1. Metallography
Metallography o se tasi lea o auala autu mo le faʻavasegaina o paipa uʻamea maipaipa u'amea lamolemole. O paipa u'amea u'amea maualuga e le fa'aopoopoina mea fa'apipi'i, o lea e vaapiapi tele le su'isu'i i totonu o le paipa uamea. Afai o le auala o le olo talatala ona faʻaaogaina lea o le pala, e le mafai ona vaʻaia lelei le suʻega uelo. O le taimi lava e ueloina ai le paipa uʻamea uʻamea maualuga maualuga ma e leʻi oʻo i togafitiga vevela, o le a matua ese lava le fausaga o le uelo mai le mea matua o le paipa uʻamea. I le taimi nei, e mafai ona faʻaogaina le metotia metallographic e iloagofie ai paipa uʻamea uʻamea mai paipa uʻamea leai. I le faʻagasologa o le faʻavasegaina o paipa uʻamea e lua, e tatau ona tipi se faʻataʻitaʻiga laʻititi ma le umi ma le lautele o le 40mm i le mea faʻapipiʻi, faʻataʻitaʻi talatala, solo lelei ma faʻamalo, ona mataʻituina lea o le fausaga i lalo ole microscope metallographic. Pe a matauina ferrite ma widmanstatten, mea matua ma le fausaga sone uelo, e mafai ona saʻo iloga le paipa uʻamea uʻamea ma seamless uamea.
2. Ala a'a
I le faagasologa o le faʻaogaina o le faʻaogaina o le auala e faʻamaonia ai paipa uʻamea uʻamea ma paipa uʻamea e leai se mea, e tatau ona faʻalelei le faʻaogaina o le faʻaogaina o paipa uʻamea. A maeʻa le faʻalelei, e tatau ona vaʻaia faʻailoga faʻalelei. Ona fa'aiila lea o foliga pito i le sandpaper i le fa'ailoga, ma fa'amama le pito pito i le 5% nitric acid alcohol solution. Afai e aliali mai se faʻailoga manino, e mafai ona faʻamaonia o le paipa uʻamea o se paipa uʻamea. E leai se eseesega manino i foliga pito o le paipa uʻamea seamless pe a uma corrosion.
3. Fa'ailogaina paipa u'amea u'amea ma paipa u'amea seamless e tusa ai ma le faagasologa
I le faagasologa o le faailogainapaipa uamea ueloma paipa uʻamea seamless e tusa ai ma le faagasologa, ua uelo uma paipa uʻamea e tusa ai ma faiga e pei o le taʻavale malulu ma extrusion. E le gata i lea, pe a faʻaaogaina paipa uʻamea maualuga, faʻamaualalo arc ma paipa uʻamea tetee e faʻafefe ai paipa uʻamea, faʻapipiʻiina paipa paipa ma faʻapipiʻi saʻo paipa paipa o le a fausia, lea o le a fausia ai paipa uamea lapotopoto, paipa uʻamea sikuea, uʻamea oval. paipa, paipa u'amea tafatolu, paipa u'amea hexagonal, paipa u'amea solo, paipa u'amea ta'ifa'i, ma e sili atu ona lavelave paipa u'amea. I se faapuupuuga, o faiga eseese o le a fausia ai paipa uʻamea o foliga eseese, ina ia mafai ona iloa manino lelei paipa uʻamea uʻamea ma seamless uamea. Ae ui i lea, i le faagasologa o le faʻavasegaina o paipa uʻamea faʻafefeteina e tusa ai ma le faagasologa, e masani lava ona iloga i latou e tusa ai ma le vevela vevela ma le malulu auala togafitiga, ma o paipa uʻamea faʻafefete e lua foi ituaiga autu, e taʻua o paipa uʻamea vevela vevela ma malulu- taai paipa u'amea lamolemole. O paipa uʻamea faʻafefe vevela e faʻapipiʻiina e ala i le perforation, taʻavale ma isi faʻagasologa, aemaise lava le tele-diameter ma le mafiafia o paipa uʻamea e faʻafefeteina e faʻafefeteina e lenei faiga; o paipa malulu e faia e ala ile ata malulu o paipa, ma o le malosi o le mea e maualalo, ae o ona pito i fafo ma totonu e lamolemole.
