Yiziphi izinhloso zomkhiqizo we HE wezigaba zase-Europe zoH-shaped steel?

Njengoba yindlela ebalulekileyo yokubandakanya ekuhlaleni nokungeni, ukuhwekwa nokukhetha izimaterialo ye-HE series ye-H-shaped steel ngokwesivikeli esiyinhlanganisela kumele kwenziwe ngokucophelela ukuthuthukisa nokuthuthukisa kwezimali zokungeni. Le ngeke yindlela encane yokuhwekwa nokukhetha izimaterialo ze-HE series ye-H-shaped steel ngokwesivikeli esiyinhlanganisela:

1. Ukuhwekwa kwe-HE series ye-H-shaped steel ngokwesivikeli esiyinhlanganisela

I-H-shaped steel ngokwesivikeli esiyinhlanganisela i-HE series ibantshela ngokuphelele imodeli efanayo ne-HEA, HEB, kunye ne-HEM, nganye inobuninzi besisigqibo ukulandelana nezidingo zokungeni ezahlukana. Oku kuyilokhu:

Uhlobo lwe-HEA: Le yindlela encinci yamandla e-H edlule ngokwezimali ezincinci kakhulu neyindlela encinci yokubeka kanye nokuthuthwa kwayo. Kusetshenziswa kakhulu ngokwezimali nezinkundla zokuvamisa izindlu nezindlela zokugcina, kudingeka kakhulu ukuthuthwa kwezimali ezinkulu nezindlela ezilayishwa. Izinhlobo zase-HEA zilandela lezi: HEA100, HEA120, HEA140, HEA160, HEA180, HEA200, HEA220, njll., nganye enenye yazo inezimali ezifanayo nezindlela ezilayishwa.

Uhlobo lwe-HEB: Le yindlela edlule yamandla e-H edlule ngokwezimali ezincinci kakhulu kune yase-HEA, neyindlela encinci yokubeka kanye nokuthuthwa kwayo. Kusetshenziswa kakhulu ngokwezimali nezindlela zokuvamisa izindlu nezindlela zokugcina, kudingeka ukuthuthwa okuphezulu kwezimali. Izinhlobo zase-HEB zilandela lezi: HEB100, HEB120, HEB140, HEB160, HEB180, HEB200, HEB220, njll.

Uhlobo lwe-HEM: Leli ni-steel ephambene ne-H edlulelwe ngemaphakathi amawide-flange, nezwele eziphambene kakhulu nazo ezikwiwo HEB, nangaphezulu amadimetshoni namanani. Kufaneleke kwezindlela zokuvumela nezindlela zokwenza izinkampani ezidinga ukuthola kakhulu. Noma ukuthi amamodeli wokwehla we-HEM series akuchazwanga kulesi sivakalisi, amakhubalo walo njengento ye-steel wide-flange yenza lapho kusebenza kakhulu kwezindlela zokuvumela nezindlela zokwenza izinkampani.

Kudingeka futhi, izinhlobo zika-HEB-1 ne-HEM-1 zi-versheni ezimprove zika-HEB ne-HEM, nangaphezulu amadimetshoni namanani wokuthola ukuthola kakhulu. Kufaneleke kwezindlela zokuvumela nezindlela zokwenza izinkampani ezidinga ukuthola kakhulu.

2. Izindawo zokuvumela H-Beam HE Series lestanda ye-Europe

I-Eropey Standard H-Beam HE series ngokuvumelekileya isebenta lesteel ye-alloy encane ukusebenza ngokuhle fanye nokuba yilapho elinekati elide. Lezi zithiwe zinobukhosi bendawo kanye nobungqina obuningi, bengakhi futhi ukwakhiwa okuhambisanayo. Izithiwe zinhlobo ezifanayo S235JR, S275JR, S355JR, kanye S355J2, kanye namanye. Lezi zithiwe ziyavumelana neStandanda ye-Erope EN 10034 fanye wokuthola ukwamiswa kwe-EU CE.
