Isikhokelo sobunjineli ekukhetheni ityhubhu yentsimbi echanekileyo

Injineli inokhetho oluninzi xa kuziwa ekukhetheni ityhubhu yentsimbi efanelekileyo kuso nasiphi na isicelo. Amabanga 304 kunye ne-316 i-tubing yensimbi engenasici zezona zisetyenziswa ngokuqhelekileyo. Nangona kunjalo, i-ASTM ikwabonelela ngeenjineli ngesona sisombululo silungileyo kwizicelo zabo. Ngokulandela izikhokelo ezichaziweyo, ihlangabezana neenjongo zohlahlo lwabiwo-mali ngelixa isabonelela ngentsebenzo efunekayo kubomi bemveliso.

Nokuba ukhetha i-seamless okanye i-welded
Xa ukhetha imathiriyeli yombhobho, kubalulekile ukwazi ukuba ifanele ingenamthungo okanye idityaniswe. Ityhubhu yentsimbi engenamthungo engama-304 yenziwe ngemathiriyeli eyaziwayo ekumgangatho ophezulu. Iityhubhu ezingenamthungo zenziwe nge-extrusion, inkqubo yokucheba ubushushu obuphezulu, okanye ukugqobhoza okujikelezayo, inkqubo yangaphakathi yokukrazula. Iityhubhu ezingenamthungo zihlala zibonelelwa ngobuninzi bodonga oluphakamileyo ukuze zikwazi ukumelana noxinzelelo oluphezulu.
Ityhubhu edityanisiweyo yenziwa ngokuqengqeleka ubude bentsimbi ibe yicylinder, emva koko ifudunyezwe kwaye ihlanganise imiphetho kunye ukwenza ityhubhu. Ikwadla ngokungabizi kakhulu kwaye inamaxesha amafutshane okukhokela.

IINGQWINGA NGEZOQOQOSHO
Amaxabiso ahluka kakhulu ngokuxhomekeke kubungakanani obuthengiweyo, ukufumaneka kunye ne-OD-to-wall ratio. Ubonelelo kunye nemfuno yemathiriyeli yangaphandle inyuse amaxabiso kuyo yonke indawo. Amaxabiso e-nickel, ubhedu kunye ne-molybdenum onke avukile kwaye awela ngokuphawulekayo kwiminyaka yamuva nje, enempembelelo enkulu kumaxabiso e-tube yensimbi. Ngenxa yoko, kufuneka kuthathelwe ingqalelo eyongezelelweyo xa kumiselwa uhlahlo lwabiwo-mali lwexesha elide kwii-alloys eziphezulu ze-alloy ezifana ne-TP 304, i-TP 316, i-cupro-nickel kunye ne-alloys equkethe i-6% molybdenum. I-alloys ye-nickel ephantsi njenge-Admiralty Brass, i-TP 439 kunye ne-super ferritics zizinzile kwaye ziqikeleleke.
