Iimfazwe zamazwe angaphandle ziyaqhubeka, kodwa i-macroeconomics yasekhaya iyaqhubeka nokuzisa imigaqo-nkqubo efanelekileyo, kwaye kwicala lezoshishino, amaxabiso e-iron ore abethe phezulu amaxesha amaninzi. I-Bifocals inyuke iqhutywe yimfuno eyongeziweyo ngexesha lokufudumala, ukuxhaswa kweendleko kuye kwaqina, kwaye amaxabiso ensimbi aqhubekile nokunyuka. , ukwesaba kweemfuno eziphezulu ze-terminal kuye kwaqina, imisebenzi yokuzaliswa kweemarike iye yanda, imveliso yentsimbi ekrwada yemihla ngemihla iye yancipha, ukungeniswa kwentsimbi yentsimbi kunciphile, ifandesi enye yeefandesi zomhlaba sele iqalile, kwaye imarike yendawo izinzile kwaye yomelele. Ukusuka kumbono obanzi, amaxabiso ensimbi kulindeleke ukuba azinzile kwaye aqine ngomso.

Umzi mveliso weSanon Pipe ngoku unale mibhobho yentsimbi ilandelayo esitokhweni:

Umbhobho wensimbi ongenamthungo kwiibhoyila eziphantsi kunye neziphakathi - I-GB/T3087-2008I-10 #, esetyenziselwa imibhobho yomphunga eshushu kakhulu, imibhobho yamanzi abilayo, imibhobho yodonga epholileyo ngamanzi kunye nemibhobho yomphunga eshushu kwiibhoyili ze-locomotive, iipayipi ezinkulu zomsi, imibhobho emincinci yomsi kunye nemibhobho yezitena ze-arch, njl.
