ASTM A234 Gigun Welded Pipe
Ṣafihan:
Ni agbaye ti awọn paipu irin, awọn ọrọ ti o wọpọ kan wa nigbagbogbo: paipu welded gigun.Awọn paipu yii ṣe ipa pataki ni ọpọlọpọ awọn ile-iṣẹ ati ṣe iranṣẹ fun ọpọlọpọ awọn idi.
Gigun welded paipu, tun mo bi taara pelu welded pipe, ni a irin paipu ṣe ti gbona-yiyi tabi tutu-yiyi irin awo tabi irin rinhoho okun.Orukọ wọn wa lati ilana alurinmorin, eyiti o waye ni laini taara ni gigun ti paipu naa.Ọna yii ṣe idaniloju didara weld deede ati awọn isẹpo wiwọ, idilọwọ awọn n jo ati imudara iduroṣinṣin igbekalẹ gbogbogbo.
