1. Q: Name a standard for welded and seamless carbon steel pipe for low-temperature service (down to -50°F).
A: ASTM A333 covers seamless and welded steel pipe for low-temperature service. Common grades are Grade 1 (-50°F), Grade 6 (-50°F), and Grade 3 (-150°F, but this is a nickel alloy steel).
2. Q: What is the most common grade in ASTM A333 for low-temperature carbon steel piping?
A: ASTM A333 Grade 6 (impact tested to -50°F). It is a killed, fine-grain, carbon-manganese-silicon steel.
3. Q: For high-yield-strength, cold-formed welded structural tubing, what is an ASTM grade?
A: ASTM A500 Grade D (Round: Min Yield 58 ksi, Rectangular: Min Yield 62 ksi).
4. Q: What is a common standard and grade for continuous galvanized steel pipe (tube) for fencing and handrails?
A: ASTM A53 Grade B, Type E (ERW) and then galvanized per ASTM A153, or ASTM A120 (galvanized).
5. Q: Which standard and grade are typical for seamless carbon steel pipe used in the food and beverage industry?
A: ASTM A106 Grade B or ASTM A53 Grade B, often with a special internal finish or coating.
