ASTM A252 Piling Pipe

ASTM A252 is the American standard, specializing in the production of welded and seamless steel pipe piles. This material is best known for its capacity to act as a powerful and reliable load-carrying member. With its specialized cylinder shape, ASTM A252 serves dual purposes – either as a stalwart load-carrier or as a protective shell for cast-in-place concrete piles.

Our steel pipe piles are available in both seamless and welding processes (including ERW, SSAW, and LSAW), ensuring flexibility for diverse construction needs. The steel pipe piles are available in different grades, with ASTM A252 grade 3 being a prominent choice for its exceptional welding performances and high yield strength. Opting for ASTM A252 assures you of a product that’s tailored for strength, ensuring the base of your constructions is both solid and enduring.

ASTM A252 Specification

When it comes to specifications, ASTM A252 is precise. These pipe piles can be both welded and seamless products. Manufactured using a variety of processes, including hot rolling, cold drawing, and various furnace methods, their versatility stands out. ASTM A252 pipes also differ from other pipelines in that they don’t require a hydrostatic test – primarily because they’re used for foundation stability rather than liquid transmission. Surface imperfections are strictly regulated, with defects deeper than 25% of the nominal wall considered unacceptable.

ASTM A252 steel pipe piles are available in different shapes, including the distinctive cylinder shape and rectangular pipe, catering to diverse construction needs. Whether you require seamless steel pipe piles or welded options, we supply a comprehensive range of products to meet your specifications.

Chemical Requirements of ASTM A252

ASTM A252 has specific criteria when it comes to chemical components. Primarily, the content of phosphorous must not exceed 0.050%. Higher amounts can compromise the steel’s durability and welding properties. While this standard specifically defines the content of phosphorous, other elements should accord with general carbon steel material norms.

Mechanical Requirements of ASTM A252

Mechanical stability is paramount in ASTM A252 pipes. Both tensile and yield strengths are rigorously tested to ensure the pipe can withstand the intense forces of construction activities. Especially in Grade 3 pipes, the tensile strength can reach up to 455 Mpa or 66,000 psi, and yield strength can hit 310 Mpa or 45,000 psi. Whether you choose seamless or welded processes, our supply of ASTM A252 pipes aligns with these mechanical specifications, guaranteeing the reliability and performance of the steel products.

Steel Grades in ASTM A252

With ASTM A252, there are three primary grades: Grade 1, Grade 2, and the most commonly used, Grade 3. These classifications are based on tensile strength and yield strength, with Grade 3 being the most robust, making it a top choice for piling activities.

Whether you’re considering seamless steel pipe piles, electric resistance welded options, or thermal expanded seamless pipes, ASTM A252 Grade 3 is often the preferred choice due to its superior strength characteristics. The cylindrical shape of these steel pipe piles, whether in round pipes or rectangular forms, is meticulously designed to meet specific standards.
