Pipa u'amea fa'apa'u PE Mo kesi
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
Fa'atinoga tumama
O le fa'asinomaga o le tumama ma le saogalemu o le paipa palasitika fa'apipi'i fa'apipi'i e fetaui ma mana'oga o le GB9687 "Tulaga tumama mo le Polyethylene Molded Products for Food Packaging" ma le GВ/Т17219 "Saogalemu Tulaga Fa'avasegaina mo Mea Fa'asoa Suavai inu ma Meafaigaluega ma Mea Puipui". O le mea sili e suitulaga i paipa u'amea ma paipa u'amea.
puipui malu totonu ma ta'amilosaga faatinoga
O le puipui i totonu o le mata uamea fusipa'u palasitika paipa tu'ufa'atasi e matua lamolemole, ma o le roughness atoatoa e na o le 1/20 o le paipa uamea.O le faʻaogaina o le gafatia i lalo o tulaga tutusa e tusa ma le 30% maualuga atu nai lo le paipa uʻamea.
