BS EN 10210-1 2006 Cov Qauv Kub Zoo tiav Hollow Sections

Cov European Standard EN 10210-1: 2006 muaj qhov xwm txheej ntawm Cov Qauv British. Ntu no cov European Standard qhia txog cov khoom xa tawm cov khoom rau kub hollow lawmntu ntawm cov xwm txheej, square,cov duab plaub lossis cov duab elliptical thiab siv rau cov qhov khoob hauv cov duab tsim,

nrog lossis tsis muaj kev kho cua sov, lossis tsim khaub thuas nrogkev kho kub tom qab kom tau txais cov sib npaug ntawm cov xim hlau sib luag rau cov uas tau txais hauv cov khoom kub tsim.

1.Kev faib tawm thiab kev kos npe

⑴Kev faib tawm

①Nyob rau hauv cov qib muaj zog ntawm cov hlau tsis muaj hlau uas tau muab rau hauv Cov Lus Qhia A, plaub zoo qauv JR, J0, J 2 thiab K 2 tau teev tseg. Cov no sib txawv raws li qhov yuav tsum tau ua, txoj kevdeoxidation, txwv ntawm cov nuj nqis ntawm ntau yam, nrog rau kev siv rau leej faj thiab phosphorus, thiab kev tshuaj ntsuam thiab kuaj.

Ua raws li kev faib tawm nyob rau hauv EN 10020, txhua qib steel hauv Annex yog cov hlau tsis zoo.

②Tsis pub dhau lub zog qib ntawm cov hmoov nplej zoo muab rau hauv Annex B, ob qho zoo N thiab NL tau hais tseg. Cov no sib txawv nyob rau hauv kev sib hwm ntawm cov pa roj carbon, sulfur thiab phosphorus cov ntsiab lus, thiab tsis kub muaj kev cuam tshuam cov khoom.

Raws li kev faib tawm cov kab ke nyob rau hauv EN 10020, qib steel S 275 NH, S 275 NLH, S 355 NH thiab S 355 NLH tsis yog- alloy zoo hlau thiab qib steel S 420 NH, S 420 NLH, S 460 NH thiab S 460 NLH yog cov hlau tshwj xeeb.

2.Tsim Kom Muaj

⑴Rau cov tsis-alloy steel hollow tshooj cov qauv hlau muaj xws li:

①Tnws tus naj npawb ntawm Cov Qauv European no (EN 10210-1); tsab ntawv peev S rau cov qauv hlau;

②Tnws hais txog qhov tsawg kawg nkaus tau tawm los muaj zog rau lub thicknesses ≤ 16 mm qhia hauv MPa 1;

③Tnws cov peev tsiaj ntawv JR rau cov khoom zoo nrog cov kev cai cuam tshuam rau ntawm thaj chaw sov;

④Tnws cim J0 rau cov kev ua tau zoo nrog cov kev cuam tshuam ntawm kev cuam tshuam nyob rau hauv 0 ° C thiab cov cim J 2 lossis K 2 rau qhov zoo nrog cov khoom muaj feem cuam tshuam ntawm -20 ° C;

⑤Tnws peev H tus cim H qhia ntu hollow seem.

⑵Kev nplua zoo lis steel yam ntxwv ua ntu ua haujlwm cov qauv siv hlau ua muaj: 

① Number ntawm no Cov Qauv European (EN 10210-1);

② Capital tsab ntawv S rau cov qauv hlau;

③ Indication ntawm qhov tsawg kawg nkaus teev tawm los lub zog rau thicknesses

≤ {16 mm qhia hauv MPA;

④ Capital tsab ntawv N qhia txog kev ua haujlwm ib txwm lossis ib txwm sib sau (saib 6. 4);

⑤ Capital tsab ntawv L rau qhov zoo nrog cov kev cuam tshuam cuam tshuam ntawm - 50 ° C;

⑥ Capital tsab ntawv H qhia ntu hollow seem.
