Izimpi zakwamanye amazwe ziyaqhubeka, kodwa i-macroeconomics yasekhaya iyaqhubeka nokuletha izinqubomgomo ezivumayo, futhi ngasohlangothini lwezimboni, amanani e-iron ore akhuphuke izikhathi eziningi.Ama-Bifocals akhuphukile ngenxa yesidingo esikhulayo phakathi nenkathi yokushisa, ukusekelwa kwezindleko kuye kwaba namandla, futhi amanani ensimbi aqhubekile nokukhuphuka., ukwesaba kwesidingo esikhulu sokugcina kuye kwakhula, imisebenzi yokugcwalisa izimakethe inyukile, ukukhiqizwa kwensimbi engahluziwe kwansuku zonke kwehlile, ukuthengwa kwensimbi yensimbi kwamanye amazwe kwehlile, umjikelezo owodwa wokuthengiswa kwenhlabathi usuqalile, futhi imakethe yendawo izinzile futhi iqinile.Ngokombono obanzi, amanani ensimbi kulindeleke ukuthi azinze futhi aqine kusasa.

Imboni ye-Sanon Pipe njengamanje inalawa mapayipi ensimbi alandelayo esitokweni:

Ipayipi lensimbi elingenamthungo lama-boiler anengcindezi ephansi naphakathi - I-GB/T3087-2008I-10 #, esetshenziselwa amapayipi e-steam ashisa kakhulu, amapayipi amanzi abilayo, amapayipi odongeni apholile ngamanzi kanye namapayipi ashisayo ashisayo ama-boilers e-locomotive, amapayipi amakhulu omusi, amapayipi amancane omusi kanye namapayipi wezitini ze-arch, njll.Izinto eziyinhloko: 10# 20#, inqubo yokukhiqiza: i-hot-rolled ihanjiswa esimweni esishisayo, i-cold-rolled (igoqiwe) ihanjiswa esimweni esiphethwe ukushisa.

Amapayipi ensimbi angenamthungo amaboilers anengcindezi ephezulu - I-GB/T5310-2017, inhloso: Isetshenziselwa kakhulu ukukhiqiza insimbi yesakhiwo sekhabhoni yekhwalithi ephezulu, insimbi yesakhiwo sealloy kanye namapayipi ensimbi engenamthungo evikela ukushisa kumapayipi okubhayela isitimu wengcindezi ephezulu nangaphezulu..Ikhwalithi ephezulu ye-carbon structural steel amamaki ahlanganisa i-20g, i-20mng, ne-25mng, futhi amamaki ensimbi ye-alloy ahlanganisa i-15mog, i-20mog, i-12crmog, i-15crmog, i-12cr2mog, i-12crmovg, i-12cr3movsitib, njll.
