A252 Piles tubulaires sans soudure et soud\u00e9es Description<\/td>\n<\/tr>\n
La composition chimique du tube en acier A252 se compose principalement de fer, de carbone, de silicium, de mangan\u00e8se et d'autres \u00e9l\u00e9ments, dont la teneur en carbone est faible, seulement environ 0,2%. Les pieux en acier A252 ont d'excellentes propri\u00e9t\u00e9s m\u00e9caniques, une r\u00e9sistance et une t\u00e9nacit\u00e9 \u00e9lev\u00e9es, une r\u00e9sistance \u00e0 la traction g\u00e9n\u00e9ralement comprise entre 400 et 550MPa, et une bonne t\u00e9nacit\u00e9 \u00e0 basse temp\u00e9rature. Les pieux de tubes soud\u00e9s sans soudure A252 jouent un r\u00f4le important dans le p\u00e9trole, l'industrie chimique, la machinerie, la construction et d'autres domaines.<\/td>\n<\/tr>\n

L'ASTM A252 est la sp\u00e9cification standard pour les pieux cylindriques en acier \u00e0 paroi nominale, o\u00f9 le cylindre agit comme un \u00e9l\u00e9ment porteur permanent ou comme une coquille pour former un pieu en b\u00e9ton coul\u00e9 sur place. La sp\u00e9cification ASTM A252 comporte trois grades : Grade 1, Grade 2 et Grade 3, dont le Grade 2 et le Grade 3 sont des mat\u00e9riaux couramment utilis\u00e9s.<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n
