Pipeline pipe: ko te hinu, hau, wai ranei i tangohia mai i te whenua ka haria ki te umanga hinu me te hau ma te paipa paipa.Ko te paipa paipa e rua nga momo paipa tuitui me te paiherea, ko te pito paipa he pito papatahi, he pito miro me te pito turanga;Ko te aratau hononga ko te mutunga o te hononga, te hononga kara, te hononga turanga me etahi atu.
Pipeline pipe: te hinu, te hau, te wai ranei i tangohia mai i te whenua ka haria ki te ahumahi hinu me te hau ma te pipeline pipeline.Welded pipe e honoa ana e te putorino raina honohono, i te nuinga o te waa he roa ake te roa, ka makona i te papatipu o te kaiwhakamahi, engari he pumau. kaore i te pai ki te papatipu whakakotahi o te ngongo korekore, engari he poto ake te roa o te ngongo tuitui, kaore e taea e te kaihoko te whakamahi i te tawhiti roa, kei te whakamahi nga kaihoko me mahi. collocation use both.The pipeline comprises two kinds of seamless and weld pipe, te pito paipa he pito papatahi, he pito miro me te pito turanga;Ko te aratau hononga ko te mutunga fehokotaki, hononga kara, hononga turanga me era atu.
Ki te whanaketanga o te paipa paipa hangarau pereti maitai me te ahunga whakamua o paipa paipa hanga, hangarau fehokotaki'anga, te awhe tono o te putorino ki putorino paiherea i roto i āta whakawhänui, rawa i roto i te whanui nui paiherea putorino piha piha piha te painga o atu mākū, me te utu. Ko nga take, ko te putorino paiherea te tino rangatira i roto i te putorino raina, e whakawhāiti ana i te whakawhanaketanga o te putorino raina maitai korekore.
API5L pipeline putorino production Kei te whakamahi i tēnei wā microalloying tukanga maimoatanga whakawera, he kowiri tira paipa tuitui utu production paipa he tino teitei ake i te putorino paiherea, me te ki te whakapai ake o te kōeke maitai, pērā i X80 maitai kōeke putorino i runga i te rohe o te waro ōrite, te tukanga tikanga o te paipa maitai tui he uaua ki te whakatutuki i nga whakaritenga a te kaiwhakamahi
Ka wehea te putorino maitai tuku ki PSL1, PSL2 e rua nga tohu hua, ko te rereketanga nui ko te PSL2 ka whakaritea ki te PSL1 i runga i te waro rite, te uaua pakaru, te kaha o te kaha me te kaha o te kaha o te kaha. stricter.Ko nga whakamatautau kore kino o nga ngongo kore he whakahau. Ko nga mea kei roto i te raihana me te whaiwhai i muri i te whakamatautau he whakahau.
Ko nga whakaritenga matua mo nga paipa hinu me te hau mo te rino ko:
1. Te kaha: Ko te paipa hinu hinu me te hau e hangaia ana i runga i te kaha o te kaha o te maitai.Ka taea e nga paipa me te kaha o te kaha te kaha ake te kaha o te kaha o te mahi.
2. Toughness: Higher toughness of steel pipe can bring a lower rate of oil and gas pipeline rupture aituā, na API 5L stipulates e, i tua atu ki ngā āhuatanga pūkaha tikanga, v-notch Charpy whakamātautau pānga me te maturuturunga iho hama hammer whakamātautau kia tāpirihia, me te putorino maitai kia tino whakamatautau kore kino i mua i te wehe atu i te wheketere.
3. Weldability: Na te ahua kino o te mara mo te whakatakoto i nga pipelines, ka hiahiatia te pai o te weldability i roto i te reke fehokotaki'anga o paipa maitai.Pipes ki te weldability iti ka whai kapiti i te tui fehokotaki'anga i roto i te fehokotaki'anga, e ka whakapiki ake i te pakeke me te uaua o te tui fehokotaki'anga. me te waahi e pa ana ki te wera, me te whakanui ake i te pakaru o te pipeline. pakeke.E ai ki te awe o nga huānga whakakotahi i runga i te waahi whakawhiti martensite me te wheako mahi, ka taea te whakamahi i te tauira tatau o te waro rite ki te arotake i te pai o te maitai. Ko te tikanga, ko te nuinga o nga mira rino kei raro iho i te 0.35%.
4. Maamaa: Ki te he iti te ductility, ka arahi i te reira ki te hanganga o te rino paraharaha wāwāhi i roto i te matao piko whati cambium ranei i roto i fehokotaki'anga.No reira, API paerewa mo paipa paipa i roto i o te whakamātautau flattening whakaritea, engari me hoki te kiritaki-arahi. whakamātautau piko makariri.Ko te matua ki te whakapai ake i te ductility ko te whakaiti i nga whakauru kore-whakarewa i roto i te maitai me te whakahaere i te morphology me te tohatoha o nga whakauru.
5. Te parenga waikura: i te wa e kawe ana i te hinu whanariki me te hau, te hauwai sulfide me te waro hauhaa i roto i te wai ka arahi ki te hauwai me te ahotea te pakaru o nga ngongo maitai. Ko nga mea penei i te whakahaere i te ihirangi whanariki, te whakahaere i te puka sulfide me te whakapai ake i te uaua ki te matotoru o te pakitara. Ko ona ahuatanga matua ko te microalloying me te whakahaere o te hurihuri, ka taea te whiwhi i te kaha nui, te uaua teitei, te kirihou teitei me te pai. weldability under hot rolling condition.In kia tino tutuki nga whakaritenga mahi o te hinu me te hau pipelines mo te rino, hoahoa koranu tino, whanariki, ūkuikui me etahi atu mea kino he tino mana whakahaere. te kirihou me te pakari o te maitai, ina koa ko te uaua whakawhiti.
Taupānga
Ka whakamahia te pipeline ki te kawe i te hinu, te mamaoa me te wai i toia mai i te whenua ki nga umanga umanga hinu me te hau ma te paipa.

Whakaritenga Whakamatau
Te whakamatautau hydrostatic
Ko te paipa kia mau ki te whakamatautau hydrostatic me te kore e pakaru mai i te tui whiri, i te tinana paipa ranei. Kaore e tika kia whakamatauria nga hononga ki te hydrostatic mena kua pai te whakamatau i nga waahanga paipa i whakamahia.
Whakamatautau piko
Karekau he kapiti ki roto i tetahi waahanga o te waahanga whakamatautau, kaore hoki e puta te whakatuwheratanga o te paihere.
Whakamātautau papatahi
Ko nga paearu whakaae mo te whakamatautau papatahi ko:
- Paipa EW D<12.750 in:
- X60 me T 500in. Karekau he tuwhera o te weld i mua i te iti iho o te tawhiti i waenga i nga papa i te 66% o te diameter o waho. Mo nga reanga me nga pakitara katoa, 50%.
- Mo te paipa me te D/t> 10, kaua e whakatuwherahia te weld i mua i te iti iho o te tawhiti i waenga i nga papa i te 30% o te diameter o waho.
- Mo etahi atu rahi tirohia te katoa o nga korero API 5L.
Ko te whakamatautau a te CVN mo te PSL2
He maha nga rahi paipa PSL2 me nga tohu e hiahia ana kia CVN. Ko te paipa tuitui ka whakamatauria ki te tinana. Ko te paipa paihere me whakamatauria i roto i te tinana, te paipa paipa me te rohe e pa ana ki te wera. Tirohia te katoa o nga korero API 5L mo te tūtohi o nga rahi me nga tohu me nga uara hiko whakauru.
