Isampula yamahhala ye-China ASTM A53/BS1387 Ipayipi Lensimbi Elifakwe Intambo Elihlanganisiwe nelihlanganisiwe
Uhlolojikelele
Ilungu ngalinye elivela eqenjini lethu lemali engenayo yokusebenza enkulu lizazisa izimfuneko zamakhasimende kanye nokuxhumana kwenhlangano kwe-ASTM A53/BS1387 Ipayipi Lensimbi Elifakwe Ngamanzi Elishisayo Elishisayo. Sithemba ukuthi singaba umphakeli wakho onokwethenjelwa e-China. Sibheke phambili ukubambisana kwakho .Ngokuhlangenwe nakho kweminyaka engaphezu kwengu-9 kanye neqembu lochwepheshe, sithumele imikhiqizo yethu emazweni amaningi nasezifundeni emhlabeni jikelele. Samukela amakhasimende, izinhlangano zamabhizinisi nabangane abavela kuzo zonke izingxenye zomhlaba ukuze baxhumane nathi futhi bafune ukubambisana ukuze bathole izinzuzo ezifanayo.
I-hot-dip galvanizing inezinzuzo zokugqoka okufanayo, ukunamathela okuqinile nokuphila isikhathi eside. Ukusabela okuyinkimbinkimbi ngokomzimba namakhemikhali kwenzeka phakathi kwe-matrix yepayipi lensimbi nesisombululo sokucwenga esincibilikisiwe ukuze kwakhe ungqimba lwengxubevange ye-zinc-iron olungagqwali olunesakhiwo esihlangene. Isendlalelo se-alloy sihlanganiswe nesendlalelo se-zinc ehlanzekile kanye ne-matrix yepayipi yensimbi. Ngakho-ke, ukumelana kwayo nokugqwala kunamandla.
Kumele kuqashelwe ukuthi ngeminyaka yawo-1960 nawo-1970, amazwe athuthukile emhlabeni aqala ukuthuthukisa izinhlobo ezintsha zamapayipi futhi kancane kancane avala amapayipi anamathani. Ongqongqoshe namakhomishini amane okuhlanganisa nowezokwakha eChina nawo akhiphe umqulu ocacisa ukuthi amapayipi kathayela avaliwe kusukela ngo-2000 kuya phambili. Amapayipi anothayela awavamile ukusetshenziselwa amapayipi amanzi abandayo emiphakathini esanda kwakhiwa, kanti amapayipi anathayela asetshenziselwa amapayipi amanzi ashisayo kweminye imiphakathi.
Isicelo
Isetshenziselwa Ngokuyinhloko izingxenye zamandla nengcindezi, futhi ngenjongo evamile yamapayipi omusi, amanzi, igesi nomoya.
