ASTM A53 is the American Society for Testing and Materials' uncoat and hot-dip galvanized welded and seamless nominal steel pipes. There are two levels of materials, namely A and B. Grade A is equivalent to No. 10 steel, and Grade B is equivalent to No. 20 steel. There are three types, type F is continuous butt welded pipe in grade A furnace, type E is resistance welded pipe of grade A e B, e tipo S é sem costura aço tubo de grau A e B.
O especificações de ASTM A53 Grade B aço tubo são tração resistência Maior que ou igual a 415 (MPa) e rendimento força Maior que ou igual a 240 (MPa).
Química Composição: O aço usado em ASTM A53 Grade B tubos deveria conforme a o necessário químico composição de carbono, manganês, fósforo, enxofre, cobre, níquel, cromo, molibdênio, e vanádio.
Mecânica Propriedades: ASTM A53 Grade B pipes should have minimum tensile strength of 60,000 psi (415 MPa) and minimum yield strength of 35,000 psi (240 MPa).
Testes: ASTM A53 Grade B pipes undergo various tests incluindo hidrostática teste, flattening test, tensile test, and bend test to ensure compliance with specified requirements.
Uso: ASTM A53 Grade B pipes are commonly used for conveying gas, water, oil, and other fluids in various industries include construction, plumbing, and mechanical applications.
