GB/T9948seamless simbi pombi yepetroleum kutsemuka ipombi isina musono yakakodzera machubhu echoto, zvinopisa zvinopisa uye mapaipi mumafuta epetroleum. Yepamusoro-mhando kabhoni yakarongeka simbi, alloy structural simbi uye simbi isina kupisa-inodzivirira simbi yakakwirira-kudzvanywa isina musono mapaipi anoshandiswa kugadzira chiutsi boiler pombi dzekumanikidza kwakanyanya uye pamusoro. Aya mapombi ebhailer anoshanda pasi pekushisa kwakanyanya uye kumanikidzwa, uye mapaipi anooneswa nehutsi hwekushisa. Oxidation uye corrosion ichaitikawo pasi pekuita kwegasi uye mhute yemvura. Nokudaro, pombi dzesimbi dzinodiwa kuti dzive nesimba rinogara rakakwirira, kukwirira kweoxidation kuramba, uye kugadzikana kwakanaka kwesangano. Pamusoro pekuita shuwa kuumbwa kwemakemikari uye michina zvivakwa, yakakwira-kudzvanya boiler pombi dzinofanirwawo Kuita hydraulic pressure test imwe neimwe, kusanganisira yekuwedzera uye flattening bvunzo. High-pressure seamless pombi inounzwa mumamiriro ekupisa.
Petroleum inoputika pombi kugadzira uye nzira dzekugadzira:

① Kazhinji, tembiricha yebasa yemapombi esimbi isina musono iri pasi pe450°C. Mapombi emumba anonyanya kugadzirwa neNo.10, Nha.20,12CrMo, 15CrMo, 12CrlMo, 12CrlMoV, 12Cr5MoI, 12Cr9MoI, pombi dzinopisa kana pombi dzinodhonzwa nechando.

② GB9948 yakajairwa seamless simbi mapaipi anowanzo kuratidzwa kune yakanyanya tembiricha uye yakanyanya kudzvanywa mamiriro kana ashandiswa. Mapombi anozoita oxidize uye agoora pasi pekuita kwekushisa kwakanyanya kweflue gasi uye mhute yemvura. Mapombi esimbi anodiwa kuti ave nesimba rakasimba rekugara, kupikisa kwakanyanya kune oxidation uye ngura, uye kugadzikana kwakanaka kwechimiro.

shandisa:

① Kazhinji, mapaipi esimbi asina musono anonyanya kushandiswa kugadzira pombi dzemadziro emvura, pombi dzemvura dziri kufashaira, pombi dzinopisa kwazvo, pombi dzinopisa kwazvo dzemabhoilers emagetsi, pombi hombe uye diki dzeutsi uye arch zvidhinha pombi, nezvimwe.

②GB9948 pombi yesimbi isina musono ndiyo inonyanya kushandiswa kugadzira machubhu anopisa, machubhu ekudzoreredza, machubhu ekutungamira emhepo, mapaipi makuru ehutsi, nezvimwe.

GB9948 yakajairwa seamless simbi mapaipi akakamurwa kuita akajairwa boiler pombi uye yakakwira-kudzvanya boiler pombi zvinoenderana nekuita kwavo kupisa kwakanyanya. Angave akajairwa boiler machubhu kana yakakwira-kudzvanya boiler machubhu, anogona kukamurwa kuita akasiyana mapaipi esimbi zvinoenderana neavo akasiyana mashandisiro aanoda.
GB/T9948 isina musono simbi pombi, kunze dhayamita 10 ~ 426mm, rusvingo ukobvu 1.5 ~ 26mm. Iyo dhayamita yekunze uye ukobvu hwemadziro ehupfu hunopisa, machubhu mahombe eutsi, machubhu madiki eutsi uye arch zvidhinha machubhu anoshandiswa mulocomotive boilers anotsanangurwa neimwe nzira.

Hunhu hwekuonekwa: Hapana kutsemuka, kupeta, mipumburu, scabs, delamination uye mitsara yebvudzi zvinotenderwa mukati uye kunze kwekunze kwepombi dzesimbi. Izvi zvinokanganisa zvinofanira kubviswa zvachose. Kucheneswa kwakadzika hakuzopfuure kutsauka kwakashata kweiyo zita remadziro ukobvu, uye iyo chaiyo yemadziro ukobvu panzvimbo yekuchenesa haizove shoma pane yakaderera inotenderwa madziro ukobvu.
