Sa'o lelei paipa seamless o se ituaiga o mea uamea paipa maualuga maualuga pe a uma le ata malulu po o le ta'avale vevela. Ona o le lelei o le leai o se oxide layer i luga o le puipui i totonu ma fafo, e leai se leakage i lalo o le mamafa maualuga, maualuga saʻo, maualuga maeʻa, leai se deformation i le punou malulu, flaring, mafolafola ma leai ta'e, sa'o paipa uamea e masani ona faaaogaina mo le gaosiga o pneumatic po'o vaega hydraulic, e pei o fa'agogo po'o fa'agogo suau'u, e mafai ona seamless paipa, ua i ai foi paipa uelo. O le vailaʻau faʻasolosolo o paipa uʻamea saʻo o le carbon C, silicon Si, Manganese Mn, sulfur S, phosphorus P, chromium Cr.

O mea masani mo fa'aau sa'o lelei

O mea masani o le saʻo saʻo faʻalava e leai se mea e 10 #, 20 #, 35 # ma 45 #.

O uiga ma tulaga lelei o le sa'o lelei o le paipa fa'amau:

E tele mea e mafai ona gaosia. Afai lava e le faigata tele le sila, e mafai ona gaosia e tusa ai ma manaʻoga.
Sa'o lelei paipa e masani ona gaosia e ala i le faagasologa ta'avale malulu. O le faiga fa'apitoa e fa'apea:
u'amea lapotopoto → tu'ia → pikiina → ta'avale malulu → ulu ili → pa'u
Faagaau e leai se mea → pikiina → ta'avale malulu → ulu ili → pa'u
O uiga o le sa'o sa'o seamless paipa:
1, maualuga saʻo, faʻasaoina le leiloa o le aofaʻi o tagata faʻaoga i le gaosiga masini.

2, faʻamatalaga, le tele o faʻaoga.

3, oloa mae'a ta'ai malulu ma le sa'o maualuga, lelei tulaga lelei ma sa'o lelei.

4. O le pito i totonu o le paipa uamea e mafai ona faia i foliga hexagonal.

5, o le faatinoga o paipa uamea e sili atu, o le uamea e fai si mafiafia.

Pe a faatusatusa i le uamea malo, e pei o le uamea lapotopoto, faagaau u'amea seamless e tutusa flexural ma torsional malosi ma mama mama. O se ituaiga uʻamea faʻalava o le tamaoaiga, faʻaaogaina lautele i le gaosiga o vaega faʻavae ma vaega faʻainisinia.
Fa'atosina uamea faagaau mautofi le lelei o seamless paipa uʻamea, ae e iai foi ona lava uiga. O le faʻaaogaina o vaega mama gaosiga saʻo e mafai ona faʻaleleia atili ai le faʻaogaina o meafaitino, faʻafaigofie le gaosiga o gaosiga, faʻasaoina mea ma taimi faʻagaioiga, e pei o le taʻavale mama mama, ufiufi jack, ma isi, ua faʻaaogaina lautele i le gaosiga o paipa uamea.
O le faʻalauiloaina ma le faʻaogaina o le faʻaogaina o le faʻaogaina o le paipa e taua tele i le faʻasaoina o le uamea, faʻaleleia le lelei o le gaosiga, faʻaitiitia le faagasologa o le gaosiga poʻo le faʻafaigaluegaina o meafaigaluega, faʻasaoina o tau ma itula faʻagaioiga, faʻaleleia le gaosiga gafatia ma le faʻaaogaina o meafaitino, ma le faʻaleleia o le lelei o oloa, faʻaitiitia tau, ma faaleleia o faamanuiaga tau tamaoaiga. E masani lava, o le alamanuia e maualuga le saʻo manaʻoga e faʻaogaina le saʻo lelei o le faʻaogaina o le paipa, e leai se saʻo manaʻomia o le tele o le faʻaogaina o le paipa, pe a uma, o le tau o faʻamatalaga tutusa o le saʻo le faʻaogaina o le paipa e maualuga atu nai lo le faʻaogaina o le paipa.
