Incoloy Alloy 803 PIPE

INCOLOY alloy 803 (UNS S35045), hlau-nickel-chromium alloy, yog tsim los siv rau hauv petrochemical, tshuaj thiab thermal ua daim ntaub ntawv. Cov nickel thiab chromium cov ntsiab lus ntawm alloy 803 yog siab dua cov INCOLOY alloys 800H thiab 800HT®. Qhov sib piv ntawm npib tsib xee, hlau thiab chromium yog sib npaug los muab cov khoom zoo tshaj plaws hauv qhov kub ntawm 1550 degree F (840 degree) txog 2100 degree F (1150 degree). Alloy 803 yog ib qho khoom siv tau zoo uas muab cov qib tshwj xeeb ntawm kev kub siab corrosion kuj hauv oxidation, sulfidation thiab carburization ib puag ncig. INCOLOY alloy 803 nthuav tawm cov kev ntxhov siab-rupture zoo heev ntawm qhov kub siab. Cov yam ntxwv no, nrog rau kev ua haujlwm siab rau carburization thiab cyclic oxidation, ua rau INCOLOY alloy 803 cov khoom xaiv rau ntau daim ntawv thov hnyav xws li ID-finned pyrolysis tubing hauv high-severity ethylene furnaces.

Khoom Taw qhia

Incoloy Alloy 803 yeeb nkab yog ib qho kev ua haujlwm siab nickel hlau chromium alloy yeeb nkab nrog zoo corrosion kuj thiab zoo kub lub zog. Cov hlau no sib txuas cov kev tiv thaiv corrosion ntawm npib tsib xee nrog kev txhawb zog ntawm cov hlau thiab chromium, ua rau nws ruaj khov thiab ruaj khov hauv ntau qhov chaw hnyav.

Cov tshuaj muaj pes tsawg leeg ntawm Incoloy 803 yog tsim tshwj xeeb thiab muaj cov ntsiab lus siab ntawm nickel (kwv yees li 65%), nrog rau cov ntsiab lus tseem ceeb xws li chromium (kwv yees li 20%) thiab hlau (kwv yees li 12%). Qhov sib ntxiv ntawm chromium tsis tsuas yog txhim kho oxidation corrosion kuj ntawm cov hlau, tab sis kuj txhim kho nws cov corrosion kuj nyob rau hauv kev txo qhov chaw. Cov hlau kuj tseem muaj me me ntawm manganese, silicon, tooj liab thiab molybdenum, uas ua haujlwm ua ke los txhim kho cov khoom siv corrosion thiab cov khoom siv kho tshuab.

Incoloy 803 qhia tau hais tias zoo heev txhua yam khoom, xws li lub zog siab thiab zoo toughness, ob qho tib si nyob rau hauv chav tsev kub thiab kub. Qhov no tso cai rau nws siv nyob rau hauv tej yam kev mob ntawm withstanding loj stresses thiab complex loads, tshwj xeeb tshaj yog nws cov kev ua tau zoo nyob rau hauv high-temperature ib puag ncig yog nws salient feature. Piv txwv li, nyob rau hauv kev lag luam tshuaj, cov khoom siv kho cua sov thiab cov ntawv thov kev lag luam marine, Incoloy 803 cov kav dej tuaj yeem tiv taus thermal cycling thiab tshuaj corrosion, uas qhia txog kev ruaj ntseg thiab kev ntseeg tau ntev.
