Engineering Analysis Services

Pipe stress analysis services:

With Its expertise in piping systems, ImageGrafix offers Pipe Stress Analysis Services and Pipe Support Engineering to its clients. This service caters to the requirements of both Process Power, and District Cooling Piping Systems

Pipe Stress Analysis

Pipe Flexibility is a critical component in any piping design. It is mandatory that the critical piping which are operating under high pressure or high temperature services need to be analyzed for flexibility , expansion and load sustaining capabilities. Apart from process and power piping, District cooling systems which employ pre-insulated pipes and piping inside the energy transfer stations need to be analyzed for flexibility and expansion as per ASME B31.3 code. ImageGrafix offers comprehensive service which covers all aspects of Pipe Stress analysis in both industries.

Pipe Stress Analysis for District cooling Piping and Energy Transfer Station Room Piping

The purpose of the stress analysis in Chilled water Network lines is to identify the behavior of the Chilled water pipes under the potential static loadings experienced from the start up to operation. In particular, the stress analysis is undertaken to confirm that stresses produced in the network as a result of the temperature difference, pressure and dead weight will comply with the governing codes for such static loads. Moreover, the calculated displacements and restraint (anchors and hangers) loads under these static conditions should comply as well with these governing codes.
Due to the extensive calculations required, the stress analysis will becarried out with the assistance of computer simulation and modeling software.
The stress analysis provides useful design information including the location of any high stress concentrations and bends within the network it also highlights areas requiring attention by way of redesign and or adding additional anchors or hangers to eliminate high stresses in the network piping.

Root Cause analysis

IGES team can visit the site and collect necessary information and accordingly analyze the problem analytically considering design aspects (Critical, Logical, Stress Analysis, etc) and provide recommendations for any piping modifications so as to overcome the prevailing piping related problems.

Typical problems may be:

  • Compressed Air Flow Analysis: Inadequate flow of plant air, instrument Air to the user points.
  • Water Flow Analysis: Inadequate flow of cooling water, Service water, potable water, etc to the user points.
  • HVAC Calculations: Inadequate suction of toxic fumes from originating points
  • Expansion Joint failure: due to improper pipe support design.
  • Pipe Support/ Spring Support failure.
  • Excessive Vibration: Suspected to be due to rigid or poor piping design.
  • Piping Flange Joint leakage: This may be due to improper Pipe support design.

Fluid Flow Dynamics Services

ImageGrafix can offer advice in designing the hydraulic system to be more optimized to its purpose, to improve its safety and to cost less money. Typically the services include:

  • Determining the maximum flow capacity of a system (e.g. ship/ shore cargo transfer).
  • Advising on pipeline routing and elevation profile.
  • Optimizing the pipe diameter by calculating flow, pressure and velocity of fluid in the pipeline.
  • Optimizing the Pump Size by calculating pumping costs vs. pipeline diameter for typical pipe materials.
  • Specifying surge suppression equipment to improve both the peak pressures and the overall operability of the pipeline. For example, determining the check valve size, type and dynamic performance needed to prevent check valve slam. Or specifying the best location for air valves and their sizing.

Surge Analysis services

ImageGrafix is a regional leader in surge analysis and dynamic simulation. Have performed services for all the major oil companies and consultants in the Middle East region.

This service is performed using Sunrise Systems PIPENET Software. PIPENET is a leader in Fluid Flow analysis and is being used and approved by leading consultants, Owner operators worldwide. Its not just the software which makes our service the best, but also The projects are handled by highly experienced consultants who carry a wealth of many years of similar experience.

Simulation and surge analysis give a wide range of benefits during design and operation. Once the computer models are built they can be used throughout a project’s life.

Tanker Loading Systems

The loading and unloading of tankers with petrochemical fluid ranging from crude oil to liquefied natural gas is a happening every moment throughout the world. However, it is an operation associated with the dangers of spillage, fire, explosion as well as the fury of the sea.
The design of a ship transfer facility is usually a compromise of loading times (demurrage) and construction cost. The overall combination of high flow rates, relatively short distances coupled with intermittent operation lead to high velocities. IMO regulations require transfer flow to be stopped rapidly in the event of any emergency, which usually means valve closures of less than 30s and the generation of high and rapidly applied surge pressures. Experience has shown that the potential for damage to pipework and hoses, spillage and failure of equipment can be easily realized
.

Firewater Systems

Firewater systems are essential to the safety of many areas within the oil, gas and petrochemicals industry. Due to the requirement to rapidly deliver large volumes of water to a specific area, high water velocities are often experienced, which in turn can lead to large surge pressures, both on start-up and shutdown.

Cooling Water Systems

The transfer of heat to and from process fluids is critical to the operation of most process plants. Cooling medium systems and heating medium systems are generally robust but there are a number of problems which can occur if these systems are not designed carefully, Such as Buckling of underground piping due to sub-atmospheric pressures following a ‘low pressure’ event such as trip of one or more pumps, Full vacuum in the highest elevation heat exchangers following pump trip, Excessive surge pressures when the pump is restarted and the vapour pockets collapsed and Surge pressures in excess of the piping design pressure, caused by:

    • emergency shutdown of a heat exchanger
    • rupture of a heat exchanger tube
    • pump trip and pump start-up
    • check valve slam and Fatigue failure caused by high piping vibration or excessive piping loads
