Manufacturing Plant

The manufacturing plant was set up in 2014. It produces standard and unique high-tech equipment for nuclear and other industries. 

The manufacturing plant offers complete cycle of product manufacturing - from technological development of the design documentation to packing and shipping.

Total production area – 3474 m², staff – 118 persons.

The equipment is produced to the design documentation developed by the Company’s engineering design department (up to 90% of all products) and to the customer-supplied drawings.  

Quality Management System of the Manufacturing Plant is certified in compliance with ISO 9001. Quality control of the products is performed by the certified experts on each stage of the production process.

The manufacturing plant includes Engineering Service, whose team elaborates step-by-step manufacture procedure of products, chooses appropriate raw materials and components, provides CNC programming, develops and qualifies welding procedures, designs testing equipment. 

Machining workshops carries out such operations as:

• band saw cutting of rolled stock :

• water jet cutting of sheet stock :

• rolling of carbon and stainless steel sheets : 

• bending of metal sheets and tubes
• heat treatment (quenching, tempering, annealing, air-hardening)

• lathe machining :

• CNC milling :

Non-Standard Equipment Fabrication Workshop is intended for assembling units and products and preparation of auxiliary equipment and tooling for testing the ready-made products. The workshop performs :

• machine assembly
• welding
• weld dressing to meet the required roughness parameters.

Welding is applied to join the parts of various configurations. The materials can be pearlitic steels, highly-alloyed chromium martensitic and martensitic-ferritic steels, stainless austenitic steels, aluminum, and aluminum alloys. State-of-the-art welding equipment operates in:

• Tungsten inert gas welding with or without filler metal,
• Mechanized argon arc welding with consumable electrodes, and
• Shielded metal arc welding.

The Company has qualified welders certified for the national standard PNAE G-7-003-87. Five employees of the manufacturing plant have certificates for Rostechnadzor-regulated welding operations. The process planning department ensures necessary documents for the manufacturing process. In particular, the following certificates are available:

• 38 certificates of welding procedure qualification (104 procedures) as required by the conformity assessment system for the use of nuclear energy,
• 2 certificates of welding procedure qualification (7 procedures) as required by the voluntary certification system “The Eurasian Welding Certification Society”,
• 2 certificates of engineers and technicians for work management as required by the Eurasian Welding Certification Society,
• 26 welder’s certificates for welding the equipment and pipelines for nuclear power plants,
• 1 welder’s certificate for welding as required by the Eurasian Welding Certification Society.

The finishing operations area carries out :

• sandblasting 
• glass blasting
• paintwork
• fabrication of packaging.

Quality Control Department is responsible for operation checking and acceptance of the parts, components and assemblies of a product, as well as for final acceptance of the product as a whole. At every stage of the equipment fabrication following NDE methods are employed :

• visual inspection
• inspection by measurements
• dye penetrant examination
• ultrasonic flaw detection
• radiographical testing
• leak testing using gases and liquids
• optical-emission spectrometry of metals and alloys.

Ready-made non-standard equipment is subject to in-house fit-up assembling and testing. In 2020, a new 18-meter high testing workshop was constructed and commissioned. It features a 16-ton bridge crane and a dunk test tank.

Sosny R&D Company provides warranty and post-warranty service of the supplied equipment, develops technical documents for its effective use.
