Paipa u'amea pipii mo felauaiga kesi

Faamatalaga oloa

O le paipa u'amea lapo'a lapoa o lo'o fa'aaogaina e felauai ai kesi fa'alenatura o se ituaiga o paipa ua fa'atulaga faapitoa e felauaiga kasa fa'alenatura i mamao mamao. E i ai le tele o mea lelei e avea ai ma filifiliga lelei mo felauaiga malosi. O lo'o mulimuli mai o se fa'atomuaga i nisi o uiga autu ma fa'aoga o paipa u'amea li'o lapoa

O le paipa u'amea lapo'a lapoa o lo'o fa'aaogaina e felauai ai kesi fa'alenatura o se ituaiga o paipa ua fa'atulaga faapitoa e felauaiga kasa fa'alenatura i mamao mamao. E i ai le tele o mea lelei e avea ai ma filifiliga lelei mo felauaiga malosi. O lo'o taua i lalo o se fa'atomuaga i nisi o uiga autu ma le fa'aogaina o paipa u'amea li'o tetele:

Malosi maualuga ma le tumau: O paipa uʻamea uʻamea o loʻo gaosia i mea uʻamea maualuga, e pei ole X70 ma X80 sila. O nei mea e maua ai le malosi maualuga ma le tumau ma e mafai ona tatalia le faʻalavelave i lalo o tulaga faʻasalalau maualuga.

Tamaoaiga: Pe a faatusatusa i isi ituaiga o paipa uʻamea, o paipa uʻamea siʻosiʻomaga e sili atu le tamaoaiga i le gaosiga o le gaosiga ona e mafai ona gaosia e faʻaaoga ai coils poʻo fasi uʻamea eseese lautele, ma faʻaitiitia ai otaota meafaitino.

Lelei le fa'atinoina o le u'amea: O paipa u'amea ta'amilomilo e gaosia e ala ile fa'atekonolosi u'u arc li'o. O lenei auala faʻapipiʻi e maua ai le lelei o le faʻaogaina ma le faʻamaufaʻailogaina, faʻamautinoa le faʻamaoni ma le saogalemu o le paipa.

Fuafuaga lapoa tetele: O le mamanu lapoa tele e sili atu ai le lelei o le paipa uʻamea siʻo pe a felauaiga le tele o kasa masani, faʻaitiitia le gau o le mamafa ma faʻaleleia le lelei o le felauaiga.

Anti-corrosion togafitiga: Ina ia faʻalauteleina le ola tautua ma puipuia le pala, o paipa uʻamea faʻasolosolo e masani ona faʻapipiʻiina i mea faʻapipiʻi faʻamaʻi, e pei o le fused epoxy powder coating fafo, coal tar enamel i fafo anti-corrosion layer, ma isi.

Tulaga Fa'ava-o-malo: O le gaosiga o paipa u'amea e mulimulita'i i se faasologa o tulaga fa'ava-o-malo, e pei ole ISO 3183:2019, fa'amautinoaina le lelei ma le fa'atinoga.

Fa'atekonolosi fa'afouga: I nisi o galuega fa'apipi'i tetele, e pei o le Central Asia Natural Gas Pipeline Project, o le tele o fa'atekonolosi fa'afouga ua fa'aaogaina, e aofia ai le fa'aogaina o le fa'aogaina o le fa'aogaina o mita eletise, ma le RTTM laina leakage auala e iloa ai.

Fetuunaiga o le siosiomaga: E mafai ona faʻaogaina paipa uʻamea faʻasolosolo i tulaga eseese o le siosiomaga, e aofia ai le sopoia o laufanua lavelave e pei o vaitafe ma le Gobi Desert, aʻo gauai atu i le puipuiga o le siosiomaga ma le puipuiga o le siʻosiʻomaga.

Fa'amanuiaga tau tamaoaiga: E ala i fa'atekonolosi fa'afouga ma fa'ata'ita'iga fa'ata'ita'iga, o le fa'aogaina o paipa u'amea e mafai ona fa'asaoina lelei le fa'afaigaluegaina o le poloketi ma tau fa'agaioiga ma fa'aleleia ai fa'amanuiaga tau tamaoaiga.

Fa'amanuiaga fa'aagafesootai: O le fa'aogaina o paipa u'amea i le felauaiga o kesi fa'alenatura e fesoasoani e fa'aleleia atili le fa'aogaina o le malosi, fa'aitiitia le kasa oona, ma e iai sona sao taua i le puipuiga o le si'osi'omaga ma le fa'aleleia o le soifuaga o tagata.

ua avea paipa u'amea li'o tetele-diameter o se filifiliga lelei mo le felauaiga kasa faalenatura ona o lo latou malosi maualuga, tamaoaiga, lelei faatinoga uelo ma adaptability siosiomaga, ma ua faia se matafaioi autu i le tele o galuega faatino pipeline tetele i le fale ma fafo.
