ASTM A709 A500 Welded Carbon Steel Pipes for Structure Bridge

Our welded carbon steel pipes compliant with ASTM A709 and ASTM A500 standards are engineered to be the cornerstone of robust and reliable structure bridges, combining high - quality materials, precise manufacturing, and excellent performance.

1. Standard - Based Material Properties

Standard	Material Grade	Key Material Features
ASTM A709	Grades 36, 50, 50W, HPS 70W, etc.	Specifically designed for bridge construction, these grades offer high strength, good toughness, and excellent weldability. For example, Grade 50 provides a minimum yield strength of 345 MPa, ensuring the pipe can withstand heavy loads. The "W" in grades like 50W and HPS 70W indicates weathering resistance, reducing the need for extensive maintenance in outdoor bridge environments.
ASTM A500	Grades A, B, C, D	Manufactured through cold - forming processes, these grades offer a balance of strength and ductility. Grade B, for instance, has a minimum yield strength of 248 MPa, making it suitable for various bridge structural components. The cold - forming process enhances the material's mechanical properties, allowing for precise shaping to meet different bridge design requirements.

2. Dimensional Specifications

Dimension Aspect	Details
Outer Diameter (OD)	Ranging from 1/2 inch to 24 inches (12.7 mm - 609.6 mm), catering to diverse bridge structural needs. Smaller diameters can be used for intricate details or support in pedestrian bridges, while larger diameters are ideal for main load - bearing components in large - scale highway bridges.
Wall Thickness	Varies from thin - walled options for lightweight structures to thick - walled for high - load applications, typically ranging from 0.065 inches to 1.5 inches (1.65 mm - 38.1 mm). The precise wall thickness is carefully calculated to ensure the pipes can bear the expected loads while maintaining an optimal weight - strength ratio.
Length	Available in standard lengths of 20 feet, 40 feet (6.1 m, 12.2 m), etc., and can also be customized according to bridge project requirements. Custom lengths reduce the need for excessive on - site cutting and welding, improving construction efficiency.

3. Performance Advantages

• High Strength and Load - Bearing Capacity:With their stringent material and manufacturing requirements under ASTM A709 and ASTM A500, these pipes can bear heavy traffic loads, wind forces, and seismic activities, providing long - term stability for bridge structures.

• Superior Weldability:Designed to be easily welded, they allow for seamless integration into complex bridge frameworks. High - quality welding ensures strong connections between pipe segments, enhancing the overall structural integrity of the bridge.

• Corrosion Resistance:Grades with weathering resistance in ASTM A709 and the appropriate surface treatments available for ASTM A500 pipes offer excellent protection against corrosion. This significantly extends the service life of the bridge, reducing maintenance costs over time.

• Ductility and Impact Resistance:The materials' ductility enables the pipes to deform without sudden failure under stress, while their impact resistance helps them withstand unexpected forces, ensuring the safety of the bridge and its users.

4. Quality Assurance

Quality Control Measure	Description
Material Testing	Rigorous chemical composition analysis and mechanical property tests are conducted on raw materials to ensure compliance with ASTM A709 and ASTM A500 standards. Tensile tests, yield strength tests, and impact tests are performed to verify the material's performance.
Welding Inspection	Welding processes are closely monitored, and non - destructive testing methods such as ultrasonic testing and radiographic testing are employed to detect any internal flaws in the welds, ensuring the quality and reliability of the welded joints.
Dimensional Inspection	Precise measurement of outer diameter, wall thickness, and length is carried out to ensure the pipes meet the specified dimensional tolerances, guaranteeing a perfect fit during bridge construction.
Surface Inspection	Visual inspection is conducted to check for any surface defects, such as cracks, dents, or unevenness, ensuring that only pipes with high - quality surfaces are delivered for bridge projects.

5. Application Scenarios

• Highway Bridges:Ideal for the main girders, columns, and bracing systems of highway bridges, these pipes can support the heavy loads of continuous vehicle traffic while withstanding environmental factors like rain, snow, and temperature changes.

• Railway Bridges:Used in the construction of railway bridges to bear the weight of trains and the dynamic forces generated during train movement. Their high strength and stability ensure safe and smooth railway operations.

• Pedestrian Bridges:For pedestrian bridges, the pipes can be used to create aesthetically pleasing and structurally sound designs, providing a safe passage for pedestrians while adding to the architectural beauty of the bridge.

• Coastal Bridges:In coastal areas, the weathering - resistant grades under ASTM A709 and corrosion - protected ASTM A500 pipes are perfect choices, as they can withstand the corrosive effects of saltwater and sea air, maintaining the bridge's integrity over time.

6. Packaging and Delivery

• Packaging:The pipes are carefully packaged with protective materials to prevent damage during transportation. They are bundled securely and labeled clearly with relevant product information, including standard compliance, grade, and dimensions.

• Delivery:We offer fast and reliable global delivery services, working with experienced logistics partners. Timely delivery is ensured to meet the construction schedules of bridge projects, helping contractors complete their work efficiently.
