Pressure vessels are used around the world for a wide variety of applications, including water treatment, food manufacture, scientific research and industrial manufacturing.<\/p>\n

Such diversity means that the designs for individual applications are often unique or built in very low volumes, so creating these vessels requires flexibility as well as considerable manufacturing expertise.<\/p>\n

Although usually cylindrical, pressure vessels can be made in all shapes and sizes, with different shaped ends, or heads, and made from a variety of materials<\/figcaption><\/figure>\n

Pressurised containers are required to meet a variety of specifications and certifications in order to be deemed safe for operation and these must be followed closely by designers and manufacturers.<\/p>\n

In addition, there are extensive tests and quality control procedures that need to be in place.<\/p>\n

One company that has invested in both personnel and equipment for designing and manufacturing high quality pressurised vessels is ThermTech, which has a long history in precision steel manufacturing and cladding.<\/p>\n

Project design engineer at ThermTech<\/a><\/span>, Steven Griffiths describes some of the main considerations.<\/p>\n

It is important to select the most appropriate materials and manufacturing processes to achieve the most cost-effective pressure vessel.<\/p>\n

\u201cSmaller, lower pressure systems can often be created under sound engineering practice (SEP) but the safe operating limits need to be established and recorded. Information on this and the relevant standards for a project should be available from experienced manufacturers,\u201d says Griffiths.<\/p>\n

Due to the dangers associated with pressure vessels it is very important that they are designed and manufactured to the appropriate specifications.<\/p>\n

\u201cThese are usually specific to the market or country in which the vessel will be working, but very often customers will ask for it to be \u2018made to the code\u2019.\u201d<\/p>\n

Some may require heating coils, either internal or external, and with cladding to improve efficiency<\/figcaption><\/figure>\n

In North America this relates to the America Society of Mechanical Engineers (ASME) code but this contains many choices in terms of materials and design preferences. It does, however, stipulate welding processes, test procedures and quality control processes that need to be followed.<\/p>\n

\u201cAlthough usually cylindrical, pressure vessels can be made in all shapes and sizes, with different shaped ends, or heads, and made from a variety of materials.<\/p>\n

\u201cSome may require heating coils, either internal or external, and with cladding to improve efficiency.<\/p>\n

\u201cLaying out the requirements of the pressure vessel and discussing the various options with experienced designers will enable the most appropriate design to be established.<\/p>\n

\u201cFrom there, it is the manufacturing and testing process that will determine the quality and durability of the final product.\u201d
