Sie umfasst nahtlose, kaltgezogene Kohlenstoffstahlrohre mit Mindestwandst\u00e4rke, einschlie\u00dflich der Biegung in Form von U-Rohren. Es wird f\u00fcr die Herstellung einer Wasserk\u00fchlwand des Kraftwerkskessels verwendet, es kann effektiv den Dampffilm auf der Innenwand des Stahlrohrs beseitigen und die thermische Effizienz der Feuerungswand verbessern. F\u00fcr diese Spezifikation gibt es drei G\u00fcteklassen: Klasse A2, B2, C2, wobei B2 und C2 am h\u00e4ufigsten verwendet werden.<\/p>\n<ul>\n<li>Spezifikation: ASTM A556 B2<\/li>\n<li>Au\u00dfendurchmesser: 20mm-31,8mm<\/li>\n<li>Wanddicke::1,1mm-35mm<\/li>\n<li>L\u00e4nge: 3m-12m<\/li>\n<li>Lieferzustand: NBK, Hell, U-Biegen.<\/li>\n<\/ul>\n<h3><\/h3>\n<h3><\/h3>\n<h3><\/h3>\n<h3>ASTM A556 B2 Rohr Chemie Zusammensetzung<\/h3>\n<table>\n<tbody>\n<tr>\n<td width=\"142\">Klasse<\/td>\n<td width=\"142\">C<\/td>\n<td width=\"142\">Si<\/td>\n<td width=\"142\">Mn<\/td>\n<td width=\"142\">P<\/td>\n<td width=\"142\">S<\/td>\n<\/tr>\n<tr>\n<td width=\"142\">B2<\/td>\n<td width=\"142\">\u22640.27<\/td>\n<td width=\"142\">\u22650.10<\/td>\n<td width=\"142\">0.29-0.93<\/td>\n<td width=\"142\">\u22640.035<\/td>\n<td width=\"142\">\u22640.035<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<h3><\/h3>\n<h3>ASTM A556 B2 Rohre Mechanische Eigenschaften<\/h3>\n<table>\n<tbody>\n<tr>\n<td width=\"170\">Klasse<\/td>\n<td width=\"170\">Zugfestigkeit MPa<\/td>\n<td width=\"170\">Streckgrenze MPa<\/td>\n<td width=\"170\">Dehnung<\/td>\n<td width=\"170\">H\u00e4rte HRB<\/td>\n<\/tr>\n<tr>\n<td width=\"170\">B2<\/td>\n<td width=\"170\">410 min<\/td>\n<td width=\"170\">260 min<\/td>\n<td width=\"170\">35<\/td>\n<td width=\"170\">79 min<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<h3><\/h3>\n<h3><\/h3>\n<h3><\/h3>\n<h3><\/h3>\n<p>ASTM A556, ASME SA 556steel pipe is mainly for a high-temperature heater system.
