API 5L uamea laina paipa ipu

Fa'amatalaga Puupuu:

Pipeline uamea o se ituaiga o ipu uamea e faaaoga mo pipelines, e masani ona faaaoga i le gaosiga o paipa paipa mo suauu ma kesi faalenatura, faapea foi ma le koale ma fale slurries.O le uamea e le gata e manaʻomia ai le malosi faʻamalosi maualuga, ae e manaʻomia ai foi le maualuga o le vevela o le vevela ma le lelei lelei.

u'amea paipa fa'aonaponei o se u'amea maualalo-carbon po'o le ultra-low-carbon microalloyed sila, o se oloa e maualuga mea fa'atekinisi ma maualuga tau fa'aopoopo.O le tele o mea fou faatekinolosi ausia i le fanua metallurgical i le 20 tausaga talu ai ua faʻaaogaina i le gaosiga o paipa uamea.O le atina'eina o le fa'ainisinia o paipa o le tele o le paipa, o le maualuga o le mamafa o le felauaiga o le kasa, maualuga le malulu, maualuga le fa'aogaina o le siosiomaga, ma le mafiafia o le puipui o le paipa i lalo o le sami.O le mea lea, e tatau ona i ai le malosi maualuga o le paipa faʻaonaponei, maualalo le aʻafiaga o Bauschinger, maualuga le malosi ma le brittleness teteʻe, maualalo le faʻaogaina o le kaponi ma le lelei lelei, ma le tetee i le HIC ma le H2S corrosion.

O le paipa uamea ipu e faʻaaogaina e gaosia ai paipa laina uelo, aua o paipa laina e leai ni mea e faia i le pa lapotopoto, ae le o ni ipu uamea.E masani ona fa'aogaina le ipu mafiafia e maua ai le puipui mafiafia o le su'isu'i sa'o paipa, ma o le u'amea u'amea o lo'o fa'aaogaina e gaosia ai le paipa fa'afefeteina eletise(ERW) ma le paipa fa'afefeteina arc uelo (SSAW).I aso nei, e sili atu ma sili atu tagata faʻatau e manaʻomia le paipa uʻamea uʻamea e gaosia ai paipa laina aua e mafai ona faʻaogaina ipu uʻamea e gaosia ai paipa lapopoa, ma le faʻaopopoga, o le tau o paipa uelo e masani lava ona maualalo ifo nai lo paipa seamless.

Laina paipa ipu uamea mea autu mo le gaosiga o le ERW laina paipa, LSAW laina paipa, SSAW laina paipa, lea e faʻaaogaina i le fausiaina o laina paipa i le suauu, kesi ma le vai felauaiga, e mafai ona faʻaaogaina i le gaosiga o le gaosiga o le gaosiga o le suavai.

E matua'i maualalo le vevela o le arctic, mamafa mamafa i le vasa loloto, fa'asalalauga fa'asao: e o'o lava i tulaga sili ona mata'utia e leai se a'afiaga leaga i a tatou ipu laina.E mafai ona galue pa'u laina paipa i le loloto e oo atu i le 2,800 mita i lalo ifo o le sami.

Matou te ofoina atu fo'i lo'o fa'aofuina fa'alava i fafo o le matafaga fa'apipi'i u'amea fa'apipi'i e tete'e a'e mo le tele o mana'oga i le fa'aogaina o le kasa oona.I le avea ai ma se tagata tomai faapitoa i tekinolosi faʻaonaponei faʻaonaponei faʻaonaponei faʻatasi ma le faʻavaveina o le malulu, o matou o se tasi o taʻitaʻi o pisinisi a le lalolagi.
