Pipeline uamea o se ituaiga uʻamea faʻaaogaina e gaosia ai le suauu ma le kesi pipeline felauaiga faiga. I le avea ai o se meafaigaluega felauaiga mamao mo le suauu ma le kesi masani, o le paipa faiga o loʻo i ai le lelei o le tamaoaiga, saogalemu ma le faʻalavelaveina.
Fa'aoga uamea paipa
Uamea paipafomu oloa e aofia ai paipa uʻamea seamless ma uʻamea paipa uamea, lea e mafai ona vaevaeina i ni vaega se tolu: alpine, nofoaga maualuga-sulfur ma seabed laying.These pipelines ma siosiomaga galue faigata e umi laina ma e le faigofie ona tausia, ma e manaomia tulaga lelei atoatoa. .
O le tele o lu'itau o lo'o feagai ma u'amea paipa e aofia ai: o le tele o suau'u ma kesi o lo'o i totonu o polar regions, aisa, toafa, ma eria o le sami, ma o tulaga masani e fai si faigata;poʻo le faʻaleleia atili o felauaiga, o le lautele o le paipa o loʻo faʻalauteleina pea, ma faʻateleina le mamafa o le tuʻuina atu.
Meatotino uamea paipa
Mai le iloiloga atoa o le atinaʻeina o le suauʻu ma le kesi paipa, pipeline tuʻuina tulaga, autu le manuia auala ma le toilalo mafuaʻaga, pipeline uamea e tatau ona i ai ni mea faʻainisinia lelei (puipui mafiafia, malosi maualuga, malosi maualuga, ofuina teteʻe), ma e tatau foi ona i ai lapoa lapoa, E tatau foi ona i ai le lautele lautele, weldability, malulu ma maualalo vevela tetee, corrosion tetee (CO2), tetee i le sami ma HIC, faatinoga SSCC, ma isi.
①Malosi maualuga
Pipeline uʻamea e le gata e manaʻomia ai le malosi maualuga ma le malosi e maua ai, ae e manaʻomia ai foʻi le fua faʻatatau e maua i le va o le 0.85 ~ 0.93.
② A'afiaga maualuga faigata
e mafai ona fa'amalieina mana'oga o le puipuia o le ta'e.
③Low ductile-brittle suiga vevela
O itulagi faigata ma tulaga tau e mana'omia ai le u'amea paipa ia lava le maualalo o le vevela o le fesuiaiga. o le vaega gau gau o le faʻataʻitaʻiga e ≥85% i le maualalo o le vevela faʻaogaina.
④Toe malosi i le ta'e o le hydrogen (HIC) ma le sulfide stress corrosion ta'e (SSCC)
⑤ Fa'atinoga lelei uelo
lelei weldability o uamea e taua tele ina ia mautinoa le faamaoni ma le lelei uelo o le paipa.
Pipeline Steel Standards
I le taimi nei, o tulaga faʻapitoa faʻapitoa o paipa uʻamea faʻasalalau suauu ma kesi o loʻo faʻaaogaina i loʻu atunuu e aofia aiAPI 5L, DNV-OS-F101, ISO 3183, ma GB/T 9711, ma isi. O le tulaga lautele e faapea:
① API 5L (laina paipa faʻamatalaga) o se faʻasalalauga faʻasalalau lautele faʻatulagaina e le Maine Petroleum Institute.
② DNV-OS-F101 (faiga paipa lalo) o se faʻamatalaga faʻapitoa na faʻatulagaina e Det Norske Veritas mo paipa i lalo o le sami.
③ ISO 3183 o se tulaga faʻatulagaina e le International Organization for Standardization i luga o le tuʻuina atu o tulaga o paipa uʻamea mo le suauʻu ma le kesi.O lenei tulaga e le aofia ai le mamanu ma le faʻapipiʻiina o paipa.
④ O le lomiga lata mai o le GB / T 9711 o le 2017 version. O lenei faʻavae e faʻavae i luga ole ISO 3183: 2012 ma le API Spec 5L 45th Edition.faʻavae i luga o le lua. I le laina ma tulaga e lua o loʻo taʻua, e lua tulaga faʻapitoa o oloa ua faʻamaonia: PSL1 ma le PSL2.PSL1 e maua ai le tulaga maualuga o le paipa laina;E fa'aopoopo e le PSL2 mana'oga fa'atulafonoina e aofia ai vaila'au tu'ufa'atasiga, malosi fa'ailoga, mea malosi ma su'ega fa'aopoopo e le fa'aleagaina (NDT).
API SPEC 5L ma ISO 3183 o faʻasalalauga faʻavaomalo faʻapitoa laina paipa.E ese mai ai, o le tele o kamupani suauʻu i le lalolagi ua masani i le faʻaaogainaAPI SPEC 5L faʻamatalaga e fai ma faʻamatalaga autu mo le faʻatauina o paipa paipa paipa.
Fa'amatalaga oka
O le konekarate oka mo paipa uamea e tatau ona aofia ai faʻamatalaga nei:
① Aofa'i (aofa'i atoa po'o le aofa'i atoa o paipa u'amea);
② Tulaga masani (PSL1 poʻo PSL2);
③Paipa uameaituaiga (seamless popaipa uelo, faiga fa'apipi'i fa'apitoa, ituaiga pito paipa);
④ Faʻavae i luga o tulaga, e pei o le GB / T 9711-2017;
⑤ vasega uamea;
⑥I fafo lautele ma puipui mafiafia;
⑦ Length ma le umi ituaiga (le tipi pe tipi);
⑧ Iloilo le manaʻoga e faʻaaoga le faʻaopoopoga.
