Iyo boiler isina musono chubhu yekugadzira nziraIyo boiler ine rudzi rweseamless chubhu. Nzira dzekugadzira uye chubhu isina musono zvakafanana, asi iva nechikumbiro chakasimba chekugadzira simbi inoshandiswa mupombi yesimbi. Zvinoenderana nekushandiswa kwetembiricha inogona kukamurwa kuita maviri bhailer chubhu uye yakanyanya kudzvanywa boiler chubhu.1, muchidimbu ye(1) nzira yekugadzira: (1) general boiler seamless chubhu tembiricha iri pasi pe450 ℃, pombi yemumba inonyanya kushandisa gumi. , 20 kabhoni simbi inopisa yakakungurutswa kana inotonhora inodhonzwa chubhu kugadzira.(2) high pressure boiler machubhu asina musono anowanzo ari mutembiricha yakakwira uye mamiriro ekumanikidza, kana uchishandisa pombi pasi pechiito chetembiricha yeflue gasi nemvura. mhute, oxidation uye ngura zvichaitika. Zvinodiwa zvepombi yesimbi ine simba rinodambuka zvakanyanya, kusimba kwekusaora kweoxidation, uye kuve nekugadzikana kwakanaka kwesangano.(2) shandisa:(1) bhailer yechubhu isina musono ndiyo inonyanya kushandiswa kugadzira chubhu yemumadziro emvura, pombi yemvura, chubhu inopisa kwazvo, bhaira relocomotive. pombi inopisa zvikuru, hombe nediki pombi uye chubhu arch zvidhinha, zvichingodaro.(2) high pressure boiler seamless chubhu inonyanya kushandiswa kugadzira high-pressure uye ultrahigh-pressure. boiler superheater machubhu, reheater chubhu, airway main steam pombi, nezvimwe.

Kushandisa boiler isina musono chubhu

1 anoshandiswa kugadzira high-pressure uye ultrahigh-pressure boiler superheater tubes, reheater chubhu, airway main steam pombi, etc.(3) GB3087-82 yakaderera yepakati pressure boiler simbi isina musono. machubhu uye GB5310-95 "high pressure boiler seamless simbi chubhu" mutemo. Chitarisiko chemhando: simbi chubhu mukati uye kunze kwepamusoro hazvibvumidzwe kuve nekutsemuka, kupeta, kupeta, mavanga, delamination uye hairline. Izvi zvinokanganisa zvichabviswa zvachose. Bvisa kutsauswa kwakashata, kudzika hakupfuurire kukora kwemadziro kucheneswa mukukobvu chaiko kwemadziro hakuzove kushoma pane ukobvu hwemadziro hunobvumirwa. Weight calculation method of boiler seamless tube theory: – wall thickness (diameter) * 0.02466 * madziro ukobvu.
