«EVRAZENERGOPROJECT» LLC suppliers pipeline components, parts and assembly units for various generating units of thermal power plants. Such pipelines are intended for transporting steam, hot water and other process media (such as lubricating oil, fuel oil, gaseous mixtures, etc). Thermal power plant pipelines can be divided into station pipelines and turbine pipelines. Depending on the operating parameters (pressure and temperature) of the transported medium, pipelines are divided into two major groups: high pressure and low pressure. Depending on the intended use of a pipeline, it can be made from steel of the following main grades: steel 20, 15GS, 17G1S, 09G2S, 10G2, 12Kh1MF, 15Kh1M 1F, 10Kh9MFB-Sh, etc.

The main ranges of products offered by our company for thermal power plant pipelines include:

• Bend pipes and short radius bend pipes;
• Pressed, forged welded and drawn bends (elbows);
• Pressed, forged and welded tees and tees with extended inlets;
• Nipple joints and manifolds;
• Pressed, welded and forged welded reducers;
• Flat blinds and pressed elliptic bottoms;
• Welded and flanged flow meters;
• Various flanges and fasteners;

All parts and assembly units are manufactures both according to applicable standards and according to in-house standard and original drawings.
