Ukukhethwa kwezixhobo zeFlange zeStainless Steel

Ukukhethwa kwezinto zeflange zentsimbi engagqwaliyo kufuneka kusekelwe kuvavanyo olupheleleyo lwemeko yokusetyenziswa, imeko-bume erhabaxa, ubushushu, uxinzelelo, kunye nezinye iimeko. Nazi izinto eziqhelekileyo kunye neemeko ezifanelekileyo:

Intsimbi Engagqwaliyo engama-304 (06Cr19Ni10)
Iimpawu: Iqulethe i-18% ye-chromium kunye ne-8% ye-nickel, ayinayo i-molybdenum, ayimelani nokugqwala ngokubanzi, kwaye ingabizi kakhulu.
Iimeko ezifanelekileyo: Iindawo ezomileyo, ukulungiswa kokutya, ukuhombisa izakhiwo, izindlu zezixhobo zasekhaya, njl.
Imida: Inokugqwala kwiindawo ezinee-ion ze-chloride (umz., amanzi olwandle, amanzi edamini lokudada).

Intsimbi Engagqwaliyo engama-316 (06Cr17Ni12Mo2)
Iimpawu: Iqulethe i-2.5% ye-molybdenum, ukumelana okuphuculweyo nokugqwala kwe-chloride ion, ukumelana nobushushu obuphezulu (≤649℃).
Iimeko ezifanelekileyo: Izixhobo zaselwandle, imibhobho yeekhemikhali, izixhobo zonyango, iindawo ezinobushushu obuphezulu kunye neendawo ezinoxinzelelo oluphezulu.

304L/316L (Iinguqulelo zeKhabhoni ePhantsi)
Iimpawu: Umxholo wekhabhoni ≤0.03%, ukumelana okuphezulu kokugqwala phakathi kweegranular xa kuthelekiswa nomgangatho we-304/316.
Iimeko ezifanelekileyo: Izixhobo ezifakwe kwi-welding yobushushu obuphezulu okanye ezifuna ukumelana nokugqwala ixesha elide (umz., amandla enyukliya, amayeza).

Ezinye izixhobo
347 Intsimbi Engagqwaliyo (CF8C): Iqulethe i-niobium, efanelekileyo kwiindawo ezinobushushu obuphezulu kakhulu (≥540℃).
Intsimbi Engagqwaliyo Ephindwe Kabini: Idibanisa iipropati ze-austenitic kunye ne-ferritic, inamandla aphezulu, ifanelekile kwiimeko zolwandle olujulileyo okanye ezixinezelekileyo.

Iingcebiso zoKhetho
Ukusetyenziswa ngokubanzi kwimizi-mveliso: Ukhetha i-304, ixabiso liphantsi kwaye ihlangabezana neemfuno ezininzi.
Iindawo eziGcolisayo: Khetha i-316 okanye i-316L, i-molybdenum iyamelana ngempumelelo nokugqwala kwe-chloride ion.
Iindawo ezikhethekileyo zobushushu obuphezulu/uxinzelelo oluphezulu: Khetha izinto ezinekhabhoni ephantsi okanye ezimbini ngokusekelwe kubushushu obuchaziweyo.
