O le faʻaogaina o paipa (GB / T8162-2008) o se ituaiga o paipa uʻamea e faʻaaogaina mo le fausaga lautele ma le fausaga faʻainisinia. O le fa'aogaina o paipa u'amea fa'afefete e fa'atatau i paipa u'amea fa'afefe e felauaiga vai.

I le faʻaopoopoga i elemene carbon (C) ma se aofaʻi o le silicon (Si) (e masani lava e le sili atu i le 0.40%) ma le manganese (Mn) (masani e le sili atu i le 0.80%, maualuga atu i le 1.20%) elemene elemene mo le deoxidation, fausaga. paipa uamea , e aunoa ma isi elemene faʻafefiloi (sei vagana ai elemene totoe).

O paipa u'amea fa'apena e tatau ona fa'amaonia uma le tuufaatasiga o vaila'au ma mea fa'ainisinia. O mea o loʻo i totonu o le sulfur (S) ma le phosphorus (P) elemene eleelea e masani ona pulea i lalo ole 0.035%. Afai e pulea i lalo ole 0.030%, e taʻua o le sila maualuga maualuga, ma le "A" e tatau ona faʻaopoopo pe a uma lona togi, pei ole 20A; pe afai o le P e pulea i lalo ole 0.025% ma le S o loʻo i lalo ole 0.020%, e taʻua o le sili atu le maualuga o le paipa uʻamea fausaga, ma o lona togi e tatau ona mulimulitaʻia e Faʻaopoopo "E" e iloagofie ai. Mo isi elemene alloying totoe aumaia i totonu o paipa uamea fausaga mai mea mata, o le anotusi o le chromium (Cr), nickel (Ni), apamemea (Cu), ma isi. e masani ona pulea i Cr≤0.25%, Ni≤0.30%, Cu≤ 0.25%. O nisi vasega o le manganese (Mn) mea e oʻo atu i le 1.40%, e taʻua o le manganese sila.

Le ese'esega i le va o le fa'aogaina o le paipa fa'alelei ma le vai fa'afefeteina paipa:

O le eseesega tele i le va o le paipa uʻamea faʻapipiʻiina o le paipa uʻamea faʻafefeteina o loʻo faʻataʻitaʻiina i suʻega hydraulic taʻitasi poʻo le ultrasonic, eddy current and magnetic flux leakage inspection. O le mea lea, i le filifiliga masani o paipa paipa paipa paipa, e le tatau ona faʻaaogaina paipa uʻamea faʻafefe. O le faʻataʻitaʻiga o le paipa uʻamea le lelei o le pito i fafo, mafiafia puipui, ma le mafiafia o le puipui o le paipa uʻamea e masani ona faʻaaogaina mo masini, maina koale, uamea hydraulic, ma isi faʻamoemoega. O mea o le mafiafia-pa puipui seamless paipa ua vaevaeina i 10 #, 20 #, 35 #, 45 #, 16Mn, 27SiMn, 12Cr1MoV, 10CrMo910, 15CrMo, 35CrMo ma isi.

Structural stainless uamea seamless paipa (GB/T14975-1994) o se vevela-taai (extruded, faalauteleina) ma le malulu toso (taavale) paipa uamea seamless.

Ona o latou faiga eseese gaosiga, ua vaevaeina paipa uʻamea solo i vevela-taavale (extruded) paipa uʻamea seamless ma malulu-tosi (taavale) paipa uʻamea seamless. O fa'a'au'au fa'amalo (ta'avale) ua vaevaeina i ni ituaiga se lua: fa'a'a'ai lapotopoto ma fa'aputu fa'apitoa.

Va'aiga lautele o le faagasologa:
Ta'avale vevela (paipa u'amea fa'a'ese'ese): pili fa'a'au'au lapotopoto → fa'avevela → fa'ava'a → ta'avale skew tolu-loller, ta'avale faifaipea po'o le fa'aulufaleina → aveese fa'apa'u → sizing (po'o le fa'aitiitiga o le lautele) → fa'alili → fa'aulu pili → fa'asa'o → su'ega vai (po'o iloa o mea sese) → faailoga → teuina.

Pipa u'amea fa'afefete (ta'avale) mālūlū: pili fa'a'au'au lapotopoto → fa'avevela → fa'aoso → fa'auluuluga → fa'ama'i → pikiina → su'u (pepa apamemea) → fa'ailoga malulu tele-pass (ta'avale malulu) → pili → vevela → fa'asa'o → Su'ega eletise (fa'aletonu su'esu'ega) → fa'ailoga → fale teu oloa.
