Equipment Engineering Services across Canada and USA


Little P.Eng. mechanical engineering team offers design services of pressure vessels, storage tanks, heat-exchangers, columns and chimneys. Our team has designed over 1000 pressure vessels and served industries including nuclear, defense (submarines), oil & gas, process plant and renewable energy. Our consistent high quality and cost-efficiency suit the needs of many clients that do not want to maintain an in-house pressure vessel engineering capability.


We offer the following analysis:

  • Heat-transfer analysis of heat exchangers, vibration analysis of heat transfer tubes

  • Pressure design and stability analysis of horizontal and vertical storage tanks

  • Pressure design of columns and chimneys, optimization of wall thickness, vibration analysis under wind and seismic load, hoisting analysis

  • Heat exchanger tube-sheet analysis and review

  • Storage tanks analysis (API 650, API 620 and EN 14015)

  • Finite element analysis (FEA) and review of non-standard equipment

  • Fitness-for-Service(API 579)

  • High temperature creep and fatigue analysis

  • Flange leakage and strength analysis

  • Air cooler tube-sheet and high pressure heater analysis

  • Spherical tank leg analysis

Design Codes and Standards:

ASME VIII-1,ASME VIII-2, TEMA, GOST, CODAP, RTOD, EN 13445, AD 2000, PD 5500, API620, API 650, API 579, EN 14015, GB 50341, GB 150, GB 151, JB 4732


Little P.Eng. Advantages:

  • Years of experiences in pressure vessel design and analysis.

  • Accuracy and safety are our top priorities

  • We use latest technologies: Codex, PV Elite, COMPRESS, AMETANK, TANK, ANSYS, ABQUS

  • Piping design in the project taken into consideration if applicable.

Client’s Benefits

  • Ensuring safe operability of pressure vessels

  • Saving on materials and manufacturing costs due to optimization of equipment wall thickness

  • Ensuring safety during lifting, installation and operation

  • When Little P.Eng. designs the entire project, the system design approach will reduce the impact caused by vibration of rotating equipment and pipes
