Ipayipi eliyisipesheli elinothayela lokuphuma
Incazelo emfushane:
Ipayipi elikhangayo, elaziwa nangokuthi ipayipi lensimbi elinamandla, lihlukaniswe laba i-hot-dip galvanizing kanye ne-electro galvanizing.I-hot-dip galvanizing layer iwugqinsi futhi inezinzuzo zokunamathela okufanayo, ukunamathela okuqinile nempilo ende yesevisi.Izindleko ze-electro galvanizing ziphansi, indawo engaphezulu ayibushelelezi kakhulu, futhi ukumelana kwayo nokugqwala kubi kakhulu kunombhobho wamanzi oshisayo oshisayo.
Ipayipi elishisayo le-dip lensimbi
Ukusabela okuyinkimbinkimbi ngokomzimba namakhemikhali kwenzeka phakathi kwe-matrix yepayipi lensimbi nesisombululo sokucwenga esincibilikisiwe ukuze kwakhe ungqimba lwe-zinc ferroalloy olungagqwali olunesakhiwo esihlangene.Isendlalelo se-alloy sihlanganiswe nesendlalelo se-zinc ehlanzekile kanye ne-matrix yepayipi yensimbi.Ngakho-ke, inokumelana nokugqwala okuqinile.
Ngemva kwentuthuko kusukela ngawo-1960 kuya ko-1970, izinga lomkhiqizo wepayipi lensimbi elishisayo lithuthukisiwe libe ngcono kakhulu.Kusukela ngo-1981 kuya ku-1989, ibilokhu ibhekwa njengomkhiqizo osezingeni eliphezulu woMnyango Wezezinsimbi kanye nendondo yesiliva kazwelonke.Umphumela ukhuphuke iminyaka eminingi.Umphumela wawungaphezu kwamathani angu-400000 ngo-1993 kanye namathani angaphezu kuka-600000 ngo-1999. Ithunyelwa eNingizimu-mpumalanga ye-Asia, e-Afrika, e-United States, eJapane, eJalimane nakwamanye amazwe nasezifundeni.Amapayipi e-dip galvanized amapayipi asetshenziswa kakhulu njengamapayipi okuhambisa amanzi namapayipi egesi, anezici ezijwayelekile zokuthi + 12.5 ~ + 102 mm.Kusukela ngeminyaka yawo-1990s, ngenxa yokunaka kombuso ekuvikelweni kwemvelo kanye nokulawula okuqinile ngokwengeziwe emabhizinisini angcolisa kakhulu, “imfucumfucu emithathu” ekhiqizwa ukukhiqizwa kwamapayipi afaka amanzi ashisayo kunzima ukuyixazulula, okuhambisana nokuthuthuka ngokushesha kwe-stainless. amapayipi ensimbi ashiselwe, amapayipi e-PVC namapayipi ayinhlanganisela, kanye nokukhuthazwa kwezinto zokwakha amakhemikhali kanye nokuvinjelwa kokusetshenziswa kwamapayipi ensimbi, Ukwakhiwa kwepayipi elishiselwe elishisayo elishisayo kwakuvinjelwe kakhulu futhi kulinganiselwe, kanye nokuthuthukiswa kwamapayipi ashisayo. -dip galvanized welded pipe yayihamba kancane.
Ipayipi elibandayo lensimbi
I-zinc layer iyingqimba ye-electroplating, ehlukaniswa ne-matrix yepayipi lensimbi.Ungqimba lwe-zinc luncane, futhi ungqimba lwe-zinc lumane lunamathele ku-matrix yepayipi yensimbi, okulula ukuwa.Ngakho-ke, ukumelana nokugqwala kwayo kubi.Ezindlini ezintsha, akuvunyelwe ukusebenzisa amapayipi ensimbi abandayo njengamapayipi okuhambisa amanzi.
