What is the connection of plastic pipelines
Systems based on thermoplastics are widely used in utility transmission systems and industrial solutions. Materials such as PE, PP, PVC or PVDF make it possible to build systems that are resistant to chemical agents and varying operating conditions. In such applications, it is not only the choice of components that is important, but also the way in which they are permanently connected. The process is based on the controlled interaction of temperature and working parameters, which affect the quality of the welded joint.
Pipeline joining requires repeatable conditions and accuracy at every stage of pipe and fitting preparation. It is essential that the surfaces are properly matched, the parameters are stabilised and the process is carried out according to accepted technical requirements. In practice, this means knowing the material and maintaining the right proportions between temperature, time and pressure. A correctly made connection is an integral part of the installation and determines its further use.
Scope of training and materials used in the work
The training covers the preparation and making of connections in thermoplastic pipework, based on solutions used in industry practice. During the course, we work with piping materials such as polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC) and polyvinylidene fluoride (PVDF). Each has different properties, which affect how the components are prepared and the joining process. The differences between the materials also translate into their use in installations with different performance requirements.
For whom the training is intended
Welding course piping is aimed at people who plan to work in the manufacture or supervision of thermoplastic installations. Participants include fitters, installation company employees, newcomers to the industry and professionals responsible for quality control and technical acceptance. The training responds to the needs of both those gaining their first experience and those wishing to structure their competence in a specific area.
The scope of the classes is tailored to the nature of the work being carried out, so the programme takes into account the different roles that occur when carrying out installations. Some participants concentrate on making connections and operating equipment, while others focus on controlling parameters, assessing quality and documenting workflows. This division allows participants to better prepare themselves for the responsibilities of their specific position.
Welder and supervision in pipeline work
In installation projects, there are two distinct areas of responsibility that require different preparation and approaches to the tasks performed. This division is based on the nature of the work and the requirements for quality and process control.
The welder is responsible for making the joint in accordance with the agreed parameters and preparing the parts for the joining process. The work involves operating the equipment, checking the technical conditions and evaluating the completed weld at the implementation stage. It requires accuracy, repeatability and knowledge of the material.
Supervision focuses on checking the compliance of the implementation with the stipulations and requirements of the technical documentation. Responsibilities include verification of process parameters, the completeness of records and the progress of work in the various stages of the installation. He/she does not make the connections, but is responsible for their acceptance and release for further use.
Piping connection methods used in installations
Various connection methods are used in thermoplastic installations, selected according to the type of material, diameter and operating conditions. Each method is based on different parameters and requires different preparation of the components.
The most commonly used methods are butt and electrofusion welding. The former involves heating the pipe ends and joining them under pressure, which is used for larger diameters and pressure installations. Electrofusion welding, on the other hand, uses fittings with a heating element that enable the joint to be made by controlled heating of the material at the interface.
Other solutions, such as infrared (IR) welding, used in environments with higher cleanliness requirements, or techniques designed to work with non-standard-sized components, are also used in more demanding installations.
What the training looks like
The training combines theoretical preparation with work on training benches replicating the conditions encountered in the realisation of installations. At XYZ, classes cover the preparation of pipes and fittings, setting parameters and making connections according to accepted technical requirements. Participants work on the equipment used in the industry, which allows them to better understand the process and the relationships between its various elements.
During the exercises, particular attention is paid to the correct preparation of pipes and fittings, the stability of parameters and the repeatability of the connections made. We also analyse situations that may arise during installation, including deviations from assumptions and their impact on the final result. This way of teaching helps to structure the knowledge and transfer it to the working conditions encountered in installation projects.
Certification and awarding rules
The thermoplastic pipe jointing qualification is granted for a specific scope of work, in accordance with the requirements of EN 13067. This means that the qualification is not of a general nature and always relates to the specific conditions under which the joints are made. In practice, the scope of the qualification is closely linked to the working method, the type of material and the specifics of the installation.
During training, we prepare for work in the chosen area, paying attention to the conformity of the connections made with technical requirements and documentation. The scope of the qualification is clearly defined and application-specific, allowing us to tailor the qualification to the nature of the work to be carried out.
Terms of reference - what exactly does the certificate cover
The certificate confirms that you are prepared to work in a specific area and is always assigned to specific call conditions. It encompasses several elements that together define where and in which situations the acquired qualification can be applied.
The terms of reference specify:
- connection method - e.g. butt welding or electrofusion welding,
- material type - e.g. PE, PP, PVC or PVDF,
- diameter range - consistent with the parameters on which the examination was performed,
- type of installation - e.g. networks or process installations,
- job - welder or supervisor.
This way of defining qualifications makes it possible to match the scope of qualifications to the actual working conditions and the nature of the installations performed.
Examination and certification options
At the end of the training, there will be a review of the skills acquired, which will allow you to test your preparedness for making connections in practice. The examination includes a theoretical part and tasks performed on the training bench, in which it is important to observe the parameters and correctly prepare the installation components.
Depending on the scope chosen, it is possible to take examinations administered by external bodies such as UDT or TÜV. The form of confirmation of qualification is tailored to the planned area of work and the requirements for fieldwork.
Where plastic piping is used
Pipelines made of thermoplastic materials are used in various technical areas where durability and resistance to chemical agents and operating conditions are important. They are used in infrastructure solutions and industrial installations for a variety of applications.
In practice, they are used, among others, in water and sewage networks, utility transmission systems, technological installations and in environments requiring increased material resistance. The range of applications depends on the properties of the material used and how the connections are made.
Organisation of training and working conditions
Training is delivered in a facility equipped with workstations that allow you to work on equipment used in the industry. Classes are conducted under conditions that mimic typical situations encountered in the construction of pipelines, which allows us to focus on the correct preparation of components, the stable conduct of the process and the thorough practising of individual activities. In justified cases, it is also possible to organise training at a location indicated by the customer, provided that the technical conditions and scope of the training allow this.
