Hupenyu hwesespiral simbi pombiine hukama ne decarburization, kana iyo yepasi decarburize, simba repamusoro uye kupfeka kuramba kunoderedza yakanangana nehupenyu hwekushandiswa kwezuva nezuva.Muchiito chekurapa kwekupisa, inofanira kunge iri kuedza kusarega masvingo emukati nekunze uye akazarurirwa kumhepo.Iyo inokonzeresa yepakati spiral simbi pamusoro decarburization inonyanya oksijeni, mhute yemvura uye gasi oxidizing senge kabhoni dhaikisaidhi, kana pamusoro peiyo coil uye gasi rinopisa richisangana necoil zvinokonzeresa oxidation uye decarburization, saka, kutonga kwekabhoni dhaikisaidhi mukati. vira uye chikamu checarbon monoxide chakakosha zvikuru.Muchokwadi, iyo spiral simbi yekugadzira choto inodzivirira yenitrogen yakawedzerwa inoshanda zvakanyanya, imwe yenitrogen oxide gasi inogona kuparadzirwa kuderedza spiral simbi decarburization.

Kuti uwedzere hupenyu hwe spiral simbi pombi, saka iyo huru nzira ye spiral welded pombi ndeiyi:

(1) kugadzirwa kwechubhu hombe-dhayamita gobvu-yakavakirwa madziro kuitira kuvandudza kugona kumirisana nekuwedzera kwekumanikidza, kunyanya spiral welded pombi;

(2) kuvandudzwa kwemhando itsva dzesimbi, tekinoroji yekunyungudutsa kuvandudza mwero wekugadzira uye yakanaka yemhando yespiral welded pombi welding, inoshandiswa zvakanyanya kudzora kutenderera nekukunguruka mushure mekupisa kwekupisa, kuitira kuti irambe ichivandudza kuoma uye weldability. muviri wepombi;

(3) kugadzira mapaipi akavharidzirwa, akadai semadziro emukati mechubhu yakavharwa ne-anti-corrosion layer, kwete kungowedzera hupenyu nekuvandudza kutsetseka kwemadziro emukati, kuderedza kukwesha kwemvura, kuderedza huwandu hwenamo uye tsvina, kuderedza nhamba yenguruve, kuderedza mari yekuchengetedza.

(4) dhizaini uye kugadzirwa kwezvivakwa zvesimbi zvitsva, senge kaviri spiral welded pombi, iyo iri hafu yeukobvu hwemadziro kuita kaviri welded simbi pombi, kwete chete kusimba kwakakwira kupfuura kukora kwakafanana kwechubhu imwe chete, uye hazvizoratidzi kukundikana kudiki.Paunenge uchishandisa spiral welded pombi kutevedzera mamwe maitiro ekugadzira uye kugadzirisa tekinoroji, kudzora kwakasimba kwemaitiro ekugadzira, ine kunaka kwakanaka uye kuita, inoita basa rakakosha mukushandiswa nekusimudzira.Development of space spiral welded pombi yakakura, kusimudzira maindasitiri akasiyana neminda uye kukwidziridzwa, zvinobudirira kuderedza dambudziko rekuvaka nekuvaka, kuona kukosha kwavo kwakazara.
