Intshayelelo yemveliso

Imibhobho yentsimbi yesichumiso sekhemikhali isetyenziswa ikakhulu ukwenza umgangatho ophezulu wekhabhoni yentsimbi yesakhiwo, ingxubevange yentsimbi yesakhiwo kunye nentsimbi ekwaziyo ukumelana nobushushu obuphezulu-noxinzelelo olungenamthungo kwimibhobho yebhoyila enoxinzelelo oluphezulu kwaye ezi tyhubhu zebhoyila zisebenza phantsi kobushushu obuphezulu. kunye noxinzelelo oluphezulu, kunye neetyhubhu ziya kuba ne-oxidized kunye ne-corrod phantsi kwesenzo se-high-temperature flue gas kunye ne-steam.Ngoko ke, iityhubhu zentsimbi zifuneka ukuba zibe namandla ahlala ixesha elide, ukumelana ne-oxidation ephezulu, kunye nokuzinza okuhle kombutho.Amanqanaba ensimbi asetyenzisiweyo: umgangatho ophezulu we-carbon structural steel grade 20G, 20MnG, 25MnG;I-alloy structural steel grade 15MoG, 20MoG, 12CrMoG, 15CrMoG, 12Cr2MoG, 12CrMoVG, 12Cr3MoVSiTiB, njl;I-1Cr18Ni9 eqhelekileyo kunye ne-1Cr18Ni11Nb iityhubhu zebhoyila zoxinzelelo oluphezulu ezenziwe ngomhlwa kunye nentsimbi ekwaziyo ukumelana nobushushu ziya kuxhomekeka kuvavanyo lwe-hydrostatic, ukuvutha kunye novavanyo lokucaba enye enye ngaphezu kokuqinisekisa ukwakheka kweekhemikhali kunye neempawu zoomatshini.Iityhubhu ezikhethekileyo zetsimbi zesichumisi sekhemikhali ziya kuhanjiswa kwimeko yonyango lobushushu.

Indawo esebenzayo

Umbhobho okhethekileyo wesichumisi (i-GB6479-2000) yintsimbi ephezulu ye-carbon structural iron kunye ne-alloy steel seamless steel pipe ilungele izixhobo zekhemikhali kunye nemibhobho enobushushu obusebenzayo be-40 ~ 400 ℃ kunye noxinzelelo lokusebenza lwe-10 ~ 30Ma.

Umbhobho we-alloy woxinzelelo oluphezulu lwezixhobo zesichumisi (GB6479-2000) yintsimbi esemgangathweni ye-carbon structural steel kunye ne-alloy steel seamless steel pipe ilungele izixhobo zekhemikhali kunye nemibhobho enobushushu obusebenzayo - 40 ~ 400 ℃ kunye noxinzelelo lokusebenza lwe-10 ~ 30Ma.

Intshayelelo yemveliso

(1) Indlela yokuvelisa:

①Ubushushu bokusetyenziswa kwemibhobho yentsimbi yesichumisi ingaphantsi kwama-450 ℃, kwaye imibhobho yasekhaya yenziwa ikakhulu ngemibhobho yentsimbi edityanisiweyo eyi-10 # kunye ne-20 #.

②Ipayipi ekhethekileyo yensimbi yesichumisi isoloko isetyenziswa phantsi kobushushu obuphezulu kunye noxinzelelo oluphezulu, kwaye umbhobho uya kuba ne-oxidized kwaye ugxumeke phantsi kwesenzo se-high-temperature flue gas kunye nomphunga wamanzi.Umbhobho wensimbi kufuneka ube namandla aphezulu, i-oxidation ephezulu kunye nokumelana nokugqwala, kunye nokuzinza okuhle kwentlangano.

(2) Injongo:

①Imibhobho yentsimbi yesichumiso sekhemikhali isetyenziswa ikakhulu ukwenza imibhobho eludongeni lwamanzi, imibhobho yamanzi abilayo, imibhobho yomphunga eshushu kakhulu, imibhobho yomphunga eshushu kakhulu kwizibilini zikaloliwe, imibhobho yomsi emikhulu nemincinci kunye nemibhobho yezitena zearch.

②Umbhobho wentsimbi osetyenziselwa isichumisi ngokukodwa usetyenziselwa ukwenza umbhobho weheater, umbhobho wokufudumeza, umbhobho womoya, umbhobho oyintloko womphunga, njl.
