API 5Lmasani e faasino i paipa uamea paipa (paipa paipa) o le faatinoga o le tulaga masani, paipapaipa uameae aofia ai paipa uʻamea seamless ma paipa uʻamea uʻamea lua vaega. I le taimi nei i le paipa suauu e masani ona matou faʻaaogaina paipa uʻamea ituaiga paipa paipa faʻafefete faʻafefe arc uelo paipa (SSAW), su'isu'i sa'o ua fa'afefeteina arc paipa (LSAW), paipa uelo tetee (ERW), paipa u'amea lamolemolee masani ona faʻaaogaina i le laina paipa e itiiti ifo i le 152mm.
O le tulaga faaleatunuu GB / T 9711-2011 uamea paipa mo pipeline faiga felauaiga i le suauu ma alamanuia kasa ua tuufaatasia e tusa ai ma API 5L.
GB / T 9711-2011 o loʻo faʻamaoti mai ai le gaosiga o manaʻoga mo paipa uʻamea faʻafefe ma faʻapipiʻiina e lua tulaga faʻapitoa o oloa (PSL1 ma PSL2) mo auala o felauaiga paipa i totonu o le suauʻu ma le kesi. O le mea lea, o le tulaga masani e faʻaaogaina i paipa uʻamea faʻafefe ma paipa uʻamea uʻamea mo felauaiga o suauu ma kesi, ma e le faʻaaogaina i paipa uʻamea.
Fa'ailoga uamea
O togi uʻamea o mea mataʻutia mo paipa uʻamea o lenei API 5L faʻataʻitaʻiga o GR.B, X42, X46, X52, X56, X60, X70, X80, ma isi. ma le gaosiga e ese foi, ae o le carbon equivalents i le va o togi uʻamea eseese e matua pulea.
Tulaga lelei
I le API 5L pipe standard, o tulaga lelei (poʻo manaʻoga) mo paipa uʻamea e vaevaeina i PSL1 ma PSL2. O le PSL o se fa'apu'upu'u mo tulaga fa'amatalaga o oloa.
O le PSL1 e maua ai se tulaga lautele o mana'oga lelei o paipa; E fa'aopoopo e le PSL2 mana'oga fa'atulafonoina mo le tu'ufa'atasiga o vaila'au, ma'a'a fa'ailoga, mea fa'amalosi, ma NDE fa'aopoopo.
