O le paipa u'amea le lelei e faia i le u'amea u'amea po'o le fa'amama mautu avanoa avanoa i totonu o le fulufulu mamoe, ona faia lea i le ta'avale vevela, ta'avale malulu po'o le ata malulu. Seamless paipa uʻamea o loʻo i ai se vaega gaogao, o se numera tele o le faʻaaogaina mo le faʻaaogaina o paipa vai, paipa uʻamea ma uʻamea lapotopoto ma isi uamea malo, i le punou ma le torsional malosi i le taimi lava e tasi, mama mama, o se ituaiga o vaega tau tamaoaiga o le uamea, faʻaaogaina lautele i le gaosiga o vaega faʻavae ma vaega faʻainisinia, e pei o le suauʻu viliina uʻamea scaffolding.
2. Tala'aga o le atina'eina o paipa uamea
O le gaosiga o paipa u'amea seamless o lo'o i ai se tala'aga o le toeitiiti 100 tausaga. O le au Siamani Manisman na muamua fatuina le lua-maualuga skew tu'ia masini i le 1885, ma le mea fou o le paipa ta'avale masini taimi i le 1891. I le 1903, le Swiss RCStiefel na fatuina le masini ta'avale paipa otometi (fa'a ta'ua o le pito i luga paipa ta'avale masini) , ma mulimuli ane faʻaalia le faʻaauau pea o paipa taʻavale masini ma paipa tuleia masini ma isi masini faʻalautele, amata ona fausia le faʻaonaponei seamless paipa paipa alamanuia. I le vaitau o le 1930, na faʻaleleia atili ai le tulaga lelei o paipa uʻamea e ala i le faʻaaogaina o masini taʻavale paipa e tolu-maualuga, masini faʻapipiʻi ma masini taʻavale paipa malulu. I le vaitau o le 1960, ona o le faʻaleleia atili o le paipa faʻasolosolo masini, o le tulaʻi mai o le tolu-roll perforator, aemaise lava le faʻaogaina o le faʻaitiitia o le faʻalavelave ma le faʻaauauina o le faʻaogaina o le paʻu manuia, faʻaleleia le lelei o le gaosiga, faʻaleleia le paipa faʻafefe ma paipa paipa tauvaga gafatia. I le 70's seamless paipa ma uelo paipa o loʻo faʻataʻitaʻi, o le gaosiga o paipa uʻamea o le lalolagi i se fua faatatau e sili atu i le 5% i le tausaga. Talu mai le 1953, ua faʻapipiʻiina e Saina le taua tele i le atinaʻeina o paipa uʻamea le lelei, ma na muamua fausia se faiga gaosiga mo le taʻavaleina o paipa tetele, feololo ma laiti. O le paipa apamemea e masani ona faʻaogaina koluse ingot - taʻavale perforation, vili vili taʻavale, faʻasologa o ata tusi.
3. Fa'aoga ma le fa'avasegaina o paipa u'amea fa'alelei
Fa'aaogā:
paipa uʻamea seamless o se ituaiga o le tamaoaiga cross-vaega uamea, ei ai se tulaga taua tele i le tamaoaiga o le atunuu, faʻaaoga lautele i le suauu, alamanuia vailaʻau, fata, nofoaga eletise, vaa, gaosiga o masini, taavale, vaalele, aerospace, malosi, geology , fausiaina ma le militeli ma isi vaega.
Fa'avasegaga:
(1) E tusa ai ma foliga o le vaega, ua vaevaeina i paipa vaega lapotopoto ma vaega faʻapitoa-foliga paipa
(2) E tusa ai ma mea: paipa uʻamea carbon, paipa uʻamea uʻamea, paipa uʻamea uʻamea, paipa tuʻufaʻatasia
(3) E tusa ai ma le faiga fesoʻotaʻiga: paipa fesoʻotaʻiga filo, paipa uelo
(4) E tusa ai ma le auala gaosiga: taʻavale vevela (extrusion, pito i luga, faʻalauteleina) paipa, taʻavale malulu (tusi) paipa
(5) e ala i le faʻaaogaina: paipa paipa, paipa suauʻu paipa, paipa paipa, fausaga paipa, vailaʻau faʻamaʻi paipa ......
4, seamless paipa paipa faagasologa gaosiga
① Fa'agasologa o le gaosiga (fa'asologa o asiasiga autu) o paipa u'amea fa'afefete fa'afefeteina:
Sauniuniga ma le asiasiga o le paipa avanoa → faʻamafanafanaina o le paipa faʻapipiʻi → faʻamaʻi → Taʻavale o le faʻauʻu → toe faʻamafanafanaina o le paipa i otaota → faʻapipiʻi (faʻaitiitia) le lautele → vevela vevela → faʻasaʻo o paipa maeʻa → faʻamaeʻaina → asiasiga (e le faʻaleagaina, faaletino ma vailaʻau, asiasiga laulau) → teuina
② Ma'alili ta'avale (tusi) paipa u'amea seamless faiga autu gaosiga
Sauniuniga gaogao → u'u pikiina → ta'avale malulu (tusi) → togafiti vevela → fa'asa'o → fa'auma → asiasiga.
5. O le faagasologa o le gaosiga o siata tafe o paipa u'amea su'esu'e vevela e faapea:
