Static Equipment design

We offer advanced mechanical design engineering services to customer that help them in developing complex design and products. Our service portfolio includes comprehensive designing of pressure vessels, heat exchangers, process columns and reactors. We have built up an extensive knowledge of the major code including ASME VIII- 1, ASME VIII-2, TEMA, EN 13445 and have ability to supplement these where necessary with individual company and industry specific requirement. Let’s discuss and collaborate for your success.

Pressure vessel includes equipment like separator, deaerators, storage tank, reactors, air receiver etc. We have extensive knowledge of design of pressure vessel including;

Design of pressure parts including nozzle, head, shell, support etc.
Material selection
Nozzle load design
Wind and seismic calculation
Optimized flange design
Non pressure parts design including lifting lug, saddle and skirt support.

We also undertake mechanical design of all types of heat exchanger and have designed most configuration listed in TEMA. We have extensive knowledge on optimum design of critical components of shell and tube heat exchanger including tubes, expansion bellow and tubesheet.

Optimum mechanical design of process column requires extensive knowledge of material selection, stability criteria, deflection check, wind and seismic analysis and vortex shedding criteria check. Our team has in depth knowledge of column design engineering starting from basic, extended basic, detail engineering and erection of column at site. This helps client to provide cost effective and flawless execution.

Finite element analysis

We have reach experience in carrying out finite element analysis across a wide range of engineering discipline fulfilling ASME, EN3445, ABSA and API 579 design by analysis requirement. Here are some of the most common cases where FEA is required to fulfill static equipment design.

Local loads on process nozzles which are outside code limits
Nozzle in the knuckle region
Cone to cylinder junction
Fitness for service assessment
Fatigue analysis of cyclic service vessel
Multiple support saddle analysis
Floating tank roof
Bolted flange connection
Tank bucking analysis
Consideration of nozzle loads on standard flange

We have performed several projects to perform FEA analysis to protect equipment against plastic collapse using commercial analysis software fulfilling ASME sec VIII and EN13445 requirement. Following are methods to evaluate protection against plastic collapse.

Elastic Stress Analysis Method
Limit-Load Method
Elastic-Plastic Stress Analysis Method

Applicability of each method require engineering judgment to apply which method shall be best fit for the problems. For example, application of the limit load or elastic-plastic analysis is recommended for cases where the categorization process may produce ambiguous results. Also, use of elastic stress analysis combined with stress classification may produce non-conservative results for heavy-wall (where radius to thickness ration is less than 4) pressure containing components, especially around structural discontinuities and is not recommended.

In addition to demonstrating protection against plastic collapse, the applicable local failure criteria and protection against collapse from buckling shall be satisfied to avoid buckling of components with a compressive stress field under applied design loads. For that we have comprehensive analysis guideline to performed buckling analysis using commercially available software.

Following are areas where analysis of pressure equipment to protect against local failure and buckling is required.

Buckling analysis for skirt/leg support vessel with large diameter to thickness ratio.
Local stress analysis at cone to shell junction for tall columns
Buckling analysis for rectangular vacuum vessels.
Bucking analysis for vacuum vessel.

IFatigue, a major source of product failure, can sometimes result in significant damage and injuries. A fatigue evaluation shall be performed if the component is subject to cyclic operation. The evaluation for fatigue is made on the basis of the number of applied cycles of a stress or strain range at a point in the component. The allowable number of cycles should be adequate for the specified number of cycles as given in the User’s Design Specification. As code formulae’s are not available to determine fatigue stress, FEA is acceptable tool for performing fatigue analysis.

We have performed variety of project to perform fatigue screening as specified in div 2 para 5.5.2, and as per EN 13445 to determine fatigue analysis requirements for integral and non integral components of equipment. We also have performed series of projects using Elastic Stress Analysis and Equivalent Stresses and Elastic Analysis and Structural Stress approach with guideline provided in ASME div-2.

CFD analysis

We offer, Computational Fluid Dynamics (CFD) services to solve various analyses related challenges faced by industries during the product development. Our Approach to problem solving is starts with proper understanding of physics of the problem and preparing a right solution strategy. Benchmarking with available analytical or experimental data, validation of results is crucial part of CFD simulation process. We are committed to provide accurate and reliable results.

Heat transfer analysis is one of the areas, where CFD can be used to solve the problems involving conduction, convection, and radiation. It helps in calculating the heat transfer coefficients of various types of flows, including natural, forced, and mixed convection. Also, more complicated heat transfer effects like viscous heating, phase change, evaporation, cavitation, and boiling can be included.

Following are area where CFD become powerful tool to optimize design in EPC industries

Temperature distribution evaluation
Flow distribution under the packed towers using Vapor Distributors / Chimney Trays
Flow simulation of burners and combustion chambers
Analysis of mixing of fluids
Heat transfer analysis of heat exchangers
