Carbon steel tubes
Zhangjiagang Huayou Tubular Co., Ltd supplies carbon steel tubes manufactured to ASTM A106 Grade B and ASTM A179 standards, both widely recognized for high-temperature service in boilers, superheaters, and heat exchangers. ASTM A106 Grade B is a seamless carbon steel pipe specification for high-pressure and high-temperature applications, while ASTM A179 covers minimum-wall-thickness, seamless cold-drawn low-carbon steel tubes for tubular heat exchangers and condensers. The supplier’s tubes are designed for durability in demanding environments such as oil and gas processing and power generation.
The seamless manufacturing process ensures uniformity in wall thickness and mechanical properties, which is critical for maintaining pressure integrity in service. ASTM A106 Grade B typically includes a carbon content of 0.30% max and a tensile strength of 415 MPa min, providing a balance of strength and weldability. ASTM A179 tubes, with lower carbon content (0.06 - 0.18%), offer superior formability and are often used in heat transfer applications where thermal conductivity is a priority.
These tubes are sourced globally for large-scale industrial projects, where their cost efficiency and reliability make them a preferred choice. Buyers should specify outer diameter, wall thickness, and length requirements, as these directly influence the tubes’ pressure ratings and compatibility with existing systems. The supplier, based in Zhangjiagang, Jiangsu Province, can facilitate exports via nearby ports such as Shanghai, with packaging and incoterms negotiated per order.
| Material Standard | ASTM A106 Grade B / ASTM A179 |
| Manufacturing Process | Seamless, cold-drawn |
| Typical Carbon Content (ASTM A106 Grade B) | ≤ 0.30% |
| Typical Tensile Strength (ASTM A106 Grade B) | ≥ 415 MPa |
| Typical Yield Strength (ASTM A106 Grade B) | ≥ 240 MPa |
| Typical Carbon Content (ASTM A179) | 0.06 - 0.18% |
| Typical Outer Diameter Range | 10.3 mm to 114.3 mm (standard for ASTM A106/A179) |
| Typical Wall Thickness Range | 1.24 mm to 12.7 mm (standard for heat exchanger tubes) |
| Surface Finish | Cold-drawn, smooth finish (standard for ASTM A179) |
| Testing Standard | Hydrostatic test per ASTM A530 (typical for seamless tubes) |
Zhangjiagang Huayou Tubular Co., Ltd is located in Zhangjiagang, Jiangsu Province, a city known for its steel tube manufacturing industry. The company holds an imported trust tier, indicating it has been verified in international trade databases, though its response metrics are not currently available. The supplier focuses on seamless carbon steel tubes for industrial applications, particularly in heat transfer and pressure systems.
The profile does not specify production capacity, certifications, or export history, so buyers should directly confirm compliance with additional standards such as ASME Section II or EN 10216 if required. Zhangjiagang’s proximity to Shanghai port facilitates efficient logistics for international shipments. All trade terms, including MOQ, packaging, and incoterms, must be clarified with the supplier prior to ordering.
Our carbon steel tubes are manufactured to ASTM A106 and ASTM A179 standards, making them ideal for high-temperature and high-pressure applications in oil and gas, petrochemical, and power generation industries. These seamless tubes offer excellent strength and corrosion resistance while maintaining cost efficiency for large-scale industrial projects. Widely sourced globally, carbon steel tubes are a staple in international steel trade, with competitive pricing driven by raw material costs and manufacturing specifications.

Sourcing Carbon steel tubes from Zhangjiagang Huayou Tubular Co., Ltd - China Import Guide
Prior to ordering, confirm that the tubes meet your project’s specific standards and service conditions by reviewing the mill certificates and compliance documentation. If your application requires additional certifications, such as ASME or PED, request written confirmation from the supplier. For critical applications, consider arranging a third-party inspection to verify dimensions, material properties, and testing results.
Discuss logistics details with the supplier, including packaging, labeling, and incoterms. Zhangjiagang’s location near Shanghai port offers efficient access to global shipping routes, but buyers should confirm whether FOB, CFR, or CIF terms are available. Lead times may depend on production schedules and raw material availability, so obtain a written delivery timeline before finalizing the order.
Upon receipt, inspect the tubes for visual defects, dimensional accuracy, and compliance with the ordered specifications. Verify that all required documentation, including packing lists, commercial invoices, and certificates of origin, is complete and accurate. For large orders, consider conducting a pre-shipment inspection to ensure the tubes meet your quality standards before they leave the supplier’s facility.
