Butt welding flange yog ib hom yeeb nkab haum, uas yog hais txog lub flange nrog lub caj dab thiab ib puag ncig cov yeeb nkab hloov thiab txuas nrog cov yeeb nkab los ntawm taub qab vuam. Lub taub qab vuam flange tsis yooj yim rau deform, muaj kev sib khi zoo, thiab siv dav. Nws yog tsim rau cov kav dej uas muaj qhov hloov pauv loj hauv qhov siab lossis qhov kub thiab txias lossis cov kav dej uas muaj qhov kub thiab txias, qhov kub thiab txias. Qhov kom zoo dua yog tias cov lus hais yog pheej yig, thiab lub nominal siab tsis tshaj 2.5MPa; Nws kuj yog siv rau kev thauj mus los quotations Nyob rau hauv cov kav dej uas kim, flammable thiab explosive media, lub nominal siab nyob ib ncig ntawm PN16MPa.
Qhov tseeb installation ib ntus ntawm taub qab vuam flange:
1. Ua ntej, sab hauv thiab sab nraud ntawm kev sib txuas stainless hlau yeeb nkab fittings yuav tsum tau txheeb xyuas ua ntej txuas pob tw vuam flanges.
2. Nruab cov flanges nrog grooved rings ntawm cov kav dej uas yuav tsum tau txuas nrog.
3. Qhov chaw nres nkoj ntawm cov yeeb nkab yuav tsum tau kho nrog 90-degree flanging txheej txheem. Tom qab kev kho mob, lub dav hlau ntawm qhov chaw nres nkoj ntawm cov yeeb nkab yuav tsum yog hauv av. Tom qab kev sib tsoo, nws yuav tsum yog ntsug thiab tiaj tus, thiab tsis muaj kev tsis ntseeg txog burrs, pob thiab deformation, thiab lub nozzle yuav tsum tau muab sib npaug nrog cov cuab yeej tshwj xeeb. .
4. Lwm txoj hauv kev yooj yim yog siv cov khoom tiav rau flange cov yeeb nkab luv thiab tom qab ntawd txuas rau ntawm cov yeeb nkab.
5. Embed stainless hlau sealing nplhaib ntawm O-shaped roj hmab sealing nplhaib ntsia rau ntawm ob sab hauv flange nrog zawj nplhaib. Lub puab qhov ntawm lub nplhaib sealing yog tib yam li lub puab txoj kab uas hla ntawm cov yeeb nkab.
6. Tom qab ntawd txuas cov flange qhov nrog bolts, thiab cov ntsia liaj qhov rooj cov khoom yuav tsum tau nruj nreem symmetrically.
7. Thaum zawm lub taub qab vuam flange, yuav tsum tau them nyiaj mloog kom paub meej tias qhov nruj ntawm txhua qhov sib koom ua ke yuav tsum ncav cuag qhov xav tau tshwj xeeb.
