O le paipa u'amea palasitika laina i le u'amea seamless paipa uʻamea ma uelo paipa ua faʻaaogaina e fai ma paipa faavae.O le puipui i totonu o loʻo faʻapipiʻiina i le meaʻai-grade polyethylene (PE) paipa e tutusa le lautele ma le paipa uʻamea pe a uma ona aveese ivi uʻamea.Ole mafiafia ole laiga polyethylene e tatau ona fetaui ma le tulaga HG / T 20538-2016.
Avanoa o le Fa'aaogāga
(Siosiomaga Puipuiga) Lined palasitika paipa uʻamea tekinolosi laina palasitika paipa uʻamea tuufaasolo le lelei o paipa uʻamea ma paipa palasitika, ma e tusa ai ma le manaoga maketi, faagasologa gaosiga, faiga e tetee atu i le corrosion, sootaga, tau-lelei ma le tele o isi vaega o le talafeagai. mamanu ole paipa ina ua mae'a su'esu'ega atoatoa.O le mea lea, o le paipa e tele uiga faʻapitoa, faʻaaogaina lautele i ituaiga uma o fale malulu ma vai vevela.O le auala fesoʻotaʻiga o loʻo i ai le fesoʻotaʻiga mama pipii faʻapitoa, fesoʻotaʻiga (pili) poʻo le fesoʻotaʻiga uaea, o le faʻagasologa o le fausiaina e tutusa ma le fesoʻotaʻiga o le paipa uamea ma le fesoʻotaʻiga uaea.
Faatasi ai ma le lauiloa o le malamalama o tagata i le puipuiga o le siosiomaga ma le soifua maloloina, o paipa vai fou o le siosiomaga e puna mai e pei o pupu o le timu, ma e tele naua ituaiga e faitaulia.Laina palasitika paipa uʻamea tofi le lelei o paipa uʻamea ma palasitika paipa, ae lafoai o latou le lelei.O se tasi o mea e sili ona taua i totonu o le mamanu paipa o le fuafuaina lea o le mafiafia o le puipui o le paipa e tusa ai ma tulaga ma manaʻoga o le faʻaaogaina, ma o lenei parakalafa e aʻafia ai le tau o le oloa.Le mamanu mafiafia puipui tulaga ese o laina palasitika paipa uʻamea aofia totonu palasitika paipa puipui mafiafia ma fafo uelo puipui puipui, lea e fuafua ai se faasologa o uiga faapitoa:
1. O le tele o faʻaoga, faʻamatalaga atoatoa ma ituaiga;
2. Tekinolosi gaosiga tulaga ese;
3. Fa'alagolago ma vave feso'ota'iga faiga;
4. o le puipuiga o le corrosion i luga e fua lelei, matagofie;
5. le mamanu mafiafia puipui paipa i fafo e talafeagai;
6. O le mafiafia o le puipui o le paipa palasitika totonu e talafeagai e faʻamautinoa ai le lautele;
7. fa'asaoina o le malosi ma le puipuiga o le si'osi'omaga, atina'e tele;
Palasitika pa'u pa'u uamea, ua ta'ua fo'i o paipa fa'apipi'i palasitika, uamea-palasitika paipa tu'ufa'atasi, palasitika fa'apipi'iina paipa u'amea tu'ufa'atasi, o se paipa u'amea e pei o le matrix, e ala i le fufuluina, ta'avale, fufui, fa'asusu faiga i le paipa uamea (paipa pito i lalo) totonu. pito i luga o se vaega o palasitika fa'a'a'ala'au fa'a'au'au po'o totonu ma fafo o le paipa u'amea tu'ufa'atasi.O paipa u'amea palasitika fa'apipi'iina e lelei tele le fa'a'ele'ele ma le la'ititi la'ititi.Epoxy resin ufiufi palasitika paipa uʻamea e talafeagai mo le tuʻuina atu o le vai ma alavai, vai sami, vai mafanafana, suauʻu, kesi ma isi faʻasalalauga felauaiga, PVC faʻapipiʻiina paipa uʻamea e talafeagai mo alavai, vai sami, suauʻu, kesi ma isi felauaiga ala o faasalalauga.
Uiga o oloa
O paipa u'amea fa'apipi'i e faia i le PE (modified polyethylene) mo le palasitika vevela po'o le EP (epoxy resin) mo oloa fa'alava i totonu ma fafo, fa'atasi ai ma le fa'afefeteina lelei.I le taimi lava e tasi, o le ufiufi lava ia o loʻo i ai foi le faʻaogaina lelei o le eletise, e leai se eletise eletise.Le maualalo o le vai, malosi faʻainisinia maualuga, faʻalavelave faʻalavelave laʻititi, e mafai ona ausia le faʻamoemoega o le faʻaaogaina umi.E mafai fo'i ona puipuia lelei le fa'aleagaina o a'a o la'au ma le fa'alavelave o le si'osi'omaga o le palapala.Feso'ota'iga faigofie ma tausiga faigofie.
Tulaga Lelei
1. Fetuuna'i i le tanumia ma le susū si'osi'omaga, ma e mafai ona tatalia le maualuga ma le maualalo o le vevela.
2. Malosi fa'alavelave fa'alavelave, pe a fa'apipi'iina fa'alava uamea e pei o lima uaea, e mafai ona puipuia lelei fa'alavelave fa'ailo i fafo.
3. Malosiaga lelei, mamafa maualuga e oʻo atu i le 6Mpa.
4. Lelei le fa'aogaina o le fa'aogaina, e pei o se fa'ainitaneti puipuia o le uaea o le a le tupu lava le leakage.
5. Leai se burr, puipui lamolemole paipa, talafeagai mo le fausiaina o le taimi e ofuina uaea po o uaea.
