製品の説明
Custom High Temperature Flange Bolts for Steam Turbine
Our turbine flange bolts are critical fasteners designed for high-pressure cylinder flanges, main steam pipeline flanges, and valve body connections of thermal power units. Custom-made from high-temperature alloy steel such as 25Cr2MoVA, 42CrMo, F91, and F92, these bolts withstand long-term high temperature, high pressure, and alternating loads without loosening or creep deformation.
Core Advantages
Full Drawing Customization
Custom length, thread diameter, hexagon head, stud bolt with two nuts, and tensile strength grade according to turbine drawings. Interchangeable spare parts for all brand steam turbines.
High-Temp Anti-Creep Material
Alloy steel forging with integral heat treatment provides excellent tensile yield strength, anti-fatigue, and anti-oxidation performance under 540℃~620℃ ultra-supercritical working conditions.
Precision Thread Machining
Fine rolling thread with high matching accuracy ensures uniform stress distribution. Optional black oxide, nitriding, or zinc plating anti-rust treatments available.
Strict Quality Inspection
Comprehensive testing including raw material spectrum analysis, mechanical tensile testing, ultrasonic flaw detection for forging defects, and full dimension inspection. Complete MTC and inspection reports provided for power plant acceptance.
Applications
Steam turbine high/medium pressure cylinder flange, main stop valve & control valve flange, high-pressure steam pipeline, boiler header, and power station equipment fastening.
