Umenzi wePipe/Tube Tubing yentsimbi engatyiwayo, umnini-zabelo, umthengisi wePipe ye-SS eTshayina.
Icandelo leeTubhu kunye neePipe eziWelded zeNtsimbi Engagqwaliyo linemigca emibini yokuwelda yokwenza iityhubhu kunye neepayipi eziweldiweyo. IiTubhu/iiPipe eziWelded zeNtsimbi Engagqwaliyo zenziwe kwiContinuous Tube Mill kusetyenziswa inkqubo yokuwelda yeMultitorch TIG (Tungsten Inert Gas). Iistrips zentsimbi engagqwaliyo ezisemgangathweni ophezulu ezineemiphetho ezinqunqiweyo zinikwa kwi-tubes mill emva kokuhlolwa komgangatho. I-Strip idlula kwiiseti ezahlukeneyo zeeroller ezifakwe kwi-mill ngokobungakanani obufunekayo. Le strip iguqulwa kancinci kancinci ibe yimilo yetafile. Ii-Edges ziweldwa kusetyenziswa inkqubo yokuwelda ye-TIG yiyunithi yokuwelda efakwe kwii-mills, ibhidi yangaphakathi yokuwelda isuswa ngoko nangoko ngomatshini wokususa ibhidi kwi-intanethi. IiTubhu/iiPipe eziRholiweyo eziveliswa ngolu hlobo zinqunyulwa zibe bubude obufunekayo. Oku kunyangwa ngakumbi ngobushushu (annealing) emva kokucoca ngokufanelekileyo ukususa uxinzelelo olubandakanyiweyo ngexesha lokwenziwa kunye nokuwelda kunye nokubuyisela isakhiwo sokuqala sengqolowa.
Unyango lobushushu lwenziwa kwisithando somlilo esijikelezayo esifakelwe isilawuli sobushushu kunye nerekhoda. Emva konyango lobushushu, iityhubhu/iipayipi ziyalungiswa kwaye zifakwe kwi-pickling ukuze kususwe isikali kumphezulu. Ukuba ubungakanani bokugqibela abunakuveliswa ngqo kwi-mill, obufanayo buveliswa ngumsebenzi wokutsala obandayo. Ukuze ityhubhu/ipayipi ifanelekele ukutsala obandayo, igqunywa ngesisombululo se-oxalate kunye ne-shop esisebenza njenge-lubricant kwaye sinciphise ukungqubana ngexesha lokutsala. Kumsebenzi wokutsala, ityhubhu/ipayipi itsalwa phezu kwebhentshi yokutsala kusetyenziswa izixhobo ezichanekileyo oko kukuthi ii-Dies Plugs ngokweemfuno zobukhulu obugqityiweyo. Ityhubhu/ipayipi etsaliweyo inyangwa ngobushushu, i-pickling kunye neminye imisebenzi njengoko kuchaziwe apha ngasentla emva kokucoca umphezulu.
Iipayipi/iityhubhu ezigqityiweyo ziphawulwe ngomatshini wokuMakisha iJet osebenzisa i-inki yekhompyutha. Ipayipi/ityhubhu nganye iphawulwe 'njengoMgangatho woKwenza'. Udidi lwezinto, Ubungakanani, Inombolo yobushushu, Isitampu searhente yohlolo yomntu wesithathu ukuze ihambelane neSatifikethi sethu soVavanyo. Iipayipi/iipayipi ezigqityiweyo eziveliswayo ngaloo ndlela zivavanyelwa kwaye zihlolwe umgangatho ngendlela eyahlukeneyo, kulandele ukupakishwa nokuthunyelwa ngokufanelekileyo.
