Munzvimbo dziri kuramba dzichichinja dzekuvaka nemaindasitiri, kudiwa kwezvinhu zvemhando yepamusoro ndiko kunonyanya kukosha. Pakati pezvinhu izvi, machubhu ekuvaka ane chikamu chisina chinhu ave mhinduro inoshandisika kune zvakasiyana-siyana zvekushandisa, kunyanya muminda yekuvaka, petrochemicals uye masisitimu ebhoyira anodziya zvakanyanya.
Pamberi peindasitiri iyi pane kambani inotungamira mukugadzira zvinhu iri muCangzhou, Hebei Province. Yakavambwa muna 1993, kambani iyi yakakura nekukurumidza nekufamba kwemakore, ichifukidza nzvimbo inosvika 350,000 square metres uye midziyo yese inosvika 680 miriyoni yuan. Iine vashandi 680 vakazvipira uye michina yakanaka kwazvo, kambani iyi inokwanisa kusangana nezvinodiwa nevatengi zvakasiyana-siyana.
Chimwe chezvinhu zvinoshamisa zvinopihwa nemugadziri uyu imhando dzakasiyana-siyana dzemachubhu emhando ye alloy, anowanikwa muhukuru hunotangira pamasendimita maviri kusvika makumi maviri nemana. Akagadzirwa nezvinhu zvepamusoro-soro zvakaita seP9 neP11, machubhu aya akanakira kushandiswa munzvimbo dzinopisa zvakanyanya. Mashandisirwo awo makuru anosanganisira nzvimbo dzinopisa mumaboilers ane tembiricha yepamusoro, economizers, headers, superheaters, uye reheaters. Uyezve, machubhu aya emhando ye alloy zvinhu zvakakosha muindasitiri ye petrochemical, uko kugara kwenguva refu uye kuramba mamiriro ekunze akaipisisa ndiko kwakakosha.
Kambani inogadziramapaipi ekuvaka ane chikamu chisina chinhuizvo zvinopa simba rakasiyana uye kugadzikana kune akasiyana mashandisirwo. Chimiro chazvo chakasiyana chinobvumira kugoverwa kwemitoro zvakanaka, izvo zvinobatsira zvikuru kumapurojekiti ekuvaka uko kusimba kwechivakwa kwakakosha. Ingave ichishandiswa mumafuremu ekuvaka kana sechikamu chemasisitimu akaomarara emaindasitiri, machubhu aya anopa kuvimbika uye mashandiro ayo mainjiniya nevagadziri vezvivakwa vanogona kuvimba nawo.
Chimwe chezvakanakira zvikuru zvemapaipi ekuvaka ane hollow section kugona kwawo kutsungirira kumanikidzwa kwakanyanya uye tembiricha. Izvi zvinoita kuti akwanise kushandiswa mumaindasitiri anoda zvinhu zvinogona kutsungirira mamiriro akaoma. Semuenzaniso, muindasitiri yemafuta, mapaipi aya anowanzo shandiswa nezvinhu zvinoparadza uye tembiricha yakanyanya. Mapaipi e alloy anopiwa nemugadziri uyu akagadzirwa kuti akwanise kutsungirira matambudziko akadaro, zvichiita kuti agare kwenguva refu uye ashande zvakachengeteka.
Uyezve, kushandiswa kwakasiyana-siyana kwemachubhu ekuvaka ane chikamu chisina kuvharwa hakungogumiri mumaindasitiri chete. Ari kushandiswawo zvakanyanya mukugadzira zvivakwa, uko kutaridzika kwawo kwakanaka uye zvakanakira zvivakwa zvinogona kuwedzera chitarisiko chepurojekiti. Kubva pazvivakwa zvemazuva ano kusvika kumabhiriji matsva, machubhu aya ari kuva chinhu chakakosha pakuvaka kwemazuva ano.
Zvose pamwe chete, machubhu ekuvaka ane hollow section akagadzirwa nemugadziri uyu weCangzhou anomiririra musanganiswa wemhando yepamusoro, kugara kwenguva refu, uye kushanduka-shanduka. Nehuwandu hwemachubhu e alloy anotangira pamasendimita maviri kusvika makumi maviri nemana, pamwe chete nemagiredhi akadai seP9 neP11, kambani iyi inokwanisa kushandira maindasitiri akasiyana-siyana akadai sema boiler ane tembiricha yepamusoro uye petrochemicals. Sezvo kudiwa kwezvinhu zvakavimbika uye zvinoshanda zvakanyanya kuri kuramba kuchikura, mugadziri uyu akagadzirira kusangana nematambudziko enyika yanhasi uye kuona kuti vatengi vake vanowana zvigadzirwa zvakanakisa. Ingave ichishandiswa mukuvaka, mashandisirwo emaindasitiri kana magadzirirwo ekuvaka matsva, machubhu ekuvaka ane hollow section pasina mubvunzo chikamu chakakosha chekuumba remangwana rezvivakwa.
