PE Vaipaipa ma Feso'ota'iga Tekonolosi

Fa'atasi ai ma le fa'avavevaveina o le fa'anofofale ma le fa'aleleia atili o le fa'alauiloaina o le puipuiga o le si'osi'omaga, PE (polyethylene) paipa vai ua faasolosolo ona suia uamea masani ma paipa PVC e avea ma mea e sili ona fiafia i ai mo le suavai, kesi, fa'ato'aga fa'ato'aga ma isi fa'ato'aga ona o le mama, uiga fa'a'ele'ele ma fa'alelei le si'osi'omaga. Peitai, PE paipa lelei faatinoga e mafai ona iloa atoatoa, o le ki o lo'o taoto i le sa'o feso'ota'iga tekonolosi.

1, PE paipa vai: meafaitino ma mea aoga autu

1.1 O le a le paipa vai PE?  

PE (Polyethylene) o se resini thermoplastic, e tusa ai ma le density ua vaevaeina i le HDPE (polyethylene maualuga maualuga) ma le LDPE (polyethylene maualalo maualalo). O le HDPE e faʻaaogaina lautele i paipa faʻamalosi ona o lona malosi maualuga, maualalo le vevela tetee (-60 °C i 60 °C) uiga; LDPE mo fa'aaliga maualalo maualalo, e pei o faiga fa'asusu.

1.2 Lima lelei o paipa vai PE

Malosi le pala: fa'ato'a fa'ate'aina uma fa'afitauli ele ma pala o paipa u'amea, ma se olaga tautua e oo atu i 50 tausaga.  

Fesuia'i ma etetee i a'afiaga: e mafai ona punou ma fa'ata'atia e fa'afetaui i laufanua lavelave, lelei le faatinoga o le seismic.  

Soifua Maloloina ma le puipuiga o le siosiomaga: e le oona, leai se manogi, e tusa ai ma tulaga faatonuina o le suavai taumafa, fa'agasologa o gaosiga maualalo-carbon.  

Mama ma faigofie ona faʻapipiʻi: ua na o le mamafa 1/8 o paipa uamea, felauaiga ma fau fale ua matua faaleleia.  

Maualalo tafe tetee ma le malosi faasaoina: puipui i totonu lamolemole, e le faigofie ona fua mo le faʻaaogaina umi, faʻaitiitia le faʻaaogaina o le malosi o le pamu.

2, PE paipa feso'ota'iga tekonolosi: 3 auala masani

2.1 Metotia feso'ota'iga fa'afefete (sili ona fa'aaogaina)  

Mataupu Faavae: e ala i le faʻamafanafanaina o le pito paipa PE faʻafefe foliga, fusi fa'amalosi i le tasi, faia o se faamaufaailoga tumau.  

Vaaiga talafeagai: diameter ≥ 63mm paipa, aemaise lava mo galuega tanu tuusao i lalo o le eleele.  

Laasaga o galuega:  

1. Fa'atonuga tipi: fa'aaoga le tipi paipa fa'apitoa e fa'amautinoa ai e mafolafola ma sa'oloto le koluse.  

2. ipu fa'avevela fa'ameamea: seti le vevela i 210 ± 10 ℃, o le taimi faʻamafanafana e faʻafetaui e tusa ai ma le lautele o le paipa (e pei ole DN110 paipa ave e uiga i 45 sekone).  

3. fusion pressurization: vave aveese le ipu faamafanafana, fa'aaoga le mamafa 0.15MPa e fa'atasi ai pito e lua o le apa u'amea.  

4. Fa'alili ma fa'alelei: taofi le mamafa ma malulu i lalo ifo o le 40 ℃ e aloese ai mai le faʻaleagaina o le atinaʻe.  

Fa'aeteete:  

Fa'atele le taimi fa'avevela pe a o'o ifo i lalo ifo le 5 ℃ le vevela.  

Fa'asa le vai po'o le ie susu e faatelevave ai le mālūlū ina ia puipuia ai ma'eta'e.  

2.2 Electrofusion auala feso'ota'iga (sa'o ma lelei)  

Mataupu Faavae: Fa'aoga paipa fa'apipi'i ma uaea fa'amautu e fa'aoso ai le vevela, liusuavai le paipa PE ma le puipui i totonu o le paipa faʻapipiʻi e iloa ai le fesoʻotaʻiga lemu.  

Vaaiga talafeagai: vaapiapi faagaioiga po o le toe faaleleia, talafeagai mo DN20-DN315 paipa diameter.  

Fa'agasologa o galuega:  

1. togafitiga luga: solo ese le vaega fa'ama'i i le pito o le paipa ma fa'ailoga le loloto fa'aofi.  

2. Fonotaga o paipa: Fa'aofi le paipa i totonu o le lima eletise i le laina maka. 3.  

3. Fusi malosi: seti le voltage ma le taimi e tusa ai ma le tulafono o paipa paipa (masani 220V, 3-30 minute).  

4. Fa'alili faanatura: Aua nei fa'agaoioi le paipa i le taimi o le malulu.  

Fa'amanuiaga:  

Tulaga maualuga o masini, faaitiitia le sese o tagata.  

Faʻapitoa mo le fesoʻotaʻiga fesoʻotaʻiga o paipa o mea eseese.  

2.3 Metotia feso'ota'iga (fetuutuunai ma vave)  

Mataupu Faavae: O le fa'amaufa'ailogaina fa'aletino e fa'ataunu'uina e ala i laugutu, pipii ma isi vaega uamea e aunoa ma le faamafanafanaina.  

Tala fa'atatau: galuega lē tumau, laina paipa e le o faʻamalosi poʻo vaega e masani ona talepeina.  

Ituaiga masani:  

Feso'ota'iga flange: O le ulu lau'au o le PE ma le au'au u'amea fa'amau, mana'omia le fa'aopopoga fa'amau fa'amau.  

So'oga pipii: Mea fa'amau fa'amau fa'amau fa'amau fa'atasi ma pa, talafeagai mo paipa laiti lapoa.  

Itu lelei ma le le lelei:  

Tulaga lelei: saoasaoa fau, e mafai ona talepe ma toe fa'aoga.  

Fa'aletonu: omiga umi e mafai ona tafe, mana'omia le tausiga faifaipea.  

3, le ki i le lelei o feso'ota'iga

3.1 Fa'afeso'ota'i liki

Mafuaaga: le lava le taimi fa'avevela po'o le mamafa o le mamafa.  

Fa'asagaga: Fa'aaogā le vevela infrared e mata'itu ai le vevela o le fusu'aga ma fa'amautinoa le mamafa faifaipea.  

3.2 Pipa Eccentricity

Mafuaaga: O le tipiina o paipa e le sa'o po'o le fa'apipi'i e le fa'aoga.  

Puipuiga: Fa'aaogā masini vili itu e lua e fa'afetaui ai le pito pito, ma faʻaaoga le laser positioner e faʻavasega i le taimi o faʻapipiʻi.  

3.3 Fa'ailoga uelo sese

Fa'aaliga: Pulu po'o fa'ailoga o le le fa'afefiloi i totonu o le vaega fa'afefiloi.  

Togafitiga: Oti ese ma toe solder vave, siaki le mama ma le mautu o le vevela o le ipu faʻamafanafana.  

3.4 Luitau Fausia o le Taumalulu

Lu'i: O le maualalo o le vevela e mafua ai le faaumiumi o le liusuavai ma vave tele le malulu.  

Fofo: Fausia se fale e teu ai le vevela, mua'i fa'avevela le paipa i luga a'e o le 10 ℃ ma fa'aoga mea fa'aogaina eletise eletise maualalo.  

4. Fa'afefea ona filifili paipa PE ma auala feso'ota'iga?  

4.1 Taiala filifili paipa

Tulaga mamafa: SDR11 (1.6MPa) e talafeagai mo le suavai a le malo, SDR17 (0.6MPa) e fa'aaogaina mo le fa'asusu vai.  

Tulaga fa'amaonia: iloa GB/T 13663 tulaga fa'alenu'u po'o le ISO 4427 tusipasi faavaomalo.  

Eseese lanu: lanu uliuli (UV tetee, fa'aoga i fafo), lanu moaga (vai inu), yellow (kesi).  

4.2 Decision tree of connection methods

Long-term buried works → hot melt connection

Space constraints or emergency repairs → electrofusion connection

Temporary/demountable demand → mechanical connection

5. Tausiga: the secret to extend the life of PE pipes

1. Regular inspection: check the UV aging of the exposed parts and wrap the protective layer if necessary.  

2. Cleaning tips: use 0.3MPa low-pressure water flushing to avoid high-pressure water gun damage to the inner wall.  

3. Frost crack prevention: add tracer tape in cold areas, or use deep burial (30cm below the permafrost layer).  

PE water pipe and scientific connection technology, marking the pipeline engineering into a new era of high efficiency and environmental protection. Whether it is a family water supply renovation, or large municipal projects, mastering the correct selection and construction methods will maximize the advantages of PE materials. With the popularization of intelligent temperature control equipment and automated welding robots, PE pipe connection is developing in the direction of greater precision and reliability.
