PRESSURE VESSEL DESIGN

​

  Pressure Vessel Design According to ASME Sec VIII Div 1

​

In the world of engineering, particularly in industries like oil and gas, chemical processing, and power generation, pressure vessel design is a critical aspect ensuring safety, reliability, and efficiency. When it comes to designing pressure vessels, adherence to standards is paramount. Among these, the ASME Boiler and Pressure Vessel Code, specifically Section VIII Division 1, stands as a cornerstone for ensuring the integrity of pressure vessel designs.

ASME Section VIII Division 1 provides requirements for the design, fabrication, inspection, testing, and certification of pressure vessels operating at internal or external pressures exceeding 15 psi. This standard is recognized globally for ensuring the safety of pressure vessels under various operating conditions.

​

1. Design Calculations: ASME Sec VIII Div 1 outlines detailed calculations for determining the thickness of pressure vessel components, such as shells, heads, and nozzles. These calculations involve considerations for internal and external pressure, as well as additional loads such as wind and seismic forces. Engineering wisdom entails meticulous calculation and validation to ensure structural integrity.

1. Welding Procedures: Welding is a critical aspect of pressure vessel fabrication. ASME standards prescribe welding procedures, qualifications, and inspection requirements to ensure the quality and integrity of welds. Wisdom in engineering lies in selecting appropriate welding techniques and ensuring compliance with ASME guidelines.

2. Non-Destructive Testing (NDT): NDT methods, such as ultrasonic testing (UT), radiographic testing (RT), and magnetic particle testing (MT), are employed to detect defects in pressure vessel components without causing damage. Engineering wisdom involves selecting suitable NDT methods based on the material, geometry, and criticality of components.

3. Pressure Relief Devices: Pressure relief devices, such as safety valves and rupture discs, are essential for protecting pressure vessels from overpressure conditions. ASME Sec VIII Div 1 mandates the sizing, selection, and installation of these devices based on design parameters and codes. Wisdom in engineering entails ensuring proper sizing and configuration of pressure relief devices to safeguard against potential hazards.

Conclusion

In the realm of pressure vessel design, engineering wisdom goes beyond mere compliance with standards. It involves a deep understanding of materials, structural mechanics, and operational considerations to ensure the safety, reliability, and efficiency of pressure vessels. Adhering to ASME Section VIII Division 1 is not merely a regulatory requirement but a testament to the commitment of engineers to uphold the highest standards of integrity and professionalism in their designs.

Commissioning a bespoke pressure vessel design  isn’t easy. Codes like the ASME BPVC give you rough guidelines to follow, but there's still a lot to think about. From head type to the type and thickness of the lining, the choices you make will have a profound impact on the performance and durability of the finished product - which is why it’s important to pick a manufacturer that knows exactly what they’re doing. 

That’s where we come in. Since acquiring Yorkshire-based pressure vessel design specialists Whiteley Read in 2018, we’ve had the capability to design and engineering high-integrity pressure vessels for a range of oil & gas industry clients – including EPC companies and blue-chip giants like BP..

We also design high-integrity carbon capture and storage vessels for companies that are in the process of improving their green credentials.

PRESSURE VESSEL DESIGN HIGH PRESSURE

​

We specialise in the design and engineering of thick-walled pressure vessels – using our extensive knowledge of exotic materials to fabricate units that can withstand pressures in excess of 460 barg.  

We’re also one of a select handful of design that know how to manufacture using 500-QT steel and we’re well-versed at building vessels that are lined with corrosion resistant materials (CRMs) like Austenitic or Duplex Stainless Steel for units that need to be installed in inhospitable environments.
