Mokhoa oa ho netefatsa polokeho ea ho sebelisa li-boiler tsa khatello e phahameng
Li-tubes tsa boiler li sebelisoa libakeng tsa khatello e phahameng.E sebelisoa haholo liphaepheng tsa khase ea tlhaho le oli le khase.Lisebelisoa tse sebelisoang hangata li kenyelletsa:15CrMo Alloy Steel Tube,16Mo3 Alloy Seamless Steel Pipe,12Cr1MoV Alloy Seamless Steel Tube,20G Alloy Seamless Boiler Pipe.Ke tlhahlobo ea mofuta ofe e lokelang ho etsoa pele ho sebelisoa tube ea boiler ho netefatsa tšebeliso e sireletsehileng?
1. Ela hloko ka ho khetheha ha u kopanyali-tubes tsa boiler tse nang le khatello e phahameng.U se ke ua ba thata haholo ho qoba ho senya deformation e kopanetsoeng le ho senya mohaho, ho baka ho lutla le ho etsa hore e se ke ea sebelisoa.
2. Sena sea hlokahala bakeng sa khatello ea pele ea teko (ke ho hlahloba khatello ea tube ea boiler) (a).Khatello ea tube e khubelu ke 15000 0psi.
(b) Ha khatello e nyolohela ho (a) 15000 0pSi kapa (b) 800 0pSi, khatello ea tube e ntšo ke 800 0pSi, khatello e emisoa ka metsotso e ka bang 2 ho ea ho metsotso ea 5, ebe e hlahlojoa hore na ho na le sebōpeho sefe. , joalo ka mpa e kholo, e lutla., tube, haeba e sa etsahale, tsena tsohle li tloaelehile, 'me haeba E ke ntho e sa tloaelehang, tube ea boiler e ke ke ea sebelisoa, e lokela ho thibeloa ka thata.E lokela ho khutlisetsoa ho morekisi kapa khamphani ea thekiso.

Ho hlokomela le ho boloka li-tubes tsa boiler tse nang le khatello e phahameng
1. Tlhokomelo ea tube e nang le khatello e phahameng ea khatello e bonolo haholo, hafeela e hloekisoa ka sebopeho se chitja le se chitja se nang le mochine oa ho hloekisa (methanol) ka har'a tube ho fihlela e hloekisoa, ebe e hloekisoa ka mokhoa o hloekileng oa ho hloekisa; ka ho khetheha ho siea ntho e 'ngoe ea ho hloekisa ka har'a tube.
2. Ha o paka li-boiler tubes, ha ho na theolelo kapa likhato tse 90 kapa pokello e leketlileng, hobane ho phutha kapa ho bokella likhato tse 90 ho tla senya mohaho le nako ea khefu e tla fetoha likhato tse 90, kahoo ho kgothaletswa ho sebelisa polokelo e chitja ho thibela ho emisoa.
