PRESSURE VESSEL
What Is a Pressure Vessel?
A pressure vessel is a closed container designed to hold liquids or gases at a pressure substantially higher or lower than the ambient pressure.
Why A Stainless Steel Pressure Vessel?
Stainless steel pressure vessels can stand up to very high pressures without deformation, fracture, or fatigue. The resistance of stainless steel to corrosion and its durability make it the ideal material to handle chemicals, liquids and food products. In addition to this, stainless steel is an easy and cost-effective metal to clean and maintain. So stainless steel is the top choice for pressure vessels used in clean and sterile environments.
At TEC-SIM, pressure vessel design relies on our technical-engineering skills and our in-depth knowledge of the latest design and project development software…
TEC-SIM’s pressure vessel manufacturing is tailor-made so any structural detail can be customised with high precision and attention to detail according to customer specifications…
Why Do Pressure Vessels Need Careful Design?
Pressure vessels must be designed to withstand the difference between internal and external pressure. The difference in pressure between inside and outside creates a state of tension in the manufacturing material. So engineers need to design vessels resistant to this state of tension, without stresses which can be the cause of leaks, breakages or dangerous situations for people and things such as explosions.
Which Parameters Should Be Considered When Designing Pressure Vessels?
Pressure is the most important operating parameter, even though there are others. For example, the operating temperature influences the mechanical properties of materials and can cause permanent deformations. Another dimensioning parameter depends on the fluids in contact with the vessel, which can cause chemical attacks on materials such as corrosion or embrittlement.
According to costs and project constraints (e.g. maximum size or need for nozzles), engineers can act on these parameters:
TEC-SIM designs and manufactures according to the main pressure vessel standards in use internationally, such as PED, ASME and SELO…
TEC-SIM’s pressure vessel repair service aims to guarantee best performance, prevent machine downtime and comply with regulatory compliance…
What Are The Reference Standards for Pressure Vessels?
Although differing in some details, all regulations for pressure vessels agree on some construction requirements:
- use of materials from controlled and certified origin
- use of qualified and verified construction procedures
- carrying out non-destructive tests before using the container
The regulatory reference for designing, manufacturing and using pressure equipment in the European market is the PED (Pressure Equipment Directive) 2014/68/EU product directive.
