VCLAVIS has been updated to incorporate new bracket verification module per EN13445-3: 2021 +A1:2026. Moreover rectangular flange calculations (including blind ends with additional peripheral moments) as per PD5500 EC143 have been added in Calculation Collections, and are […]
Modern pressure vessel software has evolved far beyond basic code compliance checks, becoming a fully integrated engineering environment where structural integrity, piping interactions, and design governance converge. One of the most significant advancements in this space is […]
VCLAVIS has been updated to incorporate alternative cone calculations per EN13445-3:2021 +A1:2026 introducing application of chapter 16.15. Moreover, due to Code similarity with PD5500, the method is also made available at the PD5500 module as an additional […]
Pressure vessels are critical components in industries ranging from oil and gas to pharmaceuticals, where their safety and reliability are paramount. To ensure their stability throughout their lifecycle, it is essential to consider not just their design […]
VCLAVIS Has been fully updated to incorporate ASME VIIII DIV.1: 2025 Code, introducing new Pressure – Temperature Ratings for ASME B16.5 and ASME B16.47 flanges and new rigorous flange calculations per ASME VIIII DIV.2. All changes applied […]
Designing static equipment in accordance with ASME Boiler and Pressure Vessel Code, Section VIII, Division 1 (ASME VIII DIV.1) requires careful consideration of material toughness, especially for vessels operating in low-temperature environments. Impact testing, typically Charpy V-notch, […]
Thin cylindrical shells under external pressure – such as those found in vacuum vessels, underwater pipelines, and jackets – are vulnerable to elastic buckling. The safe design of such shells is addressed by two main regulatory traditions: […]
Introduction Nozzle local load analysis is a critical aspect of pressure vessel and piping design. External forces and moments from connected piping can significantly impact the integrity of the nozzle-shell junction, potentially leading to failure if not […]
Introduction Nozzle openings in pressure vessels weaken the pressure boundary, requiring adequate compensation to maintain structural integrity. Examination of nozzles is a critical part in pressure vessel calculations, hence this article examines the main methods for nozzle […]
VCLAVIS Software official version is released. All interested users may simply subscribe on app.vclavis.com and use the software for free for one month. New subscriptions shall receive full support from our Engineers in order to master the […]
Pressure vessel analysis traditionally focuses on containing gases or liquids, where pressure calculations are well-established. However, when handling bulk materials such as pellets, powders, or granules, the pressure distribution inside the vessel differs significantly from that of […]
Verification under external pressure is one of the most critical aspects of pressure vessel design due to the risk of elastic or inelastic buckling. The ASME Boiler and Pressure Vessel Code (BPVC) provides two primary divisions for […]
VCLAVIS – Software for Pressure Vessel Design, is proud to announce the launch of its new VCLAVIS AI Assistant, an integrated chat feature powered by OpenAI. This groundbreaking update is designed to transform how users interact with […]
Examine printed output and learn how to evaluate the reports.
Adding the rest of the shell components. Shell flanges at cover, shell cover cylinder and head. With these components the heat exchanger body is complete.
Adding the rest of the channel components. Channel cylinder, body flange at cover, and channel cover (blind)
Proceed in calculating a floating head attached on the floating tubesheet. Typical AES formation.
Create a tube bundle and evaluate it. Attach the bundle on the stationary tubesheet and proceed in creating the floating tubesheet.
Learn how to intersect the tubesheet among the shell and channel body flanges. Learn how to create a tubesheet.
Calculate the channel flange at tubesheet. Along with the shell flange, these two entrap the tubesheet. See how the flanges affect each other. Calculate both flanges for the worst case scenario.
Calculate the main shell and the first flange connected on the stationary tubesheet of AES heat exchanger. Use rigorous flange analysis.
We’re excited to introduce the latest update to the VCLAVIS app, delivering a refreshed look, enhanced performance, and an improved user experience across the board – alongside a major behind-the-scenes upgrade to our core technology. This version […]
EN 13445 code is the European standard for the design and construction of unfired pressure vessels, ensuring safety and performance through rigorous material selection, design calculations, and testing procedures. While the code provides a comprehensive framework for […]
