DIN 30670-1ni uburyo butatu bwo gukuramo ibintu butanga polyethylene (3LPE) gutwikira hejuru yuburebure cyangwa kuzunguruka kandiimiyoboro idafite ibyumakubarinda ruswa.
Ikoreshwa cyane cyane muri sisitemu yo gushyingura cyangwa yarohamye mu gutwara amazi cyangwa gaze.
Icyitonderwa: DIN 30670 yagabanijwemo ibice bibiri mubisohokayandikiro biheruka 2024 bitewe nuburyo byakozwe, aribyo DIN 30670-1 itwikiriye hose hamwe nigikomere cya polyethylene, naho DIN 30670-2 itwikiriye ubwoko bwatewe kandi bwaka umuriro.
Bagabanijwemo ubwoko bubiri ukurikije ubushyuhe bwubushakashatsi, aribwoandika N hanyuma wandike S..

naISO 21809-1bihuye nicyiciro A nicyiciro B, kimwe.
Igice cya 1 Epoxy resin layer, epoxy resin ifu igomba gukoreshwa.
Igice cya 2 gifatika, gishobora kuba ifu cyangwa ikozwe neza.
Igice cya 3 Polyethylene, inzira yo gukuramo imiyoboro, cyangwa inzira yo gusohora.
Tube Gukuramo:
Muri ubu buryo, ibikoresho bya polyethylene bisohoka mu buryo butaziguye mu buryo bukomeza, hanyuma bigahita byinjira mu cyuma.
Ubu buryo busanzwe bukoreshwa kumiyoboro ntoya ya diameter kandi ikanemeza uburinganire no gukomeza.
Gukuramo ibicuruzwa:
Muri ubu buryo, polyethylene isohoka muburyo bwumugozi hanyuma igakomeretsa hejuru yumuyoboro wibyuma.
Ubu buryo bubereye imiyoboro minini ya diametre cyangwa idafite ubunini-buke kandi itanga uburyo bworoshye bwo kwambara ku miyoboro igoye cyangwa nini.
Ukurikije ibyifuzo byihariye byumushinga, urwego rwinyongera rwo gukingira imashini rushobora kongerwa kuri 3LPE.
Ibikoresho bisanzwe bikoreshwa birimobeto(reba ISO 21809-5),ibirahuri bya fibre-bishimangira plastike, cyangwa sima ya sima(reba DN N 30340-1).
Kugirango ubone imbaraga zogosha neza, birakenewe gukomera cyangwa gukanda hejuru ya polyethylene.
Ubuvuzi nk'ubwo bufasha kongera ubwuzuzanye hagati yinyongera ikingira hamwe na polyethylene.
Epoxy Resin Umubyimba
Nibura 80um.
Umubyimba wububiko
Nibura 150um.
Ubunini bwuzuye
Ukurikije diameter nominal yumuyoboro wibyuma, ubunini bwurwego rwo kurinda ruswa bizaba bitandukanye.
Kubwubunini bwuzuye bwa 3LPE, DIN 30670-1 igabanya ibyiciro bitatu kugirango ihangane nibisabwa bitandukanye byubwubatsi.n, v, na s.
Icyiciro n: Kubintu bisanzwe, ubunini bwurwego n mubusanzwe burahagije.
Kubitwikiriye polyethylene, umubyimba wa mm 1 ukoreshwa cyane cyane mukurinda ruswa, mugihe umubyimba usigaye ukoreshwa mukuzamura imashini itwara imizigo yikingira.
Icyiciro v: Niba umutwaro wubukanishi wiyongereye (ubwikorezi, kubika, gushyira, ubwiza bwihariye, ibisabwa byiyongereye), umubyimba ntarengwa ugomba gutwikwa ugomba kwiyongera kuri mm 0.7, ni ukuvuga v = n + 0,7 mm.
Icyiciro s: Ubunini budasanzwe bwo gutwikira hejuru ya v burashobora kandi kumvikana kugirango buhuze ibikenewe byumushinga runaka, kandi ubunini bwikigero bwihariye bwanditseho Grade s.
150mm ± 20mm, inguni ya bevel yo gutwikira umubyimba ntigomba kurenza 30 °.
Ibice bya epoxy na adhesive bigomba gukurwaho byibura mm 80 uvuye kumuyoboro.Igice cya epoxy kigomba gusigara kiva mu muyoboro wa polyethylene ushyizwe ku mpera ya mm 10.
Kugirango umenye uburebure, bapima uhereye kumuzi yumuyoboro kugeza ku ntangiriro ya diagonal yaciwe impera yumurongo wo kurinda ruswa.

Ubuso bw'inenge kugiti cye bugomba gusanwa ntibugomba kurenza cm 10.Umubare wemewe w'inenge ugomba gusanwa ni inenge 1 kuri metero 1 z'uburebure.Bitabaye ibyo, umuyoboro ugomba kwandikwa.
ISO 21809-1: By'umwihariko kubice bitatu byo hanze bya polyethylene na polypropilene (3LPE na 3LPP) bifata imiyoboro y'ibyuma ikoreshwa muri sisitemu yo kohereza mu nganda za peteroli na gaze.
CSA Z245.21: Kugaragaza impuzu zo hanze za polyethylene anticorrosion kumiyoboro yicyuma ikoreshwa muri sisitemu ya convoyeur.
AWWA C215: Polyethylene yo hanze irwanya ruswa ikwiranye n'amazi yo gutanga amazi.Nubwo ikoreshwa cyane muri sisitemu yo gutwara amazi, ifite byinshi ihuriyeho na DIN 30670 mubijyanye nibikoresho nibikoresho byikoranabuhanga.
Dutegereje gufatanya nawe gutanga imiyoboro myiza yicyuma hamwe nigisubizo cyo kurwanya ruswa kubikorwa byawe.Nyamuneka nyamuneka kutwandikira kubindi bisobanuro birambuye, twishimiye kugufasha kubona uburyo bwiza bwo guhitamo ibyuma kubyo ukeneye!
