Hauv Tebchaws Europe txoj kev lag luam uas tau tsim kho thiab tswj hwm zoo heev, kev ua tau zoo, kev ntseeg siab, thiab kev ua raws li cov ntaub ntawv yog qhov tseem ceeb heev. Ntawm ntau cov ntaub ntawv tseem ceeb, EN 10216 S355J2H seamless steel tube, uas paub txog nws cov khoom zoo heev, tau dhau los ua qhov kev xaiv zoo hauv ntau lub lag luam tseem ceeb, los ntawm kev siv hluav taws xob mus rau kev tsim khoom siv hnyav. Tsab xov xwm no tshawb nrhiav cov yam ntxwv ntawm cov hlau no, cov qauv uas nws ua raws, thiab nws cov ntawv thov dav dav hauv kev lag luam European.

Nkag Siab Txog Tus Txheej Txheem thiab Cov Khoom Siv: EN 10216 thiab S355J2H

Ua ntej, nws yog ib qho tseem ceeb kom txhais lub ntsiab lus tom qab nws lub npe:

•EN 10216: Qhov no yog cov qauv txheej txheem European uas qhia meej txog cov xwm txheej kev xa khoom rau cov kav hlau tsis muaj qhov tsis sib xws rau lub hom phiaj siab. Cov qauv txheej txheem no ua kom cov kav hlau tswj tau lawv cov khoom siv kho tshuab ntawm qhov kub siab, ua rau lawv haum rau cov khoom siv siab. Cov qauv tshiab tshaj plaws tau hloov los ntawm cov khoom xws li EN 10216-1 thiab EN 10216-2, tab sis qib S355J2H thiab nws cov kev xav tau tau raug nqa mus tom ntej.

•S355J2H:

◦S: Sawv cev rau "Cov Hlau Qauv".

◦355: Qhia txog qhov tsawg kawg nkaus ntawm 355 Megapascals ntawm chav tsev kub, txhais tau tias nws muaj kev tiv thaiv zoo heev rau kev hloov pauv thiab lub peev xwm thauj khoom.

◦J2: Sawv cev rau qib Impact Toughness. Nws qhia tau tias qhov kev sim Charpy V-notch impact tau ua tiav ntawm -20°C thiab ua tau raws li qhov yuav tsum tau nqus hluav taws xob tshwj xeeb. Qhov no ua kom cov khoom siv tiv taus kev tawg yooj yim txawm tias nyob hauv qhov chaw txias, tseem ceeb rau kev teeb tsa sab nraum zoov hauv thaj chaw xws li Northern Europe.

◦H: Sawv cev rau "Normalized Condition". Qhov no txhais tau tias lub raj hlau tau dhau los ntawm kev kho cua sov kom zoo dua qub los txhim kho cov qauv noob, txhim kho cov qauv me me, thiab yog li txhim kho nws cov khoom siv kho tshuab thiab kev tawv, ua rau nws sib xws thiab ruaj khov dua.

Hauv kev xaus lus, EN 10216 S355J2H yog lub raj hlau tsis muaj qhov tsis sib xws nrog lub zog siab, zoo heev rau qhov kub thiab txias qis, thiab kev ntseeg tau, tsim tshwj xeeb rau qhov chaw siab thiab muaj kev ntxhov siab.

Cov Cheeb Tsam Tseem Ceeb hauv Kev Lag Luam European

Cov khoom ntawm S355J2H seamless raj ua rau lawv zoo tagnrho rau cov kev xav tau siab rau kev nyab xeeb, kev ua haujlwm zoo, thiab kev ruaj khov hauv kev lag luam European. Lawv cov chaw siv tseem ceeb suav nrog:
