ASTM A325 / A325M Heavy Hex Structural Bolts

Ma bolts amapangidwa kuti agwiritsidwe ntchito polumikizana ndi zomangamanga. Malumikizidwewa akukhudzidwa ndi zofunikira za Specification for Structural Joints Kugwiritsa Ntchito Maboti a ASTM A325, ovomerezedwa ndi Research Council on Structural Connections, ovomerezedwa ndi American Institute of Steel Construction ndi Industrial Fastener Institute.

Kukula: ASME B18.2.6 (Inchi Kukula), ASME B18.2.3.7M (Metric Kukula)

Kukula kwa Ulusi: 1/2″-1.1/2″, M12-M36, ndi utali wosiyanasiyana

Gulu: ASTM A325 / A325M Type-1

Malizitsani: Black Oxide, Zinc Plating, Hot Dip galvanized, Dacromet, ndi zina zotero

Kulongedza: Chochuluka pafupifupi 25 kgs katoni iliyonse, makatoni 36 aliwonse phale

Ubwino: Ubwino Wapamwamba ndi Kuwongolera Kwabwino Kwambiri, Mtengo Wopikisana, Kutumiza munthawi yake; Thandizo laukadaulo, Malipoti a Supply Test

Chonde khalani omasuka kulankhula nafe kuti mumve zambiri.

Mu 2016, ASTM A325 idachotsedwa mwalamulo ndikusinthidwa ndi ASTM F3125, pomwe A325 tsopano imakhala giredi pansi pa F3125. Mafotokozedwe a F3125 ndikuphatikiza ndikusintha miyezo isanu ndi umodzi ya ASTM, kuphatikiza; A325, A325M, A490, A490M, F1852, ndi F2280.

Isanatulutsidwe mu 2016, mawonekedwe a ASTM A325 anali ndi ma bolt amphamvu kwambiri a hex kuchokera pa 1/2 ″ m'mimba mwake mpaka 1-1/2 ″. Mabotiwa amapangidwa kuti azigwiritsidwa ntchito polumikizana ndi kamangidwe kotero amakhala ndi ulusi wamfupi kuposa ma bawuti wamba a hex.

Izi zimagwira ntchito pamaboti olemetsa a hex okha. Pamaboliti amasinthidwe ena ndi kutalika kwa ulusi wokhala ndi makina amakina ofanana, onani Specification A449.

Maboti ogwiritsira ntchito wamba, kuphatikiza mabawuti a nangula, amaphimbidwa ndi Specification A449. Onaninso Specification A449 yazitsulo zozimitsidwa ndi zitsulo zozimitsidwa ndi zitsulo zokhala ndi ma diameter akulu kuposa 1-1/2 ″ koma zokhala ndi makina ofanana.

Chithunzi cha ASTM A325

Mbali
Mafotokozedwe a ASTM A325 amakwirira mabawuti amphamvu kwambiri a hex kuchokera m'mimba mwake ½ mpaka 1-1/2". Mabotiwa amapangidwa kuti azigwiritsidwa ntchito polumikizana ndi kamangidwe kotero amakhala ndi ulusi wamfupi kuposa ma bawuti wamba a hex. Onani tsamba la Structural Bolts patsamba lathu kuti muwone kutalika kwa ulusi ndi miyeso ina yofananira.
