alloy insimbi yamapayipi 8 Ibanga 8 Ipayipi ASTM A333 esitokweni
Amashejuli ayahlukahluka ngokususelwa kububanzi obukhulu obunobukhulu maqondana nobukhulu bodonga. Amashejuli aqala kusuka ku-SCH20 kuya kuma-xxs. Ubude bephapha bufika ku-13500 mm. Kunamapayipi angenamthungo kanye namapayipi afakiwe kulolu ncazelo. I-ASTM A335 P5 Pipe ingaba yindilinga, i-hydraulic, unxande, isikwele noma i-hexagonal. Ubude bepayipi nabo bungasikwa usayizi wobude ngokuya ngezidingo zamakhasimende.
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.
I-ASTM A320 Ibanga L7 Ukucaciswa okuhlanganisa izinto ezingagqwali zensimbi ezingagqwali zensizakalo yokushisa ephansi. Lesi simbozo esijwayelekile sisongelwe, sakhiwa, noma ama-shigwala imigoqo eqinile, ama-bolts, ama-screws, ama-stud, kanye nama-bolts asetshenziselwa ukusetshenziselwa ukucindezela, ama-valves, amavutha, kanye nokufakelwa.
