I-A335 P91 Incazelo
1) I-A335P91 iyimpahla yokucindezela okuphezulu kanye nensimbi ekwazi ukumelana nokushisa okuphezulu. Imigoqo ye-P91, amapuleti, amapayipi, ukufakwa kwamapayipi, i-p91 ngokuvamile
ebizwa nge-A355P91, elingana nezinga likazwelonke elithi 10Cr9Mo1VNb. Kuyimpahla yokucindezela okukhulu nokushisa okuphezulu
amapayipi ensimbi amelana. Izinga laseMelika yi-ASME SA-335/SA335M, amandla e-tensile ngu-≥ 585 (MPa), amandla okukhiqiza
≥ 415 (MPa), futhi ubude bungu-≥ 20 (%). Isici se-P91 ukuthi ubukhulu bodonga lwepayipi buncane. Mayelana
ukusetshenziswa kwezinto ezibonakalayo, kungaphansi kuka-40% kunezinye izinto zensimbi, futhi kungaphansi kuka-30% ngokonga
izinto zokwakha kanye nezindleko zokufaka. Njengoba isisindo esifile sepayipi le-P91 sincishisiwe, umthwalo wezisekelo nama-hangers nawo ulinganiselwe
kuncishisiwe, okulungele ukusekela nokuphakanyiswa, futhi okulula ukuklama nokufakwa.
2) I-German steel grade ehambisanayo ye-T91/P91 (10Cr9Mo1VNb) kanye nensimbi ye-P91 yi-X10CrMoVNNb91, i-Japanese steel grade
yi-HCM95, kanti i-French steel grade yi-TUZ10CDVNb0901.
3) Ingasetshenziswa njengamapayipi ensimbi okushisa okuphezulu kwe-superheater kanye nokushisa kabusha ngokushisa odongeni ≤ 625 ℃ ku-subcritical and
ama-boilers aphakeme kakhulu, kanye nokushisa okuphezulu kwekhanda namapayipi omusi anezinga lokushisa lodonga ≤ 600 ℃, kanye nogesi wenuzi
isishintshi sokushisa kanye namapayipi esithandweni somlilo esiqhekeza uwoyela.
Umbukiso wesitoko:
Isithombe sokupakisha:
Isicelo:
Amashubhu e-alloy asetshenziselwa kakhulu ukushisisa amashubhu angaphezulu kwama-boilers anengcindezi ephansi naphakathi (ingcindezi yokusebenza imvamisa.
hhayi mkhulu kuno-5.88Mpa, futhi izinga lokushisa lokusebenza lingaphansi kuka-450 ℃); Isetshenziselwa ukushisa amapayipi angaphezulu, i-economizers,
ama-superheaters, ama-reheaters, amapayipi emboni ye-petrochemical, njll. yama-boilers anengcindezi ephezulu (ingcindezi yokusebenza ngokuvamile
ngaphezu kwe-9.8Mpa, futhi izinga lokushisa lokusebenza liphakathi kuka-450 ℃ no-650 ℃)
