Stainless hlau flange yog flange uas txuas cov kav hlau, fittings, thiab lwm yam rau hauv lub flange thiab txuas rau cov khoom siv lossis cov kav dej los ntawm cov welds. Lub puab qhov ntawm ib sab ntawm lub flange yog nruab nrog ib tug welding protrusion, thiab welding protrusion muaj ib tug puab qhov. Lub puab lub qhov txuas nrog lub puab qhov ntawm qhov nruab nrab ntawm lub flange, thiab muaj elasticity ntawm lub flange thiab tus thawj vuam. Ob sab saum toj ntawm lub nplhaib elastic yog txuas nrog lub flange thiab tus thawj vuam. Muaj ntau lub qhov taub ntawm lub flange. Cov ntsia hlau qhov yog symmetrically faib nyob ib ncig ntawm qhov chaw ntawm lub flange. Stainless hlau flanges yog ua los ntawm stainless hlau, ua raws li polyethylene yas txheej, roj hmab txheej, thiab PVC txheej. Tom ntej no, cia peb saib cov kev ceev faj rau kev siv stainless hlau flanges.
1. Txhawm rau tiv thaiv corrosion ntawm lub qhov muag ntawm stainless hlau flanges tshwm sim los ntawm cua sov, vuam tam sim no yuav tsum tsis txhob siab dhau heev lawm, li ntawm 20% tsawg tshaj li ntawm cov pa roj carbon steel welding rods, lub arc yuav tsum tsis txhob ntev dhau lawm, qhov txias txias yuav tsum yog. nruab nrab ntawm cov khaubncaws sab nraud povtseg, thiab qhov nqaim weld nyhuv zoo dua.
2. Cov electrode yuav tsum tau muab cia kom qhuav thaum siv. Perovskite hom yuav tsum tau ziab ntawm 150 degree rau 1 teev, thaum uas tsis tshua muaj hydrogen hom yuav tsum kom qhuav ntawm 200-250 degree rau 1 teev (tsis txhob rov ua kom qhuav ntau zaus, txwv tsis pub cov txheej yuav ua rau tawg thiab tev tawm) kom tsis txhob muaj kab mob xws li roj stains ntawm lub electrode txheej, uas yuav ua rau kom cov pa roj carbon ntsiab lus ntawm weld thiab cuam tshuam qhov zoo ntawm weld.
3. Thaum vuam stainless hlau flange fittings, rov ua cua sov yuav precipitate carbides, txo lawv corrosion kuj thiab txhua yam khoom.
4. Chromium stainless hlau flange fittings nrog siab hardenability tom qab vuam yog feem ntau tawg nyob rau hauv American standard flanges. Yog tias tib lub chromium stainless hlau vuam pas nrig yog siv rau vuam, nws yuav tsum tau preheat yam tsawg 300 degree tom qab vuam thiab txias maj mam nyob ib ncig ntawm 700 degree. Yog tias cov khoom siv welded tsis tuaj yeem raug kho tom qab vuam kub, stainless hlau flange yeeb nkab vuam rods yuav tsum tau siv.
5. Rau stainless hlau flanges, ntxiv qhov tsim nyog stabilizing ntsiab xws li Ti, Nb, Mo, thiab lwm yam los txhim kho corrosion kuj thiab weldability. Weldability yog superior rau chromium stainless hlau flanges. Thaum siv tib hom chromium stainless hlau flange vuam pas nrig, nws yuav tsum tau preheated rau ntau tshaj 200 degree thiab tempered ntawm ib ncig ntawm 800 degree tom qab vuam. Yog tias cov khoom siv welded tsis tuaj yeem raug kho cua sov, stainless hlau flange yeeb nkab vuam rods yuav tsum tau siv.
6. Stainless hlau flange fittings thiab pob tw welded flange electrodes muaj corrosion kuj zoo thiab oxidation tsis kam, thiab yog dav siv nyob rau hauv tshuaj, chiv, roj av, thiab kev kho mob machinery manufacturing.
