FAQS on 3.5 steel pipe

Carbon Steel Seamless Steel Pipe Specifications

Q: What are the key specifications of 3.5-inch carbon steel seamless pipes?

A: 3.5-inch carbon steel seamless pipes typically have an outer diameter of 88.9 mm, wall thickness ranging from 3.68 mm to 12.7 mm, and comply with ASTM A106/A53 standards for high-temperature applications.

Price Comparison for Large-Diameter Pipes

Q: How does the 8-inch steel pipe price compare to 3.5-inch pipes?

A: 8-inch steel pipes generally cost 30-50% more than 3.5-inch pipes due to increased material usage, with current market prices averaging $800-$1,200 per ton depending on wall thickness and coating.

Compatibility of Pipe Fittings

Q: Are standard pipe fittings compatible with 3.5 steel pipe dimensions?

A: Yes, 3.5-inch pipes use NPS 3.5 fittings with 88.9 mm OD, but verification of pressure ratings and thread standards (NPT or BSP) is essential for proper sealing.

Material Advantages in Construction

Q: Why choose carbon steel seamless pipes for industrial applications?

A: Carbon steel seamless pipes offer superior strength, corrosion resistance, and leak-proof performance, making them ideal for high-pressure systems in oil/gas and chemical industries.

Ordering Considerations for Bulk Purchases

Q: What factors affect pricing when ordering 3.5 steel pipes in bulk?

A: Bulk pricing depends on material grade (A106B vs A53), surface treatment (galvanized/black), MOQ requirements (typically 20+ tons), and current raw material market fluctuations.
