Kodi ASTM A335 P92 ndi chiyani?

ASTM A335 P92 (ASME SA335 P92) ndi chitoliro chachitsulo chopanda msoko chomwe chimapangidwira kutentha kwambiri.UNS imadziwika kuti K92460.

P92 ndi chitsulo cha alloy cholimba kwambiri chomwe chili ndi chromium martensitic yolimba komanso yosatentha chomwe chili ndi 8.50–9.50% chromium ndipo chimaphatikizidwa ndi Mo, W, V, ndi Nb, chomwe chimapereka mphamvu yabwino kwambiri yokwera kutentha, kukana okosijeni, komanso kukana kutopa ndi kutentha.

Amagwiritsidwa ntchito kwambiri m'mizere yayikulu ya nthunzi, m'mizere yotenthetsera nthunzi, m'machubu otenthetsera ndi otenthetsera a ma boiler amphamvu ofunikira kwambiri komanso ofunikira kwambiri, komanso m'mapaipi otenthetsera ndi opanikizika kwambiri komanso m'zigawo zofunika kwambiri zosungira kupanikizika m'malo opangira mafuta ndi oyeretsera.

Zambiri zaife

Botop Steel ndi kampani yodziwika bwino komanso yodalirika yogulitsa mapaipi achitsulo cha alloy komanso yogulitsa zinthu zambiri ku China, yomwe imatha kupereka mwachangu mapulojekiti anu mapaipi achitsulo cha alloy osiyanasiyana, kuphatikizaP5 (K41545), P9 (K90941), P11 (K11597), P12 (K11562), P22 (K21590)ndiP91 (K90901).

Zogulitsa zathu ndi zapamwamba kwambiri, zimakhala ndi mitengo yopikisana, ndipo zimathandiza kuyang'aniridwa ndi anthu ena.

Mawu akuti Nb (Niobium) ndi Cb (Columbium) ndi mayina ena a chinthu chomwecho.

Katundu wa Makina

Katundu Wokoka

Giredi	Katundu Wokoka
Giredi	Kulimba kwamakokedwe	Mphamvu Yopereka	Kutalikitsa
ASTM A335 P92	90 ksi [620 MPa] mphindi	64 ksi [440 MPa] mphindi	Mphindi 20% (Yaitali)

ASTM A335 imatchula kuchuluka kocheperako koyezera kwa P92 pa kuchepa kulikonse kwa makulidwe a khoma kwa 1/32 inchi [0.8 mm].

Kukhuthala kwa Khoma		Kutalikirana kwa P92 mu mainchesi awiri kapena 50 mm
in	mm	Longitudinal
0.312	8	Mphindi 20%
0.281	7.2	Mphindi 19%
0.250	6.4	Mphindi 18%
0.219	5.6	Mphindi 17%
0.188	4.8	Mphindi 16%
0.156	4	Mphindi 15%
0.125	3.2	Mphindi 14%
0.094	2.4	Mphindi 13%
0.062	1.6	Mphindi 12%

Pamene makulidwe a khoma ali pakati pa mfundo ziwiri pamwambapa, mtengo wocheperako wa kutalika umatsimikiziridwa ndi njira yotsatirayi:

E = 32t + 10.00 [E = 1.25t + 10.00]

Kumene:

E = kutalika kwa mainchesi awiri kapena 50 mm, %, ndi

t = makulidwe enieni a zitsanzo, mu. [mm].

Zofunikira pa Kuuma

Giredi	Katundu Wokoka
Giredi	Brinell	Vickers	Rockwell
ASTM A335 P92	250 HBW payokha	Mphamvu yapamwamba kwambiri ya 265 HV	25 HRC payokha

Pa mapaipi okhala ndi makulidwe a khoma a mainchesi 0.200 [5.1 mm] kapena kupitirira apo, mayeso olimba a Brinell kapena Rockwell ayenera kugwiritsidwa ntchito.

Kuyesa kuuma kwa Vickers kuyenera kuchitidwa motsatira Njira Yoyesera E92.

Mayeso Ophwanyika

Mayesowa ayenera kuchitidwa pa zitsanzo zomwe zatengedwa kuchokera kumapeto kwa chitolirocho motsatira zofunikira za Gawo 20 la ASTM A999.

Mayeso Opindika

Pa chitoliro chomwe mainchesi ake ndi oposa NPS 25 ndipo chiŵerengero chake cha mainchesi ndi makulidwe a khoma ndi 7.0 kapena kuchepera, chiyenera kuyesedwa kupindika m'malo mwa mayeso ophwanyika.

Zitsanzo zoyeserera kupindika ziyenera kupindika kutentha kwa chipinda mpaka madigiri 180 popanda kusweka kunja kwa gawo lopindika.

Kupanga ndi Kutentha

Wopanga ndi Mkhalidwe

Mapaipi achitsulo a ASTM A335 P92 ayenera kupangidwa ndinjira yopanda msokondipo iyenera kumalizidwa kutentha kapena kuzizira, monga momwe zafotokozedwera.

Chitoliro chopanda msoko ndi chitoliro chopanda ma weld. M'malo otentha kwambiri komanso opanikizika kwambiri, mawayilesi opanda msoko amatha kupirira kupsinjika kwakukulu kwamkati ndi kutentha, kupereka umphumphu wabwino komanso mawonekedwe abwino a makina, ndikupewa zolakwika zomwe zingachitike pa ma weld seams.

Kutentha Chithandizo

Chitoliro cha P92 chiyenera kutenthedwanso kuti chitenthedwe ndikukonzedwa motsatira zofunikira.

Giredi	ASTM A335 P92
Mtundu Wothandizira Kutentha	kusinthasintha ndi kusinthasintha
Kutentha Koyenera	1900 ~ 1975 ℉ [1040 ~ 1080 ℃]
Kutentha Kotentha	1350 ~ 1470 ℉ [730 ~ 800 ℃]

Zitsulo zina za ferritic zomwe zili mu izi zidzalimba ngati zitazizidwa mofulumira kuchokera pamwamba pa kutentha kwawo kofunikira. Zina zidzalimba mpweya, kutanthauza kuti, zidzalimba kwambiri zikaziziritsidwa mu mpweya kuchokera kutentha kwambiri.

Chifukwa chake, ntchito zokhudzana ndi kutentha zitsulo zotere kuposa kutentha kwake kofunikira, monga kuwotcherera, kupalasa, ndi kupindika kutentha, ziyenera kutsatiridwa ndi chithandizo choyenera cha kutentha.
