Ukuze uthole izinto ezinenani eliphezulu noma ezibalulekile, cela ukuhlolwa kwe-PMI noma ukuhlolwa komuntu wesithathu.

Kungani ukuhlolwa kwe-PMI kubalulekile?

Ukuhlolwa kwe-PMI kusiza ukuqinisekisa izakhi zangempela ze-alloy zezinto zensimbi engagqwali. Kuwusizo kakhulu ekuboneni insimbi engagqwali engu-316L, 904L, insimbi engagqwali ephindwe kabili kanye nezinye izinhlobo ze-alloyed lapho i-Cr, i-Ni, i-Mo noma ezinye izakhi zithinta ngqo ukusebenza.

Ingabe i-MTC kufanele ihlolwe ngaphambi kokuthunyelwa?

Yebo. Abathengi kufanele babuyekeze i-MTC ngaphambi kokuthunyelwa noma nini lapho kungenzeka. Ukubuyekezwa kwasekuqaleni kusiza ukugwema ukulethwa okungalungile, izinto zokuhlola ezingekho, izinkomba ezijwayelekile ezingalungile noma izinkinga zemibhalo ngesikhathi sokususwa kwempahla kanye nokwamukelwa kwephrojekthi.

Isiphetho

Ukufunda ukufunda isitifiketi sokuhlola umshini wokugaya insimbi engagqwali kubalulekile kubathengi, onjiniyela, abahloli kanye namaqembu okuthenga amaphrojekthi. Ukubuyekezwa kochwepheshe be-MTC kufanele kufake ububanzi obujwayelekile, ukuhlonza ibanga, ukwakheka kwamakhemikhali, izakhiwo zemishini, ukulandelelwa kwenombolo yokushisa, amarekhodi okuhlola kanye nobuqiniso besitifiketi.

Ngezinto zensimbi engagqwali ezisetshenziswa emishinini yokucubungula amakhemikhali, izinhlelo ze-petrochemical, izakhiwo zasolwandle, imishini yokudla, imishini yokucindezela, izingxenye zesitimela kanye nokukhiqiza izimboni, i-MTC iyingxenye ebalulekile yokuqinisekisa ikhwalithi. Ngokuhlola isitifiketi ngokucophelela ngaphambi kokuthunyelwa, abathengi banganciphisa izingozi zezinto ezibonakalayo, bagweme ukubambezeleka kwephrojekthi futhi bathuthukise ukuthembeka kokunikezwa kwesikhathi eside.
