DIN 30670 e faʻatatau i polyethylene coatings i luga o paipa uʻamea ma mea faʻapipiʻi–Manaoga ma su'ega.

O lenei tulaga o loʻo faʻamaoti mai ai manaʻoga mo faʻaoga faʻapipiʻi tolu-laupapa faʻapipiʻiina polyethylene faʻapipiʻi faʻapipiʻi, ma tasi pe faʻapipiʻi faʻapipiʻi faʻapipiʻi polyethylene faʻapipiʻi faʻapipiʻi mo le puipuia o le pala o paipa uʻamea ma mea faʻapipiʻi.O coatings e talafeagai mo le puipuiga o le tanumia po o le goto ifo o paipa uamea i le vevela mamanu o–40 °C e oʻo atu i le +80°C. O le tulaga o lo'o iai nei o lo'o fa'amaoti mai ai mana'oga mo fa'alavalava e fa'aoga i aiLSAW paipa uamea or paipa u'amea lamolemole mamea fa'apipi'i fa'aaogaina mo le fausiaina o paipa mo le felauaiga o vai po'o kasa.O le faʻaogaina o lenei tulaga faʻamautinoaina o le PE faʻapipiʻiina e lava le puipuiga mai le masini, vevela ma vailaʻau o loʻo tutupu i le taimi o le gaioiga, felauaiga, teuina ma le faʻapipiʻiina.DIN EN ISO 21809-1 o loʻo faʻamaoti mai manaʻoga i tulaga faʻavaomalo mo le tolu-layer extruded polyethylene- ma polypropylene-faʻavae faʻapipiʻi mo paipa uʻamea mo le suauʻu ma paipa kesi masani auala felauaiga.O vaega nei ole talosaga e le o aofia ile DIN EN ISO 21809-1:─faʻapipiʻi uma polyethylene mo paipa uʻamea ma mea faʻaoga e faʻaaogaina mo le felauaiga ma le tufatufaina o vai ma vai otaota,─faʻapipiʻi uma polyethylene mo paipa uʻamea ma mea faʻapipiʻi i laina paipa mo faʻasalalauga kasa ma vai,─tasi-ma multi-layer sintered polyethylene-faʻavae coatings mo paipa uʻamea ma mea faʻaoga faʻaoga mo paipa felauaiga ma paipa tufatufaina O le tulaga o loʻo i ai nei e tumau pea le aoga mo vaega o loʻo i luga o le faʻaogaina.E lua-laupapa polyethylene faʻavae faʻapipiʻi faʻasalalau i tulaga Europa i le DIN EN 10288 lea na lomia ia Tesema 2003.

O mea e tatau ona filifilia i le faitalia a le coater aua, e faʻatatau i le faʻapipiʻiina ma le faʻapipiʻiina o faʻagasologa, e mafai ona faʻaogaina mea eseese e faʻamalieina ai manaʻoga maualalo o loʻo faʻamaonia i lenei tulaga mo le faʻamaeʻaina.So'o se mana'oga fe'avea'i a le fa'atau e fa'atatau i mea e fa'aaogaina e tatau ona i lalo o le maliliega. E tatau ona saunia le pito i luga e ala i le aveeseina o le 'ele e ala i le fa'amama fa'a.O le fa'amamāina o le pa ma so'o se galuega e mana'omia mulimuli ane e le tatau ona fa'aitiitia ai le mafiafia aupito maualalo o puipui o lo'o fa'amaoti mai i tulaga fa'atekinisi mo le paipa u'amea.E tatau ona aveese le pefu o totoe a'o le'i ufiufi.
