FDPE Pipe vs PE Pipe: Ivyo Amajambo Asobanura
Umuyoboro wa PE n'umuyoboro wa HDPEni kenshi ikibazo c’amajambo.PEidondora umuryango w’ivyuma vyitwa polyéthylène, mu gihe .HDPEni urugero rw'uburemere burengeye -muri PE rusanzwe rugaragazwa cane ku mirongo y'amazi y'umuvuduko. Mu yandi majambo, "imiyoboro y'umuvuduko wa PE" myinshi ikoreshwa mu mazi no mu mirongo y'amazi mu vy'ukuri ikozwe mu bice vy'ivyuma vy'ivyuma vy'ivyuma vy'ivyuma vy'ivyuma.
Umuntu aravye amasoko, ikintu gihambaye si ikimenyetso ahubwo ni .Igitigiri c'amavuta n'ugushira mu migwi ibikorwa. Nk’akarorero, umugambi woshobora gusaba umugwi w’ibikoresho vyihariye nk’PE4710(ikunda kuvugwa muri Amerika y’Uburaruko) kuko yerekana igihe kirekire-ubushobozi bw’inkomezi z’amazi kandi ishigikira ivyigwa vy’umuvuduko munini ku SDR yatanzwe. Ivyo ni vyo bituma kandi igisomwa kivuga gusa ngo "umuyoboro wa HDPE" gishobora kuba kidatunganye-abaguzi mu bisanzwe bakeneye urugero rw'ivyuma, SDR, n'ingingo ngenderwako kugira ngo basuzume ukuntu bingana.
Kuri iyi paji, igikoresho ni umuvuduko-ugereranywa n'uburyo bwa HDPE/PE bujanye n'ingingo ngenderwako rusangi z'ibikorwa vy'amazi nk'ASTM D3035, ASTM F714, kandiAWWA C906. Ivyo bipimo bisobanura ingene umuyoboro ugereranijwe, ugeragezwa, ushirwako ikimenyetso, kandi ukarekurwa-ku buryo "PE vs HDPE" iba ingingo ikora ku bijanye n'kwubahiriza + igipimo c'umukazo + inyandiko zishobora gukurikirana, aho kuba izina ryo kwamamaza.
PE Pipe vs PPR: Uko wohitamwo hakurikijwe igikorwa
KuberaPE umuyoboro vs PPR, ingingo ikunda kuba ijanye n’ubushuhe bw’ibikorwa n’uburyo bwo gushiramwo: PE umuyoboro w’umuvuduko urakunda gutorwa ku bijanye n’imiyoboro y’ugusangira ihambwe n’imigenderanire miremire yo hanze (fusion-ifatanye, inyigisho-yihanganira), mu gihe PPR ikoreshwa cane mu kwubaka amazi ashushe/akanye n’imigenzo itandukanye yo gufatanya (SO14). ryerekezwa ku mirongo ya PPR). Ubanze uhuze ibikoresho n’igikorwa, hanyuma wemeze ivy’ugufatanya n’ivyemezo imbere yo gusaba.
Ni igiki HDPE pipe ikoreshwa?
Amatiyo ya HDPE akoreshwa cane ku nzira z’amazi zikoreshwa n’inguvu kubera ko aguma yizigirwa mu bihe nyavyo vy’aho hantu bikunda gutuma habaho amazi: imigende miremire, gufatanya kenshi, n’ibice bibona ukwimuka gutoyi kuva ku ntumbero canke ku gutwara ibintu. KuUburebure bwo gusubiramwo ubutegetsi bwo mu mahanga muri Dubai (Emirats Arabes Unis), uwo muhinga yasubiriye umusaza .DN200-DN400gukwiragiza ibintu vyinshi ku ruhande rw’inzira aho igikorwa cari kigarukiye kuijoro-amadirisho y'ihindukan'umurongo ukomeye-gusubira gufungura ibihe vy'iherezo. Inyungu y'ibikorwa ntiyari "ipulasitike n'icuma" mu vyiyumviro-yari iyobutt-ingingo zifatanyen’ugugabanya ivyuka vy’ubuhinga mu gihe c’igerageza ry’umuvuduko w’ibice, rero gutanga ibikorwa vyari gushobora gutera imbere igice-ku-igice ata gukurikirana ivyuka bitobito ku bifatanya inyuma y’ugusubiramwo. Ku bw’ubwo bwoko bwa porogarama, Octal Pipe mu bisanzwe itanga umuyoboro nk’ibintu vyasobanuwe (ubunini + SDR + umugwi w’umuvuduko) ufise ikimenyetso gitomoye, ku buryo QA y’aho hantu ishobora guhuza inyandiko y’igerageza ry’umuvuduko n’ivyo vyashizweho.
HDPE pipe nayo itoranywa igihe uburyo bwo gushiramwo bujana ingingo y’ibikoresho. KuIgikoresho co kujabuka HDD hafi y’igisagara ca Rotterdam (Ubuholandi)ku murongo mugufi wo gukura amazi munsi y’umugende, uwukora amasezerano yari akeneye gukomeza gukurura-mu mugozi ufise ubugenzuzi bwa OD bushobora gutegekanirwa kugira ngo umuyoboro ushobore guca mu bipimo no kuyobora neza amabarabara mu gihe co gusubira inyuma, ata gutera canke gusubira gukora ku nguvu ku mwobo wo kwinjira. Iryo tsinda ryafunze urugero imbere nk'uko "ingano + SDR + uburyo bwo kwifatanya," ran fusion ikoresheje ibipimo vyanditswe kugira ngo umuntu ashobore gukurikirana, kandi yibanze ku bijanye n’ugusuzuma amabuye hamwe n’ukwemera hydrotest-aho gucungera amajoints y’indodo/y’ibara ry’agahama imbere mu mfuruka y’uruzitiro aho ukuronka bike kandi gusana bitwara amahera menshi.
Ugukwirakwiza gazi bivuguruwe n'amahuza y'ibikorwa (gazi-ivy'ukubahiriza amategeko):
Gazi y'imiyoboro ya HDPEibisabwa bigenwa n’ingingo mfatirwako zitandukanye n’ubwenge bwo kwemera kuruta imirongo y’amazi yo kunywa. Ku bijanye no gutanga/gukwiragiza gazi y'amavuta, ibisobanuro bikunze gukoreshwaASTM D2513na/cankeISO 4437 / RU 1555(bivanye n’akarere n’ibisabwa n’umukoresha). Igihambaye co kugenzura amasoko ni ugusubiramwo no kwemeza neza ko umuyoboro ari "igikorwa ca gazi" (itegeko + urugero + ikimenyetso + urugero rw'igerageza), aho kwiyumvira ko icemeza ko amazi-urugero rwa PE gishobora gusubira gukoreshwa.
HDD/ibijabuka bitera ubwoba aho umugozi wo gukurura ukomeza usabwa:
Ku bijanye n’ugujabuka umugende wa Octal Pipe HDD, uwo muhinga yari akeneye umugozi muremure ubandanya ufise OD ihamye kugira ngo ushobore guca ku bipimo vy’ibiziga no kuyobora neza amabarabara. Iryo tegeko ryari rifunzwe nk'"ubunini + SDR/umugwi w'umuvuduko + uburyo bwo gufatanya," kandi QA yo mu murima yibanze ku mirongo y'ugufatanya, isuzuma ry'amabuye, n'igerageza ry'amazi-aho gucunga amahuriro menshi y'ubuhinga imbere mu mfuruka.
Guhindura umuntu amajambo 134
Ku bijanye n’ugugura, urufunguruzo ni ugugura umuyoboro wa HDPE nk’uburyo: wemeze igikorwa (amazi vs gazi), hanyuma usobanureOD/urutonde rw'ubunini, SDR/umugwi w'umuvuduko, urugero rw'ivyuma aho bisabwa, n'urugero/uburyo bwo gukorana. Ukwo ni kwo gutandukanya hagati y'ugusohora ahantu heza n'akazi kahagaze kubera ko umuyoboro ari "PE" mw'izina ariko ntujanye n'umugwi w'umuvuduko, uburyo bwo gufatanya, canke inyandiko umugenzuzi yiteze.
Umurongo wo guhingura imiyoboro ya HDPE n'ukwizera uburyo
Uburyo bwo gukora imiyoboro ya HDPE
Ivyo gukora imiyoboro ya HDPE bitangura no gusohora ivyuma vy’isugi vy’uburemere bwinshi, bifise uburemere bw’amamolekule bubiri mu bice vya PE4710 kugira ngo bikomeze kandi bishobore guhangana n’ugusaduka. Inyuma y’ugusohoka, amatiyo arageragezwa cane n’amazi ku AWWA C906 ku ncuro 1,5 z’urugero rw’umuvuduko, hamwe n’ugusuzuma n’amajwi kugira ngo hasuzumwe ko uruhome ruhuye no kumenya ko hariho utunenge twose. Ivyiyumviro vy’ugucungera uburyo bwose bishiramwo ukumenya neza ibikoresho (PMI), ukugenzura neza ingero, n’igerageza ry’uguturika kugira ngo hamenyekane ubutungane bw’imibumbe. Ivyemezo vy’igerageza ry’insyo (MTC ku EN 10204 3.1) bitanga amakuru arambuye y’ibice vy’ivyuma, ibipimo vy’ugusohora, n’ibisubizo vy’igerageza ritagira -ugusambura (NDT), mu gihe igenzura ry’uwundi muntu rivuye mu bigo nka SGS canke BV riboneka bitagoranye kugira ngo umuntu agire icizigiro congereweko.
Kwemera umurima imbere yo gusubira kwuzuza (kubera iki uhitamwo umuyoboro w'umunani)
Imigambi myinshi y'imiyoboro ya HDPE nticerezwa kubera ko "PE irakomeye"-icerezwa kubera ko imbere y'akazi idashobora gusubira kwuzuza gushika umugenzuzi ashobora gufunga urutonde rw'ivyemezo. Octal Pipe ifata PE nk'gusohora-ububiko bwiteguyeyubatswe hirya no hino y’ingene imigende mu vy’ukuri igenda: ibibanza vyo gutanga, igikorwa co gukorana, n’ibice vyo gupima amazi bitegerezwa gushirwa ku murongo kugira ngo umugwi w’aho hantu ushobore kwemeza ko vyubahiriza amategeko vyihuta, atari inyuma y’aho umuyoboro umaze gushika hasi.
- Fusion-yibanze ku kwemera infashanyo:PE ibikorwa biba mu nsanganyamatsiko. Ku migambi ishaka gucungera neza, Octal Pipe ihuza urugero rw’ugutanga n’ugushirwa mu ngiro kw’akazi mu kwemezauburyo bwo gufatanya (ugufatanya kw'igitsina / ugufatanya kw'amashanyarazi), guhuza, n'uburyo bwo kwemeraimbere, rero ibitabo vy'abakozi n'ibimenyetso vy'imigwi bishobora gusubirwamwo bishingiye ku rugero rwiza ata "buryo butari bwo bw'ibikoresho" bitangaje.
- Igerageza ry'amazi imbere yo gushiramwo:Turasunika indero yoroshe y'amasoko: gusobanuraimbibe z'ikigeragezo, igihe co gufata, n'ingingo zo kwemerakare (kandi ukabirungika mu mafaranga ashigikira uwo mugambi). Ivyo bibuza igikorwa co gusubira gukora mu gihe c'inyuma aho igice kigomba gusubira kugeragezwa kubera ko ibikoresho n'itegurwa ry'ikigeragezo bitahuye.
- Uguhuza uruhome n'ukwizigirwa kw'umukazo:Ibikorwa vy'umukazo bishingiye ku guhingura-, ariko ukwizigirwa kw'itongo kuva ku kugenzura uruhome ruhamye no gusohora gusukuye. Ku bijanye n’amazi n’imirongo ya HDD, dushimika ku guhuza uruhome kugira ngo tugabanye ibice bigoyagoya bihinduka ibitangaza vy’igerageza ry’amazi.
- Uburinzi bwo ku ruhande no ku gukoresha bukingira ivyonona vyihishije:Gouges n’ibikomere bikomeye birashobora kuba ibibanza vyo kwanka imbere y’uko umuntu asubira kwuzuza. Dukoresha uburyo bwo gupakira/uburinzi bwo gukoresha n’ubuyobozi bwo gukoresha kugira ngo amatiyo ashike n’inzira n’ibirego bike vy’ivyago n’ibice bike -outs ku kibanza.
