ASME SA106 Grade B Seamless Steel Pipe​

ASME SA106 Grade A Seamless Steel Pipe in compliance with ASME SA106 standards is a high-quality seamless carbon steel pipe widely used in the industrial field. As a classic Carbon Steel Pipe, it adopts a seamless forming process and has excellent strength, weldability and economy. It can stably adapt to conventional working conditions such as oil and gas transportation, water supply and drainage systems, and mechanical manufacturing. In medium and low pressure scenarios, its cost performance far exceeds that of Alloy Steel Pipe. ​

For different Temperature requirements, this Pipe material is flexibly adapted: In scenarios of low-temperature fluid transportation (such as cold storage pipelines), it can be used in combination with Low Temperature Steel Pipe to avoid the risk of brittle cracking at low temperatures; Although the heat resistance of the conventional type is not as good as that of High Temperature Steel Pipe, after being treated by ASME standard process, it can withstand a certain medium and high temperature environment and can be used as an auxiliary pipeline of Boiler Pipe to adapt to the low-temperature return water system of boilers. Furthermore, it features precise size control of Precision Steel Pipe, a smooth inner wall to reduce the resistance of medium flow, a tight interface to prevent leakage, and strictly meets the requirements of ASME SA106 Grade B standards, providing a reliable solution for industrial projects that pursue a balance between cost and performance. ​

Key Features and Specifications​​:
​​1. Chemical Composition​​
​​Carbon (C)​​: ≤0.25% (low carbon for weldability and formability).
​​Manganese (Mn)​​: 0.27 - 0.93(enhances strength and toughness).
​​Silicon (Si)​​: ≥0.10 (improves oxidation resistance).
​​Other elements​​ (e.g., sulfur, phosphorus): Strictly controlled to ≤0.035% (S) and ≤0.035% (P) for minimal impurity effects. As a type of Carbon Steel Pipe, it lays a solid foundation with its carefully regulated composition.
​​2. Mechanical Properties​​
​​Yield Strength​​: ≥205 MPa (29730 psi)-meeting the requirements of Precision Steel Pipe, ensuring reliable performance under stress.
​​Tensile Strength​​: ≥330MPa (34090 psi)-adequate for standard Boiler Pipe systems, especially those used in low - to medium - pressure boilers.
​​Elongation​​: ≥28% indicating good ductility, which is crucial for various fabrication processes of Steel Tube For Boiler and other pipe applications.
​​3. Temperature and Pressure Ratings​​
​​Maximum Service Temperature​​: Typically up to ​​450°C (842°F)​​ for short-term exposure; long-term use is limited to lower temperatures (~400°C) to avoid creep and graphitization. These temperature limits make it suitable for certain sections of boiler systems where temperatures are within its tolerance range.
​​Pressure Rating​​: Designed for ​​medium-pressure applications​​ (e.g., low-pressure boilers, non-critical steam lines), making it a common choice for many boiler pipe installations.
​​4. Applications​​
​​Low- to Medium-Pressure Boilers​​: Ideal for components like steam headers, economizers, or other parts in boiler systems operating below Grade B/C specifications, serving as a reliable Steel Tube For Boiler in such setups.
​​Light Industrial Systems​​: Used in HVAC, water heaters, or non-corrosive fluid transport, demonstrating its versatility as a Carbon Steel Pipe.
​​Structural Supports​​: Applicable for non-critical structural components in high-temperature environments, complementing other types of pipes like Alloy Steel Pipe in more comprehensive industrial projects.
​​5. Fabrication and Weldability​​
​​Formability​​: High ductility supports bending, flanging, and coiling, which is beneficial for the manufacturing of various Precision Steel Pipe products and custom - made Boiler Pipe components.
​​6. Standards Compliance​​
Conforms to ​​ASME SA-106 Grade A​​, ensuring dimensions, tolerances, and mechanical properties meet industry benchmarks. This compliance makes it a trustworthy option among different types of pipes, including those used in boiler and precision applications.
​​7. Limitations​​
​​Not suitable for​​:
High-pressure or high-temperature applications (use Grades B/C instead), where Alloy Steel Pipe or higher-grade Carbon Steel Pipe might be more appropriate.
Corrosive environments (requires coatings or lining), highlighting the need for proper protection or alternative materials in such conditions.
Cryogenic services (low-temperature brittleness), emphasizing the importance of material selection based on specific operational requirements.
​
​​Key Considerations​​
​​Cost-Effective​​: Lower carbon and simpler processing make Grade A more economical than higher grades.​ This cost - effectiveness makes it an attractive option for projects where budget is a major concern, while still providing reliable performance for applications such as Steel Tube For Boiler, Precision Steel Pipe, and Carbon Steel Pipe in less demanding scenarios.
SA106 Grade A is ideal for cost-sensitive projects with moderate temperature and pressure demands. For harsher conditions, consider upgrading to Grade B or C.
