Indali eshisayo yase-China Amapayipi Ensimbi Angenamthungo Agoqelwe Angenamthungo Izinto Zokwakha Ezingenamthungo Pipe Carbon Steel
Uhlolojikelele
Sinalesi siqubulo engqondweni, sesibe phakathi kwabakhiqizi abasungula kakhulu ubuchwepheshe, ababiza imali eningi, nabancintisana nentengo Amapayipi Ensimbi Angenasici Ashisayo-Rolled, Siyakwamukela bonke abathengi abahle baxhumane nathi imininingwane yezisombululo nemibono!! Sigcina imizamo yesikhathi eside nokuzigxeka, okusisiza futhi sithuthuke njalo. Silwela ukuthuthukisa ukusebenza kahle kwamakhasimende ukuze songe izindleko kumakhasimende. Senza konke okusemandleni ethu ukuthuthukisa ikhwalithi yomkhiqizo. Ngeke siphile ngendlela eyingqophamlando yethuba lezikhathi.
Isicelo
Ipayipi lensimbi engenamthungo yokusebenza okuphezulu kokushisa kwe-ASTM A106, efanelekile ukushisa okuphezulu
Ibanga Eliyinhloko
Ibanga lensimbi yesakhiwo sekhabhoni yekhwalithi ephezulu: G.A,GR.B,GR.C

Isidingo Sokuhlola
Ngokungeziwe ekuqinisekiseni ukwakheka kwamakhemikhali kanye nezakhiwo zemishini, ukuhlolwa kwe-hydrostatic kwenziwa ngakunye, futhi kwenziwa ukuhlolwa kwe-flaring ne-flattening. .
