Flange connections

assembly of flange connections

Flange connections They are distinguished by easy assembly, the possibility of replacing parts and the strength of connections. Certain conditions must be met for the flange connection to be tight. Combined flanges should have similar connection dimensions, not exceeding the permissible tolerance. Another condition is periodic tightening of connections in order to maintain tightness of bolted connections. This is especially important as they are constantly exposed to mechanical vibrations or the significant fluctuations in temperature and humidity in the environment. Flange connections consist of: a flange, a set of fasteners - bolts, nuts, washers and a gasket. Their main task is to connect parts of the pipeline or, if necessary, to attach additional equipment to the pipe. They are available in one-piece and loosely fitted versions. One-piece ones withstand well the loads made together with the reinforcement during stamping and casting. Loose flanges are outer discs attached to the flange or to the edge of the pipe. These types of elements are not difficult to assemble, but they are less durable.

What are the types of flange connections?

Depending on the method of fastening flange connections, we can distinguish several types:

Welded flanges

They are used on steel pipelines and to connect devices. These are flat rings welded to the edge of the shell around its entire circumference. They can also be equipped with a locking ring.

Loose flanges on the weld ring

They consist of two parts - the flange itself and a ring that is welded to the pipe. This design is convenient to install. They are mainly used with metals such as copper and aluminum.

Clamp flanges

The joints are mounted close to each other. They are used for enameled metal structures. They help to maintain the right temperature when firing enamel.

Threaded flanges

It is used on assemblies and devices where the use of welding is undesirable, as well as in places requiring easy disassembly. They withstand high pressure.

Training in the assembly of flange connections

The assembly of flange connections may only be performed by a person with appropriate competences and skills, as well as authorizations. The permit to perform these works is issued by the Office of Technical Inspection. These qualifications can be obtained by completing the assembly course of flange connections and by taking an exam that tests knowledge and skills. Due to this, we have prepared a training in the assembly and operation of flange connections. Well-made flange connections enable long-term operation of tanks and pipelines, as well as their tightness and reliability. Our training company can boast of many years of experience in conducting professional training in the field of flange connections. We have obtained a UTD certificate allowing us to conduct training and examinations as well as recognition of the training center, which was issued by TÜV Akademia Polska. The course is intended for people who deal with the assembly of flanged connections and people who control and supervise these works. Our offer includes basic and intermediate level training. In the theory course, you will gain knowledge covering the types of flange connections, how to safely install and remove them, as well as the functions and types of gaskets. In practice, you will practice the skills of choosing the right gaskets and making and checking flange connections. The training aims to acquire theoretical knowledge as well as practical skills on how to properly install and safely use pressure equipment. Safety, productivity and work accuracy are particularly important during our classes. We provide professional support and consultations with specialists, as well as training materials. The training program includes theoretical and practical classes.

Type of classesDescription
TheoreticalThe theoretical part covers such issues as: types of flange connections, types and functionality of gaskets and their relative features, types and causes of faults, types of bolt loads and gasket stresses, identification of faults and failures, types and construction of hydraulic wrenches, preparation of the sealing surface, rules of safe assembly and disassembly as well as occupational health and safety measures required when performing these activities.
PracticalDuring the practical classes, students will practically install flange connections. They will learn how to select personal protective equipment as well as control and select gaskets. They will learn what the sequence of actions related to the assembly and disassembly of connections is, and will also test their tightness.


At the end of the course, there is a theoretical and practical exam. After obtaining a positive result, students receive a certificate issued by TÜV, which authorizes them to install flange connections.

Classes can be held stationary at the company's headquarters or it is possible to organize classes in a place proposed by the client. Our offer also includes online training. These types of classes include a theoretical part, a practical part and an exam that requires work at the position.
