Hemaokang Steel (Shandong) Co., Ltd. is proud to offer the A106 Gr.B Seamless Carbon Steel Pipe — a reliable and high-performance solution for high-temperature and high-pressure service. As a direct factory with 51–100 experienced professionals and annual export value of US$50–100 million, we combine advanced manufacturing techniques with rigorous quality control to deliver pipes that meet international standards. Our commitment goes beyond product quality: every order comes with free technical training and installation guidance, ensuring your team can handle the pipe safely and efficiently from day one.
This ASTM A106 Grade B seamless pipe is manufactured through a fully controlled hot-rolled or cold-drawn process, guaranteeing uniform wall thickness, excellent weldability, and superior mechanical strength. It is specifically designed for bending, flanging, and welding in high-temperature applications such as power plants, refineries, chemical processing, and gas distribution. With a maximum carbon content limited to 0.30% and a minimum tensile strength of 60,000 psi, it consistently performs under demanding operational conditions.
We understand that selecting the right pipe for your project is critical. Below we have summarized the key specifications and advantages of our A106 Gr.B seamless pipe:
| Property | Value |
|---|---|
| Standard | ASTM A106 / ASME SA106 |
| Grade | Gr.B (Grade B) |
| Manufacturing Method | Seamless (hot finished / cold drawn) |
| Outside Diameter | 1/2" – 24" (DN15 – DN600) |
| Wall Thickness | SCH20, SCH40, SCH80, SCH160, XS, XXS |
| Length | 5.8m – 12m or custom length |
| Surface Treatment | Black painted, oiled, varnished, or galvanized (upon request) |
| Inspection & Testing | Hydrostatic test, eddy current test, tensile test, flattening test, impact test available |
Why choose our A106 Gr.B seamless pipe? The answer lies in the details:
- Excellent high-temperature resistance: The grade B composition stabilizes mechanical properties up to 750°F (400°C), making it ideal for boiler tubes, heat exchangers, and superheater lines.
- Exceptional dimensional accuracy: Our advanced cold-drawing process ensures tight tolerances on OD and wall thickness, which simplifies installation and reduces material waste on site.
- Superior pressure-bearing capacity: Each pipe is manufactured to withstand high internal pressures, with minimum yield strength of 35,000 psi and tensile strength of 60,000 psi.
- Good weldability and formability: The low carbon content prevents cracking during welding and bending, allowing fabricators to shape the pipe without preheating in most cases.
- Long service life: The uniform microstructure and freedom from internal seams minimize corrosion and fatigue, resulting in extended operational durability.
- Custom logistics support: Our port of shipment is Qingdao, one of the busiest and most reliable ports in China, allowing fast and flexible delivery to any global destination.
We provide free technical training and installation guidance with every order. Our engineering team will share practical instructions on cutting, threading, welding, bending, pressure testing, and maintenance. This service is particularly valuable for contractors, engineers, and procurement teams who need to ensure project compliance and safety. You can rely on us as a long-term partner, not just a pipe supplier.

Frequently Asked Questions
Q1: What is the difference between A106 Gr.B and A53 Gr.B pipe?
The main difference is application. A106 Gr.B is designed for high-temperature and high-pressure service in refineries, power plants, and boiler systems. A53 Gr.B is commonly used for mechanical and low-pressure applications. Both are seamless, but A106 has stricter chemical and testing requirements for elevated temperature use.
Q2: Can this pipe be used for high-temperature steam lines?
Yes. A106 Gr.B is specifically formulated for high-temperature service. It can typically handle temperatures up to about 750°F (400°C) in continuous operation, provided wall thickness and pressure ratings are correctly selected for the project.
Q3: Do you provide custom lengths and packaging?
Yes. We offer custom lengths from 5.8m to 12m or even longer depending on production capabilities. Packaging options include bare bundles, hex bundles, or individually wrapped with protective caps, suitable for sea transport to any port.
Q4: What tests are performed on each shipment?
Each batch undergoes hydrostatic testing, dimensional inspection, visual inspection, and chemical composition analysis. Additional tests such as eddy current, ultrasonic testing, flattening, and impact tests are available upon customer request.
Q5: How does the free technical training and installation guidance work?
Once your order is confirmed, we send you detailed installation manuals, video tutorials, and a dedicated engineer who can conduct an online training session. For large orders, we can also arrange on-site technical guidance depending on your location and availability.
Q6: What is your minimum order quantity (MOQ)?
We do not enforce a high MOQ. Standard MOQ is 1 ton or 5 tons depending on size. For approved distributors, smaller trial orders are acceptable to evaluate our quality and service.
Q7: Do you supply other grades beyond A106 Gr.B?
Yes. We also supply A106 Gr.A, Gr.C, A53 Gr.B, API 5L Gr.B/X42/X52, and other carbon steel pipe grades. You can combine multiple grades and sizes in one container to reduce freight costs. Please contact us with your full requirement.
Q8: How do you ensure the chemical and mechanical properties meet the standard?
We source steel from qualified mills and verify each heat with a mill certificate. In our own testing facility, we run spectrometric analysis and tensile testing to confirm the material meets ASTM A106 Gr.B requirements. Copies of all certificates are provided with the shipping documents.
With competitive pricing, dedicated service, and a genuine commitment to quality, Hemaokang Steel (Shandong) Co., Ltd. is the right supplier for your carbon steel piping projects. Request a quote now and let us provide the pipe and the know-how your team needs.
