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.

Bend is a crucial pipe fitting used to change the direction of flow in a piping system. It allows for smooth transitions between sections of pipe, accommodating layout constraints, avoiding obstacles, and optimizing flow paths. Bends are designed to maintain the fluid's velocity and minimize pressure loss while providing the necessary angle of deviation. They are commonly used in various industries, including oil and gas, petrochemicals, water supply, and HVAC systems.
