The key to pressure vessels
Software for pressure vessel design

VCLAVIS is innovative software for pressure vessel and heat exchanger design, developed by a team of experienced engineers. Designed to revolutionize the industry, it provides a totally new web based platform that enhances accessibility, efficiency, and compliance in pressure vessel engineering.

  • Accessibility & Convenience
    Users can access the software from anywhere with an internet connection. The need for local installations is eliminated, making the application ideal for remote teams, field engineers, and global operations. Cross-platform compatibility (Windows, macOS, Linux) ensures ease of use on different devices.
  • Real-Time Collaboration
    Engineers, designers, and inspectors can work on the same calculations simultaneously. Changes and updates are immediately available to all users, reducing miscommunication and version control issues. Cloud storage ensures that all calculations and reports are centrally managed.
  • Compliance with Industry Standards
    Ensures calculations adhere to ASME BPVC, EN13445, AD2000, PD5500, and other regulatory codes. Updates can be applied instantly to reflect changes in standards.
  • Improved Accuracy & Automation
    Automates complex calculations, reducing manual input errors. Includes built-in material databases, safety factors, and load conditions. Provides instant validation and alerts for non-compliant designs.
  • Security & Data Integrity
    Cloud-based backups prevent data loss. Secure access controls ensure only authorized personnel can use or modify calculations. Encryption and authentication mechanisms protect sensitive engineering data.
  • Cost-Effectiveness
    Eliminates the need for expensive proprietary desktop software. Reduces IT maintenance costs as updates and fixes are managed online. Subscription-based models make it scalable for small and large businesses.

    PD5500

    is a respected British standard for pressure vessel design, valued for its practical approach, detailed stress analysis, and proven safety principles. Unlike some modern codes, it retains a traditional yet effective design philosophy, making it particularly suited for conventional and high-integrity applications. While primarily used in the UK and Commonwealth regions, it remains internationally recognized and aligns with European regulations (PED 2014/68/EU). PD 5500 is ideal for manufacturers seeking a balance between established engineering practices, flexibility in material selection, and robust safety margins.

    AD2000

    is a well-established German standard for pressure vessel design, known for its strict safety requirements, detailed material specifications, and robust fabrication guidelines. It aligns with European Pressure Equipment Directive (PED 2014/68/EU), ensuring compliance within the EU market. With a modular structure, it allows flexibility in design while maintaining high safety margins. AD 2000 is widely used in Germany and Europe, making it a reliable and trusted choice for pressure vessel manufacturers aiming for safety, quality, and regulatory compliance. It remains the only code which allows designers to perform hand verifications.
