Amapayipi ensimbi angenamthungo ajwayelekile e-ASTM American akhona. Avamile emhlabeni wonke futhi anezinhlobo eziningi namagatsha.
Manje amapharamitha afanele epayipi lensimbi elingenamthungo le-ASTM ipayipi lensimbi elingenamthungo le-ASTM stm a210/a210m/astm sa210/sa-210s laseMelika abhalwe kanje:I-ASTM A210/A210M/ASME SA-210/SA-210M Inhloso: ifanele amashubhu ebhoyila nama-boiler Amapayipi omoya, okuhlanganisa iziphetho zokuphepha, ama-vault namapayipi okusekela, kanye nobukhulu obuncane bodonga amapayipi ensimbi ekhabhoni ephakathi nendawo angenamthungo amapayipi e-superheater. Ikhiqiza kakhulu amazinga epayipi lensimbi: A-1, C, njll. Ngemva kokuxoxisana, amanye amazinga amapayipi ensimbi nawo anganikezwa.
Inqubo yokukhiqiza amapayipi ensimbi angenamthungo:
Amapayipi ensimbi angenamthungo ahlukaniswe ngamapayipi ensimbi angenamthungo ashiswayo, amapayipi ensimbi angenamthungo adonswayo abandayo, njll. ngokwenqubo yawo yokukhiqiza. Ububanzi bamapayipi ensimbi angenamthungo ngokuvamile bungu-406mm-1800mm, kanti ubukhulu bodonga bungu-20mm-220mm. Ngokwendlela asetshenziswa ngayo, angahlukaniswa abeamapayipi ensimbi angenamthungo ezakhiwo, amapayipi ensimbi angenamthungo oketshezi, amapayipi ensimbi angenamthungo amabhoyila, futhiamapayipi ensimbi angenamthungo amapayipi kawoyela.
