Suauu ta'e paipa tipi faleoloa, suauu ta'e paipa tipi faiga, suauu ta'e paipa e masani lava ona fa'aaogaina e gaosia ai le maualuga o le mamafa ma luga atu o le mamafa o le ausa faumea paipa o le maualuga o le carbon structural u'amea, u'amea faumea u'amea ma le uamea fa'afefe vevela maualuga fa'alava fa'alava, o nei mea. faagaau faufu galue i lalo o le vevela maualuga ma le mamafa, o le paipa i le matafaioi o le maualuga vevela flue kasa ma vai ausa o le a oxidation ma corrosion, o lea e manaomia ai le paipa ta'e suauu e maua ai le malosi tumau maualuga O lea, o le suauu ta'e paipa e manaomia e. maua le malosi maualuga tumau, maualuga oxidation tetee, ma le mautu lelei faalapotopotoga.

O le faʻamaʻaʻaina o le paipa taʻe suauʻu e iai se aafiaga tele i mea faʻainisinia, ae le o vaega faʻainisinia uma e tatau ona faʻamaʻa atoatoa.Mo se faʻataʻitaʻiga, punou, faʻalavelave faʻalavelave faʻamaʻi vaega, vaega o togafitiga vevela, ma isi, e manaʻomia naʻo se loloto o le faʻamaʻaʻaina e fetaui ma manaʻoga o le faʻaaogaina.O le quenchability o paipa ta'e suau'u e tele lava ina fuafuaina e le tau malulu mataʻutia, o le laʻititi o le tau malulu mataʻutia, sili atu le quenchability o paipa taʻe suauu, ma vice versa, o le maualalo o le quenchability o paipa taʻe suauu.I le faʻaopoopoga i le Co, o le tele o elemene faʻafefiloi e mafai ona faʻaleleia atili le malosi o le sila.

Maketi Folasaga

Suauu ta'e paipa maketi i luga ma lalo, o le taaloga umi ma puupuu e malosi, o le maketi ua fefiloi bearish, lea foi na taitai atu ai i le tuputupu ae o le faatalitali-ma-vaai lagona, manaoga maketi na taofia.Talu ai o le aso fefaʻatauaʻiga mulimuli aʻo leʻi oʻo i le aso malolo i le lumanaʻi tau maualalo, ma e leai ni fefaʻatauaʻiga i le lumanaʻi i le taimi o le aso malolo, o le mea lea, o le maketi na tatalaina i le 10th i le lumanaʻi o loʻo i ai pea le faʻaauauina o le paʻu na tupu.Afai e maualalo le lumana'i, i le leai o se tala lelei e fa'ateleina ai le avanoa o le maketi o paipa ta'e suau'u e mulimuli i le pa'u ua si'itia, o le tau o paipa ta'e suau'u e fa'amoemoe e vaivai le tau.
