Product Description
GOST TU 14-3-460 Low Carbon Alloy Steel Tube For High Pressure Boiler
GOST TU 14-3-460 low carbon alloy steel tubes are seamless boiler and steam-pipeline tubes designed for high-pressure and high-temperature service in power boilers, superheaters, reheaters, headers, and steam pipelines. The specification covers carbon, low-alloy, and heat-resistant alloy steel tubes with standardized high-temperature properties for steam boilers and pipelines, including high and supercritical steam parameters.

Our Advantages
| Buyer Concern | Our Solution |
|---|---|
| Grade selection for temperature and pressure | We help match 20-PV, 15GS, 15CrMo, 12Cr1MoV, or 15H1M1F according to boiler zone, steam temperature, wall thickness, and creep-resistance requirement. |
| Dimensional risk during boiler assembly | We control OD, wall thickness, ovality, straightness, and cut length according to TU 14-3-460 tolerance logic, with additional agreement available for tube-bank fabrication. |
| Material traceability and inspection reliability | Each batch can be supplied with heat number tracking, chemical analysis, mechanical test report, heat-treatment record, NDT record, and EN 10204 3.1-type inspection documentation when required. |
