Umuyoboro wa polyethylene (PE pipe) ni umuyoboro w’ipulasitike ukozwe ahanini mu nzira ya polyethylene biciye mu nzira yo gusohora. Kubera ko imiyoboro ya PE ifise ubushobozi bwiza cane bwo guhindura ibintu, ikoreshwa cane mu gutanga amazi no mu gukura amazi, mu gutanga gazi, mu gufumbira uburimyi, no mu gutwara amazi y’inganda. Iki kiganiro kizovuga mu buryo burambuye ibiranga cane imiyoboro ya PE n’ivyiza biyigira mu bikorwa vy’ukuri.
1. Iremereye kandi Ikomeye-Ikomeye, Biroroshe Gushiramwo no Gutwara
Amatiyo ya PE afise uburemere buke, hafi 0,94-0,97 g/cm3, ari hasi cane y’amatiyo y’ivyuma, gutyo akagaragaza ibiranga uburemere buke cane. Ivyo bituma amatiyo ya PE yoroha gutwara no gushiramwo, bikaba bigabanya cane amafaranga y’abakozi n’ay’ibikoresho. Muri ico gihe nyene, naho uburemere bwayo buke, imiyoboro ya PE irafise ubushobozi bwinshi bwo gukomera no guhangana n’ibintu bikomeye, ishobora kwihanganira inguvu zimwe zimwe zo hanze zitavunitse bitagoranye, ivyo bikaba bituma uburyo bw’imiyoboro bugumaho igihe kirekire.
2. Ubushobozi bukomeye bwo guhangana n’ugusenyuka n’ubuzima buramba
Amatiyo ya PE arafise ubushobozi bwiza cane bwo gukomera, ntashobora gusenyuka kubera aside zitandukanye, alkali, umunyu be n’ibintu biva mu binyabuzima, ivyo bikaba bituma ashobora gukoreshwa mu bidukikije bitandukanye bikomeye, nk’ubutaka, amazi yo mu butaka be n’amazi mabi yo mu nganda. Ugereranije n’imiyoboro y’ivyuma, imiyoboro ya polyethylene (PE) ntiyigera ibora, ntiyigera igira ububabare canke ngo ibe n’ubumara bw’umuyagankuba, gutyo bikaba bituma ikintu gitwara kigira ubusuku. Ikindi kandi, amatiyo ya PE arafise ubushobozi bwiza cane bwo kurwanya-ugukura, afise ubuzima bw’imyaka irenga 50 iyo akoreshwa mu buryo busanzwe, bikagabanya cane amahera yo kwitaho no gusubirira.
3. Guhinduranya neza, Guhinduranya ahantu hatoroshe
Amatiyo ya PE arafise ubushobozi bwiza cane bwo guhinduranya, akajanye n’ibisabwa vyo gushiramwo ibintu bitandukanye. Ugereranije n’imiyoboro ikomeye (nk’imiyoboro y’icuma n’iy’icuma), imiyoboro ya PE ntikunda gusaduka iyo ipfutse, ivyo bikaba bituma ishobora guca mu ntambamyi ikoresheje ubushobozi bwayo bwo guhinduranya, bikagabanya igitigiri c’ibikoresho vy’imiyoboro bikoreshwa no kworohereza ubwubatsi. Ikindi, amatiyo ya PE arafise ubushobozi bukomeye bwo guhangana n’ugutera, akaguma afise ikidodo ciza n’ubutungane bw’imiterere mbere no mu bice bikunda kubamwo ibikorwa vy’ubutaka (nk’ubutaka buyoroshe n’aho haba umutingito).
4. Uruhome rw'imbere ruryoshe, rushobora guhangana n'amazi make
Uruhome rw’imbere rw’imiyoboro ya PE ruraryoshe cane, rufise ububabare buri hasi cane y’ubw’imiyoboro y’ivyuma n’iya beton. Ku bw’ivyo, ubushobozi bw’amazi ari mu muyoboro bwo guhangana n’ugutemba burake, ivyo bikaba bigabanya neza inguvu zitakazwa mu gihe co gutwara. Ico kiranga gituma imiyoboro ya PE ikora neza cane mu gutanga amazi, mu gutanga gazi, no mu bindi bikorwa, kandi irabereye cane cane ku mirongo y’imiyoboro y’urugendo rurerure-. Vyongeye, uruhome rw’imbere ruryoshe ruragabanya ukuntu ibintu bishobora kwifatanya n’ibindi, rugabanya ingorane zo gufunga, kandi ruratuma iyo tiyo imara igihe kirekire.
5. Bidahungabanya ibidukikije kandi bitekanye, bihuye n’ivyo abahinga bo muri iki gihe bakeneye
Amatiyo ya polyethylene akozwe mu bikoresho vya polyethylene bitagira ubumara kandi bitagira akamoto, bihuye n’ingingo ngenderwako z’igihugu zijanye n’isuku ry’amazi yo kunywa kandi bibereye gutwara amazi yo mu rugo n’ibifungurwa-vy’agaciro. Ico gihe nyene, uguhingura imiyoboro ya polyethylene bikoresha inguvu nke cane kandi birashobora gusubirwamwo, bikaba bihuye n’ingingo ngenderwako zo kurinda ibidukikije. Mu bijanye no gutanga gazi, imiyoboro ya polyethylene irafise ubushobozi bwiza cane bwo gukingira umwuka, igakingira neza gazi gusohoka kandi igatuma gutanga gazi igira umutekano mwiza.
Mu ncamake, imiyoboro ya polyethylene, kubera uburemere bwayo buke, ikomeye cane, idashobora gusenyuka, ishobora guhinduka neza, uruhome rw’imbere ruryoshe, kandi idakingira ibidukikije, irafise ikibanza gihambaye mu bijanye n’ubuhinga bw’imiyoboro bwo muri iki gihe. Kubera ko ubuhinga bw’ibikoresho buzobandanya gutera imbere, ubushobozi bw’imiyoboro ya polyethylene buzorushiriza gutera imbere, kandi n’aho ikoreshwa buzorushiriza kuba bwagutse, bigatuma iba ihitamwo rihambaye mu bijanye n’ubwubatsi bw’imiyoboro muri kazoza.
