Malamalama i le Taua o Paipa Kesi Faanatura Lelei: X42 SSAW Paipa, ASTM A139 ma EN10219
X42SSAWpaipao se ituaiga o paipa kasa masani e masani ona faaaoga i le suauu ma alamanuia kesi.O lo'o gaosia i le fa'aogaina o se fa'agasologa o le ueloina o le arc e maua ai paipa maualuga ma tumau.X42 SSAW paipa o loʻo i ai le malosi maualuga ma sili atu vailaʻau faʻainisinia, e fetaui lelei mo manaoga manaʻomia o felauaiga kesi masani.O lona tete'e lelei i le pala ma le ta'e e avea ma filifiliga muamua mo galuega fau paipa.
ASTM A139o le isi tulaga taua mo paipa kesi masani.O lenei fa'amatalaga e aofia ai le electrofusion (arc) fa'apipi'i sa'o po'o le paipa u'amea su'isu'i fa'aoga mo le felauaiga o kasa, ausa, vai ma isi vai.ASTM A139 paipa ua lauiloa mo lona faʻatuatuaina ma le umi o faʻatinoga i lalo o tulaga sili ona faigata.O paipa ia ua mamanuina e tetee atu i le maualuga o le mamafa ma le fesuiaiga o le vevela, ma avea ai ma mea lelei mo le faʻasalalauina o kesi masani ma le tufatufaina atu o talosaga.

EN10219o se tulaga Europa o loʻo faʻamaoti mai ai tulaga faʻapitoa mo le faʻapipiʻiina o vaega faʻapipiʻi malulu faʻapipiʻiina o le uʻamea e le faʻaogaina ma le uʻamea lelei.E ui o le EN10219 e leʻo faʻatulagaina faʻapitoa mo paipa kesi masani, o ona manaʻoga mo le tumau, saʻo saʻo ma mea faʻainisinia ua avea ai ma filifiliga talafeagai mo nisi o galuega faʻapipiʻi kesi.O le fa'aaogaina o paipa e ogatasi ma fa'ata'ita'iga EN10219 e mafai ona fa'aleleia atili ai le fa'amaoni atoa ma le ola tautua o lau faiga fa'asoa kesi masani.
Le taua o le filifilia lelei o paipa kesi masani e le mafai ona soona ta'ua.O paipa le lelei po'o le le lelei o le lelei e mafai ona afaina ai le siosiomaga, saogalemu lautele ma le faʻatuatuaina atoa o sapalai kesi.O le mea lea, e tatau ona fa'amuamua e le fa'aogaina o kesi fa'alenatura, fa'atautaia o paipa ma pule o le poloketi le fa'aogaina o mea fa'amaonia ma fa'amautu lelei e pei ole paipa X42 SSAW, ASTM A139 ma le EN10219.
I se aotelega,paipa kasa masanifilifiliga o se itu taua o le mamanu ma le fausiaina o paipa.O iloiloga lelei, e pei o le malosi o meafaitino, tete'e o le pala, ma le tausisia o tulaga tau alamanuia, e tatau ona una'ia le faiga o filifiliga.E ala i le filifilia o paipa faʻatuatuaina ma taʻutaʻua, e pei o le X42 SSAW pipeline, ASTM A139, ma le EN10219, e mafai e paaga ona faʻamautinoa le ola umi ma le saogalemu o atinaʻe felauaiga kesi masani.
Ma le mea mulimuli, e taua tele le faʻamuamua o le faʻaogaina o paipa kasa sili ona lelei e fetaui ma tulaga faʻapisinisi ma maua ai mea faʻainisinia ma vailaʻau talafeagai.E ala i le filifilia o filifiliga faʻatuatuaina e pei ole X42 SSAW pipeline, ASTM A139 ma le EN10219, e mafai e le au faʻatautaia paipa ona faʻamautinoa le faʻamaoni umi ma le saogalemu o latou faiga faʻasoa kesi masani.
