Products Description
P12 Alloy Steel Pipe is a Cr-Mo alloy steel seamless pipe that meets the ASTM A335 standard. Its main component is 1Cr1/2Mo, and it has excellent high-temperature oxidation resistance and long-lasting strength. This product is widely used in high-temperature and high-pressure pipeline systems such as petroleum, chemical industry, and power stations, and is one of the key pipes in pressure-bearing equipment.
Advantages
Strict heat treatment
The steel pipe is treated with normalizing + tempering to form a uniform and delicate pearlite + ferrite structure, which greatly improves the material's organizational stability and fatigue resistance.
High corrosion resistance
The alloy elements added to P12 steel can form a dense oxide film on the inner surface of the pipe, effectively resisting the erosion of industrial corrosive media such as high-temperature steam, sulfur dioxide, and nitrogen oxides, and extending the service life.
High dimensional stability
The steel pipe adopts hot-rolled and cold-drawn seamless pipe processes to ensure uniform wall thickness, low ovality, and small dimensional tolerance.
Applications
Power industry: high-temperature superheater, reheater pipeline, main steam pipeline
Petrochemical: high-temperature heat exchanger tubes in oil refining equipment, heat medium transportation system
Boiler manufacturing: medium and high pressure boilers, economizers, header connection pipes
Industrial heat treatment equipment: hot air pipes, heat conduction pipes, heat reaction furnace piping
