Iipayipi zentsimbi ezingenamthungo zingahlulwa zibe ziipayipi zentsimbi ezingenamthungo zaseMelika ze-ASTM, iipayipi zentsimbi ezingenamthungo zaseJamani ze-DIN, iipayipi zentsimbi ezingenamthungo zaseJapan ze-JIS, iipayipi zentsimbi ezingenamthungo zaseJapan ze-GB, iipayipi zentsimbi ezingenamthungo ze-API kunye nezinye iintlobo ngokwemigangatho yazo. Iipayipi zentsimbi ezingenamthungo zaseMelika ze-ASTM zisetyenziswa kakhulu kumazwe ngamazwe, kwaye iintlobo zazo zahlukile. Iiparameter ezifanelekileyo zeepayipi zentsimbi ezingenamthungo ze-ASTMI-ASTM a179/179m/sa179/sa-179m Imibhobho yentsimbi engenamthungo yaseMelika esemgangathweni idweliswe ngolu hlobo lulandelayo
isicelo
Ifanelekile kwiipayipi zentsimbi ezisetyenziswa kwi-tubular heat exchangers, i-condenser kunye nezixhobo ezifanayo zokudlulisa ubushushu.

Inkqubo yokwenziwa kwemibhobho yentsimbi engenamthungo. Ngokwenkqubo yayo yokwenziwa, imibhobho yentsimbi engenamthungo yahlulwe yaba yimibhobho yentsimbi engenamthungo eshushu, imibhobho yentsimbi engenamthungo etsalwa kubanda, imibhobho yentsimbi engenamthungo ebhoboziweyo neyoluliweyo, kunye nemibhobho yentsimbi engenamthungo ekhutshwe ngokuthe nkqo. Iinkqubo ezimbini zokuqala zisetyenziselwa ukuvelisa imibhobho yentsimbi engenamthungo eqhelekileyo, ububanzi bayo buyi-8-406, kwaye ubukhulu bodonga buyi-2-25; iinkqubo ezimbini zokugqibela zisetyenziselwa ukuvelisa imibhobho yentsimbi engenamthungo enkulu, ububanzi bayo buyi-406-1800, kwaye ubukhulu bodonga buyi-20mm-220mm. Ngokwendlela esetyenziswa ngayo, inokwahlulwa ibeimibhobho yentsimbi engenamthungo yezakhiwo, imibhobho yentsimbi engenamthungo yolwelo, imibhobho yentsimbi engenamthungo yeebhoyilakunyeimibhobho yentsimbi engenamthungo yemibhobho yeoyile.
