(1 3 8 steel pipe)
The 1 3 8 steel pipe
, a staple in piping systems, combines dimensional precision with high-pressure resistance. Designed for industries ranging from oil and gas to construction, its nominal size (1.375-inch outer diameter) balances flow capacity and structural integrity. Over 68% of industrial projects in 2023 utilized this size due to its compatibility with standard fittings. ASTM A106 and API 5L certifications ensure compliance with safety and durability benchmarks.
Carbon steel seamless steel pipes eliminate weld weaknesses, achieving 15-20% higher burst pressure ratings compared to welded alternatives. Key properties include:
Hydrostatic testing at 30 MPa guarantees leak-free performance, critical for chemical processing plants.
| Manufacturer | Price Range (8") | Lead Time | Certifications |
|---|---|---|---|
| Company A | $280-$320/ton | 4-6 weeks | ISO 9001, PED |
| Company B | $310-$345/ton | 3-5 weeks | ASME B16.25 |
| Company C | $265-$305/ton | 6-8 weeks | API 5CT |
Current 8 inch steel pipe prices fluctuate between $265 and $345 per ton, influenced by raw material costs and anti-corrosion treatments. Bulk orders (500+ tons) typically secure 8-12% discounts. Recent carbon steel price trends show a 4.7% quarterly decrease, making Q3 2024 ideal for procurement.
Tailored services address specific project needs:
Case study: A refinery saved 14% on installation costs using pre-insulated 1 3 8 pipes with integrated temperature sensors.
In the XYZ Pipeline Project (2023), carbon steel seamless steel pipes demonstrated:
The 1 3 8 steel pipe remains unmatched in balancing cost, durability, and adaptability. With 92% customer retention rates among top suppliers, its optimized weight-to-strength ratio (0.28 kg/m per MPa) continues to drive adoption in LNG terminals and wastewater treatment facilities globally.
(1 3 8 steel pipe)
A: The 1 3/8 steel pipe typically refers to a 1.375-inch outer diameter pipe, commonly available in Schedule 40 or 80 carbon steel seamless variants. Wall thickness ranges between 0.133" to 0.200" depending on schedule. These pipes are used in low-pressure plumbing and mechanical systems.
A: Carbon steel seamless pipes lack weld seams, offering superior strength and pressure resistance compared to welded alternatives. They're manufactured through extrusion processes, making them ideal for high-temperature/pressure applications like oil and gas pipelines.
A: 8-inch steel pipes use ANSI B16.5 flanges, butt-weld elbows (45°/90°), and reducers. Common materials include carbon steel to match pipe composition. Threaded fittings aren't recommended for this size due to pressure limitations.
A: Key price drivers include raw material costs (iron ore/coal), manufacturing process (seamless vs ERW), wall thickness (Schedule 40 to XXH), and global demand. As of 2023, 8-inch carbon steel pipes average $800-$1,200 per metric ton FOB.
A: Authorized distributors like Metal One Corporation or Tenaris offer ASTM A106/A53-certified pipes. Always verify mill test certificates and request third-party inspection for critical applications. Online platforms like Alibaba also list suppliers with MOQs from 5 tons.
