ASME SB862
ASME SB862 Titanium Welded Pipes
ASME SB862 is the standard specification for titanium and titanium alloy welded pipes intended for general corrosion resistance and elevated temperature service. Covering 33 titanium and alloy grades, SB862 pipes are widely used in heat exchangers, condensers, chemical process systems, power generation, and marine environments where reliability and longevity are critical.
What Is ASME SB862?
ASME SB862 is the ASME-adopted version of ASTM B862, making it fully compliant with the ASME Boiler & Pressure Vessel Code.
It specifies requirements for titanium welded pipes including material grades, chemical composition, and dimensional tolerances.
Manufacturing methods: Welded from annealed flat-rolled titanium.
Heat treatment and finishing options covered within the standard.
Mechanical properties & testing: Tensile, yield, elongation, hydrostatic, and NDT.
Marking & certification: MTC EN 10204 3.1/3.2 available with full traceability.
Searching for a trusted ASME SB 862 supplier? We provide titanium welded pipes ready for critical industrial applications.
Key Advantages of ASME SB862 Titanium Pipes
Outstanding corrosion resistance in seawater, brine, and aggressive chemical media.
High strength-to-weight ratio — ideal for reducing system weight without compromising safety.
Excellent heat performance up to 400–450°C in condensers and heat exchangers.
Reliable weld integrity: GTAW/TIG welded and may be cold-worked for microstructure refinement.
Lower lifecycle cost through longer service life and minimal maintenance.
Grades Covered Under ASME SB862
| Category | Grades | Typical Use / Notes |
|---|---|---|
| Commercially Pure Titanium | Grade 1, Grade 2, Grade 2H, Grade 3 | Excellent corrosion resistance for general industrial & marine service |
| Palladium-Enhanced | Grade 7, 7H, 11, 16, 16H, 17, 26, 26H | Best resistance in reducing acids, chloride brines, and harsh chemical media |
| Alpha-Beta Alloys | Grade 5 (Ti-6Al-4V), 23 (ELI), 24, 25, 29, 35 | High-strength structural & aerospace grade alloys |
| Other Specialty Alloys | Grade 9, 12, 13, 14, 15, 18, 19, 20, 21, 28, 33, 34, 37, 38, 39 | Selected for strength, weldability, or elevated-temperature corrosion resistance |
Grades are selected based on service environment — seawater, acids, or high-strength industrial needs.
