Gulu B ndi Gulu C ndi magiredi awiri osiyana pansi pa ASTM A500 standard.
ASTM A500ndi muyeso wopangidwa ndi ASTM International wozizira wopangidwa ndi welded komanso wopanda mpweya wa carbon steel structural chubing.
Kenako, tiyeni tifanizire ndi kuwasiyanitsa m’njira zosiyanasiyana kuti timvetsetse kufanana kwawo ndi kusiyana kwawo.
Kusiyana
ASTM A500 Gulu B ndi C zimasiyana kwambiri pamapangidwe amankhwala, mawonekedwe olimba, komanso malo ogwiritsira ntchito.
Kusiyana kwa Chemical Composition
Muyeso ya ASTM A500, pali njira ziwiri zowunikira momwe chitsulo chimapangidwira: kusanthula kwamafuta ndi kusanthula kwazinthu.
Kusanthula kwamafuta kumachitika panthawi yosungunuka kwachitsulo.Cholinga chake ndi kuonetsetsa kuti mankhwala a zitsulo amakwaniritsa zofunikira za muyezo wapadera.
Kusanthula kwazinthu, kumbali ina, kumachitidwa pambuyo poti zitsulo zapangidwa kale kukhala mankhwala.Njira yowunikirayi imagwiritsidwa ntchito kutsimikizira kuti mankhwala opangidwa ndi mankhwala omaliza amakwaniritsa zofunikira.
Nzosadabwitsa kuti mpweya wa kalasi C ndi wotsika pang'ono kusiyana ndi wa Giredi B, zomwe zingatanthauze kuti Gulu C limakhala lolimba kwambiri powotcherera ndi kuumba.
Kusiyana kwa Tensile Properties
Gulu B: Nthawi zambiri imakhala ndi ductility yayikulu, yomwe imalola kuti ipitirire movutikira popanda kusweka, ndipo ndiyoyenera pazipangidwe zomwe zimafuna kupindika kapena kupindika.
Gulu C: Imakhala ndi mphamvu zochulukirapo komanso zokolola chifukwa cha kapangidwe kake, koma imatha kukhala yocheperako pang'ono poyerekeza ndi Gulu B.
Kusiyana kwa Ntchito
Ngakhale kuti zonsezi zimagwiritsidwa ntchito pamapangidwe ndi zothandizira, kutsindika kumakhala kosiyana.
Gulu B: Chifukwa cha kuwotcherera bwino ndi kupanga mapangidwe ake, nthawi zambiri amagwiritsidwa ntchito pomanga nyumba, kumanga mlatho, zomangira zomangira, ndi zina zotero, makamaka pamene zomanga zimafunika kuwotcherera ndi kupindika.
Gulu C: Chifukwa cha mphamvu zake zapamwamba, nthawi zambiri zimagwiritsidwa ntchito pazinthu zomwe zimakhala ndi katundu wambiri, monga zomangamanga za mafakitale, makina othandizira makina olemera, ndi zina zotero.
Kufanana
Ngakhale Giredi B ndi Sitandade C amasiyana m'njira zingapo, amagawananso mikhalidwe yofanana.
Mawonekedwe Ofanana a Cross-Section
Mawonekedwe apakati ndi ozungulira, ozungulira, amakona anayi, ndi oval.
Kutentha Chithandizo
Zonse zimalola kuti zitsulo zithetse nkhawa kapena kutsekedwa.
Mapulogalamu Oyesera omwewo
Magulu onse a B ndi C amayenera kukwaniritsa zofunikira za ASTM A500 pakuwunika kwamafuta, kusanthula kwazinthu, kuyesa kwamphamvu, Kuyesa kwa Flattening, Kuyesa Kwamoto, ndi Mayeso a Wedge Crush.
Kulekerera Kwamagawo Kofanana
Chitsanzo cha gawo lozungulira la dzenje.
Posankha kugwiritsa ntchito machubu a ASTM A500 Grade B kapena Grade C, zofunikira zenizeni za uinjiniya komanso kukwera mtengo kwake ziyenera kuganiziridwa.
Mwachitsanzo, pamapangidwe omwe safuna mphamvu zambiri koma kulimba kwabwino, Gulu B ikhoza kukhala chisankho chopanda ndalama.Kwa mapulojekiti omwe amafunikira mphamvu zambiri komanso mphamvu zonyamula katundu, Gulu C limapereka ntchito yofunikira, ngakhale pamtengo wapamwamba.
