Kev Piav Qhia Luv:

2205 Duplex Stainless Steel Tubes. Ib hom hlau duplex uas siv dav dav uas muaj zog thiab tiv taus xeb hauv ntau yam organic acids, anorganic acids, dej txias thiab hydrous H2S/NaCl sib xyaw. Nrog rau qhov sib xyaw ze ntawm austenite thiab ferrite, lawv muab lub zog tso zis siab dua 30% thiab lub zog tensile siab dua li cov austenitics uas muaj nitrogen. Muaj kev tiv taus xeb dav dav thiab tshwj xeeb tshaj yog rau pitting thiab crevice corrosion. Lawv txoj kev tiv taus kev ntxhov siab-xeb tawg hauv cov chlorides tsis muaj zog zoo dua li cov austenitics. Hauv cov chaw muaj chloride acidic lossis nruab nrab qaub uas muaj hydrogen lossis sulphide kev ntxhov siab tawg ntau dua, yuav tsum xav txog cov alloyed austenitics siab dua. Cov nqi cuam tshuam siab thiab qhov kub hloov pauv ntawm cov ntaub ntawv puag ncig sib txawv ntawm - 50 ° C. Txawm li cas los xij, qhov sib piv thiab kev taw qhia ntawm ferrite hauv cov vuam thiab cov ntaub ntawv puag ncig yuav cuam tshuam rau qhov tawv ntawm qhov kub qis dua xoom. Kev raug rau qhov kub nruab nrab thiab siab thiab txias tsawg dua yuav ua rau embrittlement.
