API 5L e masani lava ona faasino i le faʻatinoina tulaga mo paipa uʻamea paipa, lea e aofia ai vaega autu e lua:paipa u'amea lamolemolemapaipa uamea uelo. I le taimi nei, o le masani faʻaaogaina ituaiga paipa uʻamea i paipa suauu opaipa fa'afefeteina fa'asu'e i lalo(SSAW PIPE),paipa fa'apa'u fa'apa'u fa'apa'u(LSAW PIPE), mapaipa uelo tetee eletise(RW). E masani lava ona filifilia paipa u'amea e leai se mea pe a itiiti ifo i le 152mm le lautele o le paipa.
O le tulaga faaleatunuu GB / T 9711-2011, uamea paipa mo Pipeline Femalagaiga Systems i Petroleum ma Natural Gas Alamanuia, na atiina ae e faavae ile API 5L.
GB / T 9711-2011 o loʻo faʻamaoti mai ai manaʻoga mo le faʻaogaina o paipa uʻamea ma uʻamea o loʻo faʻaaogaina i le suauʻu ma kesi faʻalenatura auala felauaiga, e aofia ai tulaga faʻapitoa e lua (PSL1 ma PSL2). O le mea lea, o lenei tulaga e faʻaaogaina naʻo paipa uʻamea e leai se mea ma faʻafefe mo le suauʻu ma le kesi ma e le faʻaaogaina i paipa uʻamea.
Fa'ailoga uamea
API 5L paipa uʻamea faʻaaogaina togi mea mata eseese e aofia ai GR.B, X42, X46, X52, X56, X60, X70, X80, ma isi. Ua fausia nei uamea paipa ma togi X100 ma le X120. O togi u'amea 'ese'ese e tu'uina atu mana'oga ma'oti i mea mata'utia ma fa'agasologa o gaosiga.
Tulaga Tulaga
I totonu ole tulaga API 5L, o le lelei o le u'amea paipa ua fa'avasegaina ile PSL1 po'o le PSL2. O le PSL o loʻo tu mo le Laʻasaga Faʻamatalaga o Mea.
PSL1 o loʻo faʻamaoti mai ai manaʻoga masani mo le uʻamea paipa; E fa'aopoopo e le PSL2 mana'oga fa'atulafonoina mo le tu'ufa'atasiga o vaila'au, malosi fa'ailoga, mea malosi, ma su'ega NDE fa'aopoopo.
