Reliable Carbon Steel Pipe Systems | ISO-Certified & Corrosion-Resistant

Product Overview

Our carbon steel pipe systems are engineered for industrial durability, combining ISO-certified manufacturing with advanced anti-corrosion technologies. Designed to address challenges like carbon buildup in exhaust pipe scenarios, these pipes are ideal for high-pressure oil/gas pipelines, structural frameworks, and automotive exhaust systems. Compatible with standard carbon steel pipe sizes and engineered to outperform alternatives like carbon fiber exhaust pipe in cost-effectiveness and heat resistance, our solutions ensure longevity and operational safety.

Technical Specifications

Key specifications are summarized below:

Mechanical Properties

Tensile Strength

Our carbon steel pipe delivers tensile strengths ranging from 320–550 MPa, depending on the grade (e.g., ST37 for general use, ST52 for high-stress environments). This ensures resistance to deformation under extreme pressures, making it suitable for oil pipelines and industrial exhaust systems prone to carbon buildup in exhaust pipe scenarios. The seamless design eliminates weld seams, reducing weak points and enhancing structural integrity.

Bend Strength

ST52-grade pipes achieve bend strengths up to 360 MPa, with cold-rolled variants maintaining ±0.1mm tolerances for precision applications like automotive components. Advanced coatings like epoxy powder (30–80μm thickness) prevent internal corrosion, even in environments with chloride or sulfate exposure.

Identification & Marking

Each pipe is laser-etched with:

• Material Grade (e.g., ST52, ASTM A53 Gr.B)
• OD/Wall Thickness (e.g., 100mm x 8mm)
• Standard Compliance (e.g., DIN 2448, API 5L)
• Heat Treatment Code (e.g., +QT for quenched & tempered).

Weight Calculation

Calculate pipe weight per meter using the formula:
$\text{Weight (kg/m)}=(OD-WT)\times WT\times 0.02466$
Example: For a 100mm OD pipe with 8mm wall thickness:
$(100-8)\times 8\times 0.02466=18.12\text{kg/m}$
This formula aligns with carbon steel pipe sizes guidelines and simplifies logistics planning.

Why Choose Our Carbon Steel Pipes?

1. Corrosion Resistance

Our 3PE coating (fusion-bonded epoxy) extends service life to 50–100 years, even in chloride-rich environments. For exhaust systems, this prevents carbon buildup in exhaust pipe and reduces maintenance frequency.

2. Precision Manufacturing

Cold-drawn and seamless processes ensure ±0.1mm tolerances, critical for hydraulic systems and high-pressure pipelines.

3. Custom Solutions

Tailor dimensions (including non-standard carbon steel pipe sizes), coatings (galvanized, 3PE), and delivery states (annealed, tempered) to meet project-specific needs.

4. Global Compliance

Certified to ASTM, API, and EN standards, validated by third-party inspections (SGS, TÜV).

5. Cost Efficiency

100% recyclable material with lifecycle costs 30% lower than carbon fiber exhaust pipe alternatives.

Applications Beyond Industry

• Automotive: Replace carbon fiber exhaust pipe with heat-resistant ST52 pipes for cost-effective performance.
• Construction: Load-bearing columns with capacities up to 1,000 MPa.
• Water Systems: Epoxy-coated pipes for corrosion-free municipal supply.
