Supercritical boilers in thermal power plants: used for superheater/reheater pipes in high-temperature and high-pressure environments (≤500℃, ≤30 MPa), resistant to sulfur-containing flue gas and steam oxidation corrosion.
Chemical industry waste heat boiler: In the cracking gas (containing H₂S, Cl⁻) recovery system, avoid stress corrosion cracking (SCC).
(2) Marine platform steam injection boiler
Steam pipeline for heavy oil thermal recovery: Applicable to wet steam environment containing CO₂/H₂S (temperature 200-350℃), meeting NACE MR0175 requirements for resistance to sulfide stress corrosion.
Seawater desalination multi-effect evaporators: Long-term service under high-temperature and high-salt fog conditions (Cl⁻ concentration > 10,000 ppm).
(3) Nuclear power plant secondary circuit system
Feedwater heater tube bundle: Resistant to the synergistic corrosion of trace Cl⁻ (<0.1 ppm) and ammonia (pH 9.5 - 10.5) in the secondary circuit.
(4) Marine power boilers
Marine exhaust gas boilers: Treat diesel engine exhaust gas containing SOₓ to prevent low-temperature sulfuric acid dew point corrosion.
ASME SB163 MONEL 400 Boiler Tube FAQ
1. What is ASME SB163?
ASME SB163 is a specification that covers seamless and welded nickel-copper alloy (MONEL 400) tubes for use in high-temperature and high-pressure environments, particularly in applications where corrosion resistance is critical.
2. What are the key properties of MONEL 400?
MONEL 400 exhibits excellent corrosion resistance, particularly in seawater and acidic environments. It also has good mechanical properties at both elevated and cryogenic temperatures.
3. How does MONEL 400 perform in high temperatures?
MONEL 400 maintains its strength and corrosion resistance at elevated temperatures, making it suitable for high-temperature applications like steam generators and superheaters.
4. Can MONEL 400 be welded?
Yes, MONEL 400 can be welded using appropriate welding techniques. However, it is important to follow specific procedures to ensure the integrity of the weld.
5. What are the considerations for maintenance and inspection?
Regular inspection for corrosion or wear is essential, especially in harsh environments. Maintenance practices should include monitoring for any signs of degradation.
6. How does the cost of MONEL 400 compare to other materials?
MONEL 400 is generally more expensive than standard carbon steels or stainless steels due to its nickel content and specialized properties, but its longevity and performance can justify the cost in critical applications.
7. Are there alternatives to MONEL 400?
While there are alternatives like stainless steel alloys, the choice depends on the specific environmental conditions and performance requirements. MONEL 400 is particularly favored in highly corrosive environments.
