FAQ – ASME SA192 High Pressure Boiler Tubes
Q1: What is the difference between ASME SA192 and ASME SA179?
A: SA192 is designed for high pressure boiler service with heavier wall thickness capability (up to 15mm) and larger OD (up to 7″). SA179 is for heat exchangers and condensers (thin wall, max 3″ OD).
Q2: What is the maximum operating temperature for SA192?
A: Typically up to 450°C (850°F). For higher temperatures, consider ASME SA213 alloy grades.
Q3: Is SA192 suitable for superheater service?
A: Yes. SA192 can be used for superheater tubes at moderate temperatures (up to 450°C). For higher temperature superheaters, use SA213 T11 or T22.
Q4: What is the difference between SA192 and SA210?
A: SA210 (Grade A-1/Grade C) is medium carbon steel with higher strength (≥415/485 MPa tensile) for more demanding boiler service. SA192 is standard strength (≥325 MPa).
Q5: Does SA192 require impact testing?
A: Generally no for standard service. For low temperature or specific applications, consultation with the ASME Code is required.
Q6: Can SA192 be welded?
A: Yes. SA192 has excellent weldability. Standard welding procedures apply. No preheat required for thin sections.
Q7: Do you provide third-party inspection?
A: Yes. SGS, BV, TUV, DNV, or any customer-specified agency.
Q8: Do you offer free samples?
A: 30cm sample available upon request. Shipping fee applies.
