316l Steel Engenazimthungo uMbhobho wentsimbi
I-304 insimbi engenasici yinto eqhelekileyo kwintsimbi engatyiwayo, enoxinano lwe-7.93 g/cm³;ikwabizwa ngokuba yi-18/8 yensimbi engenasici kwishishini, oku kuthetha ukuba iqulethe ngaphezu kwe-18% ye-chromium kunye ne-nickel engaphezu kwe-8%;ukumelana nobushushu obuphezulu be-800 ℃, ukusebenza kakuhle kokusebenza, Ukuqina okuphezulu, kusetyenziswa kakhulu kushishino kunye nefenitshala yokuhombisa ishishini kunye nokutya kunye neshishini lezonyango.Nangona kunjalo, kufuneka kuqatshelwe ukuba xa kuthelekiswa nentsimbi eqhelekileyo ye-304, ukutya-grade 304 insimbi engenasici inesalathisi esingqongqo.Ngokomzekelo, inkcazo yamazwe ngamazwe ye-304 yensimbi engenasici ngokusisiseko yi-18% -20% ye-chromium, i-8% -10% ye-nickel, kodwa i-grade-grade 304 insimbi engenasici iqulethe i-chromium eyi-18 kunye ne-8% ye-nickel, evumela ukuguquguquka phakathi koluhlu oluthile, kwaye Nciphisa isiqulatho seentsimbi ezininzi ezinzima.Ngamanye amazwi, i-304 insimbi engenasici ayililo ibakala lokutya lama-304
Imibhobho yentsimbi engenamthungo yimibhobho yentsimbi ekwaziyo ukumelana nemithombo yeendaba edlayo ebuthathaka njengomoya, umphunga, namanzi, kunye nemithombo yeendaba edlayo ngokwemichiza efana neeasidi, iialkali, neetyuwa.Ikwabizwa ngokuba ngumbhobho wentsimbi onganyangekiyo.
Ukuxhatshazwa kwe-corrosion ye-stainless steel seamless pipes kuxhomekeke kwizinto ezixutywayo eziqulethwe kwintsimbi.I-Chromium yinto esisiseko yokuxhathisa ukubola kwentsimbi engatyiwayo.Xa umxholo we-chromium kwintsimbi ufikelela malunga ne-12%, i-chromium idibanisa ne-oksijini kwindawo ephazamisayo ukuze yenze ifilimu ye-oxide encinci kakhulu (ifilimu ye-self-passivation) phezu kwentsimbi., Inokuthintela ukubola okuqhubekayo kwe-matrix yensimbi.Ukongeza kwi-chromium, izinto ezisetyenziswa ngokuqhelekileyo zokudibanisa kwimibhobho yensimbi engenasici ibandakanya i-nickel, i-molybdenum, i-titanium, i-niobium, ubhedu, i-nitrogen, njl.
Umbhobho wentsimbi engenamthungo yintsimbi ende engqukuva, esetyenziswa kakhulu kwipetroleum, imichiza, unyango, ukutya, ishishini lokukhanya, izixhobo zoomatshini kunye neminye imibhobho yoshishino kunye nenxalenye yesakhiwo soomatshini.Ukongeza, xa ukugoba kunye namandla okuhlamba afanayo, ubunzima bulula, ngoko ke bukwasetyenziswa ngokubanzi ekwenzeni amacandelo omatshini kunye nezakhiwo zobunjineli.Ikwasetyenziswa rhoqo ukuvelisa izixhobo ezahlukeneyo eziqhelekileyo, imigqomo, amaqokobhe, njl.
Inala manyathelo emveliso alandelayo:
a.Ukulungiswa kwentsimbi ejikelezayo;b.Ukufudumeza;c.Ukugqobhoza okushushu;d.Sika intloko;e.Ukuvunwa;f.Ukusila;g.Ukuthambisa;h.Ukuqengqeleka okubandayo;i.Ukunciphisa amafutha;j.Isisombululo sonyango lobushushu;k.Ukulungelelanisa;l.Sika ityhubhu;m.Ukuvunwa;n.Uvavanyo lwemveliso.
