What is flange fitting?

It is worth starting with what the flange connection itself is. A flanged connection consists of two opposing, coaxial flanges. These flanges are connected by at least four bolts, usually with a gasket between them. They are the most common type of joint used in industry, for example to connect sections of piping or flexible hoses. It is worth knowing this definition in order to understand what we are talking about and to be able to find out more. What is most important in installations or pressure equipment is, of course, the flange connection, but it is important that these are disconnected! When planning an installation, attention must be paid to the selection of the flange connection. Only a well-chosen connection is responsible for safety and long service life. It is also worth knowing and complying with the requirements of the European Pressure Directive. It is the PED which specifies that flange connections it is essential that they are installed by qualified and certified persons! Keep this in mind! Older constructions are characterised by asbestos seals, whereas today this is unthinkable, as asbestos is banned! A typical feature of modern seals is the completely different performance in terms of materials and design, hence the need for applied calculations.

Student learning to assemble

What are today's flanged joints made of? They are made using a flat gasket that sits between the flange planes!

Such a collar can be integral:

  • Moulded part which is part of a jointed element
  • Can be a loose flange, e.g. superimposed on a sleeve
  • Or serve to weld 

The safe operation of tanks as well as pipelines depends on the quality of the flanged connections. Therefore, the accuracy, professionalism and other qualifications of the fitters are very important. With these skills, durable and leak-free flanged connections can be made.

Knowledge and skill are very important qualities of a good flange fitter. However, not everyone knows what flange connections are used for. Well, they are essential for connecting fittings, pipes and tubes. They are used in many industries, for example in oil refineries, the chemical industry, the food industry and the energy sector.

In order to carry out the assembly and disassembly of a flange connection using the appropriate gaskets and bolts, you must be knowledgeable and skilled.

A handful of useful information on flange joint construction:

Flanged joints are coaxial, opposing flanges that are connected using four (or more) bolts.

The essential elements are:

  • two axisymmetric steel flanges,
  • seals,
  • connecting elements - these are the appropriate bolts and nuts that fit into the overall structure.

There is a fairly general description of the construction.

About the training

Graphics of pipes with flanged connectionsIt is through the training that one gains a certificate, attesting to one's skills and entitlement to make flanged connections.

Who is the training for?

The following formal requirements must be met in order to enrol for training:

  • at least 18 years old
  • minimum basic education

Therefore, if you are thinking of making flanged joints or are or want to be on the staff supervising and inspecting their installation, choose our training!

What is the purpose of the training?

The aim of the training is first and foremost to learn skills! During the course, trainees will acquire theoretical and practical knowledge on the proper installation and safe operation of pressure equipment in various industries.

What about the exam and the certificate?

After passing the examination, the student will be certified as a flange fitter! The validity of this certificate is 5 years, after which the certificate must be renewed. The examination consists of a practical and a theoretical part. As mentioned above, the certificate entitles you to install flange connections in Poland and other EU countries.
