Fa'atatauga
O le paipa fa'apipi'i polyethylene u'amea fa'apipi'i e fai i le u'amea u'amea malulu ma le thermoplastics e fai ma mea mata, ma o paipa u'amea manifinifi puipui e fau mai i le argon arc butt welding po'o le plasma spiral welding e fa'aaogaina e fa'amalosi ai.O apa i fafo ma totonu o mea fa'apipi'i tu'ufa'atasi lua itu.O se ituaiga fou o paipa mamafa tu'ufa'atasi, Ona o le porous manifinifi-pa puipui uamea fa'amalosia paipa ua afifiina i le thermoplastic faifai pea, o lenei paipa tu'ufa'atasi e le gata e faatoilaloina le faaletonu ta'itasi o paipa u'amea ma paipa palasitika, ae o loʻo i ai foʻi le rigidity o paipa uʻamea ma le corrosion. tetee o paipa palasitika.O se vaifofo mo fale suau'u ma vaila'au.O se paipa fa'anatinati mana'omia o paipa maa'a tetele ma le vaeluagalemu i totonu o fanua o vaila'au, mea'ai, mining, kesi ma isi fanua.Ose foi suiga fou faatekinolosi ausia e foia ai le paipa autu o le fausiaina ma le sapalai o le vai.Ole ituaiga fou ole paipa tu'ufa'atasi ile 21stseneturi.
Vaega
Malosi maualuga ma faʻalauteleina laina laina.
Ona o le faʻamalosia o le faʻavaa uʻamea, o le paʻu uʻamea faʻapipiʻi palasitika paipa tuʻufaʻatasia e maualuga atu le malosi, maualuga maualuga ma aʻafiaga e tetee atu nai lo le paipa palasitika.I le taimi lava e tasi, o le a'afiaga o le fa'avaa u'amea e fa'apena ai fo'i le fa'apa'u uamea fa'apipi'i palasitika paipa e maua ai se laina maualalo e tutusa ma le paipa uamea.Fa'atelega fa'atele ma le fa'asao.
Tete'e ma le ofuina.
Ole mea ole polyethylene maualuga ua filifilia mo le paipa fa'apipi'i palasitika palasitika fa'apipi'i ose mea fa'amea fa'akomepiuta e le-polar ma fa'amautu mea fa'a-kemikolo, e tetee atu i le tele o vai, masima alkali ma ala fa'aola, ma fa'amea eletise eletise.O le faʻatinoga o le oloina e 5 taimi maualuga atu nai lo paipa uʻamea.
