Hongu, EN 10210 =BS EN 10210.
TS EN 10210 uye EN 10210 zvakafanana mune zvehunyanzvi zvemukati uye zvese zvinomiririra zviyero zveEurope zvekugadzira, kugadzira, uye zvinodiwa zvezvikamu zve thermoformed structural hollow.
BS EN 10210 ndiyo vhezheni yakagamuchirwa muUK, nepo EN 10210 iri chiyero cheEuropean-wide.Masangano akasiyana epasirese epasi anogona kutanga mwero nemapfupikiso emunyika, asi musimboti weiyo mwero unoramba uripo.
Hollow zvikamu zvinogona kuiswa muzvikamu sedenderedzwa, sikweya kana rectangular, kana elliptical.
Zvakare nekuti iri kupisa rakapedzwa maitiro zvinoenderana neEN 10210, inotevera chidimbu inogona kushandiswa.
HFCHS= inopisa yakapera denderedzwa hollow zvikamu;
HFRHS= inopisa yapera sikweya kana rectangular hollow zvikamu;
HFEHS= inopisa yakapera elliptical hollow zvikamu.
Round: Outer dhayamita kusvika 2500 mm;
Wall ukobvu kusvika 120 mm.
Ehe, hapana nzira yekugadzira machubhu ehukuru uhu uye ukobvu hwemadziro kana ERW welding process ikashandiswa.
ERW inogona kugadzira machubhu anosvika 660mm ane mudhuri ukobvu hwe20mm.
Simbi inogona kugadzirwa kana kuburikidza neaisina musono kana weldingprocess.
Pakati pewelding process, nzira dzakajairwa welding dzinosanganisiraERW(electric resistance welding) uyeSAW(yakanyura arc welding).
Pakati pezvimwe,ERWinyanzvi yewelding inobatanidza nhengo dzesimbi pamwe chete nenzira yekudzivirira kupisa uye kumanikidza.Iyi tekinoroji inoshanda kune akasiyana siyana ezvishandiso uye ukobvu uye inogonesa inobudirira welding process.
SAW, kune rumwe rutivi, inzira yewelding inoshandisa granular flux kuvhara arc, iyo inopa kupinza kwakadzika uye nani weld quality uye inonyanya kukodzera kune welding mahwendefa akakora.
Tevere, inzira yeERW, inova nzira yekugadzira ine hunyanzvi inoshandiswa zvakanyanya kugadzira machubhu akasiyana siyana esimbi nemaprofile.
Izvo zvinofanirwa kucherechedzwa kuti kune isina alloyed uye yakanaka-zviyo makomba zvikamu zvinogadzirwa newelding process, kugadzirisa welds hazvibvumidzwe kunze kwekunyudzwa kwearc welding.

Iko kusimba kwegoho shoma reS355J2H simbi pombi haina kugadzikiswa, inoshanduka neyakasiyana madziro ukobvu.
Kunyanya, simba regoho reS355J2H rakagadzirirwa maererano nechiyero apo rusvingo rwemadziro rushoma kudarika kana kuenzana ne16mm, asi kana rusvingo runowedzera, simba regoho richaderedzwa, saka kwete yose S355J2H simbi pombi inogona kusvika zvishoma. simba re355MPa.
