E2G|The Equity Engineering Group, Inc. has extensive experience in the design, specification, and optimization of pressurized equipment, including pressure vessels, piping, heat exchangers, furnaces, and storage tanks. E2G provides guidance regarding solutions to complex problems in order to maximize reliability and profitability, considering all aspects of the overall equipment life-cycle. E2G engineers hold membership on numerous Code committees and task groups within ASME and API. We continually strive to develop and implement the latest advancements in technology in order to maximize equipment reliability and control costs for owner-users.
Whether it requires closed form Design-By-Rule (DBR) methods (such as ASME Section VIII Division 1), or advanced FEA and Design-By-Analysis (DBA) procedures (such as ASME Section VIII Division 2), E2G is fully skilled, experienced, and capable of supporting our clients’ needs.
As an internationally recognized leader in the development of standards, E2G was selected as the lead investigator to ASME for the new ASME Boiler and Pressure Vessel Code, Section VIII Rules for Construction of Pressure Vessels, Division 2 Alternative Rules. E2G was responsible for introducing the latest developments in materials, design, fabrication, and inspection technologies. These technologies include new brittle fracture evaluation methods, new fatigue design methods, and a complete re-write and update of both the DBR and DBA procedures.
We have the knowledge and experience to implement and leverage the latest advancements in technology in order to maximize the value to our clients.
E2G routinely performs detailed piping flexibility analyses to support FFS evaluations or Code compliance checks in order to qualify sustained and thermal expansion loading conditions. When needed, we complete field walk-downs and generate isometric layout sketches of systems. We have extensive experience with aboveground and underground piping design Codes, such as ASME B31.1 Power Piping, ASME B31.3 Process Piping, ASME B31.4 Pipeline Transportation Systems for Liquid Hydrocarbons and Other Liquids, and ASME B31.8 Gas Transmission and Distribution Piping Systems. In the event a piping system does not meet Code requirements with its existing configuration, detailed plans can be provided to guide support or layout modifications, as appropriate, in order to ensure adequate support and flexibility while preventing excess reaction loads on equipment or restraints.
E2G performs nuclear design reports for new equipment designed to ASME Section VIII and Section III. Our nuclear quality assurance program meets all applicable ASME NQA-1 and 10 CFR 50 Appendix B requirements.
The process safety management (PSM) requirements in the Occupational Safety and Health Administration (OSHA) 1910 standards mandate that owner-users maintain essential documentation authenticating adequate design and maintenance of pressure vessels and storage tanks. Unfortunately, it is not uncommon to find equipment operating in industry with minimal or no documentation. This has become even more common in recent years with the re-purposing of assets for use in new facilities or services. E2G is fully qualified and experienced in completing “reverse engineering” or Suitability-For-Service (SFS) evaluations in the fastest and most cost-effective manner in order to achieve OSHA compliance for equipment lacking documentation.
E2G’s team of subject matter experts (SMEs) can provide third-party engineering reviews of project documents to ensure compliance with:
Utilizing industry experts who author, support, and develop RAGAGEP and corporate best practices, E2G SMEs will review project details such as:

E2G|The Equity Engineering Group, Inc. has extensive experience in post-construction repair of pressurized equipment. Our engineers regularly provide consulting on repair scoping and optimization, in addition to detailed design for both temporary and permanent repairs of pressurized fixed equipment items such as pressure vessels, piping, heat exchangers, furnaces, and storage tanks. We balance detailed engineering with practical experience in order to provide valuable solutions that maximize the overall effectiveness of a repair, considering all aspects of the equipment life cycle.
E2G is intimately familiar with all applicable post-construction codes and standards associated with repairs of pressurized equipment. We can provide detailed repair scopes that leverage state-of-the-art technology to supplement the guidance that is offered in codes and standards such as API 579 (Fitness-For-Service), NBIC (National Board Inspection Code), API 510 (Pressure Vessel Inspection Code: In-Service Inspection, Rating, Repair, and Alteration), API 570 (Piping Inspection Code: Inspection Repair, Alteration, and Rerating of In-service Piping Systems), API 653 (Tank Inspection, Repair, Alteration, and Reconstruction), and ASME PCC-2 (Repair of Pressure Equipment and Piping).
It is not uncommon for owner-users to perform local post-weld heat treatment (PWHT) operations following weld repairs to minimize weld residual stress and mitigate various damage mechanisms. Unfortunately, it is also not uncommon for local spot bullseye (or even some local circumferential band) heating to result in distortion or cracking. E2G can provide detailed engineering assessments, including advanced FEA if needed, to optimize PWHT arrangements and thermal gradients that will prevent detrimental distortion, cracking, or excessive residual stress. Additionally, our engineers can perform structural stability evaluations in order to determine whether supplemental support is necessary during the PWHT operation.
E2G actively maintains an ASME R-Stamp and performs numerous API 510 and NBIC certification evaluations for fixed equipment, including the modification and certification of ASME Section VIII Division 2 User’s Design Specifications (UDS) and Manufacturer’s Design Reports (MDR).
Rerates may be used to increase design, pressure, temperature, or corrosion allowance of pressurized equipment, as well as to decrease MDMT. If the vessel operates within the established rating, E2G can R-Stamp a vessel if no physical modifications are required. As documented in our Quality Control System approved by The National Board of Boiler and Pressure Vessel Inspectors, our certifications include alterations without physical modifications. In the event physical modifications are necessary, E2G can provide the design calculations and all applicable documents to the vendor responsible for the physical modification and application of the R-Stamp nameplate.
Per API 653 Paragraph 220.127.116.11, hydrostatic testing of a tank is not required when a repair has been reviewed and approved by an engineer experienced in storage tank design and a Fitness-For-Service (FFS) evaluation has been completed. The intent of the FFS evaluation is to determine the critical flaw size(s) at repair locations in order to ensure detection is feasible with mandatory Non-Destructive Examination (NDE). E2G is fully qualified and experienced in performing hydrotest exemption evaluations for storage tanks.
E2G has a staff of engineers and field specialists that can provide support for welding related issues such as the following:
Additionally, E2G routinely performs engineering evaluations (including implementation of Battelle Memorial Institute’s Investigation and Prediction of Cooling Rates during Pipeline Maintenance Welding) and optimizes weld parameter ranges to minimize the risk for potential burn-through and heat-affected zone (HAZ) cracking during in-service welding or hot taps.
In certain critical applications, E2G can also perform explicit weld simulations in order to gain a better understanding of the resulting residual stress, and can thus provide a better understanding of propensity for (and sensitivity to) cracking and other pertinent damage mechanisms.
Our Help Desk IT specialists and engineers are available for questions about all E2G products. Our goal is to facilitate upgrades and conversions, quickly answer your questions, and help you benefit from our state-of-the-art software products.
