0As a leading china a106 pipe supplier. We specialize in providing high-performance ASTM A106 pipes, designed for critical applications involving high temperatures and pressures.
Our core product, the A106 Seamless Pipe, is manufactured through hot-rolled or cold-drawn seamless processes, ensuring no weld seam and a uniform microstructure. This makes it an ideal A106 seamless pressure pipe for power plants, refineries, boilers, and petrochemical facilities.
We primarily supply A106 Grade B Seamless Pipe—the most common grade—as well as Grades A and C. All our A106 Carbon Steel Pipe strictly complies with ASTM A106/ASME SA106 standards, ensuring superior heat resistance and mechanical integrity. Whether you need standard sizes or custom dimensions, our A106 Seamless Steel Pipe delivers reliable performance.

Tensile Strength (min): 485 MPa (70,000 psi)
Yield Strength (min): 275 MPa (40,000 psi)
Applications: Heavy-duty industrial piping, high-pressure applications.
To help engineering teams select the right material for high-temperature service, here is the detailed comparison between ASTM A106 Grade B and Grade C according to ASME/ASTM standards:
| Specifications | ASTM A106 Grade B (Gr.B) | ASTM A106 Grade C (Gr.C) |
|---|---|---|
| Carbon (C) Max % | 0.30% | 0.35% |
| Manganese (Mn) % | 0.29 – 1.06% | 0.29 – 1.06% |
| Silicon (Si) Min % | 0.10% | 0.10% |
| Tensile Strength Min | 415 MPa (60,000 psi) | 485 MPa (70,000 psi) |
| Yield Strength Min | 240 MPa (35,000 psi) | 275 MPa (40,000 psi) |
| Best Used For | Standard high-temp piping (Up to 427°C / 800°F) | Heavy-duty structural & high-pressure systems |
(Note: Total of Cr, Cu, Mo, Ni, and V shall not exceed 1.00% for both grades.)

Q: What is A106 pipe and what is ASTM A106 used for?
A: ASTM A106 pipe is a seamless carbon steel pipe for high-temperature service. Regarding what astm a 106 is used for, this premium astm a106 pipe is widely utilized in power plants, refineries, and petrochemical facilities to transport hot fluids and gases safely.
Q: What's the difference between A53 and A106?
A: ASTM A106 is strictly seamless for high-temperature systems, whereas A53 can be welded or seamless for low-pressure use. Mechanically, a106 gr b pipe contains added silicon for superior heat resistance compared to standard astm a 53 gr b.
Q: Which is better, ASTM A106 B or ASTM A53 B?
A: For high-temperature, high-pressure processing lines, astm a 106 gr b is superior due to its seamless thermal stability. However, for standard structural or plumbing applications, choosing astm a 53 gr b is more cost-effective than astm a106b.
Q: Which A106 pipe is better, B class or C class?
A: Grade C offers higher mechanical strength, but astm a106 grb is considered better for most projects. It provides excellent weldability and formability, making astm a106 b the global commercial standard and much easier to source.
Q: What is the pressure rating of ASTM A106 Grade B?
A: There is no fixed rating for astm a106 grb. It is calculated via Barlow's Formula based on wall thickness and outer diameter. Notably, the allowable pressure of astm a 106 gr b drops as the temperature rises toward its limits.
