Amardeep Steel is a leading supplier of ASTM A252 Grade 1 pipes are steel piling pipes used in construction for large diameter and structure applications, ASTM A252 pipes are made to meet requirements for chemical composition, mechanical properties, and dimensions.
ASTM A252 Grade 1 steel pipe is a widely used material in construction, particularly for pipe piles. A252 pipe serves as permanent load-carrying elements or as shells for cast-in-place concrete piles. Designed to provide strong support, ASTM A252 Grade 1 pipes are ideal for large-scale construction and structural applications, such as building foundations and bridge construction.
Astm A252 Steel Pipe are typically characterized by their large diameter, which helps distribute the load evenly across the structure. This makes them especially useful in regions prone to earthquakes or other natural disasters, where stability and durability are paramount.
Regarding surface imperfections, any flaw that exceeds 25% of the nominal wall depth is considered a defect. If the defect is less than 22.5% of the nominal wall, it can be repaired through welding, but the defect must be fully removed before proceeding with the weld. The high-quality materials used in ASTM A252 Grade 1 pipes ensure they are capable of withstanding harsh environmental conditions and heavy structural loads, making them an essential component in many significant construction projects.
According to ASTM A252 Grade 1 standards, each length of pipe pile must be weighed individually to ensure that its weight falls within a specified range. The weight should not vary by more than 15% above or 5% below the theoretical weight, which is calculated based on the pipe’s length and weight per unit length. If the weight is not mentioned in the purchase order, it is the manufacturer’s responsibility to ensure the pipe meets the required weight specifications.
Additionally, the outside diameter of Astm A252 Steel Pipe piles must not deviate more than 1% from the specified diameter. The wall thickness at any point along the pipe should not deviate by more than 12.5% from the nominal thickness, ensuring consistency and reliability in the material’s performance for its intended structural uses. These specifications ensure that ASTM A252 Grade 1 pipe piles maintain the necessary strength and durability for demanding construction applications.
What is the difference between ASTM A500 and A252?
The tolerances in A252 are more lenient thanASTM A500 Pipe for wall thickness and it has no tolerance for straightness. A252 has a -12.5% wall thickness tolerance. Remember that A500 has a -10% wall tolerance, which is what is the 0.93 factor in AISC 360-16 Section B4. To know more about A252 grade 1 pipes & tubes price please feel free to contact us.

ASTM A252 Pipe Chemical Composition
Chemical analysis is a vital part of the process when ordering ASTM A252 Grade 1 steel pipes. The chemical analysis shall be performed according to the test methods, practices, and terminology specified in ASTM A751. To ensure accuracy, the buyer is entitled to conduct product analyses using two samples from each heat lot of pipe piles. This way, any potential issues can be identified and rectified before the pipes are put into use. By ensuring that the correct procedures are followed, it is possible to order ASTM A252 Grade 1 steel pipes with confidence, knowing that they will meet the required standards.

FAQs
1. What is ASTM A252 material?
ASTM A252 is the standard specification for welded and seamless steel pipe piles. It covers the nominal wall thickness of the cylinder-shaped steel pipe; the rectangular pipe is not included. These round pipes are used for piling purposes, playing as a permanent role of load carrying and bearing the pressure.
2. What is the yield strength of ASTM A252?
ASTM A252 Grade 3 is the most commonly used pipe piling material. It offers high tensile strength (455 MPa or 66,000 psi) and yield strength (310 MPa or 45,000 psi), making it ideal for piling activities.
3. What is ASTM A252?
The ASTM A252/A252M-19 specification serves as the standard industry reference for welded steel cylinders, which serve either as a load-carrying member or as a shell to form cast-in-place concrete piles.
