ASTM A333 Icyiciro cya 6 Umuyoboro - BLOG

Incamake yubuhanga

ASTM A333 Icyiciro cya 6 gikubiyemo imiyoboro y'icyuma idafite ubudodo kandi isudira ikoreshwa ku bushyuhe buke kugeza kuri dogere 50 F (–46 dogere).

Icyuma cyakozwe kugirango kigumane ubukana mu bihe bya subzero, gishyigikira gukumira umutekano muke hamwe n’imiterere ihamye mu gusaba sisitemu zo mu bwoko bwa kirogenike nka terefone ya LNG, inganda zitunganya gaze, n’ibikorwa remezo by’imiyoboro ya arctique.

Ibikorwa by'ingenzi biranga:

Kurwanya kumeneka munsi yubushyuhe bwumuriro
Imbaraga zihamye mugihe cyo gutangira ubukonje
Weldability yizewe yo gushiraho umurima
Yubahiriza ubushyuhe buke - ubushyuhe bwa sisitemu ya ASME

Ibigize imiti

Ikintu	Ibisabwa (wt%)	Imikorere y'ubwubatsi
Carbone (C)	Ntabwo ari munsi cyangwa bingana na 0.30	Imbaraga vs kuringaniza
Manganese (Mn)	0.29 – 1.06	Yongera ubukana n'ubunyangamugayo
Fosifore (P)	Ntabwo ari munsi cyangwa bingana na 0.025	Kugabanya kuvunika
Amazi (S)	Ntabwo ari munsi cyangwa bingana na 0.025	Itezimbere neza
Silicon (Si)	0.10 – 0.35	Deoxidation & stabilite structure

Amazi meza ya sulfure na fosifore biteza imbere ubukonje bukabije.

Ibikoresho bya mashini

Umutungo	Ibisabwa	Inyungu ya Cryogenic
Imbaraga	Biruta cyangwa bingana na 415 MPa (60 ksi)	Umutekano wibikoresho byumutekano
Gutanga Imbaraga	Biruta cyangwa bingana na MPa 240 (35 ksi)	Kugenzura guhindura no kwizerwa
Kurambura	Kurenza cyangwa bingana na 30%	Plastike iri munsi yo gutwara cyangwa kugunama
Ikizamini Ingaruka	Impamyabumenyi ya 50 F (–46 dogere), ni itegeko	Irinda kuvunika kuvunika

Charpy V - Igeragezwa ryerekana ko irwanya kuvunika kuri LNG na serivisi ya arctique.

Gukora no Kuvura Ubushyuhe

ASTM A333 Imiyoboro yo mucyiciro cya 6 ikorwa haba idafite icyerekezo cyangwa nk'imiyoboro isudira, ariko muri ibyo bihe byombi inzira yashyizweho kugirango ihuze ubushyuhe buke -. Umusaruro utangirana nicyuma gisukuye, cyiza - kugirango umenye neza ko ibikoresho bishobora gukuramo ingaruka kubushyuhe bwa subzero. Gukora no kugereranya biragenzurwa kugirango umuyoboro ugumane neza OD, urukuta no kugororoka, nibyingenzi mugihe imirongo yabanjirijwe hamwe numurima - gusudira. Ubwiza bwimbere bwimbere nabwo burakurikiranwa kugirango bugumane ibintu byiza biranga peteroli, gaze cyangwa itangazamakuru ryingirakamaro.

Nyuma yo gukora, imiyoboro ishyirwa mubushyuhe bugenzurwa - cycle yo kuvura. Iyi ntambwe ntabwo ari ukugabanya gusa stress - ni cyane cyane kugarura ihindagurika ndetse no hanze ya microstructure kugirango Charpy ingaruka zagaciro kuri dogere - 45 (cyangwa ubushyuhe bwerekanwe murutonde) zishobora kuboneka. Gukora neza cyangwa gutondeka neza gutunganya ingano, kunoza ubukana, kandi bigaha umuyoboro mwiza guhangana ningaruka zitunguranye cyangwa ihindagurika ryumuvuduko mubihe bikonje.

Ibipimo by'imiyoboro & Amahitamo yo gutanga

Parameter	Urwego rusanzwe
Hanze ya Diameter	1/2 "- 48" (21.3 - 1219 mm)
Uburebure bw'urukuta	SCH 20 - SCH XXS cyangwa gakondo
Uburebure	SRL / DRL / Kata - kugeza - Uburebure

Umushinga - kwihanganira byihariye nibisabwa NDE birashobora gushyirwamo mubikorwa bikomeye.

Gusudira no guhimba kuri Cryogenic umuyoboro wuzuye

ASTM A333 Icyiciro cya 6 gitanga ubudasiba buhamye bwo guteranya moderi no kubaka imirima.

Nyamara, ubushyuhe - zone yibasiwe (HAZ) igomba kubikwa neza kugirango harebwe ubushyuhe buke -:

Uburyo bwo gusudirahamwe na SMAW, GTAW, na GMAW kububiko bwombi hamwe nu murima
WPS yujuje ibyangombwa / PQRasabwa kwemeza ingaruka zikomeye nyuma yo gusudira mumirimo ya cryogenic
Kugenzura ubushyuhe bukabijekugirango wirinde guhunika ingano no gutakaza ubukana bwa notch muri HAZ
PWHT ishingiye kumiterere ya serivisino gushushanya code ibisabwa kugirango utezimbere weld ihuriweho
Kugenzura ikidodo (UT / RT)birasabwa kuri LNG hamwe na arctique ya progaramu hamwe ningaruka zo gutsindwa

Uburyo bwiza bwo gusudira bukoreshwa neza bwerekana ko umuyoboro washyizweho ukomeza guhangana no kuvunika no kumeneka - gukora cyane mugihe gikonje cyatangiye.

Kugenzura & Kwipimisha Ibisabwa

Ikizamini	Intego
Hydrostatike / NDE	Kwirinda kumeneka
Ikizamini Ingaruka	Subzero gukomera
Ikizamini	Komeza kubahiriza
Kuringaniza / Kwunama	Isuzumabushobozi
Ikizamini gikomeye	Ubukonje - kurwanya
Ikimenyetso & MTC ikurikirana	QA ubugenzuzi no kubahiriza code

Ikizamini cy'inyongera (PMI / UT 100% / icya gatatu - umutangabuhamya w'ishyaka) kiboneka kubice bikomeye.

Imiyoboro ya Cryogenic na firigo
Amavuta ya Arctique & gazi yohereza
Hasi - ubushyuhe bwumuvuduko & modules
Ibikorwa bikonje byo hanze no ku nkombe - ibikorwa remezo byikirere
Yashizweho kugirango wirinde ingaruka zananiranye ziterwa nubushyuhe bukabije.

Incamake

Umuyoboro wa Octal ushyigikira imiyoboro ya cryogenic hamwe nuburyo bwo gusudira bujuje ibyangombwa, ibyemezo byikizamini byemejwe, hamwe nibishobora gukurikiranwa kuva murusyo kugeza kwishyiriraho.

Kubahiriza - gutanga isoko, kugenzura byabugenewe, no gutanga byizewe bituma ASTM A333 Icyiciro cya 6 kuva Umuyoboro wa Octal wahisemo neza kuri LNG hamwe na - ubushyuhe bwibidukikije.
