Grade 2

ASTM A252 Grade 2 steel pipe is one of the most commonly used pile pipes. Piling pipes serve as the foundation of the building sector. Because of their tremendous strength, they are thought to be employed in applications that need strong structural qualities. ASTM A252 is a standard that deals with the issue. The cylindrical ASTM A252 Grade 2 Pipe is used for piling, either as a shell for a cast concrete pile or as a permanent element carrying weight in the specified application. This specification encompasses the nominal wall of the cylindrical steel piling pipe.
  • APPLICATIONS OF ASTM A252 GRADE 2 PILING PIPE

    ASTM A252 Grade 2 pipe piling is being developed for use in a direction with deep distances and large diameters due to the increasing height of structures, buildings, and bridges. The cylindrical design of ASTM A252 Grade 2 pipe is suitable for a wide range of applications, including building retaining walls, different types of buildings that need a tough base, and bridges. This guarantees that construction using this type of pipe is solid, stable, and of the greatest quality – meeting international quality standards. large diameter pipes are essential in the construction world due to their many purposes and benefits. They help ensure the stability and strength of tall structures while also providing a variety of other benefits. This makes them an essential part of many large-scale construction projects. Consequently, developers must continue to create large-diameter pipes that meet the needs of these projects. This will help to ensure that these projects can be completed safely and effectively.

  • CHEMICAL COMPOSITION OF ASTM A252 GRADE 2 STEEL PILING PIPE

    The standard specifies the requirements for ASTM A252 Grade 2 welded and seamless steel pipe piles. The chemical analysis is a critical part of confirming compliance with this standard. The analysis shall be performed in accordance with test methods, practices, and terminology ASTM A751. A minimum of two samples shall be taken from each heat lot of pipe piles, and analyses shall be made on these samples. Therefore, it is important to carefully review the specification and make sure that the correct analyses are being performed.
  • MECHANICAL PROPERTIES OF ASTM A252 GRADE 2 PILING PIPES

    The ASTM A252 Grade 2 pipes must meet the minimum requirements for tensile strength, as outlined in the tables below. The yield point is the point at which the specimen (whether it be a beam, gage, divider, etc.) is deemed to have failed the test, and is usually determined by observing the point at which permanent deformation occurs. If no definite yield point can be observed, then the yield strength must correspond to either a 0.2% permanent offset of the original gage length or a 0.5% total extension under load. These methods for determining yield strength are essential in ensuring that the material meets the minimum requirements for use. Without these standards in place, materials could be used that are not up to par, leading to subpar performance and potential disaster. Thus, these requirements serve an important role in protecting both people and property.

  • PERMISSIBLE VARIATIONS OF ASTM A252 STEEL PILING PIPES

    • According to this standard, each length of ASTM A252 Grade 2 pipe pile must be weighed separately. The weight of the pipe must not vary more than 15% over or 5% under its theoretical weight. This weight can be calculated using the pipe’s length and its weight per unit length. If the purchase order does not specify a weight, the manufacturer must ensure that the pipe conforms to the specified calculation formula.


    • The outside diameter of pipe piles shall not deviate by more than 1% from the diameter specified.
    • The wall thickness at any location shall not deviate by more than 12.5% from the nominal thickness.
