Amapayipi Ensimbi Akhandiwe Asezingeni Eliphezulu Emisebenzi Yokwakha
Ipayipi elinothayela elidiphu elishisayo elokwenza insimbi encibilikisiwe isabelane ne-iron matrix ukuze ikhiqize ungqimba lwengxubevange, ukuze i-matrix ne-coating kuhlanganiswe.I-hot-dip galvanizing iwukuba ugqume ipayipi lensimbi kuqala.Ukuze kukhishwe i-iron oxide ebusweni bepayipi lensimbi, ngemva kokuchotshozwa, ihlanzwa ethangini nge-ammonium chloride noma i-zinc chloride isixazululo samanzi noma isixazululo esinamanzi esixubile se-ammonium chloride ne-zinc chloride, bese sithunyelwa ku-In. ithangi lokucwilisa elishisayo.I-hot-dip galvanizing inezinzuzo zokugqoka okufanayo, ukunamathela okuqinile nokuphila isikhathi eside.I-matrix yepayipi lensimbi elidiphu elishisayo ibhekana nokusabela okuyinkimbinkimbi ngokomzimba namakhemikhali nesixazululo sokucwenga esincibilikisiwe ukuze kwakhe ungqimba lwengxubevange yensimbi ye-zinc-iron enesakhiwo esihlangene.Isendlalelo se-alloy sihlanganiswe nesendlalelo se-zinc ehlanzekile kanye ne-matrix yepayipi yensimbi, ngakho ukumelana kwayo nokugqwala kunamandla.
Ipayipi elibandayo elinothayela liyi-electro-galvanized, futhi inani lokufaka uthayela lincane kakhulu, lingama-10-50g/m2 kuphela, futhi ukumelana nokugqwala kwalo kubi kakhulu kunalelo lepayipi elinothayela elishisayo.Iningi labakhiqizi bamapayipi abavamile abalisebenzisi i-electro-galvanization (i-cold plating) ukuze baqinisekise ikhwalithi.Yilawo mabhizinisi amancane kuphela anemishini emincane nephelelwe yisikhathi asebenzisa i-electro-galvanization, futhi vele amanani awo ashibhe uma kuqhathaniswa.UMnyango Wezokwakha umemezele ngokusemthethweni ukuthi kufanele kuqedwe amapayipi anothayela ababandayo anobuchwepheshe obubuyela emuva, namapayipi anamathayela abandayo awavunyelwe ukuthi asetshenziswe njengamapayipi amanzi negesi.Ungqimba olunathayela lwepayipi lensimbi elibandayo liwungqimba olufakwe i-electroplated, futhi ungqimba lwezinc luhlukaniswa ne-matrix yepayipi lensimbi.Isendlalelo se-zinc sincane, futhi ungqimba lwe-zinc lumane lunamathele ku-substrate yepayipi yensimbi futhi kulula ukuwa.Ngakho-ke, ukumelana nokugqwala kwayo kubi.Ezindlini ezisanda kwakhiwa, akuvunyelwe ukusebenzisa amapayipi ensimbi abandayo njengamapayipi okuhambisa amanzi.
Amazinga kazwelonke kanye namazinga osayizi wamapayipi anamathani
I-GB/T3091-2015 Ipayipi lensimbi elishiselwe ukuthutha uketshezi olunengcindezi ephansi
GB/T13793-2016 Straight Seam Electric Welded Steel Pipe
I-GB/T21835-2008 usayizi wepayipi lensimbi elishiselwe kanye nesisindo sobude beyunithi
Amapayipi ensimbi ashisayo asetshenziswa kabanzi ekwakheni, imishini, izimayini zamalahle, amakhemikhali, amandla kagesi, izimoto zikaloliwe, imboni yezimoto, imigwaqo emikhulu, amabhuloho, iziqukathi, izikhungo zemidlalo, imishini yezolimo, imishini kaphethiloli, imishini yokuhlola, ukwakhiwa kwe-greenhouse nokunye. izimboni zokukhiqiza.
Amapayipi ensimbi ashiselwe amapayipi ensimbi ane-hot-dip galvanized noma i-electro-galvanized layer phezu komhlaba.I-galvanizing ingakhuphula ukumelana nokugqwala kwepayipi lensimbi futhi yandise impilo yesevisi.Ipayipi elinothayela linokusetshenziswa okubanzi.Ngaphezu kwamapayipi kalayini okudlulisa amanzi, igesi, uwoyela kanye nolunye uketshezi olujwayelekile olunomfutho ophansi, ibuye isetshenziswe njengamapayipi emithombo kawoyela namapayipi kawoyela embonini kawoyela, ikakhulukazi izindawo zikawoyela ezingasogwini, kanye nezifudumezi zikawoyela kanye nokujiya lapho kuphekwa amakhemikhali. imishini.Amapayipi ama-coolers, izishintshi zikawoyela ohlanzwa ngamalahle, izinqwaba zamapayipi zamabhuloho adonsa kanzima, namapayipi ozimele bokusekela emigodini yezimayini, njll.
