FAQS on 15mo3 pipe

Q: What are the key characteristics of 15Mo3 pipe material?

A: 15Mo3 pipe is a low-alloy steel with 0.3% molybdenum content, offering enhanced high-temperature strength and creep resistance. It is commonly used in power plants and boiler systems for steam transportation. Its operating temperature range typically spans 450-550°C.

Q: How does a carrier pipe differ from a casing pipe in pipeline systems?

A: The carrier pipe transports fluids/gases, while the casing pipe acts as protective sleeve against external loads and corrosion. Casing pipes are typically larger in diameter to encase carrier pipes. This dual-pipe system is critical for hazardous or high-pressure media transportation.

Q: What standards apply to pipe-to-pipe welding for 15Mo3 pipelines?

A: 15Mo3 pipe welding follows ASME B31.1/B31.3 standards for power and process piping. Preheating (200-250°C) and post-weld heat treatment (PWHT) at 680-700°C are mandatory. Weld procedures must use matching electrodes like E8018-B2 to maintain material properties.

Q: Can 15Mo3 pipes be directly welded to carbon steel pipes?

A: Yes, but with specific precautions. Transition joints or buttering layers using nickel-based alloys are recommended. Welding must follow EN ISO 15614-1 procedure qualification standards. Post-weld heat treatment is critical to address differential thermal expansion properties.

Q: What inspection methods verify 15Mo3 pipe weld integrity?

A: Non-destructive testing (NDT) methods include radiography (RT) and ultrasonic testing (UT) for defect detection. Hardness testing ensures proper heat treatment (max 250 HV10). Visual inspection and pressure testing validate weld geometry and leak-tightness respectively.
