Industrial methods of piping installation provide centralized mechanized shop production of formed pieces and spools with observance of stream-lining. Advantages of centralized production include:
mechanization of cutting, cutoff turning, welding and other operations;
increase of labor productivity up to 30% vs. individual manufacturing of formed pieces and spools immediately at a construction site;
provision of construction projects with formed pieces and spools under the unified standards;
labor saving at installation of pipelines (welding of 50-60% welded joints in the shop).
In order to attain this goal Plant (UTEM-ZVT) was commissioned in 2018, which specializes in production of formed pieces and spools for needs of nuclear and thermal power industry, as well as enterprises of steelmaking, oil & gas, chemical and other industries.
Production capacities of the plant are located in the shops with overall area 1500 m2. The plant has modern equipment for mechanized and plasma cutting of pipes and rolled steel, bending, welding, heat treatment, shot-blast cleaning and painting of product surfaces by leading European makers: ESAB (Sweden), PROMOTECH (Poland), MEBA (Germany), COPIER (Netherlands), ATLAS COPCO (Sweden), PAVALEX (Czech Republic), DEMAG (Germany) etc.
Mandatory condition for organization of centralized production of spools is development of assembly layouts and detailed design stage . Development of documentation is conducted using modern software complexes LIRA-SAPR 2012 AutoCAD 2013, ADVANCE STEEL 2012 as per requirements of standards and technical rules and regulations in the field of manufacturing, installation of pipelines and their operation.
Process operations are automated to the maximum possible extent, that jointly with implemented, certified for compliance with requirements of ISO 9001-2015 quality management system provide consistent high quality of products. At that quality control is conducted at all production stages, starting from the moment of receipt of materials and constituent parts to dispatch of ready products.
formed pieces and spools NPP group А, В, С as per PNAE G-008-89;
formed pieces and spools of steam and hot water I-IV categories;
Formed pieces of pipelines:
elbows, reducers, tees;
flanges (DN up to 1200);
plugs: stop flange, turned, welded;
Spools (including made of austenic steels):
high pressure spools;
