The KEE Experience


KEE Engineering provides professional services for pressure vessel fabricators, petrochemical projects, turnaround projects and mechanical design and analysis.

Pressure Vessels and Heat Exchanger Design

KEE Engineering provides all engineering and all non-manual functions for pressure vessel fabrication including design, calculations, drawings, material selection and shop documentation.

  • Support pre-bid and post contract award meetings as requested
  • Create preliminary drawings
  • Participate in proposal preparation
    Post Contract Award
  • Attend kickoff meeting
  • Create design calculations to ASME code with Compress software
  • Documentation with Autodesk Inventor software to company’s QA manual
  • Bill of Material (BOM) and purchase specifications
  • Incorporate Client and end user comments into calculations and drawings
    Fabrication Support
  • Design review meeting with fabrication team before release
  • Review of material quotations for technical compliance
  • Review of material test reports (MTRs) for technical compliance
  • Create fabrication tracker and fabrication documentation
  • Response to inquiries regarding drawing during fabrication
  • Evaluation and incorporation of change request during fabrication
  • Preparation of pressure test procedure and records
    Authorized Inspection
  • Conduct pre-review of documents
  • Participate in the Authorized Inspections
  • Create the U1, U5 and U2 manufacturing date forms as required

Division 2 Designs

KEE Engineering uses state of the art software programs to document design including Compress and non-linear Finite Element Analysis for Division 2 designs.

If your fabrication facility has a Division 1 “U-Stamp” but not a Division 2 “U-2 stamp” KEE’s professional mechanical engineering and quality department can provide teams to upgrade your facility to Division 2.

Division 2 vessels will expand your market and increase your profits because Division 2 vessels are significantly lighter saving on material costs, welding costs and handling costs that far outweigh the additional non-manual costs.

Services offered by KEE Engineering for pressure vessels and heat exchanges include:

  • Division 1 and Division 2 calculations
  • Fabrication Drawings
  • Procurement specifications
  • Evaluation of proposal submittals for code compliance
  • Weld procedures, Procedure qualification and Welder qualification
  • Evaluation of Fabrication change request
  • Pressure testing procedures and documentation
  • Preparation of ASME forms
  • Preparation of documentation for Authorized Inspector (AI)
  • Pre AI-inspection review
  • Manage AI review


Pressure vessel repair is often scheduled during plant outages and the extent of the repair is often discovered during the outage. Proper planning will minimize the potential of costly extension of outage time. KEE Engineering can provide worst case scenario planning during pre-outage planning to ensure that all material, procedures and contractors are available to minimize the time required for unforeseen repairs.

Engineering Support

KEE Engineering’s teams can provided support in the following areas:

  • Engineering scaffolding design as required by OSHA
  • Design of temporary supports with scaffolding or structural steel
  • Pressure test specifications, procedures and documentation
  • Engineered pressure test caps that can be fabricated in the field
  • Critical lift design and documentation
  • Design of special lifting lugs, trunnions, and spreader bars


KEE Engineering uses state of the art parametric solid modeling software and finite element software to optimize design of new products and review for potential improvements to existing products. For new product design, the process shortens the design cycle, ensures designs meet code requirements optimizes fabrication and minimizes the requirements for prototypes. For existing design, KEE Engineering analysis can identify opportunities for costs savings as well as extension of fatigue life and failure analysis.
