SB 167 pipes (ASTM B167) are high-nickel alloy seamless tubes and pipes, primarily Inconel (like Inconel 600, 601), known for exceptional strength, corrosion resistance (especially to dry chlorine/HCl), and performance in extreme temperatures, making them ideal for chemical processing, high-temp systems, and demanding industrial uses where stainless steel fails. They offer immunity to chloride stress corrosion cracking and come in various schedules and sizes.
Key Characteristics
- Material: Nickel-Chromium Alloys (Inconel, etc.).
- Type: Seamless (most common) or ERW.
- Properties: High nickel/chromium content provides excellent resistance to reducing/oxidizing conditions, high temps, and chloride stress corrosion cracking.
- Applications: Chemical handling, high-temperature environments, aerospace, petrochemicals, cryogenic settings.
- Grades: Includes UNS N06600 (Inconel 600), N06601 (Inconel 601), N06625, N08800, etc..
- Forms: Pipes, tubes, available in various schedules (thicknesses) and lengths.

Why Use Them?
- Superior Corrosion: Outperforms stainless steel in harsh chemical environments like dry chlorine or hydrogen chloride.
- Temperature Versatility: Works from cryogenic to very high temperatures (up to ~650°C for some environments).
- Stress Corrosion Cracking (SCC) Immunity: A primary solution for SCC issues common with other alloys.
