ASTM A106 Umuyoboro udafite kashe

ASTM A106 ni umuyoboro usanzwe wa karubone ibyuma bidafite icyerekezo benshi bagaragaza igihe umurongo ugomba gutwara amazi ashyushye cyangwa gaze munsi yigitutu. Ikozwe murwego rwo hejuru service- serivisi yubushyuhe, irapimwa hakurikijwe ASME B36.10M, kandi irashobora gutangwa nimpera zoroshye cyangwa zometseho gusudira, kunama no guhindagurika. Mu byiciro A, B na C muri ASTM A106, Icyiciro B gikoreshwa cyane kuko gitanga uruvange rwizewe rwimbaraga, guhindagurika no gusudira kumurongo wamazi, imitwe yinganda, imiyoboro itunganya amashanyarazi hamwe ninganda zamashanyarazi.

• Bisanzwe: ASTM A106 / ASME SA106
• Icyiciro: B (nayo iraboneka A, C niba umushinga ubyemerera)
• Ifishi: Nta shiti, ishyushye - yarangije cyangwa imbeho - yarangije
• Iherezo: Impera yikibaya (PE) cyangwa impera (BE) yo gusudira
• Ibipimo: ASME B36.10M, NPS na gahunda - ishingiye

Urwego rushingiye kubintu byoroshye, neza - bigenzurwa na karubone - manganese - silicon. Kugenzura P na S bituma umuyoboro usudira kandi ukomeye.

Impamvu ibi bifite akamaro: karubone itanga urwego imbaraga zifatizo; manganese ifasha guhagarika imiterere ya ferrite - pearlite kandi igateza imbere ubukana; silicon itezimbere igipimo / okiside iyo umuyoboro utwaye amavuta ashyushye cyangwa itangazamakuru ritunganya.

Icyiciro B nicyiciro "cyo hagati" ariko kimaze gukomera bihagije kubikorwa byinshi byibimera.

Ibisobanuro byo gushushanya no guhimba: imbaraga zingana zirinda guturika no kwikorera imitwaro; imbaraga zitanga umusaruro nimbibi mbere yoguhindura burundu, cyane cyane kubyingenzi - umuvuduko ukabije; kurambura byemeza ko umuyoboro ushobora kuba umurima - wunamye, gusudira no gushyirwaho nta gucika.

Imikorere muri High {{0} Service Serivisi y'Ubushyuhe
A106 Icyiciro B kigenewe kuguma muri serivisi ku bushyuhe bwicyuma hafi ya dogere 400-450. Kuri uru rwego microstructure ya ferrite - pearlite ikomeza kuba itajegajega, silikoni ifasha ubuso kurwanya igipimo, kandi umuyoboro ukomeza umuvuduko wacyo -. Niyo mpamvu hasobanuwe imirongo yo kugaburira ibyuka, imitwe ya parike, ubushyuhe - imiyoboro ihinduranya, serivisi zamavuta ashyushye hamwe na sisitemu yingirakamaro. Hamwe nuburyo bukwiye bwa PWHT no gusudira, umuyoboro urashobora kandi gukora muri serivisi ya cycle nta gutakaza vuba gukomera.

Kuri A106 Icyiciro B inzira yo gukora ntabwo ari ibikoresho - niyo mpamvu umuyoboro ushobora gukora mubushyuhe bwinshi nigitutu. Inzira isanzwe y'urusyo kuri A106 Icyiciro cya B kuri Octal Pipe isa nkiyi:

1. Guhitamo bilet no kugenzura imiti
Umusaruro utangirira ku kwicwa (deoxidiside yuzuye), nziza - ingano ya karubone ibyuma bya karubone isanzwe yujuje imiti ya A106. Ibi byemeza P na S nkeya, isuku nziza no gusudira. Ubushyuhe bugenzurwa mbere yo kuzunguruka kugirango intego za mashini zo mu cyiciro cya B zishobora kugerwaho nyuma yo gukora no kuvura ubushyuhe.

2. Gushyushya fagitire
Bilet zishyushye mubizunguruka cyangwa kugenda - itanura ryibiti kugeza ubushyuhe / kuzunguruka. Gushyushya kimwe ni ngombwa hano kuko ubushyuhe butaringaniye bwatera urukuta - uburebure bwimbitse mugihe bilet yatobotse.

3. Gutobora bishyushye (gukora ubusa)
Bilet ishyushye yatobowe kumusaraba - umuzingo cyangwa urusyo rwa mandel kugirango rukore igikonjo. Aha niho umuyoboro uhinduka uva muruziga rukomeye ugahinduka umuyoboro utagira ikizinga. Ikigamijwe ni ugukora igikonoshwa kitagira hagati cyaturika ndetse hamwe nurukuta ruzengurutse umuzenguruko.

4. Kurambura no gucomeka / kuzunguruka
Igikonoshwa cyimbere noneho kirambuye kandi kizunguruka hejuru ya mandel cyangwa imashini icomeka kugirango igere hafi ya diameter yateganijwe hamwe nubunini bwurukuta. Ibirindiro byinshi bizunguruka birashobora gukoreshwa mugutunganya urukuta no kunoza ubuso. Iyi ntambwe ni urufunguzo rwo gukora imbere yimbere no kugumana uburebure bwurukuta mu kwihanganira.

5. Kuringaniza / kugabanya urusyo
Ingano nini cyangwa kugabanya urusyo ruzana umuyoboro kuri OD yanyuma no kuzenguruka. Kuri gahunda ndende (urukuta runini), ibipimo bizunguruka byahinduwe kugirango bikomeze kwibanda. Ingano nyayo hano isobanura gusudira byoroshye kandi bikwiye - hejuru kurubuga.

6. Gukonjesha no kugorora
Nyuma yo gukora bishyushye, imiyoboro ikonjeshwa muburyo bugenzurwa hanyuma ikanyuzwa mumashini igorora. Kugororoka ni ngombwa kubintu byateguwe mbere no gusudira byikora.

7. Kuvura ubushyuhe (nkuko bisabwa)
Ukurikije ingano ya pipe, igipimo cyo kugabanya nibisabwa nabaguzi, imiyoboro irashobora kuba ibisanzwe cyangwa guhangayika - byoroheje.

Ubusanzwe butunganya ferrite - pearlite imiterere, ndetse ikanatanga imitungo muburebure kandi igateza imbere gukomera.

Kuruhuka kwa Stress bivanaho guhangayika, bifite akamaro niba umuyoboro uza gusudira muri sisitemu izabona nyuma yo gusiganwa ku magare.
Ubu buryo bwo kuvura ubushyuhe bugenzurwa nicyo gifasha A106 Icyiciro B gukomeza guhindagurika no kurwanya ingaruka muri serivisi zishyushye.

8. Kurangiza, NDE na hydrotest
Imiyoboro yarangiye yaciwe kuburebure, impera zireba / zishushanyije, kandi buri burebure bugenzurwa muburyo bugaragara kandi buringaniye. Hanyuma umuyoboro urageragezwa:

• ikizamini cya hydrostatike kugirango kigaragaze ko kirimo umuvuduko
• eddy - igezweho cyangwa ultrasonic NDE kugirango ushakishe inenge imbere / hejuru
• gushira akamenyetso hamwe no gutwikira / varnish kugirango ukingire
• Gusa nyuma yizi ntambwe zose ni umuyoboro urekurwa hamwe na MTC.

Kubera ko inzira yose idafite ikidodo (nta welditudinal weld), umuyoboro ufite imbaraga zo kurwanya umuvuduko ukikije umuzenguruko wose - impamvu nyamukuru A106 ihitamo hejuru y'umuyoboro usudira kugirango serivisi yubushyuhe bwo hejuru -.

(ibintu bisanzwe, birashobora gukurikiza icyifuzo cyumushinga)

Kugira ngo umuyoboro wemerwe nigitutu na serivisi zishyushye, ASTM A106 bivuga ibisabwa muri ASTM A999. Umuyoboro wa Octal urashobora gutanga inzira yuzuye yo kugerageza:

• Ikizamini cya Hydrostatike kuri buri burebure kugirango kigaragaze ko kirimo umuvuduko
• Ikizamini kidahwitse (eddy iriho cyangwa ultrasonic) kugirango ugaragaze ubuso nudukosa twimbere
• Ikizamini gikomeye kandi gikomeye kuri buri cyuma cyicyuma kugirango hamenyekane niba byubahirizwa
• Kuringaniza / kugoreka ibizamini kugirango ugaragaze guhindagurika
• Amashusho, OD, urukuta n'uburebure bugenzura kugirango umenye neza ibipimo
• MTCs kuri EN 10204 3.1 / 3.2 kubushyuhe bwuzuye no kugerageza

Ingingo y'ingenzi ni uko A106 Icyiciro B cyerekanwe mugihe serivisi ari yombinta nkomyinahejuru - ubushyuhe. Iyo ibikenewe ari icyumba - ubushyuhe cyangwa imiterere, abaguzi bakunze kujya kuri ASTM A53 aho; mugihe igikenewe ari umuyoboro wumurongo hamwe nibisabwa na PSL, bajya kuri API 5L. Kugumana iyi page neza neza "hejuru - ubushyuhe bwa CS umuyoboro wa CS" bizafasha Google kumva icyo URL ivuga.

• Umuyoboro wa karuboni idafite icyuma ikorwa kuri ASTM A106 / ASME SA106
• Icyiciro B nkibisanzwe; Icyiciro A cyangwa C mugihe bisabwa numushinga
• Kata - kugeza - uburebure, impera zometseho, gutwikira / varike no gupakira ibicuruzwa hanze
• Ibizamini byose (hydro, NDE, ubukanishi) byanditse kandi birakurikiranwa
• Icya gatatu - ubugenzuzi bwishyaka (BV, SGS, LR, nibindi) birashobora gutegurwa mbere yo koherezwa
• Tanga uburambe kubitunganya, ingufu ninganda za chimique aho impapuro zipapuro zigomba guhura nibisabwa na EPC

Q1: Umuyoboro wa ASTM A106 Icyiciro B ni ikihe?

A1:Ubushyuhe bwo hejuru -, hejuru - imiyoboro yumuvuduko nkumurongo wamazi, imiyoboro itunganya inganda, imirongo yo kugaburira ibyuka, hamwe na serivisi ya peteroli ishyushye.

Q2: Ni irihe tandukaniro riri hagati ya ASTM A106 Icyiciro B na ASTM A53 Icyiciro B?

A2:A106 isobanurwa hejuru ya - serivisi yubushyuhe kandi mubisanzwe ihitamo mugihe hakenewe umuyoboro udafite kashe; A53 ikunze gutoranywa munsi - ubushyuhe / serivisi rusange.

Q3: Ni ibihe bizamini ninyandiko nshobora gusaba kuri ASTM A106 Icyiciro cya B.

A3:Baza ibisubizo bya hydrotest cyangwa NDE, kubahiriza ubukanishi / chimie, ubushyuhe bwuzuye - umubare ukurikirana, hamwe na pake ya EN 10204 3.1 MTC.
