ASTM A252 PILING PIPE
- Commodity name： ASTM A252 PILING PIPE

Details
- 产品描述
-
ASTM A252 is a standard developed by the American Society for Testing and Materials (ASTM) specifically for the production and application of Piling Pipe. This type of steel pipe is mainly used in deep foundation projects (such as pile foundation construction), providing vertical or horizontal support for structures like buildings, Bridges, and docks.
1. Scope of application of the standard
• Main uses: ASTM A252 pile pipes are typically used for support piles (bearing vertical loads) or retaining walls (bearing lateral earth pressure)- Building foundation (high-rise buildings, industrial plants)
- Bridge piers and abutments
- Offshore platforms and docks
- Anti-landslide project
- Temporary support structures (such as foundation pit support)
• Working environment: It can be directly driven into soil, rocks or underwater, and must have good compressive strength, bending resistance and corrosion resistance.
2. Material grades and mechanical properties
ASTM A252 classifies pile pipes into three grades, and the strength and application of different grades vary:
Grade Minimum yield Strength (MPa) Minimum Tensile Strength (MPa) Typical Application scenarios Grade 1 207 345 Low-load scenarios, such as temporary support, lightweight buildings Grade 2 241 414 Medium load, such as ordinary building pile foundation Grade 3 310 483 High load or harsh environments, such as Bridges and docks Note: The material is usually carbon steel, and the chemical composition is not strictly limited, but it must meet the mechanical property requirements.
3. Manufacturing process and dimensions
• Manufacturing method:- Welded steel pipes: Commonly used are resistance welding (ERW) or submerged arc welding (SAW), which have relatively low costs.
- Seamless steel pipes (less common) : used for special high-strength requirements, but they are more expensive.
• Size range:
- Outer diameter: Usually 6 inches (168.3mm) to 36 inches (914mm).
- Wall thickness: Wide range, commonly from 0.25 inches (6.35mm) to 1.5 inches (38.1mm).
- Length: The standard length is 20 feet (6.1m) or 40 feet (12.2m), and customization is available.
4. Technical Requirements and Testing
• Mechanical performance test:
- Tensile test: Verify yield strength, tensile strength and elongation.
- Bending test: Ensure that the steel pipe does not crack during cold bending (the sample bends 180° without defects).
- Flattening test (optional) : Evaluate the ductility of the weld area.
• Other tests:
- Hydraulic test: Ensure that there is no leakage in the steel pipe (the pressure is calculated by the formula and is usually 70-300 psi).
- Non-destructive testing (NDT) : Such as ultrasonic testing (UT) or eddy current testing (ET), used for weld quality inspection (optional according to engineering requirements).
5. Surface treatment and protection
• Surface quality: The inner and outer surfaces of the steel pipe should be free of cracks, scars and other defects, and slight oxide scale is allowed.
• Anti-corrosion measures:
• Coating: Epoxy resin, asphalt or galvanizing can be applied (non-standard requirements, subject to separate regulations).
• Cathodic protection: It is used in Marine or highly corrosive environments and requires coordination with engineering design.
6. Comparison with other standards
• API 5L: API 5L focuses on oil and gas transportation pipes, emphasizing chemical composition and high-pressure sealing performance, while ASTM A252 pays more attention to mechanical strength and structural support capacity.
• EN 10219: Structural steel tubes in the European standard have stricter requirements for welding techniques and tolerances.
7. Selection and Construction Precautions
• Selection basis:
Determine the load requirements based on the geological report.
• Consider the corrosive environment： (choose wall thickness redundancy or additional anti-corrosion measures).
• Construction key points:
The end of the pile can be welded with reinforcing rings or pile boots can be set up to improve penetration.
When driving piles, the hammering energy should be controlled to avoid local buckling of the steel pipes.
8. Marketing and Purchasing
• Main production areas:
China, the United States, Japan and Europe are the main production sites.
• Price factors:
Affected by steel prices, wall thickness, anti-corrosion treatment, etc., it is usually priced by the ton.
• Certification Requirements:
A material certificate (MTC) is required. Some items require third-party inspection (such as SGS, BV).
Summary
ASTM A252 pile pipe is a key material in deep foundation engineering. Its high strength and ease of construction make it an ideal choice for civil engineering. When selecting the type, the load, environment and cost should be comprehensively considered, and the test requirements in the standard should be strictly followed to ensure the safety of the structure.
