ASTM A252 refers to the American Society for Testing and Materials (ASTM) standard specification for welded and seamless steel pipe piles. This specification covers the requirements for cylindrical steel pipe piles in various grades and sizes. ASTM A252 ssaw steel pipe, also known as spiral submerged arc welded (SSAW) pipe, is a type of pipe that is manufactured using the spiral welding process. In this process, steel strips are formed into a spiral shape and welded along the seam using submerged arc welding methods. ASTM A252 spiral carbon steel pipe is commonly used for deep foundation applications such as the construction of pile foundations, marine structures, bridge piers, and retaining walls. The spiral welding process allows for the production of large-diameter pipes with excellent strength and load-bearing capacity. These pipes are available in different grades, namely Grade 1, Grade 2, and Grade 3, which correspond to different minimum yield strengths. T…
