I produced components for mobile phone antennas, performed the operations of measuring, marking, cherneruire, drilling and cutting. Cutting of materials was performed with oxy-acetylene flame machine, grinder, with electric saw and a cutting machine with abrasive stone. I performed cutting at an angle of 45 degrees, straight and chamfer. After cutting all the parts I cleaned them of slag, polish them, then assembled them in conformity with a draft containing values and the part was manufactured; I also produced access stairs for antennas made of angle iron of 40-50 mm and steel stairs with the diameter of 16 mm; I arranged a template at the work bench, fixed pieces of angle iron with a 6 m length into a holding device, aligned them and introduced steps with the of 450 mm long, made of steel; I aftuire them with electric welding machine, after which they were transported for final welding, they were actually some scale segments, which were provided at each end with two holes in order to be connected together using iron plates. I also produced pillars of pipe with diameter of 76 mm and 89 mm, with length of 6 m; the pipe ends were provided with flange and pipes of 1/2" were mounted between them; these were bent, lattice shaped; after their aftuire, I welded them permanently, then pickled in acid bath. The materials used for antenna components were: pipe of 30 mm, 42 mm, 76 mm, 89 mm, 108 mm, 114 mm, 133 mm, 168 mm, 219 mm, with wall thickness of 3 mm, 5 mm, 8 mm, 10 mm rectangular pipe of 30 mm, 40 mm, 50 mm, 60 mm, angle of side of 30 mm, 40 mm, 50 mm, 60 mm, 70 mm, 80 mm, 100 mm; U profile of 65 mm, 80 mm, 100 mm, 120 mm, 180 mm, 200 mm, H profile of 80 mm, 100 mm, 120 mm, 180 mm, 200 mm, 250 mm; I profile of the same size; band of 20 mm to 80 mm. In addition to these works I also performed repair operations of pickling to the plant heating installation when needed.
During the period I worked in this company I performed installation and repair works at several plants. Here I was part of a team of 4 workers, 3 of them were Italian. First I participated in construction of a power plant in the town Tavazzano. I worked on installing a boiler with a height of 35 m to produce electricity. We started with metal structure: mounting metal pillars, metal beams, access stairs, lattices, walkways, railings. We used various types of equipment and materials: U profile, I profile, H profile of different sizes from 65 mm to 300 mm, angle of 30 mm to 80 mm, laminated sheet of 5 mm, 10 mm, 14 mm , band from 20 mm to 60 mm width and thickness from 3 mm to 6 mm. After completing installation of metal structure I started the installation of plant pipes and equipment, choosing positions, valves, taps, flanges, seals, I was preparing them, meaning measuring, tracing, cutting, gauging them, then started mounting them in conformity with the layout . On the position it was written the spul number, size and line where it was mounted. Equipment and materials used: closing-opening cocks with valves, size from 15 mm - 100 mm, pn. 18 bar, ball valves, butterfly valves, safety valves, elbows of 45 degree, 90, 180 degrees, from 1" to 20"; curves, concentric reducers, eccentric reducers, small Ts, equal Ts. For this work I produced provisional supports of U profile of 65 mm, 80 mm, with the angle of 40 mm to 100 mm, H profile of 100 mm, 120 mm, 160 mm, 180 mm, 200 mm, and at the end of the work I had to fix the permanent ones. I mention that I worked both on the ground and the height, in different positions more or less difficult. I worked with autogenous device, with large grinder, small grinder, Biaxial device, with electric welding machine. I used lifting equipment, such as Trifor machine of 1 to 3 tons, chain hoists with 1 to 3 tons, locks in tight places where the crane could not be used. After completion of the work we performed tests of pressure with softened water. In case of losses, we remedied them. In the next period I was sent to another power plant in Termoli area where I performed the same type of work. Also with this company I worked in a metal workshop where I produced metal pillars made of H, U profiles of 300 mm, I mounted their bed plates of 30 mm, I performed drilling, cutting with electric saws and oxy-acetylene flame device, I produced rectangular and round pipe railings. After that I worked at a cement plant in Arquata Scrivia. Here we installed the metal structure: metal pillars, metal beams, corner bracings, metal railings, metal gratings, access stairs, walkways. I mounted large pipelines with a diameter of 2000 mm and 900 mm diameter curves, I connected them to the gas emanation chimney. After this period I was sent to "Mario Savioli" chemical plant in Mantova, where I worked on repairs. I replaced pipe segments from 8" to 18" butterfly valves of 6 ", 8", 10 ", 14" , slide valves of 1/2 ", 3/4", 1 ", 2", neck, flat flanges, elbows of 45 degrees, 90 degrees, everything that was damaged. And here I worked at height and in difficult positions.
In the first seven years I worked at the heating installation from the plant platform. I replaced the defective taps in the system, which served to vent or drain the installation, I replaced the valve seals, taps, flanges that were damaged, repaired pumps that were installed for circulating water in the system or those mounted on the route, replaced the pipe segments or made changes as required by the procedure. For these works I used the oxy-acetylene flame device, electric welding machine and grinder. I used the following equipment and materials: ball valves, globe valves, taps with butterfly valves from 1/2" to 2", direction valves of 4 ", 6", elbows of 90, 45 degrees, equal Ts, Ts reduced from 1" to 12", control valves from 4 "to 18". Starting from 01.05.1997 to 30.10.1997 I have been detached to Kuwait to work in a petrochemical plant. There I took part in various works, including, steel structure assembly: steel beams, railings, access stairs, metal lattices, bracings, walkways, and joinings were made by welding or by screws. Equipment and materials used: gussets made of sheet of 5 to 8 mm, U, H, I profiles with sizes between 80 and 200 mm, angle of 30 to 80 mm, band from 20 to 60 mm, thickness of 3-5 mm. All these materials were made of steel. For this work I used large grinder, small grinder, oxy-acetylene flame machine, electric welding machine, wrenches, and ring and barrel keys. After completion of the metal structure I had to mount pipes and equipment made of stainless steel and carbon. First I went in warehouse where I had to choose positions, valves, fittings, flanges. I prepared them, then I assembled them in conformity with the execution plan. Equipment used: closing-opening taps with steel valves of 15-250 mm, pn 16 bar, butterfly valves lever operated, gear and rod, safety valves of stainless steel, cast iron and steel, sliding valves of 50 - 500 mm, assembly compensator, control valves with electric and pneumatic control Class 150, 300, 600, low branches, low Ts, equal Ts, weldable, size 21-600 mm, materials P 235, P 265, steel, stainless steel, concentric reducers and eccentric reducers. After this period I returned to Cernavoda nuclear power plant. Here I started working in the reactor and machine room. I performed the control of the valves in the warehouse, then I started to assemble pipes for the installation. Materials used were: steel pipe, carbon steel pipe P19, P22, of various sizes from 1" to 20", 45 degree elbows, 90 degree elbows, curves, bends, concentric and eccentric reducers, equal Ts, low Ts, valves, pneumatic valves with electric drive, butterfly valves. For these works I used large grinder, small grinder, Biaxial device. Each work is performed by a well established procedure.
At Portile de Fier hydro-electric power plant, I performed the installation of pipes to for the actuator drive. This operation began in an underground gallery and outdoor. There were eight actuators, each with two pipes (round trip). First I traced the piece, cutting it with a large grinder with cutting disk, and depending on the material, I had to gauge it. I placed the pipe on some adjustable devices for alignment, positioning it with a guide clamp. At joining I left a space of 3-4 mm throughout the circumference, controlling it to be in front on the inside and outside, then had to be welded; I performed chamfering in the position, in narrow spaces, as needed. All these operations were performed in the gallery, then started the installation in conformity with the layout: first I fixed pipes on the wall, on the carriers made of U profile of 80 mm. From these pipes I made the connection vertically to the actuator. Service valves were mounted in the pump room. Scaffolds were mounted around actuators. I raised the pipes by means of Trifor, chain hoists, yales of 1-3 tons. When installing a valve, I made the connection by its body and mounted the flanges in the two holes, with a controlling level. These operations were executed at height. After completion of work I performed pressure tests at 200 bar. This was a hydraulic oil installation. After completing this work I was assigned to the site, to make some repairs to the turbine protection gratings: I mounted four legs made of I profile of 200 mm provided with a base plate steel of 8 mm on each end grating, making very accurate measurements because they are were mounted superimposed. I traced and cut pieces of all shapes made of laminated plate of 10mm, 20 mm, 30 mm, side angle of 40 mm - 50 mm made of U profile of 80 mm - 100 mm, with autogenous device, in conformity with the layout, then I made holes, being used for the manufacture of pipe supports and round-shaped plates were used as blinds.
I was part of a team of 8 workers, being divided by 2 workers in each sector of work. I mounted pipes of different sizes in warehouses for distribution of hot and cold water, air, steam, oxygen, gas and district heating networks on pipe rack, making the connection to each house, as necessary. I mention that I work in conformity with an execution plan developed by the designer. The pipes were prepared both ground and the position: I performed operation of measuring, marking, cutting, gauging, cutting them with the grinder or oxy-acetylene flame device, after which they were gauged on the outside with the grinder, and on the inside I cleaned them with Biaxial device; during these operations I placed the pipes on adjustable devices, then I positioned the pipe using a guide clamp, I aligned it throughout the entire length, in the joining I left a space of 3-4 mm to be ready for welding. For every connection from the main column I had to mount the service valves, at the flange-flange or flange-tap, flange connection, I had to tighten the screws crosswise, uniformly, and seal them to be well positioned on the mirror of flange or valve, after it was cleaned and checked. When I had to install a flat pipe flange, I inserted the pipe to the middle of the flange, level controlled it horizontally and vertically, aftuire it in four points and welded it both inside and outside. In the installation I used the following equipment: sliding valves, weldable elbows to 45 degrees, 90 degrees, from 1/2" to 18", weldable Ts, reducers from 8 "- 4", from 6 to 2 " etc.., depending on the situation, butterfly valves of different sizes, carbon steel pipe; pipes are of the following sizes: 32, 40, 76, 89, 108, 114, 133, 168, 219, 300. When I worked with galvanized pipe, I made the joining by tapping, using fittings: nipples, sockets from 3/8 "- 4", reducers with internal and external thread from1"-3 / 4", from 2"-1 / 2" elbows of 90 degrees, 45 degrees with internal-external thread from 1/2 "-4"; for these pipes we produced supports made of different materials, e.g. U profile of 65 mm, 80 mm, 100 mm, H, I, profiles, angle of 40-50 mm, which were temporary until the permanent installation. Pipes had to be aligned perfectly with each other.
