In April, 11th, the plant “Petrozavodskmash” held a topping-out ceremony: the new sector of production and assembly of steam-generator shells for nuclear power plants has been opened. It’s just the first stage of the program aimed at fully-fledged production of all reactor equipment for nuclear power plants.Â
Panorama of the plant construction.
The history of this production that occupies 67 hectares area is dated back the 1960s. The starting point of the plant construction was the statement of the government aimed at the liquidation of pulp and paper industry lagging and development of Russian mechanical engineering that would provide the industry needs.Â Creation of this plant in Petrozavodsk became the first step of the program.
They built heavy industrial equipment including the firstÂ in the USSR chain grinder with mass heavier than 120 tons for pulp production.
Petrozavodsk produced rollers of all types for paper making machines. Later it started to produce the machines themselves.
Giant machines intended for production and drying of paper and cardboard were delivered to the largest pulp and paper enterprises of the USSR.
Simultaneously with the development of the paper industry, the chemical sphere was rapidly developing too. In 1976 the plant put into operation a unique complex of chemical apparatus shops.
In 1978 the plant dispatched from the own special moorage 5 fully assembled distillation columns to Tobolsk. The world had no analogs of them, the columns were 100 m long and weighed 600 t each.
The range of the plant products was raising. They applied new technologies.
“Petrozavodskmash” was the first to manufacture equipment for multilayer cold-corrugated board that was used in production of carton.
The monument is made of a giant roller of a paper making machine.
“Produce a pass!”
A little museum preserves materials about the rich history of the plant.

It’s not just a cap!
Everyone should put it on for safety here
In 2010 the foundry made 5500 rollers and cylinders for paper making machines, mainly for foreign partners.
They also produce shipping packaging sets from cast iron with spheroidal graphite for storage and transportation of waste nuclear fuel.
They found various beds, stands, tubing adaptor flanges, reactor details, production tools for nuclear power plants reactors.
All these stuff is heavy so it’s trasported on trolleys with lifting capacity 100 tons and more.
Future workpiece for some detail is cooling down
Moulding boxes to the right
The grand set of used sand regeneration provided by an English company.
They have equipment for magnetic separation, vibrating ragging, tarry duster removal, cooling mixture and also a pneumatic line for sand transportation. Thanks to this equipment sand waste decreased for 90% i.e. 15 000 tons of sand a year.
A new powerful 40-tonned mixer and a vibrating table.
Sand on the floor is used for easy removal of spilled metal.
A part of the monument of a composer A. Glazunov founded at the plant.
A monument to law enforcement officials who died during discharge of duty.
Flowoff – a special element of a casting mould that serves for gas removal from the mould capacity during its filling.
Excess of mold material is removed from workpieces.
Machine assembly department.
Japanese high performance milling machining centre is the main novelty in the department.
The department looked in a different way just recently. December 2011 – April 2012
The machine is Japanese and works automatically though it requires control of a specialist. Such specialists earn 2000 USD a month.
Service information on the display
Last year the enterprise started its own reinforcing production. These are the first samples of wedge gate valves produced here. They are widely used by nuclear power plants.
Machines for lathing and grinding
Diameter of workpieces may be up to 2,5m, be up to 13 m long.
machines… Such machines are used for mechanical treatment of large capacity box-type workpieces with dimensions up to 4,5×4,5x12m and mass up to 80 t.
Processing accuracy for hole location and surfaces is 0,05 mm, for hole accuracy – 0,01 mm.
There is a great variety of machines here
Processing of large details.
Mass of the processed details may vary from 0,1 to 100 000 kg.
