I-Astm Standard St37 Hollow Tube Square 2.5 Intshi Yeshubhu Yensimbi Eyisithako
Umbhobho oyisikwele ophekiwe, eyaziwa nangokuthi ipayipi lensimbi elinamandla, ihlukaniswe yaba idiphu elishisayo elinamakhati kanye nogesi kagesi amabili, idiphu elishisayo elanika ungqimba oluwugqinsi oluwugqinsi, elinoqweqwe lomfaniswano, ukunamathela okuqinile, impilo ende yenkonzo kanye nezinye izinzuzo. Izindleko ze-electrogalvanizing ziphansi, indawo engaphezulu ayibushelelezi kakhulu, futhi ukumelana kwayo nokugqwala kubi kakhulu kunamapayipi afaka amapayipi ashisayo.
Ipayipi elibandayo elinothayela: ipayipi elinothayela elibandayo liyizinsika zikagesi, inani likathayela lincane kakhulu, amagremu angu-10-50 kuphela ngemitha yesikwele, ukumelana nokugqwala kwalo kuhluke kakhulu kunepayipi elivuthayo elishisayo. Izitshalo ezivamile zokukhiqiza amapayipi amapayipi, ngekhwalithi, iningi alisebenzisi i-galvanizing kagesi (i-plating ebandayo). Yilawo mabhizinisi amancane kuphela anemishini engasebenzi asebenzisa i-galvanizing kagesi, yiqiniso, intengo ishibhile.
Ipayipi elinothayela elishisayo
Insimbi encibilikisiwe ihlangana ne-matrix yensimbi ukuze ikhiqize ungqimba lwengxubevange, ukuze i-matrix ne-coating kuhlanganiswe. I-Hot dip galvanizing iwukuba kuqala ukucosha ipayipi lensimbi, ukuze kukhishwe i-iron oxide ebusweni bepayipi lensimbi, ngemva kokukhetha, nge-ammonium chloride noma i-zinc chloride isixazululo samanzi noma i-ammonium chloride ne-zinc chloride exutshwe nethangi lesisombululo samanzi sokuhlanza, bese ungena ethangini lokucwenga elishisayo. I-hot dip galvanizing inezinzuzo zokuhlanganisa iyunifomu, ukunamathela okuqinile nempilo ende yesevisi. Iningi lezinqubo enyakatho zamukela inqubo yokugcwalisa i-zinc yepayipi lekhoyili eliqondile lebhande elinothayela.
Ipayipi elibandayo elinothayela
Ama-cold galvanized ama-galvanized kagesi, inani lama-galvanized lincane kakhulu, kuphela i-10-50g/m2, ukumelana kwayo nokugqwala kuhluke kakhulu kunepayipi elishisayo elinothayela. Abakhiqizi bamapayipi avamile, ukuze kuqinisekiswe ikhwalithi, iningi alisebenzisi i-galvanizing kagesi (i-plating ebandayo). Yilawo mabhizinisi amancane kuphela anemishini engasebenzi asebenzisa i-galvanizing kagesi, yiqiniso, amanani abo ashibhile. Esikhathini esizayo, amapayipi ama-galvanized abandayo awavunyelwe ukusetshenziswa njengamapayipi amanzi negesi.
Ipayipi lensimbi elicwebezelayo elishisayo
Ukusabela okuyinkimbinkimbi ngokomzimba namakhemikhali kwenzeka phakathi kwe-substrate yeshubhu lensimbi kanye nokugeza okuncibilikisiwe ukuze kwakhe ungqimba oluqinile lwengxubevange ye-zinc-iron ukumelana nokugqwala. Isendlalelo se-alloy sihlanganiswe nesendlalelo se-zinc ehlanzekile kanye ne-matrix yepayipi yensimbi. Ngakho-ke, ukumelana kwayo nokugqwala kunamandla.
Ngemuva kokuthuthukiswa kwepayipi elishisayo lensimbi eminyakeni yawo-1960 kuya ko-1970, izinga lomkhiqizo liye lathuthukiswa kakhulu, ngo-1981 kuya ku-1989 waklonyeliswa uMnyango weMetallurgical wemikhiqizo yekhwalithi ephezulu kanye nendondo yesiliva kazwelonke, ukukhiqizwa nakho kwanda iminyaka eminingi, ngo-1993 ukukhishwa okwengeziwe. amathani angaphezu kuka-400,000,1999 okukhipha amathani angaphezu kuka-600,000, futhi athunyelwa eNingizimu-mpumalanga ye-Asia, e-Afrika, e-United States, eJapane, emazweni nasezifundeni zaseJalimane. Amapayipi kathayela odiphu oshisayo asetshenziswa kakhulu njengamapayipi amanzi namapayipi egesi, futhi imininingwane evamile ingu-+12.5~+102 mm. Ngemuva kweminyaka yawo-1990, ngenxa yokunaka kombuso ekuvikelweni kwemvelo, ukulawulwa kwamabhizinisi angcoliswa kakhulu kuya ngokuya kuba nzima kakhulu, "imfucumfucu emithathu" ekhiqizwa ekukhiqizeni amapayipi ashisayo ashisayo kunzima ukuyixazulula, kuhlanganiswe ukuthuthukiswa okusheshayo kwensimbi engagqwali amapayipi ashiselwe, amapayipi e-PVC namapayipi ayinhlanganisela, kanye nombuso ukukhuthaza ukusetshenziswa kwezinto zokwakha zamakhemikhali, ukusetshenziswa kwamapayipi ensimbi aphekiwe kuvinjelwe, okwenza ukuthuthukiswa kwamapayipi ashiselwe ashiselwe ukucwilisa kuye kwaba kakhulu. I-Beam ethintekile futhi umkhawulo, idiphu elishisayo elishiselwe ipayipi elishiselwe kamuva lathuthuka kancane.
Ipayipi elibandayo lensimbi
Isendlalelo se-zinc yisimbozo sikagesi, futhi isendlalelo se-zinc sibekwe ngokuzimela nge-matrix yepayipi yensimbi. Ungqimba lwezinc luncane, futhi ungqimba lwezinc lumane lunamathiselwe ku-matrix yeshubhu lensimbi futhi kulula ukuwa. Ngakho-ke, ukumelana nokugqwala kwayo kubi. Ezakhiweni ezintsha zokuhlala, akuvunyelwe ukusebenzisa amapayipi ensimbi abandayo njengamapayipi okuhambisa amanzi.
Isicelo
Ngenxa yokuthi ipayipi eliyisikwele elinothayela lifakwe uthayela epayipini lesikwele, ngakho-ke uhla lwesicelo sepayipi lesikwele esinezinsimbi lunwetshwe kakhulu kunepayipi lesikwele. Isetshenziswa kakhulu odongeni lwamakhethini, ukwakhiwa, ukukhiqizwa kwemishini, amaphrojekthi wokwakha insimbi, ukwakhiwa kwemikhumbi, ubakaki wokukhiqiza amandla elanga, ubunjiniyela besakhiwo sensimbi, ubunjiniyela bamandla, imboni yamandla, ezolimo kanye nemishini yamakhemikhali, udonga lwamakhethini engilazi, i-chassis yezimoto, isikhumulo sezindiza nokunye. .
