Iipayipi zentsimbi ezingenamthungo zinokwahlulwa 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 zifumaneka apha. Ixhaphake kakhulu kwihlabathi liphela kwaye ineentlobo ezininzi kunye namasebe.
Ngoku iiparameter ezifanelekileyo zombhobho wesinyithi ongenamthungo we-ASTM i-ASTM stm a210/a210m/astm sa210/sa-210s umbhobho wesinyithi ongenamthungo waseMelika zidweliswe ngolu hlobo lulandelayo:I-ASTM A210/A210M/ASME SA-210/SA-210M Injongo: ifanelekile kwiityhubhu zebhoyila kunye neebhoyila Iipayipi zeflue, kubandakanya iziphelo zokhuseleko, iivaults kunye neepayipi zokuxhasa, kunye nobukhulu obuncinci bodonga iipayipi zentsimbi yekhabhoni ephakathi ezingenamthungo kwiipayipi ze-superheater. Ivelisa ikakhulu amanqanaba epayipi yentsimbi: A-1, C, njl. Emva kwengxoxo, amanye amanqanaba eepayipi zentsimbi nawo anokubonelelwa.
Inkqubo yokuvelisa imibhobho yentsimbi engenamthungo:
Iipayipi zentsimbi ezingenamthungo zahlulwe zaba ziipayipi zentsimbi engenamthungo eziqengqelekayo ezishushu, iipayipi zentsimbi engenamthungo ezitsalwa kubanda, njl.njl. ngokwenkqubo yazo yokwenziwa. Ububanzi beepayipi zentsimbi engenamthungo ngokubanzi yi-406mm-1800mm, kwaye ubukhulu bodonga yi-20mm-220mm. Ngokwendlela ezisetyenziswa ngayo, zingahlulwa zibeimibhobho yentsimbi engenamthungo yezakhiwo, imibhobho yentsimbi engenamthungo yolwelo, imibhobho yentsimbi engenamthungo yeebhoyilakunyeimibhobho yentsimbi engenamthungo yemibhobho yeoyile.
