Ipayipi le-PPR Eliphezulu Eliluhlaza Okwesibhakabhaka Eligcwele Le-HAVC Namanzi Abandayo
Imikhumbi kanye nezakhiwo zasogwini lolwandle uhlelo olufanele lwe-HVAC lubaluleke kakhulu esimweni sezulu esilawulwa kahle kanye nenduduzo yabagibeli kanye nabasebenzi.
Uhlelo ludinga ukuhlelwa futhi lwakhiwe ngendlela engcono kakhulu, kucatshangelwa uhlobo lwemikhumbi, impilo, ukuphepha, kanye nezici zemvelo ukuqinisekisa ukusebenza okuphephile nokusebenza kahle. Uma kwenzeka amayunithi amanzi abandayo kanye nama-chiller okumunca, ngokuvamile kuba nenethiwekhi yamapayipi ebanga elide exhumanisa isitshalo sokupholisa namayunithi okuphatha umoya emakhishini/ezindaweni zokusebenza noma namayunithi okupholisa imishini kagesi.
Indlela evamile yokuthutha amandla amanzi noma ingxube yamanzi/i-glycole, ikakhulukazi ukugwema izinhlelo ezinkulu zamapayipi eziqandisi. Kwezinye izinhlelo zokusebenza, amanzi olwandle angasetshenziswa njengendawo yokupholisa yamahhala. Kulezi zinhlelo zokusebenza ezinzima kubaluleke kakhulu ukukhetha uhlelo olufanele lwamapayipi.
Ipayipi eliluhlaza okwesibhakabhaka le-aquatherm, elitholakala ngobukhulu obusukela ku-20 kuya ku-315mm, liyisinqumo esingcono kakhulu ngenxa yokumelana kwamakhemikhali okuvumela impilo yesevisi efinyelela eminyakeni eyi-100 ezimweni zokusebenza eziqhubekayo. Uma kuqhathaniswa namapayipi ensimbi noma e-GFR, amapayipi e-polypropylene anesisindo esincane esingasiza ekunciphiseni izindleko zikaphethiloli.

UKUHLOLWA KWENGCINDEZELO
Ngokusho kweMithetho Yobuchwepheshe Yokufakwa Kwamanzi Okuphathekayo DIN1988, ingcindezi yokuhlola kufanele ibe izikhathi eziyi-1.5 zengcindezi yokusebenza kwezinhlelo zamapayipi.
Lapho kwenziwa ukuhlolwa kokucindezela, izakhiwo zezinto zamapayipi e-PP-R ziholela ekwandeni kwepayipi, okuthonya umphumela wokuhlolwa. Ithonya elengeziwe kumphumela wokuhlolwa lingabangelwa yi-coefficient yokwanda kokushisa kwamapayipi e-PP-R. Amazinga okushisa ahlukene epayipi kanye ne-test medium aholela ekwehlukeni kwebha engu-0.5 kuya ku-1. Ngakho-ke, i-lemperature ephezulu kakhulu ye-test medium kufanele iqinisekiswe ekuhlolweni kokucindezela kwe-hydraulic kokufakwa kwamapayipi e-PP-R.
Ukuhlolwa kwengcindezi ye-hydraulic kudinga ukuhlolwa kokuqala, okuyinhloko kanye nokugcina. Ekuhlolweni kokuqala, ingcindezi yokuhlola ephindwe ka-1.5 yengcindezi yokusebenza ephezulu kakhulu okungenzeka ukuthi iyasebenza kufanele ikhiqizwe. Lo mfutho wokuhlola kufanele umiswe kabusha kabili zingakapheli imizuzu engama-30 zingakapheli imizuzu eyi-10. Ngemva kwesikhathi sokuhlola seminye imizuzu engama-30, ingcindezi yokuhlola akumele yehle ngaphezu kwe-0.6 bar futhi akukho ukuvuza okuzovela.
Ukuhlolwa kokuqala kufanele kulandelwe ngqo ukuhlolwa okuyinhloko. Isikhathi sokuhlolwa singamahora ama-2. Uma kwenziwa kanjalo, ingcindezi yokuhlola ingase ingabi ngaphezu kwebha engu-0.2. Lapho ukuhlolwa kokuqala kanye nokuyinhloko sekuqediwe, kulandela ukuhlolwa kokugcina, okumele kwenziwe ngengcindezi yokuhlola yebha engu-10 ehlukile kanye nebha engu-1 ngesigqi okungenani imizuzu emi-5. Phakathi kokuhlolwa ngakunye, ingcindezi kufanele ikhishwe. Akukho ukuvuza okungavela nganoma yisiphi isikhathi.
Isicelo
I-CHUANGRONG iyinkampani ehlanganisiwe yezimboni kanye nezohwebo, eyasungulwa ngo-2005 eyayigxile ekukhiqizweni kweAmapayipi e-HDPE, Izinto Zokufaka Namavalvu, Amapayipi e-PPR, Izinto Zokufaka Namavalvu, Izinto Zokucindezela ze-PP Namavalvu, kanye nokuthengiswa kwemishini Yokushisela Amapayipi Epulasitiki, Amathuluzi Amapayipi, I-Clamp Yokulungisa Amapayipinjalo njalo.
I-CHUANGRONG inethimba labasebenzi elihle kakhulu elinolwazi olucebile. Inhloko yayo uBuqotho, Ubuchwepheshe kanye Nokusebenza Kahle. Isungule ubudlelwano bebhizinisi namazwe angaphezu kuka-80 nezindawo embonini ehlobene. Njenge-United States, iChile, iGuyana, i-United Arab Emirates, iSaudi Arabia, i-Indonesia, iMalaysia, iBangladesh, iMongolia, iRussia, i-Afrika njalo njalo.
Siyakwamukela ukuxhumana nathi ukuze uthole imininingwane yemikhiqizo kanye nensizakalo yobungcweti.
