic Stress Analysis
Assess mechanical, flow and acoustic induced vibrations.
Perform modal, harmonic, and time-history analysis.
Recommend solutions to mitigate fatigue and resonance failures.

Slug Flow & Water Hammer Assessment

Transient Force Analysis
Identify peak forces from sudden fluid momentum changes.
Evaluate effects of valve closures and two-phase flow surges.
Suggest pipe anchoring, routing and surge suppression strategies for stability.

Support and Hanger Design

Support System Design
Determine optimal support type and spacing for load control.
Design spring hangers, guides, and restraints to limit deflection.
Ensure system flexibility and load transfer balance.

FEA Nozzle Load Evaluation

Nozzle Load Verification
FEA for Nozzle, Trunnions, Special Pipe Supports, Miters, Bends and more
Analyze allowable loads on connected equipment nozzles.
Prevent overloading and misalignment issues on rotating/static equipment.
Coordinate with vendor data to ensure mechanical integrity.

Piping System Optimization

Piping Design Optimization
Streamline pipe routing to reduce stress and material cost.
Propose layout changes for better flexibility and accessibility.
Enhance system performance through cost-effective solutions.

Stress Isometric Generation & Reporting

Stress Report Generation
Generate detailed isometric drawings with stress annotations.
Document load cases, displacements, and restraint forces.
Provide clear code compliance summaries for client approval.

Failure Root Cause Analysis

Failure Cause Analysis
Investigate thermal, mechanical, or fatigue-related pipe failures.
Use reverse modeling and field data to diagnose root causes.
Recommend practical mitigation and repair strategies.

3D Model Integration & Clash Checks

3D Integration Review
Integrate stress analysis results with 3D plant models (Navisworks, PDMS, E3D).
Identify and resolve piping clashes and interference zones.
Facilitate multidisciplinary coordination and constructability reviews.
