Industrial production requires not only qualified personnel to service machines, but also competent installers, commissioners and other equipment installation specialists. The launch of the plant and, accordingly, the owner’s costs depend on the quality and timing of installation. That is why the profession of an installer of technological equipment and related structures is so important in the labor market.

What does a process equipment installer do?

First you need to understand what technological equipment is. This is the name for any equipment that is needed for the production of material goods, be it household items, Food, Construction Materials, Components various devices etc.

Accordingly, a process equipment installer is engaged in assembling units and production lines that produce goods.

The range of these devices is extremely wide. Each branch of production has its own machines, conveyors and equipment. Moreover, they are often produced and adapted for each individual enterprise according to individual project. So this work cannot be called simple.

What exactly can the installer install:

    Units of hydraulic structures;

    Compressors, pumps and ventilation equipment, air conditioning systems;

    Metal cutting machines, forging and pressing equipment;

    Equipment for boiler rooms;

    Equipment for the food industry;

    Printing machines and components for printing production;

    Machines and units for construction industry;

    Textile machines;

    Refrigeration units;

    Lifting and transport equipment of intermittent and continuous action;

    Units of petrochemical industry enterprises, wood processing and pulp and paper mills.

As experience and qualifications increase, the number of machines is constantly growing, and the responsibilities of the installer increase.

At the beginning of his career, he is not allowed to independent work. A beginner will be entrusted with only a few auxiliary operations under the supervision of more experienced specialist. The internship stage at enterprises usually lasts from 60 to 114 days, after which we can already talk about employment.

Installers can work either alone, if the amount of work is not large, or as part of assembly teams. This applies to large-scale, large-scale units.

Qualification requirements for a process equipment installer

Any working profession requires good physical data, endurance, and the ability to work with your hands. All this fully applies to installers.

He needs:

    understand the structure of mounted machines and equipment;

    own any hand tools(drills, screwdrivers, electric saws, grinders, grinders, etc.);

    know the rules for safe slinging of loads, have rigging skills;

    have skills in large-scale assembly (equipment and units weighing over 10 tons);

    be able to test installed equipment and set it up.

In general, the profession of an installer is characterized by large volumes of work and strict deadlines for the delivery of objects (this condition is always stipulated in the contract). In addition, the specialist bears financial liability for equipment and units. In other words, he is required to be very disciplined, hardworking and skillful at work.

Where to learn to become a process equipment installer

For successful work The applicant's specialty requires secondary vocational education. Training is carried out in colleges and technical schools after finishing 9th or 11th grade high school. Terms vary from 3.1 years to 2.1 years with mandatory industrial practice and passing the qualifying exam.

However, given the breadth of the profession, already at the training stage there is a division into industries. As a result, a process equipment installer finds himself in demand in one particular industry.

An alternative option is to take professional retraining courses. However, in this case, it is necessary to have a basic working skill (fitter, mechanic, electrician, etc.).

Also, specialists in the installation of technological equipment are required to confirm their qualifications every five years.

Categories of process equipment installers according to ETKS

The Unified Tariff and Qualification Directory of Work and Professions of Workers includes six qualification levels in a given profession – from 2 to 7.

At the same time, it is possible to carry out independent assembly operations, as well as participate in equipment testing, only from the 4th category. With each new rank, the range of machines and assemblies that a specialist is allowed to assemble expands. Ultimately, a highly qualified worker receives the skills to assemble equipment from large parts (over 10 tons), as well as the right to manage a team of installers.

How much do process equipment installers earn?

In terms of wages and demand, the situation is ambiguous. Qualified specialists with extensive experience are in great demand among employers. The average salary of such specialists ranges from 55 to 60 thousand rubles. With low qualifications, you can only count on 30 thousand rubles per month.
