Ipayipi Lensimbi Eshisayo Yase-China/Ipayipi Lensimbi Elishiselwe, ASTM A53 API 5L
Uhlolojikelele
Kungaba ukuziphendulela kwethu ukwanelisa okuncamelayo futhi sikunikeze ngokufanelekile. Ukwaneliseka kwakho kuwumvuzo wethu omkhulu kakhulu. Sibheke phambili ekuhambeleni kwakho ukuze sikhule ngokubambisana. Ngenxa yemizamo yethu, izimpahla zethu zizuze ukwethenjwa abathengi futhi zithengiswa kakhulu ngokulinganayo lapha naphesheya. Imboni yethu iphikelela kumgomo othi "Ikhwalithi Yokuqala, Ukuthuthukiswa Okusimeme", futhi ithatha "Ibhizinisi Elithembekile, Izinzuzo Ezihlangene" njengomgomo wethu ongathuthukiswa. Wonke amalungu abonga ngobuqotho ngakho konke ukwesekwa kwamakhasimende amadala namasha. Sizoqhubeka nokusebenza kanzima futhi sikunikeze imikhiqizo nesevisi yekhwalithi ephezulu kakhulu.
Mayelana ne-carbon steel eshiselwe nepayipi elingenamthungo, ukuze kukhuliswe ikhono lokumelana nokugqwala, kuzoba khona uhlobo oluthile lokwelapha lwamapayipi. Enye yezinto ezisetshenziswa kakhulu yijazi le-zinc (galvanize). Kunezinhlobo ezimbili zendlela yokwenza i-galvanizing: i-glavanizing ebandayo (i-electrogalvanizing) kanye ne-galvanizing eshisayo. Ngenxa yokuthi inkinga yemvelo, ukucwebezelisa okubandayo kunqunyelwe eShayina, futhi ukugalela amanzi ashisayo nakho akukwazi ukusetshenziswa njengepayipi lokuhambisa amanzi, kodwa kusetshenziswe kabanzi ekucimeni umlilo, ugesi kanye nothelawayeka.
I-Cold galvanizing i-electrogalvanizing, ngenxa yomkhawulo wesu, ijazi le-zinc aliningi, ikakhulukazi ku-10-50g/m2, ngakho-ke, ikhono layo lokumelana nokugqwala lingaphansi kokushisa okushisayo. UMnyango Wezokwakha usuqede ngokusemthethweni ukuqedwa kwamapayipi abandayo anothayela ngobuchwepheshe obubuyela emuva, futhi akuvumelekile ukusebenzisa amapayipi abandayo amapayipi amanzi negesi. Isendlalelo esinezinsimbi zepayipi lensimbi elicwebezelayo elibandayo liyisingqimba se-electroplated, futhi isendlalelo se-zinc kanye ne-substrate yepayipi lensimbi zendlalwe ngokuzimela. Ungqimba lwe-zinc luncane kakhulu, futhi ungqimba lwe-zinc lumane lunamathele ku-substrate yepayipi yensimbi futhi kulula ukuwa. Ngakho-ke, ukumelana nokugqwala kwayo kubi.
Ungqimba lwe-alloy pipe yepayipi elishisayo lakhiwa ukusabela kwensimbi encibilikisiwe kanye ne-substrate yensimbi, ukuze i-substrate ne-plating layer kuhlanganiswe, futhi ungqimba lokucwenga akulula ukuwa. I-hot dip galvanizing inezinzuzo zokuhlanganisa iyunifomu, ukunamathela okuqinile nempilo ende yesevisi. I-substrate yepayipi lensimbi elidiphu elishisayo elishisayo kanye nesixazululo sokucwenga esincibilikisiwe sibhekana nokusabela okuyinkimbinkimbi ngokomzimba namakhemikhali ukuze kwakhe ungqimba lwengxubevange yensimbi ye-zinc-iron enesakhiwo esihlangene. Isendlalelo se-alloy sihlanganiswe nesendlalelo se-zinc ehlanzekile kanye ne-substrate yepayipi yensimbi, ngakho ukumelana kwayo nokugqwala kunamandla.
Isicelo
Isetshenziselwa Ngokuyinhloko izingxenye zamandla nengcindezi, futhi ngenjongo evamile yamapayipi omusi, amanzi, igesi nomoya.
