Yog vim li cas rau qhov sib txawv ntawm titanium txheej thiab gasket ntawm lub sealing nto ntawm lubtitaniumctus tubsteeltube uasheetyog raws li nram no: Ntawm ib sab, bolts tsis nruj raws li lub xeev kev khiav hauj lwm thaum cov khoom siv khiav, thiab cov bolts tseem nyob rau hauv lub pre-tightened lub xeev thaum cov khoom tsim. Lub zog nruj ntawm lub ntsej muag flange raug txo, thiab qhov sib txawv tshwm sim. Ntawm qhov tod tes, PTFE gasket xaiv los ntawm cov cuab yeej muaj qhov tshwm sim ntawm qhov txias txias ntawm chav tsev kub, uas tseem ua rau lub zog nruj ntawm cov flange qhov chaw kom txo qis thiab qhov khoob yuav tshwm sim. Tsis tas li ntawd, cov tshuaj fluoride ua los ntawm PTFE gasket yuav ua rau cov txheej txheem passivation ntawm cov khoom siv titanium thiab txhawb qhov tshwm sim ntawm crevice corrosion.
Kev ntsuas los kho qhov sealing nto ntawm daim ntawv titanium raj
1. Txhim kho qhov crevice corrosion kuj ntawm lub raj ntawv sealing nto
Raws li kev khiav hauj lwm ntawm cov khoom siv, titanium alloy nrog zoo dua crevice corrosion kuj yog xaiv raws li cov khoom siv los tiv thaiv corrosion thiab PTFE-coated asbestos gasket nrog elasticity zoo dua yog xaiv raws li lub foob.
2. Kev ntsuas kev saib xyuas xav txog tias titanium-steel phaj yog kim, thiab lub voj voog rov ua dua yog ntev, uas yuav ua rau poob loj, yog li cov yeeb nkab phaj yuav tsum tsis txhob muab pov tseg.
3. Cov ntsiab lus tseem ceeb ntawm vuam tswj ntawm lub nplhaib hauv ob sab phlu
Titanium yog ib qho khoom siv hlau. Nws sai sai reacts nrog oxygen, nitrogen, thiab hydrogen ntawm qhov kub thiab txias. Nws absorbs hydrogen sai tshaj 300 ° C, sai absorbs oxygen saum 600 ° C, thiab sai absorbs nitrogen saum 700 ° C. Thaum lub sij hawm welding, lub welded sib koom yuav tsum muaj kev tiv thaiv zoo, txwv tsis pub, nws yuav ua rau kev sib koom ua haujlwm txo qis, lossis txawm tias embrittlement.
Cov ncauj lus kom ntxaws txog kev siv vuam yog raws li hauv qab no
1) Qhov chaw vuam yog polished thiab ntxuav nrog acetone kom tshem tawm cov impurities xws li roj stains ntawm qhov chaw vuam thiab qhov chaw ntawm vuam hlau;
2) Teeb lub laj kab hauv qhov chaw vuam kom tiv thaiv ib puag ncig los ntawm kev tshuab thaum lub vuam txheej txheem. Lub tail gas trailing hood yog siv rau kev taug qab kev tiv thaiv thaum vuam, thiab thaj tsam ntawm cov welded sib koom siab tshaj 300 ℃ yog zoo tiv thaiv;
3) Sab hauv thiab sab nrauv ntawm lub nplhaib hauv ob sab phlu yog kho los ntawm qhov chaw vuam mus rau saum npoo ntawm lub phaj phaj. Lub sab nrauv yog welded ua ntej, thiab tom qab ntawd sab hauv ncig. Thaum lub sij hawm vuam txheej txheem, kev ntsuas xws li segmentation thiab hla welding yog saws los txo cov kev ntxhov siab welding. Weld ob txheej, qhov kub ntawm cov khaubncaws sab nraud povtseg yog tsawg dua 60 ℃;
4) Txoj kev faus hlau welding yog siv thaum vuam, thiab vuam hlau feem ntau ntawm cov cua sov ntawm argon arc vuam arc.
4. Kev tshuaj xyuas kev kho vuam
1) Tom qab vuam tiav lawm, cov cuab yeej raug tshem tawm, thiab lub tiaj tus sealing nto ntawm lub nplhaib hauv ob sab phlu yog tsim nyog raws li cov txheej txheem ua tiav ntawm cov ntawv raj.
2) Cov tsos thiab xim ntawm cov welds yuav tsum raug tshuaj xyuas, thiab cov xim ntawm cov welds thiab thaj chaw muaj kev kub ntxhov yuav tsum yog nyiaj dawb.
3) 100% kev soj ntsuam nkag mus yog nqa tawm ntawm qhov chaw ntawm qhov vuam.
4) Siv cov bolts txuas ntxiv thiab PTFE-coated asbestos gaskets, cov cuab yeej tsim nyog hauv kev ntsuas siab dua.
5) Cov cuab yeej siv tau rov siv dua thiab ua haujlwm rau ib nrab xyoo, thiab kev hloov hluav taws xob hloov pauv tau mus txog qhov tsim nyog, tsis muaj qhov tshwm sim, thiab kev ua haujlwm tau zoo.
