ASTM A335 P91 Umuyoboro wibyuma

Astm A335 ibisobanuro byerekana imiyoboro ya ferritic alloy-ibyuma bya serivisi yubushyuhe bwo hejuru

ASTM A335 isanzwe itangwa mugihe cyagenwe A 335 / A 335M; umubare uhita ukurikira izina ryerekana umwaka wakiriwe mbere cyangwa, mugihe cyo gusubiramo, umwaka wanyuma. Umubare uri mumurongo werekana umwaka wanyuma wemewe. Superscript epsilon (ュ) yerekana impinduka zahinduwe kuva ivugurura ryanyuma cyangwa ryemewe.

Umwanya

1.1Ibi bisobanuro bikubiyemo urukuta rw'izina (ugereranije) urukuta rudafite ibyuma-ibyuma bigenewe serivisi y'ubushyuhe bwo hejuru (Mote 1). Umuyoboro uteganijwe kuri ibi bisobanuro ugomba kuba wunamye, guhindagurika (vanstoning), hamwe nuburyo busa bwo gukora, no gusudira fusion. Guhitamo bizaterwa nigishushanyo, imiterere ya serivisi, imiterere yubukanishi, hamwe nubushyuhe bwo hejuru.

ICYITONDERWA 1 Α Umugereka X1 urutonde rwubunini nubunini bwurukuta rwumuyoboro ushobora kuboneka mubikorwa byubucuruzi.

1.2 Ibyiciro byinshi byibyuma bya ferritic (Icyitonderwa 2) birapfunditswe.

Icyitonderwa 2

Ste Ibyuma bya ferritike muri ibi bisobanuro bisobanurwa nkibyuma bito kandi biciriritse-bivanze birimo kugeza kuri 10 ％ chromium.
1.3 Ibisabwa byiyongera (S1 kugeza S7) byimiterere idahwitse biratangwa. Ibi bisabwa byinyongera bisaba ko hakorwa ibizamini byinyongera, kandi mugihe ubishaka, bigomba kuvugwa murutonde hamwe numubare wibizamini bisabwa.
1.4 Indangagaciro zavuzwe haba muri santimetero-pound cyangwa SI ibice bigomba gufatwa ukundi nkibisanzwe. Mubyanditswe, ibice bya SI byerekanwe mumutwe. Indangagaciro zavuzwe muri buri sisitemu ntabwo zihwanye neza; kubwibyo, buri sisitemu igomba gukoreshwa yigenga iyindi. Guhuza indangagaciro kuva muri sisitemu zombi zishobora kuvamo kudahuza nibisobanuro. Ibice bya pound-pound bizakurikizwa keretse "M" ibisobanuro byiyi ngingo bisobanuwe murutonde.

Icyitonderwa 3ΑUmushushanyo utagira urugero NPS (ubunini bw'umuyoboro w'izina) wasimbuwe muri iki gipimo ku magambo gakondo nka "diameter nominal," "ingano," na "ubunini bw'izina."

Ibikoresho & Gukora

Umuyoboro urashobora kuba ushushe urangiye cyangwa ukonje ushushanyije hamwe no kuvura ubushyuhe bwavuzwe haruguru.

Ikizamini cya Transvers cyangwa Longitudinal Ikizamini na Flattening Ikizamini, Ikizamini gikomeye, cyangwa Ikizamini cya BendIbizamini bya mashini byerekanwe

Ku bushyuhe bwibintu bivurwa mu itanura ryubwoko, ibizamini bizakorwa kuri 5% byumuyoboro uva kuri buri gice cyavuwe. Kubufindo buto, byibuze umuyoboro umwe ugomba kugeragezwa.
Kubushuhe bwibintu bivurwa nuburyo bukomeza, ibizamini bizakorwa kumubare uhagije wumuyoboro ugizwe na 5% yubufindo, ariko ntakibazo kiri munsi ya 2.

Icyitonderwa cyikizamini gikomeye:
P91 ntigomba kugira ubukana butarenze 250 HB / 265 HV [25HRC].

Inyandiko zo Kwipimisha:
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.
Indi miyoboro ifite diameter ingana cyangwa irenga NPS 10 irashobora guhabwa ikizamini cyo kugunama mu mwanya wikizamini gisibanganye byemejwe nuwaguze.
Ikigereranyo cyikizamini kigoramye kigomba kuba cyunamye mubushyuhe bwicyumba kugeza 180 bitavunitse hanze yikigice.

Ikizamini cya Hydrostatike

Imbere ya diameter yimbere igomba kuba ifite santimetero 25.
Buri burebure bwumuyoboro bugomba kuba Hydro igeragezwa, mugihe cyo gukora ibizamini byamashanyarazi bidashobora gukoreshwa.
