I-ASTM A335 P92 (ASME SA335 P92) iyipayipi lensimbi ye-ferritic alloy engenamthungo eyenzelwe isevisi yokushisa okuphezulu.Isikhundla se-UNS yi-K92460.
I-P92 iyinsimbi ye-alloy enamandla e-chromium martensitic engashisi kakhulu equkethe i-chromium engu-8.50–9.50% futhi ixutshwe ne-Mo, W, V, kanye ne-Nb, enikeza amandla amahle kakhulu okushisa okuphezulu, ukumelana nokushiswa kwe-oxidation, kanye nokumelana nokukhathala kokushisa.
Isetshenziswa kabanzi emigqeni emikhulu yomusi, emigqeni yomusi yokuvuselela, emashubhini okushisa okuphezulu kanye nokuvuselela kabusha ama-boilers anamandla abucayi kakhulu nabucayi kakhulu, kanye nasemapayipini okushisa aphezulu, anengcindezi ephezulu kanye nezingxenye ezigcina ingcindezi ebalulekile ezindaweni ze-petrochemical kanye nezokuhlanza.
I-Botop Steel ingumthengisi wepayipi lensimbi ye-alloy ochwepheshe futhi othembekile eShayina, okwazi ukuhlinzeka ngokushesha amaphrojekthi akho ngamapayipi ensimbi ye-alloy alloy ahlukene, okuhlanganisaI-P5 (K41545), I-P9 (K90941), P11 (K11597), P12 (K11562), I-P22 (K21590), futhiI-P91 (K90901).
Imikhiqizo yethu isezingeni elithembekile, inentengo encintisanayo, futhi isekela ukuhlolwa komuntu wesithathu.

| Amandla Okudonsa | Amandla Okukhiqiza | Ukwelulwa | |
| I-ASTM A335 P92 | 90 ksi [620 MPa] min | 64 ksi [440 MPa] min | 20% min (Isikhathi eside) |
I-ASTM A335 icacisa amanani okunwebeka okuncane okubalwe kwe-P92 kokuncipha ngakunye kobukhulu bodonga obuyi-1/32 in. [0.8 mm].
| Ubukhulu Bodonga | Ukuphakama kwe-P92 ngamasentimitha angu-2 noma angu-50 mm | |
| in | mm | I-Longitudinal |
| 0.312 | 8 | 20% iminithi |
| 0.281 | 7.2 | 19% iminithi |
| 0.250 | 6.4 | 18% iminithi |
| 0.219 | 5.6 | 17% iminithi |
| 0.188 | 4.8 | 16% iminithi |

| 0.094 | 2.4 | 13% iminithi |
| 0.062 | 1.6 | 12% iminithi |
Lapho ubukhulu bodonga buphakathi kwamanani amabili angenhla, inani elincane lokwelulwa linqunywa yifomula elandelayo:
E = 32t + 10.00 [E = 1.25t + 10.00]
Kuphi:
E = ukunwebeka ngamasentimitha angu-2 noma angu-50 mm, %, kanye
t = ukujiya kwangempela kwamasampula, ngo. [mm].
Izidingo Zokuqina

| UBrinell | AmaVickers | Rockwell | |
| I-ASTM A335 P92 | Ubuningi be-HBW obungu-250 | Ubuningi be-HV obungu-265 | Umkhawulo we-HRC ongu-25 |
Kumapayipi anobukhulu bodonga obungu-0.200 in. [5.1 mm] noma ngaphezulu, kufanele kusetshenziswe ukuhlolwa kokuqina kweBrinell noma kweRockwell.
Ukuhlolwa kobulukhuni be-Vickers kumele kwenziwe ngokuhambisana ne-Test Method E92.
Ukuhlolwa Kokuthamba
Ukuhlolwa kuzokwenziwa kumasampula athathwe kolunye uhlangothi lombhobho ngokuhambisana nezidingo zeSigaba 20 se-ASTM A999.
Ukuhlolwa Kokugoba
Kumapayipi anobubanzi obudlula i-NPS 25 futhi anesilinganiso sobukhulu bodonga esingu-7.0 noma ngaphansi, kufanele ahlolwe ukugoba esikhundleni sokuhlolwa kokuthamba.
Amasampula okuhlola ukugoba kufanele agobe ekushiseni kwegumbi kuze kufike ku-180° ngaphandle kokuqhekeka ngaphandle kwengxenye egobile.
Umkhiqizi kanye Nesimo
Amapayipi ensimbi e-ASTM A335 P92 kumele enziwe yi-inqubo engenamthungofuthi kufanele kuqedwe ngokushisa noma kubanda, njengoba kuchaziwe.
Ipayipi elingenamthungo liyipayipi elingenazo izingcezu zokushisela. Ezindaweni ezinokushisa okuphezulu kanye nezinomfutho ophezulu, amapayipi angenamthungo angamelana nezingcindezi zangaphakathi eziphakeme kanye namazinga okushisa, anikeze ubuqotho besakhiwo kanye nezakhiwo zemishini, futhi agweme amaphutha angaba khona emithungweni yokushisela.
Ukwelashwa Kokushisa
Ipayipi le-P92 kufanele liphinde lifudumale ukuze liphathwe ngokushisa futhi liphathwe ngokuhambisana nezidingo.
| Ibanga | I-ASTM A335 P92 |
| Uhlobo Lokwelapha Ukushisa | ukwenza ngokwejwayelekile kanye nokushisa |
| Ukulinganisa Izinga Lokushisa | 1900 ~ 1975 ℉ [1040 ~ 1080 ℃] |
| Izinga Lokushisa Elilinganiselayo | 1350 ~ 1470 ℉ [730 ~ 800 ℃] |
Ezinye zezinsimbi ze-ferritic ezimbozwe yile ncazelo zizoqina uma zipholiswa ngokushesha zisuka ngaphezu kwezinga lokushisa lazo elibucayi. Ezinye zizoqina emoyeni, okungukuthi, ziqine ngezinga elingathandeki uma zipholiswa emoyeni zisuka emazingeni okushisa aphezulu.
Ngakho-ke, imisebenzi ehilela ukushisa izinsimbi ezinjalo ngaphezu kwamazinga okushisa abucayi, njengokushisela, ukufulela, kanye nokugoba okushisayo, kufanele ilandelwe ukwelashwa kokushisa okufanele.
