Txoj kev sib txuas ntawm taub qab vuam flange thiab tiaj vuam flange yog txawv:

Txoj kev sib txuas ntawm taub qab vuam flange thiab tiaj vuam flange yog txawv:

Qhov loj tshaj qhov sib txawv ntawm cov qauv ntawm lub caj dab tiaj tus flanges thiab pob tw-welded flanges nrog caj dab yog nyob rau hauv kev sib txuas ntawm cov yeeb nkab thiab flange. Lub tiaj-welded flanges nrog caj dab feem ntau txuas nrog lub flange los ntawm lub kaum pob qij txha, thiab lub caj dab pob tw welding Lub flange yog lub pob tw ntawm lub flange thiab cov yeeb nkab.

Lub nominal siab ntawm caj dab ca vuam flange yog: {{0}}}6---4.0MPa, thaum lub nominal siab ntawm caj dab caj dab vuam flange yog: 1--25MPa qib. Obviously, qhov hloov tau siab theem ntawm necked ca vuam flange yog zoo dua li qis.

Cov khoom siv ntawm caj dab ca vuam flange yog machined los ntawm cov hlau zoo tib yam nrog lub thickness yuav tsum tau, thaum cov khoom ntawm necked pob tw vuam flange feem ntau machined ntawm forged steel.

Butt welding flanges thiab tiaj vuam flanges muaj cov ntaub ntawv sib txawv

Kev tshuaj xyuas hluav taws xob tsis muaj rau cov welded seams, tab sis rau pob tw welded seams. Lub weld daim ntawv ntawm cov yeeb nkab thiab lub flange ntawm lub caj dab tiaj tus welded flange yog ib tug fillet weld, thaum lub weld daim ntawv ntawm lub caj dab pob tw welded flange thiab cov yeeb nkab yog ib tug girth weld; Lub tiaj weld yog ob fillet girth welds, Butt weld yog pob tw girth weld. Qhov sib txawv ntawm lub tiaj-welded flanges nrog caj dab thiab tiaj-welded flanges tsis muaj caj dab yog tias tiaj-welded flanges nrog caj dab muaj ib qho chaw ntxiv rau hauv cov kav dej welding txoj hauj lwm dua li lub tiaj-welded flanges tsis muaj caj dab. Lub flange kuj yog ib qho flange tiaj tus, thiab tus thawj coj tsis muaj flange kuj yog ib lub tiaj tiaj tiaj. Qhov sib txuas ntawm lub caj dab taub qab-welded flange thiab cov yeeb nkab txuas yog nyob rau hauv hom B seam, thiab qhov sib txuas ntawm lub caj dab ca-welded flange thiab cov yeeb nkab txuas yog hom C seam, thiab qhov kev sim tsis muaj kev puas tsuaj tom qab vuam sib txawv.
