Key Features & Technical Specifications
- Seamless Construction: No welded joints, reducing the risk of leakage and ensuring uniform strength throughout the pipe. Ideal for high-pressure applications.
- ASTM A179 Grade A Standard: Complies with international specifications for low-carbon steel used in heat exchangers and condensers. Provides excellent thermal conductivity and corrosion resistance.
- Schedule 40 Wall Thickness: Offers a balanced combination of strength and flow capacity, suitable for typical boiler and heat exchanger operating conditions.
- Superior Surface Finish: Available in black, varnished, or galvanized finishes to meet specific environmental and aesthetic requirements.
- Customizable Dimensions: Outer diameters from 1/4 inch to 4 inches, with lengths up to 12 meters or custom lengths upon request. Flexible to fit your design.
- Excellent Weldability and Formability: The low carbon content makes it easy to weld, bend, and fabricate without compromising structural integrity.
| Property | Value |
|---|---|
| Tensile Strength (min) | 325 MPa |
| Yield Strength (min) | 180 MPa |
| Elongation (min) | 30% |
| Hardness (max) | 72 HRB |
These properties ensure reliable performance under thermal cycling and sustained pressure. The seamless manufacturing process also eliminates weak points, extending the service life of your equipment.

Q: What is the difference between Sch40 and other schedules?
A: Schedule 40 is a standard wall thickness defined by ANSI/ASME B36.10. It provides a balance of strength and flow capacity for moderate pressure applications. For higher pressures, you may consider Sch80 or Sch160. -
Q: Can this pipe be used for high-temperature steam service?
A: Yes, ASTM A179 Grade A is designed for service temperatures up to 450°C (842°F) in typical boiler applications. However, please consult our engineering team for specific temperature and pressure ratings. -
Q: Do you offer custom lengths or diameters?
A: Absolutely. We can produce pipes with outer diameters from 1/4 inch to 4 inches and lengths up to 12 meters, or any custom length as per your requirements. Just let us know your specifications. -
Q: What surface treatments are available?
A: Standard options include black (as-rolled), varnished, or galvanized coating. For special environments, we can also supply with anti-corrosion coatings like FBE or 3LPE upon request. -
Q: How do you ensure the quality of the pipes?
A: We follow ISO9001 quality management system. Each pipe is tested for mechanical properties, dimensions, and hydrostatic pressure. We also provide mill test certificates (MTC) with every shipment. -
Q: What is the typical lead time for orders?
A: For standard sizes, lead time is 15–25 days after order confirmation. Custom orders may take 30–45 days. We work closely with shipping lines to ensure timely delivery from Qingdao Port. -
