API 5L X65 Umuyoboro wasizwe

Mu muryango wa API 5L,X65ihitamo cyane mugihe abashushanya bashaka umuvuduko mwinshi wo gukora hamwe nigihe kirekire -, ariko bagakenera amanota ashobora gusudwa no gushyirwaho neza kurubuga. Irasobanuwe cyane kumirongo ya peteroli na gaze, imiyoboro yohereza ibicuruzwa hanze, imiyoboro ya gaze mukarere hamwe na - imitwe ya sitasiyo yumuvuduko aho X52 / X60 ifatana cyane kurukuta check- kugenzura ubugari, mugihe X70 / X80 yakongeramo ibikoresho bitari ngombwa no gusudira bigoye.

X65 imaze gutorwa, icyemezo gikurikira nubusanzweifishi y'ibicuruzwa: ERW / HFW, LSAW / SAWL cyangwa SSAW / SAWH. Ihitamo riterwa nuburyo umurongo uzubakwa - ugororotse ku nkombe ikwirakwira, umuhanda / kwambuka imigezi, ubutayu - amazi S - kurambika cyangwa kwimbitse - amazi J - lay - no kuri sisitemu yo gutwikira hanze n’imbere ikenewe muri serivisi.

UrwegoX65isobanuwe muriAPI 5L(Byahujwe naISO 3183), igipimo nyamukuru cyumuyoboro utagira umurongo kandi usudira ukoreshwa muri sisitemu yo gutwara imiyoboro yinganda za peteroli na gaze. Ibimenyetso nka "X65M" cyangwa "X65Q" byerekana urwego rwimbaraga nuburyo bwo gutanga:

• X65 (PSL1)- icyiciro cy'umurongo w'icyiciro
• X65M (PSL2)- thermo - yatunganijwe, yongerewe imbaraga
• X65Q (PSL2)- kuzimya no kwitonda kuri serivisi isaba cyane

Kubice byinzira bifatwa nkibyingenzi - nkibidukikije byangiza ibidukikije kandiserivisi zo hanzeimirongo yohereza hanze - ibisobanuro bisanzwe bisabaPSL2 X65kuberako igenzura rikomeye rya chimie, ibizamini byingutu byateganijwe hamwe nibisobanuro birambuye. X65 idafite ubuzimagatozi yemerewe nibisanzwe, ariko binini - diametre nuburebure - imiyoboro ya interineti ikunze guhitamogusudira X65kuringaniza ubushobozi, gusudira ubuziranenge nigiciro cyumushinga.

Muri sisitemu ya API 5L,X65bihuye nimbaraga ntarengwa yumusaruro (SMYS) ya65.000 psi (≈ 450 MPa). Agaciro kajya mu rukuta - uburebure hamwe na formulaire ya ASME B31.4, B31.8 hamwe na code zisa.

Imbonerahamwe 1 - Ibikoresho bisanzwe byibuze (ibikoresho):

Mubishushanyo mbonera, SMYS igwizwa nibintu byashushanyije kugirango itange impagarara zemewe, hanyuma ibi bigashyiraho igitutu kinini cyo gukora.SMTSitanga intera yinyongera kunanirwa byanyuma mugihe umuvuduko wimbere uhujwe no kunama, ingaruka zubushyuhe hamwe nuburemere bwo hanze.Kuramburani ngombwa mugihe cyo kubaka no gukora, kuko byerekana uburyo umuyoboro ushobora kwihanganira kugonda umurima, guhambira - ins, gusubira inyuma hamwe nigihe kirekire - kwimuka kubutaka bitavunitse.

Kuri PSL2 X65, inyandiko z'umushinga zikunze kwerekanaCharpy V - icyiciro cyibizaminiku bushyuhe bwasobanuwe, kandi, kurukuta rwinshi cyangwa hasi - imirongo yubushyuhe,DWTT.

Kugirango ugere kuri X65 imbaraga utarinze gusudira bigoye cyane, amanota ashingira kuri chimie iringaniye aho kuba ibintu byinshi cyane. Ibintu bya karubone, manganese na microalloying byahinduwe hamwe kugirango bihuze imbaraga nintego zikomeye, mugihe fosifore na sulferi bigarukira kurinda imikorere ya weld na HAZ.

Imbonerahamwe 2 - Ibisanzwe bisanzwe bigizwe na X65 umurongo wasizwe (indangagaciro):

Duhereye ku buhanga:

• Carbone (C)itanga imbaraga zifatizo ariko igomba kubikwa kurwego rutuma karubone ihwanye (CE) ibereye gusudira.
• Manganese (Mn)ishyigikira imbaraga zombi kandi hasi - ubukana bukabije.
• Fosifore (P) na sulfuru (S)bagabanutse muri PSL2 kugirango bagabanye imyitwarire idahwitse, cyane cyane hafi ya weld na HAZ.
• Niobium, vanadium na titanium (Nb / V / Ti)ku rugero ruto rutunganya ingano kandi zifasha kuzuza ibisabwa kugirango imishinga isabe byinshi.

Kubice bikonje cyangwa serivise zo mumazi mumazi yubushyuhe cyangwa hasi -, ibisobanuro byumushinga birashobora gushyiraho imipaka ikarishye kuri CE hamwe na microalloy yose kugirango itange amafaranga yinyongera yo gusudira no kuvunika.

Mu bikorwa byumushinga, ikiganiro ntabwo kijyanye na abstract "X65 ibyuma", ahubwo niUmuyoboro wa X65 wakozwe nuburyo bwihariye, buri kimwe gifite umurambararo wacyo, urukuta - ubushobozi bwubunini nuburyo bwigiciro.
