Kumyaka myinshi, isoko nini ya diameter (santimetero 16 no hejuru) isoko ryamazi ryamazi ryagaragajwe numuyoboro wibyuma (SP), Umuyoboro wa Precast Beton Cylindrical (PCCP), Umuyoboro wibyuma (DIP) na PVC (Polyvinyl Chloride).Kurundi ruhande, umuyoboro wa HDPE ufite 2% kugeza 5% byisoko rinini rya diameter.
Iyi ngingo igamije kuvuga muri make ibibazo byubwenge bifitanye isano na diameter nini ya HDPE hamwe nibyifuzo byo guhuza imiyoboro, fitingi, ubunini, igishushanyo, gushiraho, no kubungabunga.
Raporo ya EPA ivuga ko ibibazo byubwenge bikikije imiyoboro minini ya diameter ya HDPE bitetse kugeza ku ngingo eshatu zingenzi.Ubwa mbere, muri rusange habuze gusobanukirwa ibicuruzwa.Mu mishinga ya komine, umubare wabafatanyabikorwa urashobora kugorana guhererekanya ubumenyi kubicuruzwa bifitanye isano.Mu buryo nk'ubwo, abakozi bakunze gukoresha ibicuruzwa n'ikoranabuhanga bimenyerewe.Hanyuma, uku kubura ubumenyi birashobora no gutuma abantu bumva nabi HDPE idakwiriye gukoreshwa mumazi.
Ikibazo cya kabiri cyubwenge gikomoka kumyumvire yuko gukoresha ibikoresho bishya byongera ibyago, nubwo ubumenyi bumwe burahari.Abakoresha bakunze kubona HDPE nkigicuruzwa gishya kubikorwa byabo byihariye, hanze yakarere keza kuko nta burambe bafite.Umushoferi mukuru arakenewe kugirango yemeze ibikorwa byogukoresha ibikoresho bishya nibisabwa.Birashimishije kandi.
Inzira nziza yo gutsinda ibyo bibazo bigaragara ni ugufasha kugereranya ingaruka zishobora kugaragara no kwerekana inyungu zingana zo gukoresha ibikoresho bishya.Na none, birashobora gufasha kureba amateka yibicuruzwa bisa mukoresha.Kurugero, ibikorwa bya gaze karemano byakoresheje imiyoboro ya polyethylene kuva hagati ya 1960.
Nubwo byoroshye kuvuga kubyerekeye imiterere yumubiri nu miti ya pipine ya HDPE, inzira nziza yo gufasha kugereranya inyungu zayo ni ugusobanura imitungo yayo ugereranije nibindi bikoresho.Mu bushakashatsi bwakozwe ku bikorwa 17 by’Ubwongereza, abashakashatsi bagaragaje igipimo mpuzandengo cyo kunanirwa ku bikoresho bitandukanye.Impuzandengo yo gutsindwa kuri kilometero 62 yavuye kuri 20.1 kunanirwa kuruhande rwo hejuru rwumuyoboro wicyuma kugeza kunanirwa 3.16 kuruhande rwo hasi rwumuyoboro wa PE.Ikindi gishimishije cyagaragaye muri raporo nuko bamwe muri PE bakoresheje imiyoboro yakozwe hashize imyaka irenga 50.
Muri iki gihe, abakora PE barashobora gukora ibyuma byubaka bya polymer kugirango bongere imbaraga zo gukura buhoro buhoro, imbaraga zidasanzwe, guhindagurika, guhangayikishwa na hydrostatike, nibindi bintu bifatika.Akamaro k'iri terambere ntigishobora kuvugwa.Mu myaka ya za 1980 na 2000, ubushakashatsi bwibigo byingirakamaro byishimiye imiyoboro ya PE byahindutse cyane.Guhaza kw'abakiriya byagaragaye hafi 53% mu myaka ya za 1980, bizamuka kugera kuri 95% muri 2000.
Impamvu nyamukuru zo guhitamo ibikoresho byumuyoboro wa HDPE kumiyoboro minini yo gukwirakwiza diameter harimo guhinduka, guhuza ingingo, kurwanya ruswa, guhuza nuburyo bwa tekiniki butagira umwobo nko gutobora icyerekezo cya horizontal, no kuzigama amafaranga.Ubwanyuma, izi nyungu zishobora kugerwaho gusa mugihe uburyo bukwiye bwo kubaka, cyane cyane gusudira fusion.
