Stainless hlau flanges yog disc - Daim duab puab, feem ntau siv hauv kev tsim kho pipeline. Lawv feem ntau yog siv ua khub. Hauv kev tsim kho pipeline, stainless hlau flanges yog feem ntau siv rau kev txuas kav dej.
Rau kev sib txuas kav dej, ib flange yog ntsia. Tsawg -} Cov kav hlau siv tuaj yeem siv xov uas tsis muaj zog, thaum kav cov dej siab sib xyaw saum 4 KG siv Welded Flanges.
Lub gasket tso rau ntawm ob lub pluaj, thiab tom qab ntawd bolted ruaj ntseg. Flanges rau cov kev cai sib txawv muaj cov thickinges sib txawv thiab yuav tsum muaj cov tw sib txawv.
Ceev faj rau kev siv cov hlau Stainless Flanges:
1. Txhawm rau tiv thaiv kev txhim kho kev txhim kho los ntawm cov cua sov ntawm lub ntsej muag flange, kwv yees li 20% qis dua uas siv nrog cov roj carbon standodes. ARC yuav tsum tsis ntev ntev, thiab kev sib tshuam yuav tsum nrawm. Nqaim welds yog nyiam.
2. Vuam cov pas nrig yuav tsum tau khaws cia kom qhuav thaum siv. Titanium - Calcium hom yuav tsum tau qhuav ntawm 150 {{{}} ib qho hydrogen hom yuav tsum tau qhuav ntawm 200-250℃rau ib teev. (Tsis txhob muab ntau dua, vim qhov no yuav ua rau cov txheej txheej tawg thiab roj av.) Zam kom muaj cov roj ntsha thiab lwm yam paug ntawm cov ntsiab lus carbon thiab lwm yam.
3. Thaum vuam stainless hlau flanges thiab cov yeeb nkab fittings thiab cov cua sov dua tuaj yeem tso cov carbides, txo cov khoom lag luam tiv thaiv thiab cov khoom siv tshuab.
4. Chromium Stainless Hlau Flanges thiab cov yeeb nkab fittings muaj cov tshaj tawm siab dua {} Weld hardening tus nqi dua li American txheem flanges thiab muaj ntau dua kev tawg. Yog tias siv cov chromium zoo li chromium stainless hlau electrodes (G202, G207), preheating saum 300 tawm kom txias rau kwv yees li ntawm 700 qeeb tom qab vuam yog qhov tseem ceeb. Yog tias tshaj tawm - Weld kev kho cua sov tsis tau rau cov weldment, stainless hlau Flange electrodes (A107, A207) yuav tsum tau siv.
5. Stainless hlau flanges tau txhim kho corrosion tsis zoo thiab weldability los ntawm kev ntxiv cov khoom ruaj khov xws li Ti, NB, thiab Mo. Lawv lub vias zoo dua li ntawm chromium stainless hlau flanges.
Thaum siv cov chromium zoo ib yam stainless hlau Flange Vuam Rods (G307), preheating rau saum toj kawg 200 degree} Yog tias kev kho cua sov tsis tau rau kev siv hluav taws xob, stainless hlau flange thiab yeeb nkab welding rods (A107, A207) yuav tsum tau siv.
6. Stainless hlau Flange thiab yeeb nkab Welding Rods muaj cov tshuaj corrosion zoo nkauj, chiv, roj av, thiab kev lag luam machinery kev lag luam.
