PIPING STRESS ANALYSIS

We are specialized consultants for all critical systems; we performed piping flexibility static and dynamic stress analysis of following systems with given codes and standards.

Thermal and Sustained Stress Analysis of high and cryogenic temperature piping and large diameter piping (ASME B31.1, ASME B31.3, ASME B31.4, ASME B31.8, CSA Z662).

Evaluation of loads on various types of equipment such as:

• Centrifugal and Reciprocating Compressors (API 617 and API 618)
• Steam Turbines (NEMA SM 23)
• Centrifugal and Reciprocating -Pumps (API 610 and API 674)
• Shell and Tube and Plate Exchangers (API 662 and HEI Standard)
• Towers and Horizontal Pressure Vessels
• Fired Heaters (API 560)
• Aerial Coolers (API 661)

Scope Of Work For Pipe Stress Analysis

• Static & dynamic thermal stress analysis for given load cases. .
• Analysis for occasional conditions like wind loads, pressure relief loads due to safety valve operation.
• Analysis and submission of stress report as per  Caesar II version 2018.
• Code compliance & nozzle evaluation as per stress philosophy & equipment details/ allowable loads provided.
• Stress analysis & Pipe support tagging for modified line.
• Preparation of Stress report & spring hanger data sheet for defined lines.
• Structure loading.
• Seismic analysis as per response spectrum method as per site Spectra.
• Dynamic loads due to pulsating flow / two phase flow with slug flow with min acceptable  frequency for transfer line.
• HC lines to be analysed for Steam out condition as per process requirement.

Scope of work for Pipe supporting

• Primary support tagging/ back checking of all IFC isometrics .
• Preparation of spring hanger data sheet
