Yeyiphi imigangatho ye-ASTM A193 B7 inyibilikiswe intonga?

Imigangatho yeI-ASTM A36 YENKULUMKOGquma iiparameter ezininzi ezinje ngomhlaba ochanekileyo, okhokela kunye nobude. Xa uyila, kuyimfuneko ukukhetha iinkcazo ezifanelekileyo ngokweemfuno ezithile zesicelo kunye nomthwalo womthwalo.

I-A193 B7 yonke intamboI-A449 ye-A449 ikhutshiwe i-diamere ye-A44

I-A449 ye-A449 yentongabanoluhlu olubanzi lweedayamitha ezichanekileyo, kunye neenkcazo eziqhelekileyoI-rod esemgangathweni ye-rod yemvelisoAli-12, 14, 20, 25, 40, 40, 50, 63, 8, 12, njl. Ubungakanani be-diamell bulungelelane ngokusisiseko komthamo, oko kukuthi, ukhule ububanzi, kokukhona umthwalo omkhulu. Xa uyila, umthwalo oqikelelweyo oqingqiweyo kufuneka ubhekiselwe kuyo, apho umthwalo oqingqiweyo ojikelezayo ubhekisa kumthwalo we-axial oqingqiweyo kwimo eshukumayo, kwaye umthwalo oqikelelweyo ubhekisa kumthwalo we-axial oqingqiweyo kwimo ye-axial. Ngokwenene, umthwalo ophakathi awunguye umthwalo ophezulu. Umlinganiso omncinci womthwalo ongumthwalo olinganiselweyo, ixesha elide ubomi bethiyori ye-screw.

I-Stainess Steeles Teeed I-Astm ikhokelela

Kwakhona waziwa njenge-pitch, ibhekisa kumgama i-nut yenqeni ihamba ngomgca wokujikeleza nganye yesikrelem.I-Stainess Steell I-Steeed Roread Asstm AsstmIinkcazo ezikhokelayo eziqhelekileyo zibandakanya 1, 2, 6, 8, 20, 20, 4, 4, 4, 20 ,. njl njl. I-Cound ihambelana nesantya somgca. Xa isantya sokufaka sihlala sihlala sikhulu, ukhulu ukukhohlisa, ngokukhawuleza isantya.

I-ASTM F593 ubude beentonga ze-rod

Ubude beI-ASTM F593 Iimveliso zeRoread eziNtandoKubandakanya iikhonsepthi ezimbini: ubude bubo bonke kunye nobude bentambo. Xa uyila kwaye uzonde, ubude becala le-screw bunokuqokelelwa ngokulandelayo: Ubude be-screw firgin + ubude bokufaka + ububanzi be-Nations (ukuba ububanzi be-strging) ubude be-coupling + brging). Kubaluleke kakhulu ukuqaphela ukuba ubude besikere bude bude (bukhulu kakhulu kwiimitha ezi-3) okanye umlinganiselo othile ophezulu (omkhulu kuno-70), uyilo lwayo lunokufuna ingqalelo ekhethekileyo.
