Imibhobho yentsimbi engenamthungo inokwahlulwa ibe yi-ASTM yaseMelika esemgangathweni yemibhobho yentsimbi, iDIN yaseJamani imibhobho yentsimbi engenamthungo esemgangathweni, imibhobho yentsimbi esemgangathweni yeJIS yaseJapan, imibhobho yentsimbi yesizwe engenamthungo ye-GB, imibhobho yentsimbi engenamthungo ye-API kunye nezinye iindidi ngokwemigangatho yazo. Imibhobho yensimbi engenamthungo ye-ASTM yaseMelika isetyenziswa ngokuqhelekileyo kumazwe ngamazwe, kwaye iindidi zazo zahlukene. Iiparamitha ezifanelekileyo ze-ASTM zemibhobho yentsimbi engenamthungoI-ASTM i-a179/179m/sa179/sa-179m imibhobho yentsimbi engenamthungo yaseMelika zidweliswe ngolu hlobo lulandelayo.
isicelo
Ifanelekile kwimibhobho yentsimbi esetyenziswe kwi-tubular heat exchangers, i-condensers kunye nezixhobo ezifanayo zokudlulisa ukushisa.

Inkqubo yokuvelisa umbhobho wentsimbi engenamthungo. Ngokwenkqubo yokwenziwa kwayo, imibhobho yentsimbi engenamthungo yahlulahlulwe yaba yimibhobho yentsimbi eshushu eqengqelekayo, imibhobho yentsimbi etsalwa ngokubanda, imibhobho yentsimbi ekhutshiweyo neyoluliweyo, kunye nemibhobho yentsimbi engenamthungo ethe nkqo. Iinkqubo ezimbini zokuqala zisetyenziselwa ukuvelisa imibhobho yentsimbi engenamthungo jikelele, ububanzi bayo ngokuqhelekileyo buyi-8-406, kwaye ubukhulu bodonga ngokuqhelekileyo bu-2-25; ezi nkqubo zimbini zokugqibela zisetyenziselwa ukuvelisa imibhobho yentsimbi engenamthungo etyebileyo enodonga olukhulu, ubukhulu bayo buyi-406-1800, kwaye ubukhulu bodonga yi-20mm-220mm. Ngokusetyenziswa kwayo, inokwahlulwa ibeimibhobho yentsimbi engenamthungo yezakhiwo, imibhobho yentsimbi engenamthungo yolwelo, imibhobho yentsimbi engenamthungo yeebhoyila, kwayeimibhobho yentsimbi engenamthungo kwimibhobho yeoli.
