DIN 30670-1ni uburyo bwo gusohora ibintu bugizwe n'ibice bitatu butanga polyethylene (3LPE) gusiga ku buso bw'ingufu zisutswe mu buryo bw'uburebure cyangwa mu buryo bw'umwuka noimiyoboro y'icyuma idakora nezakugira ngo bibarinde ingese.
Ikoreshwa cyane cyane mu miyoboro itwikiriwe cyangwa iri munsi y'amazi mu gutwara ibinyobwa cyangwa imyuka.
Icyitonderwa: DIN 30670 yagabanyijwemo ibice bibiri mu ivanjiri iheruka ya 2024 bitewe n'uburyo ikorwa, ari byo DIN 30670-1 itwikira imiyoboro n'imyenda ya polyethylene yangiritse, na DIN 30670-2 itwikira ubwoko bwa sintered n'ubwa sprayed fire.
Bigabanyijemo ubwoko bubiri hakurikijwe ubushyuhe bw'igishushanyo, aribwoubwoko bwa N na S.

Urwego rwa mbere rw'ururabo rwa epoxy, ifu ya epoxy resin igomba gukoreshwa.
Icyiciro cya 2 cyo gufatana, gishobora kuba ifu cyangwa gitwikiriwe.
Icyiciro cya gatatu cy'urwego rwa polyethylene, inzira yo gusohora imiyoboro, cyangwa inzira yo gusohora imiyoboro.
Gusohora umuyoboro w'amazi:
Muri ubu buryo, ibikoresho bya polyethylene bisohoka mu buryo butaziguye mu ishusho y'umuyoboro ukomeza, hanyuma bigashyirwa ku muyoboro w'icyuma.
Ubu buryo busanzwe bukoreshwa ku miyoboro mito y'umurambararo kandi butuma irangi ringana kandi rigakomeza.
Gusohora umuyaga:
Muri ubu buryo, polyethylene isohoka mu buryo bw'agace hanyuma igashyirwa hejuru y'umuyoboro w'icyuma.
Ubu buryo bukwiriye imiyoboro minini cyangwa idafite ubunini busanzwe kandi butuma habaho gusiga irangi ryoroshye ku miyoboro ikomeye cyangwa minini.
Bitewe n'ibyo umushinga ukeneye byihariye, hari ubundi buryo bwo kurinda ikoranabuhanga bushobora kongerwa kuri 3LPE.
Ibikoresho bikunze gukoreshwa birimobeto(reba ISO 21809-5),plastiki ikozwe mu kirahure ikoresheje fibre, cyangwa sima(reba DN N 30340-1).
Kugira ngo habeho imbaraga zo gukata neza, ni ngombwa gukaraba cyangwa gushyira igitutu ku buso bwa polyethylene.
Uburyo nk'ubwo bwo kuvura bufasha kongera uburyo bwo gufatana hagati y'urwego rw'inyongera rwo kurinda n'igitambaro cya polyethylene.

Ubunini bwose bwo gutwikira
Bitewe n'umurambararo w'umuyoboro w'icyuma, ubugari bw'urwego rwo kurinda ingese buzatandukana.
Ku bunini bwose bw'urwego rwa 3LPE, DIN 30670-1 igabanya ibyiciro bitatu kugira ngo ihuze n'ibisabwa mu bwubatsi bitandukanye.n,v, na s.
Icyiciro cya No: Ku bihe bisanzwe, ubunini bwa grade n busanzwe burahagije.
Ku bijyanye no gusiga polyethylene, ubugari bwa mm 1 bukoreshwa cyane cyane mu kurinda ingese, mu gihe ubugari busigaye bukoreshwa mu kongera ubushobozi bwo gutwara imizigo bw'urwego rwo kurinda.
Icyiciro cya v: Iyo umutwaro w’imashini wiyongereye (ubwikorezi, ububiko, gushyiramo, ubwiza bwihariye, ibisabwa byiyongera), ubugari bw’igitambaro bugomba kongerwaho 0.7 mm, ni ukuvuga v = n + 0.7 mm.
Icyiciro cya s: Ubunini bwihariye bwo gusiga hejuru ya v nabwo bushobora kumvikanaho kugira ngo buhuze n'ibyo umushinga runaka ukeneye, kandi ubunini nk'ubwo bwo gusiga bwanditseho Grade s.

Kugira ngo umenye uburebure, pima uhereye ku mizi y'umuyoboro kugeza ku ntangiriro y'inyuma y'urukuta rw'urwego rurinda ingese.

ISO 21809-1: By'umwihariko ku byerekeye polyethylene na polypropylene (3LPE na 3LPP) byo hanze bifite ibyiciro bitatu byo gusiga ku miyoboro y'icyuma ikoreshwa mu buryo bwo kohereza ibintu mu nganda za peteroli na gaze.
CSA Z245.21: Igaragaza irangi ryo hanze rya polyethylene rirwanya ingese ku miyoboro y'icyuma ikoreshwa mu buryo bwo gutwara ibintu.
AWWA C215: Irangi ryo hanze rya polyethylene rirwanya ingese rikwiriye imiyoboro y'amazi. Nubwo rikoreshwa cyane mu gutwara amazi, rifite byinshi rihuriyeho na DIN 30670 mu bijyanye n'ibikoresho n'ikoranabuhanga ryo kuyakoresha.
Twiteguye gukorana namwe mu gutanga imiyoboro y'icyuma myiza cyane hamwe n'ibisubizo byo kwirinda ingese ku mishinga yanyu. Twandikire kugira ngo ubone ibisobanuro birambuye ku bicuruzwa byanyu, twishimiye kubafasha kubona uburyo bwiza bwo gukoresha imiyoboro y'icyuma bujyanye n'ibyo mukeneye!
