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 lua vaega. I le taimi nei i le paipa suauu e masani ona matou faʻaaogaina paipa uʻamea paipa ituaiga paipa faʻafefete faʻafefe arc (SSAW), su'isu'i sa'o fa'apa'u fa'asu'e 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; PSL2 fa'aopoopoina mana'oga fa'atulafonoina mo vaila'au fa'apipi'i, ma'a'a fa'ailoga, mea malosi, ma NDE fa'aopoopo.
