I-Factory Seamless Steel Tube Pressure Boiler Pipe From Steel Mill
Ngokusekelwa ithimba le-IT elithuthukile nelichwepheshile, singanikeza ukusekelwa kwezobuchwepheshe ekuthengisweni kwangaphambilini nangemuva kosizo lokuthengisa lwe-Factory Seamless Steel Tube Pressure Boiler Pipe From Steel Mill, Sikwamukela ngokufudumele ukuthi udale ukubambisana nakanjani futhi ukhiqize amandla amahle ndawonye. Unathi.
Ngokusekelwa ithimba le-IT elithuthukile nelichwepheshile, singanikeza ukwesekwa kobuchwepheshe ekuthengisweni kwangaphambilini nosizo lwangemva kokuthengisa28 Inch Well Casing Carbon Engenamthungo Kanye Nepayipi Lamafutha Lihle, Ipayipi Lensimbi Elingenamthungo Lokucindezela Uwoyela Negesi Ezokuthutha, Amapayipi Ensimbi Angenamthungo Omapayipi Kawoyela Negesi, Ngenhloso “yokuncintisana ngekhwalithi enhle futhi sithuthuke ngobuhlakani” kanye nomgomo wesevisi “wokuthatha ukufunwa kwamakhasimende njengokuqondiswa”, sizohlinzeka ngobuqotho izixazululo ezifanelekayo kanye nenkonzo enhle kumakhasimende asekhaya nawamazwe ngamazwe.

Isidingo Sokuhlola
Ngokungeziwe ekuqinisekiseni ukwakheka kwamakhemikhali kanye nezakhiwo zemishini, ukuhlolwa kwe-hydrostatic kwenziwa ngakunye, futhi kwenziwa ukuhlolwa kwe-flaring ne-flattening. . Ngaphezu kwalokho, kunezidingo ezithile ze-microstructure, usayizi wokusanhlamvu, kanye nongqimba lwe-decarburization yepayipi yensimbi eqediwe.
