Pressure Vessel Engineering and Design Services Company (CRN application, ASME / PED registration)

Meena Development LTD. engineers and designs pressure vessels. We deliver complete design support for pressure vessel fabrication companies and design engineering firms to develop robust pressure vessel drawings and designs to avoid accidents. Our pressure vessels design conform with the following:

  • CRN number application package in Canada provinces

  • ASME registration documents package

  • PED registration in the CE (Europe) package

Our pressure vessel design services include development of pressure vessel AutoCAD drawings, 3D models in SolidWorks, custom vessel modeling using Inventor, and design analysis of various types of industrial vessels. We ensure that the final designed and fabricated pressure vessel meet the safety standards and avoid any operational hazards by developing the fabrication drawings that adhere to ASME codes written under Section VIII Division 2.

For over 25+ years in engineering services outsourcing services with have collaborated with pressure vessel fabricators and design engineers across industries including oil & gas industry, processing plants, nuclear, food processing, chemicals and pharmaceutical to deliver CAD drafting services.

Our diversified experience helps us deliver 2D and 3D drawing followed by FEA analysis of CAD models through design by analysis approach to ensure that the designs stay within safety limits.

Our firm specializes in ASME code pressure vessel engineering and design services. Types of ASME compliant pressure vessels and tanks that we engineer and design include the following:

ASME Code Compliant Tanks and Pressure Vessels

  • pressurized tanks

  • pressure vessels

  • boiler steam drums

  • specialized boilers for the power generation industry

  • sight glasses

  • forged parts

Our area of specialization in pressure vessel design services:

  • Pressure vessel PDF drawing conversion to AutoCAD and solid modeling for analysis

  • 2D Installation, assembly and detailed manufacturing drawings for welders, fabricators, site operators etc.

  • Design, draw and plan the appropriate layout vessels for optimum performance

  • Pressure boundary conditions for pressure vessels and heat exchangers

  • Bespoke designing for same day fabrication with Autodesk Inventor illogic

  • Heat transfer and fluid flow studies using CFD

  • Pressure vessel design analysis and obtaining proofs of design concept

  • Platform/equipment asset life assessment

  • Evaluation of stress formation and concentration for critical part identification

  • Hydro-tests, buckling, etc. for thick-walled pressure vessel and piping systems

We are the leading pressure vessel design consulting company, based in Calgary, Alberta; Vancouver, BC; Toronto, Ontario; Buena Park, California, delivering pressure vessel design, analysis, proofs of designs, FEA and CFD plots, temperature and velocity profile, and inspection to ensure design stability. We help fabricators avoid redesigning and help save the costs of reworks during manufacturing.

We specialize in delivering a range of pressure vessel drawings:

  • Pressurized tanks and settler vessels

  • Boilers and heat exchangers

  • Steam drums, knock out pots

  • Storage tanks: Above the ground, flash tanks

  • Oil and gas pressure vessels

  • Processing tanks, cooling tanks and heaters

  • Jacketed vessels, silos, columns etc.

  • Compressed air tanks, filter tanks

  • Cyclone separators, filters, blow down tanks, etc.

  • Pipes, headers, risers, shells, assemblies & mountings

Our global presence across the USA, Canada and Arabian Gulf Countries, etc. helps us in reaching our clients quickly for onshore as well as offshore pressure vessel design and drawing solutions.


Canadian Registration Number (CRN)

The CRN (Canadian Registration Number) system is the Canadian method of reviewing and registering the design of pressure vessels, piping systems and the fittings used to make them.

  • All Canadian provinces and territories, collectively called jurisdictions, use the CRN system.

  • The system is governed by the general CSA B51 standard, but every jurisdiction adds their own specific rules to make the standard enforceable.

  • The B51 standard is not a stand alone design code. ASME codes like VIII-1 and B31.3 provide the design and production methods. B51 adds some more rules specific to Canada.

  • Ideally design review and QC acceptance is completed prior to construction. It must be done prior to use.

  • CRN registration is required for each jurisdiction where the equipment is used.

  • Once registered, fabrication and inspection is handled the same as with National Board production.

  • Once registered any number of identical vessels or fittings can be produced.

  • CRN registered products can be built anywhere in the world.

Issues that regularly arise with CRN registration:

  • Fittings must be designed to a code like B31.3 and built under a QC program.

  • Vessels need to be fully compliant to the current code rules, including details like weld sizes and inspection openings.

  • It is reasonable to budget a half year for design registration in all jurisdictions. Typical times are less, but it can take longer.

  • CRN specific knowledge is required for successful registration – some is documented, and some is not.

  • A design is reviewed seven times if it will be used Canada wide. A failure in one jurisdiction can lead to redesign and restarting the whole process. It is important to design conservatively.

  • It can be hard to find registered fittings for use in vessels and piping systems.

  • Registration fees are much higher than National Board fees.

It is important to understand this when planning pressure equipment for Canada. The pages below are resources and an introduction to the CRN system. Pressure Vessel Engineering offers extensive design and CRN registration services. Our advertisement is at the bottom of the page.
