O paipa uamea kabone e faia i le uamea po'o le u'amea lapotopoto malosi e ala i pu e fai ai capillaries, ona faia lea i le ta'avale vevela, ta'avale malulu po'o le ata malulu.O paipa uamea kabone ei ai se tulaga taua i totonu o le pisinisi faagaau u'amea a Saina.O mea autu e masani lava q235, 20 #, 35 #, 45 #, ma 16mn.O tulaga aupito sili ona taua o le fa'atinoina o oloa e aofia ai tulaga fa'ale-atunu'u, tulaga Amerika, tulaga fa'a Iapani, ma isi, fa'atasi ai ma tulaga fa'ale-atunu'u e aofia ai tulaga fa'ata'ita'iga a le Matagaluega o Alamanuia Fa'atekonolosi, Sinopec paipa fa'apipi'i, ma fa'ainisinia eletise fa'apipi'i tulaga.Se'i o tatou va'ava'ai i aogā o paipa uamea kaponi.

Fa'aaogāina o le fa'alava uamea kaponi:

1. Paipa mo paipa.E pei o: paipa e leai ni mea mo vai, paipa kesi, paipa ausa, paipa suauu, ma paipa mo laina ogalaau suauu ma kesi masani.Fau fau fa'ato'aga ma paipa ma paipa fa'asusu vai, ma isi.
2. Faila mo meafaigaluega vevela.E pei o paipa vai fa'apuna, paipa ausa fa'avevela mo fa'avela lautele, paipa fa'avevela, paipa asu lapopo'a, paipa asu laiti, paipa piliki fa'akomepiuta ma paipa fa'avevela maualuga ma le maualuga o le vevela mo locomotive boilers.
3. Paipa mo alamanuia masini.E pei o paipa fausaga vaalele (paipa lapotopoto, paipa elliptical, paipa elliptical mafolafola), paipa semi-axle taavale, paipa axle, paipa faufale taʻavale taʻavale, paipa faʻamaʻa suauʻu, masini faʻatoʻaga paipa sikuea ma paipa rectangular, transformer paipa ma bearings paipa ma isi. .
4. Paipa mo suau'u suau'u fa'afanua.E pei o: paipa vili suauʻu, paipa vili suauʻu (kelly ma hexagonal vili paipa), paipa vili, paipa suauu, pusa suauu ma sooga paipa eseese, geological vili paipa (paipa autu, casing, paipa vili galue, paipa vili), lolomi paʻu ma sooga pine, ma isi).
5. Paipa mo pisinisi kemisi.E pei o: paipa ta'e suau'u, mea tau vaila'au fa'afesuia'i vevela ma paipa, paipa fa'afefete vai, paipa maualuga-omiga mo fertilizers, ma paipa mo felauaiga ala o vaila'au, ma isi.
6. O isi matagaluega e fa'aaogaina paipa.E pei o: paipa mo koneteina (tubes mo le maualuga-omiga kasa cylinders ma paipa mo koneteina lautele), tubes mo meafaigaluega, paipa mo matamata mataupu, tui tui ma paipa mo masini faafomai, ma isi.

E tusa ai ma mea paipa uamea:

O paipa uamea e mafai ona vaevaeina i paipa carbon, paipa u'amea, paipa uamea, ma isi mea e tusa ai ma mea paipa (ie ituaiga uamea).E mafai ona toe vaevaeina paipa kaponi i paipa uamea masani masani ma paipa fausaga sili ona lelei.E mafai ona toe vaevaeina fa'amau fa'apipi'i i: fa'alava fa'ameamea maualalo, fa'apalapala fa'apipi'i, fa'alava maualuga, ma paipa malosi.Fa'alava fa'alava, fa'a'ave'ave fa'afefete ma le fa'asa'o, fa'alava sa'o (pei o le Kovar), ma fa'alava sili, ma isi.
