How Pressure & Temperature Affect Pressure Vessel Design

Posted by Julian Vance-Daniel on Aug 17, 2017 3:00:00 PM

Pressure and temperature are arguably the most important factors to consider when designing a pressure vessel. Pressure and Volume of gases are linked and to a much lesser degree pressure and volume of liquids; pressure and boiling temperature of all fluids are linked. The two factors are therefore dealt with simultaneously by design engineers as two sides of the same coin.

Understanding Process Conditions in Pressure Vessels

Posted by Julian Vance-Daniel on Jul 26, 2017 4:15:00 PM

Process conditions play an important role in pressure vessel design, regardless of the type and style of equipment. Understanding the processes that take place within a pressure vessel allows you to;

  • Mitigate against potential safety risks
  • Sustain reliably high levels of performance
  • Minimise maintenance costs

Pressure Vessel Manufacture – How Simple Vessels Are Made

Posted by Julian Vance-Daniel on Jan 12, 2017 2:43:00 PM


Pressure vessels vary greatly in size and form, the simplest might be an aerosol can costing a few pence right up to huge nuclear reactor vessels costing many millions. Cylindrical pressure vessels have a fixed radius and thickness and are generally simpler to manufacture than spherical vessels. Common uses of cylindrical vessels are chemical reactors, boiler drums and heat exchangers. This article will cover the steps involved in making a cylindrical pressure vessel.

Pros & Cons of Super Duplex and Duplex Pressure Vessels

Posted by Julian Vance-Daniel on Jan 6, 2017 4:02:00 PM

Super duplex and duplex pressure vessels are becoming increasingly common due to a few factors. Super duplex and duplex steels are stronger materials than 3 Series stainless steels, this means that vessels will generally be manufactured from thinner plates and will therefore be lighter than stainless steel vessels. Duplex and particularly super duplex steels have a greater resistance to corrosion and are often favoured in marine environments.

Super duplex and duplex steels are more expensive than stainless steel – by perhaps 70% or more and are generally 5 or 6 times the cost of carbon steel. The weight saving and material saving offered through the use of duplex steels reduces the cost differential but generally duplex and super duplex vessels are more expensive than identical vessels in stainless and carbon steels.

What Is The Largest Pressure Vessel That Can Be Transported By Road In The UK?

Posted by Julian Vance-Daniel on Dec 2, 2016 4:15:00 PM


The design and manufacture of specialist pressure vessels can mean that special requirements for their transport is needed. For example, here at Vessco, we fabricate pressure vessels of up to 200mm in thickness, and at diameters of up to 5,500mm.

For comparison, the largest ever load transported on UK roads was a power station transformer weighing 640 tonnes. It travelled on a vehicle 100m long and 5m wide, taking up two lanes of the motorway.
