Imitwe minini ya mpandeshatu igizwe na ASTM A 325 / ASTM A 490

1.Ibihe bigenewebinini binini byumutwe?

Bolt ifite imitwe minini ya mpandeshatu ni feri ikoreshwa muguhuza ibyuma bikomeye cyane. Umutwe wacyo nuburyo bunini bwa mpande esheshatu zishobora kwihanganira imbaraga-ndende zikomeye kandi zogosha. Barashobora gutanga imiyoboro yizewe kandi yizewe, kuburyo ikoreshwa cyane mubiraro, inyubako, gari ya moshi, umuhanda munini, nindi mishinga minini.

2.Ni irihe tandukaniro riri hagatiASTM A325na ASTM A490?

ASTM A325 na ASTM A490 byombi nibisobanuro byihariye kuri bolts ikoreshwa mumutwe munini wa mpande esheshatu. Baratandukanye mu mbaraga z'umubiri. ASTM A325 isanzwe ikoreshwa muburyo bukomeye bwo hagati, mugihe ASTM A490 ikoreshwa muburyo bunini, buremerewe cyane.

A325 bolts igizwe ahanini na TYPE1 na TYPE3. TYPE1 ikoreshwa muburyo rusange kandi irashobora kuba hot-dip galvanisation nibiba ngombwa. Ibyuma birwanya ikirere bizakoreshwa hamwe na TYPE3, bizashyirwaho ikimenyetso cyihariye mugushushanya mugihe TYPE3 ikoreshwa.

Imbaraga zifatika za A490 ziri hejuru ya A325, ariko A490 ntishobora kuba Hot-dip galvanisation. A490 bolts igabanijwe muburyo butatu bwubwoko bwa TYPE3 hamwe nicyuma kimwe cyikirere.A325 na A490gira diametero zisanzwe mubirenge no kwiyongera kwa metero 1/8, zombi hagati ya metero 1 na metero 1.5, hamwe na diametero hafi ya metero 1 zikoreshwa cyane.

3.Ni iki ASME B18.2.6-2010?

ASME B18.2.6-2010 ni igipimo cyabanyamerika kigaragaza ibisabwa mubipimo, ibikoresho, imashini nubumashini, gukora, no gushyira ibimenyetso bya bolts kumutwe munini wa mpande esheshatu.

4.Ni uwuhe murimo wa bolts kumutwe munini wa mpande esheshatu?

Igikorwa nyamukuru cya bolts ikoreshwa muburyo bunini bwa hexagonal imitwe ni uguhuza ibice bitandukanye byimiterere yicyuma, bigatuma ibice byose hamwe. Barashobora kwihanganira imbaraga-zikomeye kandi bakagira imitingito n’umuyaga mwinshi. Kubwibyo, bolts kumutwe munini wa mpande esheshatu nubwoko bwingenzi bwihuta mubwubatsi.
