Yintoni i-ASTM A501?

ASTM A501 intsimbiyityhubhu emnyama neshushu editshiweyo eyenziwe ngesinyithi eshushu-eyenziweyo edityanisiweyo kunye neseamless carbon steel structural tubhing ukulungiselela iibhulorho, izakhiwo, kunye nezinye iinjongo zolwakhiwo jikelele.

Ukuhlelwa kwamaBanga

I-ASTM A501 ihlelwe ngokwamabakala amathathu, iBakala A, iBakala B, neBakala C.

Iimilo zeCandelo eliHoli

Isikwere, ingqukuva, uxande, okanye iimilo ezikhethekileyo.

Iimpahla ezingekasilwa

Intsimbi iya kwenziwa ngesiseko-i-oksijeni okanye i-electric-arc-furnace-steel-making process.

Intsimbi inokuphoswa kwiingothi okanye iphoswe ngomsonto.

Iinkqubo Zokuvelisa

Ityhubhu iya kwenziwa ngenye yezi nkqubo zilandelayo:engenamthungo;i-furnace-butt-welding (i-welding eqhubekayo);ukuwelda ukumelana nombane (ERW)okanye i-arc welding ephantsi kwamanzi (i-SAW) ilandelwa ngokutshisa kwakhona kwi-cross-section kunye nokutshisa ukubunjwa ngokunciphisa okanye ukubunjwa kwenkqubo, okanye zombini.

Ukubunjwa kokugqibela kobume kuya kwenziwa ngenkqubo yokubumba eshushu.

Kuya kuvunyelwa ukongeza unyango oluqhelekileyo lobushushu kwityhubhu enobunzima bodonga olukhulu kune-13mm [1/2 in].

Ukwakhiwa kwemichiza ye-ASTM A501

Indlela yoVavanyo: ASTM A751.

astm a501 IiMfuno zeMichiza

Kwinqanaba le-ASTM A501, kukho iindlela ezimbini zokuhlalutya ukwakheka kweekhemikhali zensimbi: uhlalutyo lwe-thermal kunye nohlalutyo lwemveliso.

Uhlalutyo lwe-thermal lwenziwa ngexesha lokunyibilika kwentsimbi.Injongo yalo kukuqinisekisa ukuba ukubunjwa kweekhemikhali zensimbi kuhlangabezana neemfuno zomgangatho othile.

Uhlalutyo lwemveliso, ngakolunye uhlangothi, lwenziwa emva kokuba intsimbi sele yenziwe imveliso.Le ndlela yokuhlalutya isetyenziselwa ukuqinisekisa ukuba ukubunjwa kweekhemikhali zemveliso yokugqibela ihlangabezana neemfuno ezichaziweyo.

IiPropati zoomatshini ze-ASTM A501

Iindlela zovavanyo kunye neenkcazo zihambelana neemfuno ezifanelekileyo ze-ASTM A370.

astm a501_Tensile Iimfuno

Ubunzima beendonga ≤ 6.3mm [0.25in] ayifuni uvavanyo lwempembelelo.

Ukunyamezelwa komda kwe-ASTM A501

astm a501-Dimensional tolerances

Ukugalela

Ukuze iityhubhu zesakhiwo zibe shushu-dip zenziwe ngegalvanized, le ngubo iyakuhlangabezana neemfuno ze-Specification A53/A53M.

Ukulinganisa ixabiso lokugquma kumphezulu wangaphandle wombhobho ukumisela ubunzima bokugquma / ukutyeba.

Imbonakalo

Iityhubhu zesakhiwo aziyi kuba naziphene kwaye zibe nomphezulu ogudileyo ngexesha lokwenziwa kwe-hot rolling.

Iziphene zomphezulu ziya kuhlelwa ngolu hlobo xa ubunzulu besiphako somphezulu bungaphezulu kwe-10% yobukhulu bodonga oluqhelekileyo.

Iziphene ezifuna ukulungiswa ziya kupheliswa ngokupheleleyo ngokusika okanye ukugaya ngaphambi kwe-welding.

Ukumakisha

Ukumakishwa kwe-ASTM A501 kufuneka kube nale ngcaciso ilandelayo ubuncinane:

     Igama lomenzi

Uphawu okanye uphawu lwentengiso

Ubungakanani

Igama lomgangatho (unyaka wokupapashwa awufunwa)

IBanga

Ubude betyhubhu yolwakhiwo ngalunye kufuneka buphawulwe ngendlela efanelekileyo, njengokuqengqeleka, isitampu, isitampu, okanye ukupeyinta.

Kwimibhobho yesakhiwo <50 mm [2 kwi] OD, kuvumelekile ukuphawula ulwazi lwensimbi kwilebula efakwe kwi-bundle nganye.
