Faamatalaga oloa

O le paipa faʻafefete faʻapipiʻi mo le felauaiga o le suavai maualalo o se paipa uʻamea e faʻaaogaina e felauaiga vai maualalo e pei ole vai, otaota, ea, ma le vevela vevela. O lenei ituaiga o paipa uʻamea e faʻapipiʻiina e ala i le faʻapipiʻiina ma le faʻapipiʻiina otometi arc, lea e iai uiga o le tau maualalo o le gaosiga ma le maualuga o le gaosiga.

O le paipa faʻafefete faʻapipiʻi mo le felauaiga o le suavai maualalo o se paipa uʻamea e faʻaaogaina e felauaiga vai maualalo e pei ole vai, otaota, ea, ma le vevela vevela. O lenei ituaiga o paipa uʻamea e faʻapipiʻiina e ala i le faʻapipiʻiina ma le faʻapipiʻiina otometi arc, lea e iai uiga o le tau maualalo o le gaosiga ma le maualuga o le gaosiga. O nisi nei o fa'amatalaga autu e uiga i paipa uelo fa'asolosolo mo le fa'aliliuina o le suavai maualalo:

Tele ma foliga: O le tele o le faasologa o paipa uelo silo o le a fetuutuunai e tusa ai ma tulaga talafeagai e ausia manaoga eseese talosaga.

Manaoga faʻapitoa: O manaʻoga faʻapitoa mo paipa faʻapipiʻiina e aofia ai metotia gaosiga, ituaiga uʻamea, vailaʻau vailaʻau, mea faʻainisinia, suʻega hydrostatic, suʻega e le faʻaleagaina, foliga lelei, ma isi.

Auala o le gaosiga: E masani ona fa'aogaina fasi uamea e fa'afefeteina e fai ai paipa, e fa'apipi'iina i le vevela o le potu, ma e fa'apipi'i so'oga e fa'asolo i lalo otometi.

Ituaiga uʻamea: Uamea e ogatasi ma tulaga faʻale-atunuu e tatau ona faʻaaogaina, e pei ole Q195, Q215 ma le Q235 uamea ile GB / T 700--1988. O isi ituaiga uʻamea faʻatasi ai ma le lelei o le faʻaogaina o le faʻaogaina e mafai foi ona faʻaaogaina e tusa ai ma le maliliega.

Su'esu'ega e le fa'aleagaina: E tatau ona asiasia e le X-ray po'o le ultrasonic le fa'aleleia o paipa u'amea, u'amea u'amea u'amea ma u'elo fa'ata'amilomilo e fa'amautinoa ai le lelei o le fa'ailoga.

Tulaga lelei: O le pito i luga ole paipa uʻamea e tatau ona lamolemole, ma faʻaletonu e pei o taʻe, maʻila, gaugau, ma isi mea e le faʻatagaina. O faaletonu e le mafai ona iloa le loloto e tatau ona aveese atoatoa e ala i le olo.

Su'ega o le mamafa o le hydrostatic: O paipa u'amea ta'itasi e tatau ona faia i se su'ega o le mamafa o le hydrostatic e fa'amautinoa ai e leai se liki. O le mamafa o le suʻega e faʻatatau ma fuafua e tusa ai ma le fua faʻatatau.

Tulaga Faʻatonu: O le gaosiga ma le asiasiga o paipa faʻafefeteina mo le felauaiga o le suavai maualalo e tatau ona mulimulitaʻi i tulaga faʻale-malo, e pei ole GB / T 3091-2015, ma isi. .

Avanoa o le talosaga: E talafeagai mo paipa felauaiga o le suavai maualalo e pei o vai, otaota, ea, faʻavevela ausa, ma isi, ma e mafai foi ona faʻaoga mo isi paipa felauaiga vai ma manaʻoga tutusa.

Tulaga lelei: Aʻo leʻi tuʻuina atu le paipa faʻapipiʻiina mo le faʻaaogaina, e tatau ona tuʻuina atu se tusi faamaonia lelei e faʻamaonia ai e fetaui ma manaʻoga o tulaga talafeagai.

I se aotelega, o paipa faʻapipiʻi faʻapipiʻiina mo felaʻuaʻiga vai maualalo-ua faʻaaogaina lautele i le fanua o felauaiga o le suavai maualalo ona o lo latou tamaoaiga ma fetuunaiga. E tatau ona mulimulita'ia tulaga fa'ale-atunuu talafeagai i le taimi o le gaosiga ma le fa'aoga ina ia mautinoa le lelei ma le saogalemu o oloa.
