Core Application Scenarios

1. Power Plant Boiler System

• Overheater and ReheaterWithstanding steam temperatures above 600°C, it requires exceptional creep resistance (such as T91/T92 alloy pipes, with a tensile strength of over 100MPa at 625°C).

• Main Steam PipelineSupplies supercritical steam (pressure ≥ 25 MPa) and utilizes P92 alloy steel (tensile strength ≥ 620 MPa) to ensure long-term safe operation.

• Thermal Insulation EconomizerOptimized thermal efficiency in the low temperature range (≤450°C) is achieved using commonly employed 20G carbon steel pipes or 15CrMoG alloy pipes.

• Chemical VesselsThe reforming tubes in the synthetic ammonia unit require resistance to H₂S/CO corrosion, utilizing 12Cr2MoWVTiB (improving corrosion resistance by 30%).

• Refining Cracking FurnaceUnder conditions of 550°C and 8MPa, the 12Cr1MoVG alloy pipe, after being treated with normalizing plus tempering, achieves a tissue stability of 100,000 hours.
