Ipayipi elishisayo lokucwilisa
Incazelo emfushane:
Ipayipi elishisayo le-dip lashukumisa, ukuze kuthuthukiswe ukumelana nokugqwala kwepayipi lensimbi, ipayipi lensimbi elijwayelekile liyakhanyiswa.Amapayipi ensimbi enziwe ngensimbi ahlukaniswe abe i-hot-dip galvanizing kanye ne-electro galvanizing.I-hot-dip galvanizing layer iwugqinsi, izindleko ze-electro galvanizing ziphansi, futhi ingaphezulu alibushelelezi kakhulu.
inhloso
Amapayipi ensimbi asetshenziselwa igesi, i-greenhouse kanye nokufudumeza nawo angamapayipi.Njengamapayipi amanzi, amapayipi amapayipi akhiqiza inani elikhulu lokugqwala nesikali emapayipini.Amanzi aphuzi awagcini nje ngokungcolisa i-sanitary ware, kodwa futhi ahlanganiswe nama-bacteria azalela odongeni lwangaphakathi olungabushelezi.Ukugqwala kubangela okuqukethwe kwezinsimbi ezisindayo emanzini ukuba kuphakame kakhulu, okubeka engcupheni impilo yomuntu.Ngeminyaka yawo-1960 kanye nawo-1970, amazwe athuthukile emhlabeni aqala ukwakha amapayipi amasha, futhi amapayipi anamathani avalwa ngokulandelana.UMnyango Wezokwakha eShayina kanye nezinye izinkonzo ezine namakhomishini nawo akubeke kwacaca ukuthi amapayipi awuthayela avaliwe kusukela ngo-2000. Amapayipi anothayela awavamisile ukusetshenziselwa amapayipi amanzi abandayo emiphakathini emisha, namapayipi anguthayela asetshenziselwa amapayipi amanzi ashisayo kweminye imiphakathi.
