I-Duplex steel S31803 iityhubhu yenye yezona zinto zidumileyo kwaye zisetyenziswa ngokubanzi kwihlabathi. Badume ngamandla abo aphezulu, ukuqina kunye nokuxhathisa umhlwa. I-Duplex steel S31803 yintsimbi ye-duplex engenasici equkethe i-25% yechromium kunye ne-7% nickel. Inamandla aphezulu kumlinganiselo wobunzima kunye neempawu ezibalaseleyo zokuxhathisa ukubola xa kuthelekiswa neentsimbi ze-austenitic ezingenasici ezifana ne-304L kunye ne-316L. I-Duplex Steel S31803 Tube inokumelana nokugrumba okugqwesileyo ngenxa yekhabhoni ephantsi, enceda ukuthintela ukubola kwemigodi.

Imibhobho ifumaneka ngeendlela ezimbini, ingenamthungo kwaye idityanisiwe. Iityhubhu ezingenamthungo zenziwe ngaphandle kwe-welding, ngelixa iibhubhu ezidibeneyo zine-weld kunye nobude betyhubhu. Zombini ezi ntlobo zineenzuzo ngokuxhomekeke kwiimfuno zakho zesicelo, nangona kunjalo iibhubhu ezingenamthungo zisetyenziswa ngokubanzi ngenxa yamandla abo aphezulu kumlinganiselo wobunzima kunye nokukwazi ukumelana namaqondo obushushu aphezulu kuneetyhubhu ezidityanisiweyo.
