Paipa lainaO le felauaiga lea o le suāuu, kesi po'o le vai ua maua mai le eleele i pisinisi gaosi suāuu ma kesi e ala i paipa laina. O paipa laina e aofia ai paipa e leai ni so'oga ma paipa ua fa'apipi'i. O pito o paipa e lamolemole, pito e filo ma pito o soketi; o auala e fa'apipi'i ai o le fa'apipi'iina o pito, fa'apipi'i soketi, fa'apipi'i soketi, ma isi.

API SPEC 5L-2018(Fa'amatalaga o laina paipa) ua tu'ufa'atasia ma lolomiina e le American Petroleum Institute ma e masani ona fa'aaogaina i le lalolagi atoa.

E tusa ai ma manaʻoga eseese o le faatinoga oGB/T9711-2017paipa uʻamea, e mafai ona vaevaeina le faʻamaʻaʻaina i ituaiga nei e tusa ai ma le vevela o le faʻamaʻaʻaina:
1. Fa'amalūlūina i le vevela maualalo (150-250 tikeri)
O le fausaga e maua mai i le fa'ama'a'aina i le vevela maualalo o le martensite fa'ama'a'aina. O lona fa'amoemoe o le fa'aitiitia lea o le fa'alavelave i totonu ma le ma'ale'ale o le u'amea ua fa'ama'a'aina a'o fa'atumauina pea le malosi maualuga ma le tete'e maualuga i le ofuina o le u'amea ua fa'ama'a'aina, ina ia 'alofia ai le māvaevae pe fa'aleagaina vave i le taimi e fa'aaogaina ai. E fa'aaogaina tele mo le tele o meafaigaluega tipi e tele le kaponi, meafaigaluega fuaina, paipa u'amea GB/T9711, u'amea ta'avale ma vaega ua fa'apipi'iina i le kasa, ma isi mea fa'apena. O le malosi pe a uma ona fa'ama'a'aina e masani lava o le HRC58-64.
2. Fa'amalūlūina i le vevela feololo (250-500 tikeri)
O le fausaga e maua mai i le fa'ama'a'aina i le vevela feololo o le troostite fa'ama'a'aina. O lona fa'amoemoe ia maua le malosi maualuga, tapula'a fa'alelei ma le malosi tele. O le mea lea, e fa'aaogaina tele mo le togafitia o paipa u'amea eseese GB/T9711 ma mamanu fa'avevela, ma o le malosi pe a uma ona fa'ama'a'aina e masani lava o le HRC35-50.
3. Fa'amālūlūina i le vevela maualuga (500-650 tikeri)
O le fausaga e maua mai i le fa'ama'a'aina i le vevela maualuga o le troostite fa'ama'a'aina. O le togafitiga fa'avevela e tu'ufa'atasia ai le fa'ama'a'aina ma le fa'ama'a'aina i le vevela maualuga e masani ona ta'ua o le fa'ama'a'aina ma le togafitiga fa'ama'a'aina, o lona fa'amoemoega o le mauaina lea o meatotino fa'amasini atoatoa ma le malosi lelei, ma'a'a, palasitika ma le ma'a'a. O le mea lea, e fa'aaogaina lautele i vaega taua o le fausaga o ta'avale, paipa u'amea GB/T9711, meafaigaluega masini, ma isi mea, e pei o u'amea feso'ota'i, polo, kia ma au. O le ma'a'a pe a uma ona fa'ama'a'aina e masani lava HB200-330.
