| ASTM A252 Grade 2 | |
| ASTM A252/A252M | |
| High-Frequency Welding | |
ASTM A252 covers welded and seamless cylindrical steel pipe piles used as permanent load-carrying members or as shells for cast-in-place concrete piles. The standard permits electric-resistance-welded pipe, subject to its applicable requirements.
ASTM A252 Grade 2 Material Performance
ASTM A252 Grade 2 specifies a minimum yield strength of 240 MPa and a minimum tensile strength of 415 MPa. For nominal wall thicknesses of 7.9 mm or more, the minimum elongation is 25% over a 50.8 mm gauge length or 14% over a 203.2 mm gauge length. These mechanical properties support its use in foundation piles subjected to structural loading. HFW manufacturing provides an efficient method for producing longitudinally welded pipe, while dimensional inspection and weld quality testing can be arranged according to the applicable specification and project requirements.

Pipe-end protection is advisable in case the pipe-ends are bevelled at the pipe manufacturer. In the case of overseas transport, there is an especially increased risk of damaged pipe-ends. This is caused by extra handling procedures in ports and shifting of the pipes onboard vessels.
can be applied along the pipe body. This wrapping helps to safeguard the coating surface from scratches, moisture, and contamination during long-distance transportation or prolonged outdoor storage. Especially for coated or painted pipes, the additional protective cloth layer significantly reduces the risk of mechanical damage, UV exposure, and corrosion initiation, ensuring the pipes arrive at the destination in optimal condition.
In addition to pipe-end protection and external wrapping, Huayang provides customized to meet different project specifications and environmental requirements. Available options include water-based eco-friendly quick-drying paint, epoxy paint, quick-drying black paint, bituminous paint, and high-temperature-resistant paint. Paint type and application can be selected according to customer requirements, providing suitable surface protection for transportation, storage, and service conditions.
Beyond standard steel pipe manufacturing, Huayang provides customized deep processing services to meet different project and installation requirements. Our capabilities include flange welding, loose flange assembly, steel pipe piles, extra-long pipe joining, end beveling, and other fabrication services. Processing can be carried out according to customer drawings, technical specifications, and project requirements, helping customers reduce on-site fabrication work and improve installation efficiency.
