PND: emagama izifinyezo. HDPE ipayipi

Esanda kutholakala ngasibuyisela kwayo material ezifana HDPE. Incazelo izifinyezo simiswe ngalendlela lelandzelako: ongaphakeme-ukuminyana polyethylene. Pipe ekhiqizwa therefrom njengoba lisetshenziswe kulesi ubuchwepheshe nesikulufu extrusion uhlobo okuqhubekayo. Indlela ivumela ukuthola imikhiqizo ezithinta azifani.

Izici HDPE-amapayipi

Inqawe kuthiwa Lifanele ukuthuthwa eziwuketshezi bese kuthi amagesi. Zisetshenziswa ngenkuthalo, uma kunesidingo, ukuvikela izintambo wabeka ngaphansi emhlabeni kwezakhi. Lokhu ukusetshenziswa yingoba IPA has rigidity namandla. Ngaphezu kwalokho, low-ingcindezi polyethylene amelana zangaphandle, kuhlanganise weathering, kubika iKickOff.com ngoLwesithathu. Indaba engasetshenziswa uma ebeka zangaphakathi nezangaphandle amapayipi izinhlelo.

Enye inzuzo yokuhamba kwesikebhe HDPE amapayipi (okulotshiweyo - High Wugqinsi polyethylene) izindleko ongaphakeme, okuyinto ngenxa yokuthi izinto zokusetshenziswa yesibili kusetshenziswa ekukhiqizeni. Ngakho, ukukhiqizwa kwe pipe ezichazwe isiza ukugcina imvelo njengoba imithombo yesibili awangeni imvelo njengoba udoti. Inqawe eyenziwe HDPE kungaba ubukhulu ehlukene kakhulu, okuvumela ukusetshenziswa yabo emikhakheni ehlukahlukene.

HDPE amapayipi pluses

HDPE ipayipi (okulotshiweyo isivele zaziwe umfundi) kunezinzuzo eziningi. Ngaphezu okungenhla, singakwazi ukuhlukanisa ngisho isikhathi sasivumela eside wokusebenza. Ukuze uqhathanise, amaphayiphi ezenziwe ngensimbi, zisetshenziswe 3 noma ezincane ngisho izikhathi 5 kuqhathaniswa IPA-imikhiqizo. Material ngokuphelele asesabi kumakhemikhali okungenakugwenywa futhi ukugqwala izinqubo. Lapho uxhumana imvelo nolaka ipayipi isikhathi eside angeke ulahlekelwe amakhono abo. Banezinhliziyo ongaphakeme ezishisayo conductivity ezingeni, yingakho phezu aliveli condensate.

Umkhiqizo HDPE (emagama izifinyezo, by the way, esiza umthengi ngesikhathi ukuthengwa kwezimpahla) ayidingi Ukuvikelwa cathodic laying nezintambo zikagesi. Izindonga amapayipi ikhululekile ngokwanele, yingakho akukho ingozi ukuthi umkhiqizo wavele ngesikhathi umnkantsha ngaphakathi ketshezi. Ezokuthutha, ethula bese beka kula mapayipi Kuyinto elula kakhulu, ngoba isisindo aphansi kakhulu.

Ukwahlukanisa HDPE-amapayipi

Uma ufuna ukuthenga eliphezulu HDPE-ipayipi, kufanele ukhethe lowo senziwa ngokuhambisana GOST 18 599-83. Phakathi mikhiqizo kungenzeka okuthiwa amapayipi esindayo, okuyinto ezikhonjiswe esibhalwe ukuthi "T". Lezi zihloko zingase zibe Ngokwesilinganiso, ngesisindo, kanye ukukhanya yesibili, esimweni esinjalo, umkhiqizi kufanele likhethe mshini zabo "C" futhi "SL", ngokulandelana. Uma tube senziwa oda, khona-ke uyobona ke ubekwa uphawu "Nest."

Izinhlobo HDPE-imikhiqizo

HDPE ipayipi (okulotshiweyo - ongaphakeme ukuminyana polyethylene) zingaba enezindonga ngothayela noma bushelelezi. amapayipi kwakamuva zobuchwepheshe babe isendlalelo esisodwa, futhi angathengwa coil. I samuntu okunye has a ezimbili ungqimba ipayipi isakhiwo. On ebusweni elingaphandle imiphetho ukubonakala, okuyinto zenzelwe ukuvikela mechanical umthelela ungqimba kwangaphakathi. imikhiqizo enjalo avame ukusetshenziswa lapho kokufaka izinhlelo eziqhutshwa ngomshoshaphansi.

sphere kwesicelo

Kabanzi ukukhishwa imithombo kwezobuchwepheshe, futhi uma kudingekile ukwenza intambo inhlangano kanye wire HDPE ipayipi. Kulungiswa lesi silinganiso kusisiza ukuba siqonde ukuthi ngesisekelo komkhiqizo ephezulu amandla plastic. Le mikhiqizo kabanzi emsebenzini adonsela phansi amapayipi nezinye izinhlelo zangaphandle. Ziyakwazi lalivamile ezimweni izindawo nezasemalokishini ekwakhiweni emizini yabazalwane. Ziyakwazi ethandwa phakathi abathengi, abahamba ukuhlela ukufakwa ecashile ugesi, okubhekisele Kulezo zimo lapho uhlelo kuthiwa ufihle ngemuva amaphepha okwakhiwa ngalo la mabhodi, kungaba kokubili izindonga kakhonkolo kanye phansi ephakanyiswe.

HDPE-imikhiqizo - ukuvikelwa ikhebuli kagesi

Ziningi ukuchaza amagugu ethile, futhi kuhluke ngokuphelele ekufundeni we IPA. Medicine, isibonelo, ukunika incazelo yakhe - esibhedlela sengqondo, engesiyo kudidaniswe poelietilenom ingcindezi ongaphakeme.

Inqawe eyenziwe Isidlulisilwazi polyethylene elisetshenziswa Ngohlelo futhi izintambo zikagesi. Tube ivikela kahle intambo ekulimaleni lokukhanda. Uma ukwahlukanisa ikhebula lilimele, tube uyobavikela umuntu abanjwe ugesi. Lapho kuphakama isimo esiphuthumayo echazwe kungenzeka short circuit, elibangela umlilo, kuleso simo ipayipi kuzovimbela ukusabalala umlilo.

izici lobuchwepheshe

Abaningi banesithakazelo ngaphambi kokuthenga okulotshiweyo HDPE-f. Ochwepheshe bayazazi ukuthi lokhu kubonisa ukuthi ngaphambi ipayipi wena eyenziwe ongaphakeme ukuminyana polyethylene ngenhloso ububanzi ethize zangaphandle, okuyinto okhonjiswe incwadi "f". Ngaphambi kokuthenga kubalulekile ukuba banake hhayi kuphela impahla, kodwa futhi izici okufanele zifinyelelwe umkhiqizo. Ngakho, uma ufuna ukuthenga ngamapayipi bushelelezi, ebusweni akumelwe zinamaphutha ngesimo uyaxebuka, igawula, amashashazi ngokuhlaziya. Wena akufanele silithathe kancane ebusweni engaphakathi ipayipi. Lokhu kumayelana imikhiqizo lobuchwepheshe kanye amapayipi. Ngesisekelo yasekhaya akufanele kube hillocks nezigodi, njengoba ungase ube isithiyo uma Ukuchusha ikhebula.

IPA-tube, emagama (ubukhulu 110) lapho kwethulwa ngenhla, kufanele itholakale ubude iqonde. Mayelana amashubhu, ububanzi okuyinto ingeqi 90 mm, bona nokuqalisa coil. Uma udinga ukuthenga amapayipi e ubude iqonde, ubude bazo kungaba 5-12 m. Kodwa ukuphambuka kuvunyelwe kusukela kule obuphelele, okuyinto akumele leqe 2%.

Floor ubuchwepheshe

IPA-f (okulotshiweyo izifinyezo - ongaphakeme ukuminyana polyethylene) kungenziwa wabeka phezu ububanzi lokushisa ububanzi. Nokho, embundwini aphansi akufanele kube ngaphansana ^-30 ° C. Nokho, abanye imingcele zisekhona, bayilalela yokuthi asikwazi adalule evele sangaphakathi amapayipi uketshezi nezingahlobene nendaba, uwoyela, ukungcola kanye nezinye izinto. Ngemva kakhulu ebeka le akumele bavunyelwe, lokho kuthathwa izinyathelo ezifanele ukuze seal futhi uphawu izakhi ezindaweni esibonakalayo.

Ukuze ukuletha tube kusuka ezenzeka condensate, kufanele ukukhwezwa nge eyehlelayo ezithile, iqondiswe ekufezeni ezathatha isikhathi eside amabhokisi asetshenziswa ukuqoqa umswakama.

Uma kukhona isidingo ukubeka ipayipi ngasesinqeni se isakhiwo ke lokhu kufanele kwenziwe ngokubeka izakhi ngokuqondile. Emva imikhiqizo zigcwele isixazululo. Uma umkhiqizo akusho walala nendawo, umthwalo kubo izokwabiwa Ukuboshelwa, engabangela umonakalo. Lapho ebeka amapayipi ngesikhathi ukujula okuyinto mkhulu kunezinhliziyo 2 m, kubalulekile ukuba isivikelo ezengeziwe owakhiwa concreting siteshi. Hlomisani ungqimba ukhonkolo akufanele kwenziwe emincane noma emikhulu kunalokhu 80-100 mm.

HDPE-imikhiqizo ye eziphansi, kodwa babe high izici, kungenzeka ukuzisebenzisa hhayi kuphela laying indle namanzi ompompi, kodwa futhi nokuvikela ikhebula, ukukhwezwa ngomshoshaphansi. Imikhiqizo kukhona jikelele, njengoba asetshenziswe kule izinhlelo ukuvuselelwa, isakhiwo zangaphakathi nezangaphandle, esangenza ukuba bathole ukusatshalaliswa kwandile, kuhlanganisa ukufakwa isiphepho amapayipi.
