Flange los ua haujlwm txij nkawm ntawm cov yeeb nkab fittings

Hauv kev tsim khoom, lub qhov (socket fittings) tuaj yeem ua los ntawm cov khoom siv sib txawv, thiab cov qauv sib txawv thiab cov qauv ntawm lub qhov (socket fittings) tau siv ntau zaus. Nws yuav tsum tau siv raws li nws cov yam ntxwv, thiab lub qhov (socket) fittings khaws cia rau lub sijhawm ntev yuav tsum tau siv ntau zaus. Txheeb xyuas tias cov khoom raug sab nraud ntev ntev yuav tsum tau ntxuav kom huv si kom tshem tawm qee qhov av, thiab tom qab ntawd muab tso rau hauv chav dav dav thiab qhov cua. Tsis txhob muab lawv ua ke, tsis txhob khaws cia rau hauv qhov chaw qhib, thiab muab tso rau hauv qhov chaw qhuav thiab qhov cua. Khaws raws li qhov xav tau.

Flange socket yeeb nkab fittings yog tsim los ntawm ntau cov ntaub ntawv

Lub luj tshib ntawm lub qhov (socket) yeeb nkab haum yog txawv ntawm lub luj tshib ntawm lwm yam khoom. Qee cov tshuaj nyob rau hauv nws yuav tiv thaiv qhov saum npoo ntawm lub luj tshib los ntawm xeb mus ntev thiab nws tsis yooj yim rau corroded. Muaj ntau yam khoom siv, xws li carbon steel. , Alloy steel, thiab lwm yam., tus nqi ntawm lub qhov (socket) yeeb nkab fittings yog pheej yig heev, qhov ntau siv yog loj, thiab kev siv cov hlau alloy steel luj tshib yog txwv.

Taw qhia txog kev ua tau zoo ntawm stainless hlau flange

Stainless hlau flanges muaj hlau zoo thiab muaj zog corrosion kuj. Lawv feem ntau siv hauv cov qauv hlau, xws li stainless hlau flanges. Stainless hlau flanges kuj ua stainless acid-resistant steel flanges, thiab lawv cov hlau nto yog du. , Nws tsis yooj yim rau oxidize nrog huab cua, yog li nws yog feem ntau siv nyob rau hauv high-pressure dej kav thiab corrosive siab kav. Ntawm no, kuv yuav qhia rau koj txog kev ua tau zoo ntawm stainless hlau flanges.

Ua ntej, raws li cov khoom siv hlau, nws yuav hnov ​​​​mob nrog huab cua hauv qhov chaw ntub dej, yog li hloov cov khoom qub hlau, tab sis stainless hlau flange tuaj yeem cuam tshuam nrog cov oxidant, tsim cov tawv thiab ntom chromium-nplua nuj oxide tiv thaiv zaj duab xis ntawm qhov chaw. Cr2O3, stainless hlau flange zoo tiv thaiv ntxiv cov tshuaj tiv thaiv oxidation. Lwm cov kav dej hlau, xws li cov kav dej galvanized thiab cov kav dej tooj liab, muaj peev xwm ua kom tsawg. Qhov no yog qhov laj thawj tseem ceeb vim li cas qhov kev tiv thaiv corrosion ntawm cov kav dej galvanized yog tsawg dua li ntawm cov kav hlau stainless.

Tom qab ntawd qhov kev ua haujlwm corrosion kuj ntawm stainless hlau flanges, stainless hlau flanges yuav tsis zoo ib yam li carbon steel, thiab tsis muaj kev tiv thaiv txheej thaum siv; stainless hlau flanges siv stainless hlau flanged dej kav, thiab tsis muaj kev txwv rau cov tshuaj muaj pes tsawg leeg ntawm cov dej, vim stainless hlau yog cov dej uas muaj cov ntsiab lus oxygen, kub, PH thiab hardness muaj corrosion kuj zoo; Cov kav dej stainless hlau tuaj yeem tiv taus tus nqi ntws siab heev, txawm tias tus nqi ntws ntau dua 40 m / s, nws tseem tuav tus nqi qis heev, tsis tshaj 0.003 mm / Nws yog qhov tshwj xeeb tshaj yog haum rau high- nce dej. Lub coefficient ntawm thermal expansion ntawm stainless hlau flange kav yog zoo ib yam li cov tooj liab kav, uas yog 1.5 npaug ntawm zoo tib yam steel kav. Piv nrog stainless hlau flanges, stainless hlau flange kav muaj cov yam ntxwv ntawm qeeb thermal expansion thiab qeeb contraction.

Tsis tas li ntawd, cov tshuaj tiv thaiv ntawm stainless hlau flanges feem ntau yog ib qho tseem ceeb, thiab cov yeeb yaj kiab tiv thaiv yuav raug tsim rau saum npoo, uas yog tsis yooj yim sua rau lwm yam hlau.
