Mitu yayikulu yamakona atatu amaboti ASTM A 325/ASTM A490

1.Kodi mabawuti ndi a chiyanizikuluzikulu za mutu wa hexagonal?

Maboti okhala ndi mitu yayikulu ya hexagonal ndi zomangira zomwe zimagwiritsidwa ntchito polumikiza zida zachitsulo zamphamvu kwambiri. Mutu wake ndi wawukulu wa mawonekedwe a hexagonal omwe amatha kupirira mphamvu zolimba kwambiri komanso zometa ubweya. Atha kupereka maulalo otetezeka komanso odalirika, motero amagwiritsidwa ntchito kwambiri m'milatho, nyumba, njanji, misewu yayikulu, ndi ntchito zina zazikulu.

2.Kodi pali kusiyana kotani pakatiChithunzi cha ASTM A325ndi ASTM A490?

ASTM A325 ndi ASTM A490 zonse ndizomwe zimayikidwa pamabatire omwe amagwiritsidwa ntchito pamapangidwe akulu amutu a hexagonal. Amasiyana mphamvu zakuthupi. ASTM A325 imagwiritsidwa ntchito popanga zida zapakati, pomwe ASTM A490 imagwiritsidwa ntchito pazinthu zazikulu, zodzaza kwambiri.

Maboti a A325 amapangidwa makamaka ndi TYPE1 ndi TYPE3. TYPE1 imagwiritsidwa ntchito popanga wamba ndipo imatha kukhala yotenthetsera ngati kuli kofunikira. Chitsulo chosamva nyengo chidzagwiritsidwa ntchito limodzi ndi mabawuti a TYPE3, omwe azidzalembedwa mwapadera pachojambula akamagwiritsidwa ntchito mabawuti a TYPE3.

Mphamvu yakuthupi ya bawuti ya A490 ndiyokwera kuposa A325, koma bawuti ya A490 singakhale galasi yotentha. Maboti a A490 amagawidwa m'mitundu itatu ya ma bawuti amtundu wa TYPE3 okhala ndi chitsulo chofanana ndi nyengo.A325 ndi A490 mabawutiali ndi mainchesi okhazikika pamapazi ndi ma increments a 1/8 mapazi, onse pakati pa 1 phazi ndi 1.5 mapazi, okhala ndi mainchesi ozungulira phazi limodzi amagwiritsidwa ntchito kwambiri.

3.Kodi ASME B18.2.6-2010 ndi chiyani?

ASME B18.2.6-2010 ndi muyezo waku America womwe umatchula zofunikira pamiyeso, zida, makina ndi mankhwala, kupanga, ndi kuyika chizindikiro ma bawuti pamitu yayikulu yamakona atatu.

4.Kodi ma bolts azinthu zazikulu za mutu wa hexagonal ndi chiyani?

Ntchito yaikulu ya ma bolts omwe amagwiritsidwa ntchito m'magulu akuluakulu a mutu wa hexagonal ndikugwirizanitsa mbali zosiyanasiyana zazitsulo, kupanga zigawo zonse. Amatha kupirira mphamvu zamphamvu kwambiri komanso amakhala ndi zivomezi zazikulu komanso kukana mphepo. Chifukwa chake, mabawuti amitu yayikulu ya hexagonal ndi mtundu wofunikira kwambiri wamakina omanga.
