Iimfazwe zangaphandle ziyaqhubeka, kodwa uqoqosho lwelizwe luyaqhubeka nokwazisa imigaqo-nkqubo emihle, kwaye kwicala lemizi-mveliso, amaxabiso esinyithi afikelele kwinqanaba eliphezulu amaxesha amaninzi. IiBifocals zinyukile ngenxa yokwanda kwemfuno ngexesha lobushushu, inkxaso yeendleko ibinamandla, kwaye amaxabiso esinyithi aqhubekile nokunyuka. , uloyiko lwemfuno ephezulu yesiphelo luye lwanda, imisebenzi yokuhlaziya imarike inyukile, imveliso yentsimbi eluhlaza yemihla ngemihla iye yehla, ukungeniswa kwesinyithi kwehle, omnye umjikelo weefandesi zomhlaba uqalile, kwaye imakethi yendawo izinzile kwaye inamandla. Ngokwembono epheleleyo, amaxabiso esinyithi kulindeleke ukuba azinzile kwaye aqine ngomso.

I-Sanon Pipe Industry okwangoku inemibhobho yentsimbi elandelayo ekhoyo:

Umbhobho wentsimbi ongenamthungo weebhoyila eziphantsi neziphakathi - GB/T3087-200810#, esetyenziselwa imibhobho yomphunga eshushu kakhulu, imibhobho yamanzi abilayo, imibhobho yodonga epholiswe ngamanzi kunye nemibhobho yomphunga eshushu kwiibhoyila zelocomotive, imibhobho yomsi emikhulu, imibhobho yomsi emincinci kunye nemibhobho yezitena ze-arch, njl.njl. Izinto eziphambili: 10# 20#, inkqubo yokuvelisa: i-hot-rolled ihanjiswa ikwimeko yokuqengqeleka okushushu, i-cold-rolled (rolled) ihanjiswa ikwimeko yokunyangwa kobushushu.

Imibhobho yentsimbi engenamthungo yeebhoyila ezinoxinzelelo oluphezulu - GB/T5310-2017, injongo: Isetyenziswa kakhulu ukuvelisa intsimbi yesakhiwo sekhabhoni ekumgangatho ophezulu, intsimbi yesakhiwo se-alloy kunye nemibhobho yentsimbi engenasici engashukumiyo engatshiyo yentsimbi yemibhobho yebhoyila yomphunga enoxinzelelo oluphezulu nangaphezulu. . Amanqanaba entsimbi yesakhiwo sekhabhoni ekumgangatho ophezulu aquka i-20g, i-20mng, kunye ne-25mng, kwaye amanqanaba entsimbi yesakhiwo se-alloy aquka i-15mog, i-20mog, i-12crmog, i-15crmog, i-12cr2mog, i-12crmovg, i-12cr3movsitib, njl.
