Hondo dzekunze dziri kuramba dzichienderera mberi, asi hupfumi hwenyika huri kuramba huchiunza mitemo yakanaka, uye kudivi remaindasitiri, mitengo yesimbi yakwira zvakanyanya kakawanda. MaBifocal akwira nekuda kwekuwedzera kwekudiwa kwesimbi munguva yekupisa, rutsigiro rwemari rwave rwakasimba, uye mitengo yesimbi yakaramba ichikwira. , kutya kwekudiwa kukuru kwesimbi kwakawedzera, mabasa ekuzadza musika akawedzera, kugadzirwa kwesimbi isina kucheneswa zuva nezuva kwaderera, kutengeswa kwesimbi kunze kwenyika kwaderera, imwezve nguva yekutengeswa kwevhu kwatanga, uye musika wekutengesa wakadzikama uye wakasimba. Kubva pamaonero akazara, mitengo yesimbi inotarisirwa kugadzikana uye yakasimba mangwana.

Sanon Pipe Industry parizvino ine mapaipi esimbi anotevera aripo:

Pombi yesimbi isina musono yemaboilers ane simba shoma nepakati - GB/T3087-200810#, inoshandiswa pamapaipi emvura inopisa zvakanyanya, mapaipi emvura ari kufashaira, mapaipi emadziro anotonhodzwa nemvura uye mapaipi emvura inopisa emabhaira emota, mapaipi makuru eutsi, mapaipi madiki eutsi uye mapaipi ezvidhinha zvearch, nezvimwewo.
