I mea tau alamanuia, o paipa u'amea e taua tele i le fa'amautinoaina lelei o felauaiga o vai ma kasa.O pisinisi eseese e manaʻomia ituaiga faʻapitoa o paipa uʻamea, e faʻatatau i o latou manaʻoga tulaga ese ma tulaga.I aso nei, tatou te vaʻavaʻai totoʻa i le faʻapitoa ma le malosi o loʻo ofoina mai e mea taua paipa paipa e tolu: ASTM A53 Gr.B u'amea paipa uamea, ASTM A192 paipa, ma API 5L Gr.B paipa u'amea lamolemole.
ASTM A53 GR.Bpusa uamea paipa:
ASTM A53 GR.B paipa uʻamea paipa o se vasega o paipa uʻamea fuafuaina mo le maualuga o le vevela ma le maualuga o le faʻaogaina o le mamafa i totonu o pusa ma faʻafefe vevela.O lo'o gaosia e fa'aaoga ai elemene kaponi ma mea fa'afefiloi mo le sili atu le tumau ma le tete'e atu i fa'amamafa fa'ama'i.E le gata i lea, ASTM A53 Gr.O paipa u'amea B o lo'o i ai le maualuga o le carbon content nai lo paipa masani, e maua ai le malosi sili atu ma le faigata.
ASTM A192 Paipa:
O le isi mea e sili ona lelei paipa paipa o le ASTM A192 paipa, e masani ona faʻaaogaina i faiga faʻavevela maualuga ma faʻafefe vevela.ASTM A192 paipa o loʻo fausia mai le maualuga o le carbon steel ma mea faʻainisinia sili ona lelei ma sili ona teteʻe atu i faʻalavelave i totonu ma fafo.
API 5L GR.B paipa u'amea lamolemole:
API 5L GR.B ua fuafuaina mo le felauaiga o kasa masani, suauu ma isi vai.O paipa u'amea fa'alelei o se filifiliga lauiloa i le suau'u ma le kesi alamanuia.O lenei mea paipa uʻamea e sili ona lelei le teteʻe atu i faʻamaʻi faʻainisinia ma faʻamaʻi, faʻapena lelei mo tulaga faigata.
Mai fala i le suauu ma kesi laina felauaiga, ASTM A53 Gr.Bpusa uamea paipa, ASTM A192 paipa ma API 5L Gr.B paipa uʻamea seamless maua faʻaoga tulaga ese i alamanuia eseese.O nei mea faʻapitoa paipa uʻamea o loʻo i ai mea faʻapitoa e pei o le maualuga o le vevela, faʻamaʻi faʻamaʻi ma sili atu le malosi faʻainisinia.
