Imininingwane Yomkhiqizo

Omaka bomkhiqizo

Sisebenzisa uhlelo oluphelele lwesayensi lokuphatha ikhwalithi ephezulu, ikhwalithi ephezulu nokholo oluphakeme, sizuza idumela elihle futhi sahlala kulo mkhakha wePipe Yensimbi Engenasici Noma Ishubhu Yesibhoyili Sokucindezela Embonini, Siqotho futhi sivulekile. Sibheke phambili ekuvakasheni kwakho nokusungula ubudlelwano obuthembekile nobuhlala isikhathi eside.
Sisebenzisa uhlelo oluphelele lwesayensi lokuphatha ikhwalithi ephezulu, ikhwalithi ephezulu kanye nokholo oluphakeme, sithola idumela elihle futhi sathatha le mboniI-Boiler Seamless Steel Pipe, ipayipi lensimbi engenamthungo, Inkampani yethu idonsa imibono emisha, ukulawula ikhwalithi okuqinile, uhla olugcwele lokulandela umkhondo wesevisi, futhi inamathela ekwenzeni imikhiqizo yekhwalithi ephezulu. Ibhizinisi lethu lihlose “ukwethembeka nokwethembeka, intengo evumayo, ikhasimende kuqala”, ngakho sizuze ukwethenjwa iningi lamakhasimende! Uma unentshisekelo ngemikhiqizo namasevisi ethu, sicela ungangabazi ukusithinta!

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.
