Inganda zisanzwe Ubushinwa API 5L 5CT Psl1 / Psl2 X42 / X52 / X46 / X56 / X60 / X65 / X70 / X80 Imiyoboro y'icyuma idafite umurongo
Incamake
Kugira ngo tubone ibisubizo byihariye no gusana ubwenge, isosiyete yacu yatsindiye izina ryiza mubakiriya ku isi yose kuri API 5L 5CT Psl1 / Psl2 X42 / X52 / X46 / X56 / X60 / X65 / X70 / X80 Icyuma kitagira umurongo. Imiyoboro, Dushishikarizwa nisoko ryihuta ryisoko ryubu kubiribwa byihuse nibiribwa byibinyobwa kwisi yose, Turimo guhiga gukorana nabafatanyabikorwa / abakiriya kugirango tubone ibisubizo byiza hamwe. Twagiye dukora tekinolojiya mishya yo koroshya umusaruro, no gutanga ibicuruzwa nibiciro byapiganwa kandi bifite ireme! Guhaza abakiriya nibyo dushyira imbere! Urashobora kutwemerera kumenya igitekerezo cyawe cyo guteza imbere igishushanyo cyihariye cya moderi yawe bwite kugirango wirinde ibice bisa cyane ku isoko! Tugiye kuguha serivisi nziza kugirango uhaze ibyo ukeneye byose! Nyamuneka twandikire ako kanya!
Umuyoboro w'imiyoboro: amavuta, gaze cyangwa amazi yakuwe mu butaka ajyanwa mu nganda za peteroli na gaze n'umuyoboro w'imiyoboro. Umuyoboro w'imiyoboro ugizwe n'ubwoko bubiri bw'imiyoboro idafite ubudodo kandi isudira, impera y'umuyoboro ifite impera iringaniye, impera y'urudodo na a iherezo rya sock; Uburyo bwo guhuza ni impera yo gusudira, guhuza amakariso, guhuza sock nibindi.
Umuyoboro w'imiyoboro: amavuta, gaze cyangwa amazi yakuwe mu butaka ajyanwa mu nganda za peteroli na gaze n'umuyoboro w'imiyoboro. Umuyoboro usudira uhujwe n'umuyoboro wo gusudira wahujwe, muri rusange uburebure ni burebure, burashobora guhaza ubwinshi bw'abakoresha, ariko gutekana ntabwo aribyiza nkuburyo bumwe bwahujwe bwumuyoboro utagira ikizinga, ariko muri rusange ni ngufi uburebure bwumuyoboro utagira kashe, ntibishobora guhaza umuguzi gukoresha intera ndende, umuguzi arakoresha inzira akeneye gukora collocation ikoreshwa byombi.Umuyoboro wumuyoboro urimo ubwoko bubiri bwumuyoboro udasobekeranye kandi wasuditswe, umuyoboro wumuyoboro ufite impera iringaniye, impera yumutwe hamwe nu musozo wa sock; Uburyo bwo guhuza ni impera yo gusudira, guhuza amakariso, guhuza sock nibindi.
Hamwe niterambere ryiterambere rya tekinoroji yicyuma hamwe niterambere ryogukora imiyoboro isudira, tekinoroji yo gusudira, urwego rwo gukoresha imiyoboro hamwe numuyoboro wasudutse mukugenda waguka buhoro buhoro, cyane cyane mumurambararo munini wa diametre weld wapanze ibyiciro byinyungu nyinshi, nigiciro ibintu, umuyoboro usudira wiganje mu bijyanye n'umuyoboro w'umurongo, ugabanya iterambere ry'icyuma kitagira umuyonga.
Umuyoboro wa API5L urimo gukoresha uburyo bwo gutunganya ubushyuhe bwa microalloying, igiciro cyumusaruro wicyuma udafite ingese kiri hejuru cyane ugereranije numuyoboro wasuditswe, kandi hamwe no kuzamura urwego rwicyuma, nkumuyoboro wicyuma cya X80 kurwego rwa karuboni ihwanye, inzira isanzwe y'icyuma kitagira icyuma kiragoye kubahiriza ibyo ukoresha asabwa
Umuyoboro wogukwirakwiza ugabanijwemo PSL1, PSL2 ibyiciro bibiri byibicuruzwa, itandukaniro nyamukuru nuko PSL2 ugereranije na PSL1 ihwanye na karubone ihwanye, gukomera kuvunika, imbaraga nyinshi zumusaruro hamwe nimbaraga nyinshi zisabwa.Gucunga ibintu byangiza nka fosifore na sulferi nabyo gukomera.Igeragezwa ridasubirwaho rya tebes idafite uburinganire ni itegeko. Ibiri muri garanti hamwe nibishobora gukurikiranwa nyuma yubushakashatsi ni itegeko.
Ibikorwa byingenzi bisabwa mu miyoboro ya peteroli na gaze ku byuma birimo:
1. Imbaraga: Umuyoboro rusange wa peteroli na gaze wakozwe ukurikije imbaraga zumusaruro wibyuma. Imiyoboro ifite imbaraga nyinshi zishobora kwihanganira umuvuduko mwinshi wakazi.
2. n'umuyoboro w'icyuma ugomba kuba wipimishije mbere yo kuva muruganda.
D. n'ahantu hibasiwe n'ubushyuhe, kandi byongere amahirwe yo guturika kw'imiyoboro. Ihame ry'igishushanyo cyo gusudira ibyuma ni ukugenzura aho inzibacyuho ya martensite no gukomera. Ukurikije ingaruka z'ibintu bivangavanze kuri martensite y'inzibacyuho n'uburambe bufatika, formula yo kubara ya ibingana na karubone birashobora gukoreshwa mugusuzuma gusudira kwicyuma.Muri rusange, ibingana na karubone bigomba kugenzurwa munsi ya 0.4%. Mubyukuri, inganda nyinshi zicyuma zigenzurwa munsi ya 0.35%.
4 ikizamini cyo gukonjesha gukonje.Urufunguzo rwo kunoza ihindagurika ni ukugabanya ibyuma bitari ibyuma mubyuma no kugenzura morphologie no gukwirakwiza ibiyirimo.
5. muri rusange byemewe.Ibintu nyamukuru biranga ni microalloying kandi igenzurwa, ishobora kubona imbaraga nyinshi, ubukana bwinshi, plastike nyinshi hamwe no gusudira neza mugihe gishyushye.Mu rwego rwo kuzuza byuzuye ibisabwa mumiyoboro ya peteroli na gaze kubyuma, igishushanyo mbonera gikomeye , sulfure, fosifore nibindi bintu byangiza nabyo biragenzurwa cyane.Muri rusange, sulferi iri munsi ya 0.01% kugirango itezimbere plastike nubukomezi bwibyuma, cyane cyane gukomera kwa transvers.
Gusaba
Umuyoboro ukoreshwa mu gutwara peteroli, amavuta n'amazi yavomwe mu butaka mu nganda zikomoka kuri peteroli na gaze binyuze mu muyoboro

Nta gucika kugaragara mugice icyo aricyo cyose cyikizamini kandi nta gufungura gusudira kuzabaho.
Ikizamini
Ibipimo byo kwemererwa gukora ikizamini giteganijwe ni:
- Imiyoboro ya EW D <12.750 muri:

- Ku muyoboro ufite D / t> 10, ntihazabaho gufungura gusudira mbere yuko intera iri hagati yisahani iri munsi ya 30% yumwimerere wa diameter.
- Kubindi bipimo reba ibisobanuro byuzuye bya API 5L.
Ikizamini cya CVN kuri PSL2
Ingano nini ya PSL2 nini hamwe n amanota bisaba CVN. Umuyoboro utagira ikizinga ugomba gupimwa mumubiri. Umuyoboro wo gusudira ugomba gupimwa mumubiri, gusudira imiyoboro hamwe na zone yibasiwe nubushyuhe. Reba kuri API 5L yuzuye ibisobanuro ku mbonerahamwe yubunini n'amanota kandi bisabwa imbaraga zingirakamaro.
