Q235B SSAW Pipe

Q235B kauv welded yeeb nkab yog ib hom carbon structural steel yeeb nkab nrog lub zog tawm los (σs) ntawm 235 MPa. Nws yog tsim los ntawm coiling low-carbon carbon structural steel strips ntawm ib lub kaum ntse ntse (hu ua lub kaum sab xis) los tsim cov yeeb nkab blanks, thiab ces welding cov yeeb nkab seams ua ke. Q235B kauv welded yeeb nkab yog ib hom thiab nrov ntawm welded yeeb nkab.

GNEE Q235B Welded Yeeb Nkab Vuam Requirements thiab Txheej Txheem Parameters

Weld Seam Qhov siab tsawg dua 1.6 hli, hauv zos tsis tshaj 2.5 hli, thiab nrog qhov ntev tsis ntau tshaj 50 hli; interlayer kub tsis qis dua 100 degree. Nyob rau hauv cov ntaub ntawv ntawm overlayer kub, nws yuav tsum tau tso cai rau ib txwm txias mus rau lub teev kub. Hauv paus vuam ib puag ncig cua ceev tsawg dua 2.0 m / s, sau thiab capping vuam ib puag ncig cua ceev tsawg dua 5 m / s, ambient kub 28-29 degree, huab cua txheeb ze av noo 65%-70%.

Ua ntej vuam, qhov chaw yuav tsum tau welded yuav tsum tau muab ntxuav kom huv si kom paub tseeb tias tsis muaj roj, xeb, oxide txheej, los yog lwm yam kab mob. Qhov ntev ntawm qhov chaw vuam yuav tsum tswj nyob rau hauv qhov ntau ntawm 10-20 hli.

Vuam tsis muaj xws li vuam zawj kev npaj, vuam cov khoom qauv specifications, tam sim no polarity, vuam tam sim no, arc voltage, xaim pub ceev, vuam ceev, thiab tshav kub input raws li pWPS.

Tom qab qhov kev xeem phaj vuam tiav lawm, kev kuaj pom thiab tsis muaj kev puas tsuaj yuav tsum tau ua raws li cov qauv kom tau raws li qhov yuav tsum tau muaj ntawm NB / T 47014 thiab lwm cov qauv kev lag luam.

Mechanical zog muaj xws li tensile, low-temperature impact, hardness, and bending tests. Cov txiaj ntsig kev xeem yuav tsum ua kom tau raws li qhov yuav tsum tau ua ntawm cov qauv kev soj ntsuam lossis cov khoom lees paub tshwj xeeb, thiab qhov ntau ntawm kev tshuaj xyuas qhov tsis zoo macroscopic yuav tsum ua raws li ntau yam tau teev tseg hauv cov qauv ntsuas.
