ASTM A131 Fasalka A / B saxan birta badda

ASTM A131 waa qaab dhismeed oo saxan bir ah oo si gaar ah loogu isticmaalo warshadaha dhismaha maraakiibta. Darajadan waxa lagu qeexay xoog caadi ah oo leh wax-soosaarka ugu yar ee 34KSI(235Mpa). Codsiyada waxaa ka mid ah doonyaha, qalabka badda iyo dhismaha markabka. Darajooyinkan waxaa sidoo kale shahaado siisay Xafiiska Maraykanka ee Maraakiibta (ABS)

Soo bandhigid kooban oo saxan birta badda ah iyo xoogga caadiga ah ee A131
Saxanka birta badda waxaa loola jeedaa birta qaab dhismeedka ee loo isticmaalo dhismaha markabka. Waxaa loo tixgaliyaa darajada badda waana in ay iska caabiso waxyeelada xun ee ku badan deegaanka biyaha. Si taas loo gaaro, walxaha alloying gaar ah ayaa lagu daraa in darajooyinkan si ay u difaacaan daxalka agist. Iyadoo inta badan birta kaarboon ma aha ku haboon deegaanka badda, waxaa jira dhowr steels carbon heerka badda in ay ansixiyeen by bulshooyinka kala duwan codsiyada dhismaha maraakiibta.

Birta qaab dhismeedka ee hulalka markabka waxay u qaybsantaa fasalo xoog badan iyadoo loo eegayo awoodeeda waxsoosaarka ugu yar: birta qaab dhismeedka guud iyo xooga sare ee birta qaab dhismeedka. Saxan birta Maine waxaa loola jeedaa saxan bir duuban oo kulul oo la soo saaray iyadoo la raacayo shuruudaha bulshada qadiimiga ah ee dhismaha dhismayaasha qolofta markabka. Biraha guud ee birta ee Bulshada Kala-saarista Shiinaha waxa loo qaybiyaa afar darajooyin oo tayo leh: A B D iyo E.

Waxaa jira 9 bulshooyinka kala-soocidda ee adduunka oo dhan.

ASTM A131 waa qaab dhismeed oo saxan bir ah oo si gaar ah loogu isticmaalo warshadaha dhismaha maraakiibta. Darajadan waxa lagu qeexay xoog caadi ah oo leh wax-soosaarka ugu yar ee 34KSI(235Mpa). Codsiyada waxaa ka mid ah doonyaha, qalabka badda iyo dhismaha markabka. Darajooyinkan waxaa sidoo kale shahaado siisay Xafiiska Maraykanka ee Maraakiibta (ABS)

Tilmaamahan waxa uu daboolayaa taarikada birta qaab dhismeedka, qaababka, baararka iyo jeexjeexyada loogu talagalay in loogu isticmaalo dhismaha markabka.
Xoogga caadiga ah- Fasalka A B D CS iyo E oo leh dhibicda ugu yar ee la cayimay ee 34 ksi(235MPa)

Dhisidda maraakiibtu waxay udub dhexaad u tahay aqoonsiga Ameerika iyo caqli-galnimada Maraykanku waxay ka iftiimaysaa maraakiibteeda quusta, doonyaha doonyaha, maraakiibta dalxiiska, iyo kuwa qaada diyaaradaha. Maraakiibta waaweyni waxay ku bilowdaan saxan bir ah oo tayo sare leh, Gnee waxay ku faantaa inay siiso warshadaha samaynta maraakiibta Maraykanka birta badda iyo xeebaha taas oo ah mid u adkaysata daxalka oo adag, taasoo muujinaysa jajabnaanta hoos u dhacday, xitaa heerkulka qabow, iyo korodhka xoog si looga hortago dhaawacyada gariir. Dhammaan saxannadayada heerka badeedku waxay buuxiyeen heerarka ay dejisay ABS (Xarunta Dhismaha Maraakiibta Mareykanka), ASTM, iyo API (Machadka Batroolka Mareykanka). Waxaan nahay alaab-qeybiye la aamini karo oo ah birta badda iyo badda ee adduunka oo dhan iyo kuwa dhisayaasha adeegga
