Pipa u'amea fa'apa'u PE Mo le fa'asaoina o le vevela
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 le pito i fafo ma totonu o mea e lua itu tu'ufa'atasi thermoplastics. 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 fa'afou fa'atekonolosi 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
Maualuluga mama mama ma maualuga maualuga
O le u'amea uamea fa'apipi'i paipa tu'ufa'atasi e maualuga le mama mama ma maualuga ma'a'a latalata i paipa u'amea, ma e sili ona talafeagai mo le fa'aulu pito ala o paipa.
Saogalemu faatinoga
O le faʻavaa faʻamalosia o le paʻu uʻamea faʻapipiʻi paipa faʻapipiʻi palasitika ma mea faʻapipiʻi palasitika аге atoa atoa i totonu o le upega tafaʻi, ma o loʻo i ai le popole i le paʻu ese o le palasitika puipui totonu ma fafo ma le faʻavaa uʻamea. O le fesoʻotaʻiga eletise eletise o loʻo i ai le malosi o le teteʻe atu i ata axial, ma o le pipeline system e maualuga le faʻatuatuaina. I lalo o tulaga masani, o le ola tautua e mafai ona oʻo i le 50 tausaga.
