I-Matiale P11 P22 P5 P12 P9 P91 ASTM A335 Lega Di
Amapayipi ensimbi angenamthungo asetshenziswa kuzinhlelo zokusebenza ezidinga ukucaciswa okuphezulu ukuze kube lula ukufakwa nokunemba kokusebenza kanye nesicelo. Izinhlobo ezahlukahlukene zisetshenziselwa izinzuzo ezahlukene zemishini. Izicelo eziningi zidinga ukufudumala okuningi, ngakho-ke amapayipi ensimbi we-alloy alungile kubo. Abanye baphansi ngamandla kodwa baphakeme ekumelaneni nokugqwala, kanti abanye baphakeme ngamandla. Sinikeza amandla aphezulu wensimbi yamapayipi ensimbi aphansi kumabanga ahlukahlukene nosayizi.
Ekhuluma ngokuqinile, yonke insimbi iyi-alloy, kepha hhayi yonke insimbi ebizwa ngokuthi "ama-alloy steel". Ama-steel elula kakhulu yi-iron (FE) ahlanganiswe nge-carbon (c) (cishe ngo-0,1% kuya ku-1%, kuya ngohlobo) futhi akukho okunye (ngaphandle kokulandela okungalungile ngokungcola okuncane); Lokhu kubizwa ngokuthi ama-carbon sten. Kodwa-ke, igama elithi "i-alloy lensimbi" liyisikhathi esijwayelekile esibhekisa kuma-steel Ama-alloyants ajwayelekile afaka i-manganese (okuvame kakhulu), i-nickel, i-chromium, i-molybdenum, i-begadium, i-silico, ne-boron. Ama-alloya ajwayelekile ajwayelekile afaka i-aluminium, i-cobalt, yethusi, i-cersium, i-niobium, i-titanium, i-tungsten, uthini, i-zinc, ukuhola, ne-zirconium.
Okuqukethwe kuqukethe ikhabhoni, i-manganese, phosphorus, isibabule, i-silicon, 8% chromium ne-molybdenum engxenyeni. I-SA 335 Ibanga P5 Alloy Steel Pipe inamandla afanayo kumabanga amaningi ensimbi engagqwali, anamandla amancane ovunela angu-205MPA kanye namandla amancane ashubile angu-415MPA.
