Igesi yemvelo isiwumthombo wamandla obalulekile ekuphileni kwansuku zonke kwezakhamuzi eziningi zasemadolobheni. Nokho, njengoba amapayipi egesi eba madala, nezingozi zokuphepha ziyanda. Izingozi zegesi ziye zenzeka ezindaweni eziningi emhlabeni , futhi eziningi zazo zihlobene nokuguga nokunganakwa kwemigudu yokuphehla igesi. Njengamanje ukuvuselelwa kwemigudu emidala yegesi kuyisihloko kakhulu ukukhathazeka, futhi le mibuzo iye yavela.
Ayini amapayipi egesi e-HDPE?
HDPE, okungukuthi isithuthi sasezulwini sokugcina amandla esihlangu, sibhekiswe kusukela ku-PE80, PE100, ne-PE4710 kumaketi yaseNtshonalanga yaseMeryka. Kunezinkinga zokubhala, ukuthabatha kwezinkimba, nokuthabatha kwezinkinga zokuphakama kwezinkinga, okunika ubuhle obuhle bokusebenza ngaphansi kwemvelo, futhi kwenza ukuthi i-HDPE ibe yisikhundla esiphambili sokugcina amandla esihlangu. Ipipe zasegas yaseBaishunxing ziyachazwa ngokulingana nezindlela zezomnotho zasezulwini njenge-ASTM D2513, ISO4437, ne-EN1555. Izinto ziyagcinwa ngokulingana nezindlela zomnotho wemaketi yasezulwini, noma yikuphi umkhakha wamandla, nokuthi kuyasebenza ngokulingana nezinkinga zokuphakama nokuthi kuyasebenza ngokulingana nezinkinga zomsebenzi, futhi kuyasebenza kumaketi yaseYurophu, e-Asia, neNtshonalanga yaseMeryka. Izipeyipi zisebenzisa ukugxila ngokuphakama kokushaya, okunika ubuhle obuhle bokugxila, ukuthabatha kwezinkinga zokuphakama kwezinkinga, nokuthi kuyasebenza ngokulingana nezinkinga zokuphakama kwezinkinga, futhi kuyasebenza kumakhelwane amandla esihlangu emadolobheni, kumasebenzi okugcina amandla esihlangu ngaphansi kwemvelo, nokusebenza kumasebenzi okungafanisiwe ngokuphakama kwezinkinga. Kuyasebenza ngokulingana nezinkinga zokuphakama kwezinkinga zokusebenza kumasebenzi amandla esihlangu asezingeni zasezulwini.
Kungani kusebenziswa izilayini zika-HDPE ukuthumela igasi elingelwe?
1. Ukusebenzisa ukugqibela ngokugqibela (ukugqibela ngokuchitha okunye nokugqibela ngokugqibela kwemithambo) kubhekise kahle ukuthi imithambo yezindawo zokugqibela nezinhlobo zayo iyafanana nomthwalo wendawo yomkhumbi , fakazela ukuthi indawo yokugqibela nezilayini ziyahlukahluka.
2. Iyathinteka ngokuphatha kokuvula kwezinye izinkimika : I-polyethylene yindlela engenakho yezinkimika futhi, ngaphandle kwezinye izinkimika ezingaphezulu kakhulu, iyathinteka ngokuphatha kokuvula kwezinye izinkimika. Ayikho ukuthinteka ngokuphatha kokuvula kwezinkimika kanye noma kufanele kwenziwe indawo yokuthinteka.
3. Ukuzimela Okwesibonelo Nokufanelwa Okwesibonelo . Ukuthinteka kwakho kuyadlula 500% kanye noma kufanele kwenziwe indawo yokuthinteka. isimo esifushane sikhuluma ngokuthinteka kwezindawo zokuthinteka , kuyadinga amaqhina amancane , kuyenza ukuthi isebenzise kwi-trenchless installation . Amaphakamelo: Amathuba okufana nokuthi amasiko ayalwa ayikwazi ukuphatha ukuguqula kwemhlaba ngamajoint angaphezulu , akwanele kuzo izibhambo zokugqogqola ngendlela engekho emagumbini (HDD) : izibhambo zokugcina igasi yasezwe , ukuthumela igasi yasezwe , izibhambo zegasi zempahla.
4. Ukugqoka kakhulu kwezibhambo kungabangela izimpilo ezingavumelekile, noma ukugqoka kuyaphuma ngemispeed yamahundred emitri ngosekondi, ngokushesha kubangela ukugqoka kwezibhambo zemithili engaphezulu noma kwezinkulungwane. Izibhambo ze-PE, ngaphandle kwalokho , kunezimisela kahle kuzo zonke izindlela zokuphambana komkhono ngokushesha.
- Ngokuba kunezindawo eziningi zokusebenza futhi izindlela zokuhlinzeka zizilinganiswe ngaphansi kweminyaka engu-50 (kubhekana nezimo nezinhlobo) noma yiziphi izindlela zokuhlinzeka, kuyabeka ukuthi izindlela zokuhlinzeka zingaphezulu. Ukuthenga kwanasekunqubeni kukwesinye kuphela kwezinto ezingafanele ukubhekwa; ukuthenga kwezinyanga zonke kuyisisekelo esibalulekile.
- Ukuthumela okuphansi kwezindawo zokusebenza ngokusebenzisa i-HDPE (high-density polyethylene) yezinhlanga zokugcina amanzi; ukuncamisa kwezindlela zokufaka, izinto ezingafakwa emvelweni futhi ukuncamisa kwezindlela zokuhlinzeka.

AMAPHUZA: Izinhlanga zokugcina amanzi ze-HDPE yokuthumela amanzi angcono n
1. Iziphakamiso zokusebenza kwe-HDPE zokugcina igasi ziyakufanele zifanele ngezindlela zokusebenza ziphi?
Iziphakamiso zokusebenza kwe-HDPE zokugcina igasi kufanele zifanele nezindlela zokusebenza eziqinisekisiwe, njenge-ISO 4437, EN 1555, ne-ASTM D2513, noma nezindlela zokusebenza zokugcina igasi ezindaweni zabo. Lezi zindlela zokusebenza ziqinisekisa ubukhulu bezinto, ubukhulu bekuphambuka kwamandla, nobuhlebhu beziphakamiso kumsebenzi wokugcina igasi lengculazi.
2. Kungasebenziswanga iziphakamiso zokusebenza kwe-HDPE zokugcina igasi kwezikhala zokugcina igasi ngaphansi kwelwandle?
Yebo, iziphakamiso zokusebenza kwe-HDPE zokugcina igasi zisebenziswa ngokubanzi kwezikhala zokugcina igasi ngaphansi kwelwandle. Ubukhulu bakho bokuthintana, ubukhulu bakuphatha ukungafani, nobukhulu bakuthintana nokuguqula kwezinkundla zibonisa ukuthi zingasebenziswane kumithambo yezinhlangano, yezindawo ezingaphansi kwelwandle, neyemithambo yezindawo zokusebenza yokugcina igasi.
3. Kuzoba kuphi ukuchaza phakathi kweziphakamiso ze-PE80 ne-PE100 zokugcina igasi?
Kunye neziphakamiso ze-PE80, iziphakamiso ze-PE100 zokugcina igasi zinamandla amaningi kanye nokuphambuka kwamandla amaningi, okuvumela ukuthi iziphakamiso zibe nzima futhi ukuthi ubukhulu bezinto besebenziswe ngokuphelele. Iziphakamiso ze-PE100 zihlalwa kusukela kwezikhala zokugcina igasi zengculazi ezinamandla amaningi.
4. I-SDR rating iphi esivumelana nezindlela zokusebenza zezilayini zama-gas ezinkulu ze-HDPE?
I-SDR rating esivumelana kuyisiphakade se-pressure sokusebenza, ububanzi bezilayini, nokuthandekile kwezindlela zokusebenza. Izinketho eziphakade ziyi-SDR11 ne-SDR17, noma ukukhetha okuphelele kuyisiphakade se-pressure nezindlela zokusebenza zezilayini ezivumelanayo.
5. Iziphi izinto ezidingeka ukuzibona xa kufundiswa izilayini zama-gas ze-HDPE kuma-manufacturers?
Xa kusukela ukukhetha umthengisi we-HDPE gas pipeline, kufanele kubhekwe izinto ezifanayo ne-ububi bokwakhiwa, iziqinisekiso, ubukhulu bekuproducwa, izindlela zokuzilinganisa, izinsiza zokuhlanganisa ngokulinganayo, nokwazi kwezilayini zama-gas ezinkulu.
