Ubomi beumbhobho wentsimbi ejikelezayoinobudlelwane ne-decarburization, ukuba umphezulu we-decarburize, amandla omphezulu kunye nokumelana nokunxiba kuya kunciphisa ifuthe elithe ngqo kubomi bokusetyenziswa kwemihla ngemihla.Kwinkqubo yonyango lokushisa, kufuneka uzame ukungavumeli iindonga zangaphakathi nangaphandle kwaye zivelele emoyeni.Isiphumo sentsimbi ephakathi kwentsimbi yomphezulu we-decarburization yeyona ioksijini, umphunga wamanzi kunye nerhasi ene-oxidizing efana nekharbon diokside, xa imiphezulu yecoil kunye negesi eshushu inxibelelana necoil iya kubangela i-oxidation kunye ne-decarburization, ke ngoko, ulawulo lwekharbon diokside iziko kunye nomlinganiselo wekhabhon monoxide kubaluleke kakhulu.Enyanisweni, i-spiral steel forging furnace protective atmosphere ye-nitrogen yongezwa iyasebenza kakhulu, enye igesi ye-nitrogen oxide inokusasazwa ukunciphisa i-spiral steel decarburization.

Ukuze kwandiswe ubomi bombhobho wentsimbi ejikelezayo, ngoko ke eyona ndlela iphambili ye-spiral welded pipe zezi:

(1) ukuveliswa kwetyhubhu enkulu enodonga olungqingqwa ukuze kuphuculwe ukukwazi ukumelana noxinzelelo olwandisiweyo lombhobho we-spiral welding;

(2) ukuphuhliswa kweentlobo ezintsha zentsimbi, iteknoloji yokunyibilikisa ukuphucula umgangatho wemveliso kunye nomgangatho olungileyo spiral welding welding welding, esetyenziswa ngokubanzi ukulawula ukuqengqeleka kunye nokuqengqeleka emva kwenkqubo yonyango lobushushu, ukuze kuphuculwe ngokuqhubekayo ukuqina kunye nokuwelda. umzimba wombhobho;

(3) ukuphuhlisa imibhobho egqunyiweyo, efana nodonga lwangaphakathi lwetyhubhu eqatywe nge-anti-corrosion layer, kungekuphela nje ukwandisa ubomi kunye nokuphucula ukuguda kodonga lwangaphakathi, ukunciphisa ukukhuhlana kolwelo, ukunciphisa umthamo we-wax kunye nokungcola, ukunciphisa i-wax kunye nokungcola. inani leehagu, ukunciphisa iindleko zokugcina.

4 kwaye ayisayi kubonakala ingaphumeleli brittle.Xa usebenzisa umbhobho we-spiral welding ukuba ulandele imigangatho ethile yemveliso kunye nobuchwepheshe bokucubungula, ulawulo olungqongqo lwenkqubo yemveliso, inomgangatho omhle kunye nokusebenza, idlala indima ebalulekileyo ekusetyenzisweni nasekukhuthazeni.Uphuhliso isithuba spiral welded umbhobho mkhulu, uphuhliso amashishini ezahlukeneyo kunye namasimi kunye nokukhuthazwa, ngempumelelo ukunciphisa inkathazo yokwakha kunye nesakhiwo, ukuqonda ixabiso labo elipheleleyo.
