ASTM A335 P5, bizwi kandi nka ASME SA335 P5, ni umuyoboro muke muto utagira icyuma ugenewe serivisi yubushyuhe bwo hejuru.
P5 irimo chromium 4.00 ~ 6.00% na 0.45 ~ 0,65% molybdenum, itanga imbaraga nziza nibikorwa munsi yubushyuhe bwinshi nubushyuhe. Ikoreshwa cyane mubikoresho nka boiler, superheater, hamwe no guhanahana ubushyuhe.
Izina ryayo UNS ni K41545.
Ihinguriro n'imiterere
ASTM A335 P5 imiyoboro yicyuma igomba gukorwa nuburyo butagira ikizinga kandi igomba kuba ishyushye irangiye cyangwa ikonje ikonje, nkuko byavuzwe.
Imiyoboro ishyushye irangiye ni imiyoboro yicyuma idafite kashe ikozwe mumatike binyuze mu gushyushya no kuzunguruka, mugihe imiyoboro ikururwa n'imbeho ari imiyoboro y'icyuma idafite kashe ikorwa no gushushanya imiyoboro ishyushye ku bushyuhe bw'icyumba.
Niba wifuza kumenya byinshi kubyerekeranye nuburyo bwo gukora ubu bwoko bubiri bwimiyoboro idafite ibyuma, urashobora gukanda“Umuyoboro w'icyuma utagira ikizinga ni iki?”kubindi bisobanuro.
Kuvura Ubushuhe
Imiyoboro ya ASTM A335 P5 igomba gushyuha kugirango ivure ubushyuhe nubushyuhe buvurwabyuzuye cyangwa isothermal annealing or gusanzwe no kurakara.
Ibisabwa byihariye bigaragara mu mbonerahamwe ikurikira:
| Icyiciro | Ubwoko bwo kuvura ubushyuhe | Subcritical Annealing cyangwa Ubushyuhe |
| ASTM A335 P5 | byuzuye cyangwa isothermal anneal | - |
| gusanzwe no kurakara | 1250 ℉ [675 ℃] min |
Ibikorwa birimo gushyushya imiyoboro yicyuma hejuru yubushyuhe bwabo bukomeye, nko gusudira, guhindagurika, no kugonda ubushyuhe, bigomba gukurikizwa no kuvura ubushyuhe bukwiye.
Uburyo bwo gupima imiterere yimiti nubukanishi bwimiyoboro ya P5 igomba kubahiriza ingingo zijyanye na ASTM A999.
| Icyiciro | Ibigize,% | ||||||
| C | Mn | P | S | Si | Cr | Mo | |
| P5 | 0.15 max | 0.30 ~ 0.60 | 0.025 max | 0.025 max | 0,50 max | 4.00 ~ 6.00 | 0.45 ~ 0.65 |
Ibintu byiza
| Icyiciro | Imbaraga | Gutanga Imbaraga | Kurambura muri 2 muri. cyangwa mm 50 |
| P5 | 60 ksi [415 MPa] min | 30 ksi [205 MPa] min | 30% min |
Ibyiza byo gukomera
Ibipimo bya ASTM A335 ntibisobanura ibikenewe byose kugirango imiyoboro ya P5 yicyuma.
Ikizamini cya Flattening
Ikizamini cya Flattening kizakorwa kandi gitangwe hakurikijwe ibisabwa bijyanye na ASTM A999, kandi imiyoboro ihanamye ishobora gukoreshwa nkurugero.
Ikizamini
Ku muyoboro ufite diameter irenze NPS 25 kandi umurambararo wa diametre ku kigero cy’uburebure bwa 7.0 cyangwa munsi yayo ugomba gukorerwa ikizamini cyunamye aho kuba ikizamini cyo gusibanganya.
Ikigereranyo cyo kugoreka kigomba kugororwa ku bushyuhe bwicyumba kugeza kuri 180 ° bitavunitse hanze y igice cyagoramye. Imbere ya diameter yimbere igomba kuba 1 muri. [25 mm].
Kugaragara
Ubuso bw'umuyoboro w'icyuma bugomba kuba bworoshye kandi buringaniye, butarimo ibisebe, ubudodo, ibibero, amarira, cyangwa amashanyarazi.
Niba ubujyakuzimu bw'inenge iyo ari yo yose burenze 12.5% by'uburebure bw'urukuta rw'izina cyangwa niba uburebure bw'urukuta busigaye buri munsi y'uburebure bwagenwe, agace kazafatwa nk'inenge.
Iyo uburebure bwurukuta rusigaye bukiri mumipaka yagenwe, inenge irashobora gukurwaho no gusya.
Niba uburebure bwurukuta rusigaye buri munsi yicyifuzo gisabwa, inenge igomba gusanwa no gusudira cyangwa gukurwaho no gukata.
Ubworoherane bwa Diameter
Ku miyoboro yatumijwe na NPS [DN] cyangwa diameter yo hanze, itandukaniro rya diameter yo hanze ntirishobora kurenga ibisabwa bigaragara kumeza ikurikira:
| NPS [DN] Ibishushanyo | Impinduka zemewe | |
| in. | mm | |
| 1/8 kugeza 1/2 [6 kugeza 40], santimetero. | ± 1/64 [0.015] | ± 0.40 |
| Kurenga 1/2 kugeza 4 [40 kugeza 100], santimetero. | ± 32 [0.031] | ± 0.79 |
| Kurenga 4 kugeza 8 [100 kugeza 200], santimetero. | -1/32 - +1/16 [-0.031 - +0.062] | -0.79 - +1.59 |
| Kurenga 8 kugeza 12 [200 kugeza 300], santimetero. | -1/32 - +3/32 [-0.031 - 0.093] | -0.79 - +2.38 |
| Kurenga 12 [300] | ± 1% byerekanwe hanze ya diameter | |
Ku muyoboro wateganijwe imbere ya diameter, imbere imbere ntishobora gutandukana kurenza 1% uhereye kumurambararo wimbere.
Ubworoherane bw'urukuta
Usibye kugarukira ku buryo butaziguye uburebure bw'urukuta ku muyoboro washyizweho no kugabanya uburemere muri ASTM A999, uburebure bw'urukuta rw'umuyoboro aho ariho hose bugomba kuba mu kwihanganira kugaragara ku mbonerahamwe ikurikira:
| NPS [DN] Ibishushanyo | Ubworoherane,% Ifishi Yerekanwe |
| 1/8 kugeza 2 1/2 [6 kugeza 65] incl. ibipimo byose t / D. | -12.5 - +20.0 |
| Hejuru ya 2 1/2 [65], t / D ≤ 5% | -12.5 - +22.5 |
| Hejuru ya 2 1/2, t / D ＞ 5% | -12.5 - +15.0 |
| t = Uburebure bwurukuta; D = Kugaragara Hanze ya Diameter. | |
