1. Yintoni ityhubhu yebhoyila?
I-Boiler tube ibhekisela kwintsimbi eneziphelo ezivulekileyo kunye necandelo elingenalutho, kwaye ubude bayo bukhulu kunobupheripheri.Ngokwendlela yokuvelisa, inokwahlulwa ibe ngumbhobho wentsimbi ongenamthungo kunye nombhobho wentsimbi odityanisiweyo.Ubukhulu bodonga buthetha uluhlu olubanzi lwemilinganiselo, ukusuka kwiityhubhu ze-capillary ezinobubanzi obuncinci ukuya kwiityhubhu ezinobubanzi obuziimitha ezininzi.Imibhobho yentsimbi ingasetyenziselwa imibhobho, izixhobo ezishushu, ishishini loomatshini, ukuhlola i-petroleum geological, izitya, ishishini lemichiza kunye neenjongo ezikhethekileyo.
2. Ukuhlelwa
Iityhubhu zebhoyila zihlulwe zibe ziibhobho zebhoyila ngokubanzi kunyeiityhubhu zebhoyila zoxinzelelo oluphezulungokwentsebenzo yobushushu obuphezulu abayithwalayo, kwaye inokohlulwa ibe yimibhobho yentsimbi eyahlukeneyo ngokweemfuno zabo ezahlukeneyo.
3. Injongo yetyhubhu yebhoyila
① Iityhubhu zebhoyila ngokubanzi zisetyenziswa ikakhulu ukwenza iityhubhu eludongeni lwamanzi, iityhubhu zamanzi abilayo, iityhubhu zomphunga oshushu kakhulu, iityhubhu zomphunga ezishushu kakhulu kwiibhoyila zikaloliwe, iityhubhu ezinkulu nezincinci zomsi kunye neetyhubhu zezitena.
②Iityhubhu zebhoyila ezinoxinzelelo oluphezulu zisetyenziswa ikakhulu ukwenza iityhubhu zokufudumeza, iityhubhu zokufudumeza, iityhubhu zesikhokelo somoya, iityhubhu eziphambili zomphunga, njl.
4. Sebenzisa ibakala lentsimbi
(1) Umgangatho ophezulu we-carbon structural steel steelI-GB 5310 20G iThubhu yeBoiler yoxinzelelo oluphezulu, I-GB 5310 20MNG IiThubhu zeBoiler eziKhuselekileyo eziKhuselekileyo, i-GB 5310 25MNG Iityhubhu zeBoiler eziKhuselekileyo, njl njl.
(2) I-alloy yesakhiwo sentsimbiI-15CrMo i-Seamless Alloy Steel Pipe/Tube, 12Cr1MoV High Pressure Seamless Ingxubevange Steel Boiler Tube,Din 17175 16Mo3 iThubhu yeBoiler yentsimbi engenamthungo ePhezulu, njl.
(3) Ukongeza ekuqinisekiseni ukubunjwa kweekhemikhali kunye neempawu zoomatshini, i-1Cr18Ni9 kunye ne-1Cr18Ni11Nb iityhubhu zebhoyila ezidla ngokusetyenziswa kwintsimbi erusayo nekwaziyo ukumelana nobushushu kufuneka zifakwe kwiimvavanyo ze-hydrostatic, kunye novavanyo lokuvutha kunye nokucaba.Umbhobho wensimbi uhanjiswa kwisimo sokushisa.Ukongeza, kukho iimfuno ezithile ze-microstructure, ubungakanani beengqolowa, kunye ne-decarburized layer yombhobho wensimbi ogqityiweyo.
