Litlhaloso tsa Bohlokoa tsa ASTM

Libalaka tsa ASTM H (tse tsejoang hape e le libalaka tse pharaletseng tsa flange) hangata li hlahisoa ho latela maemo a latelang:

ASTM A36 Lehlaseli la H– Tšepe ea khabone e akaretsang bakeng sa mehaho le merero e menyenyane ea indasteri
ASTM A572 Lehlaseli la H– Tšepe ea HSLA e nang le karolelano e ntlafalitsoeng ea matla ho ea boima
ASTM A992 Lehlaseli la H– Sehlopha se kgethwang bakeng sa mahlasedi a sephara a sebopeho mmarakeng wa US
ASTM A588 Lehlaseli la H– Tšepe e hanelang ts'enyeho bakeng sa marokho le meaho ea kantle

Har'a tsena, mofuta o atileng haholo US keLehlakore la flange le pharaletseng la ASTM A992, e nang le matla a leka-lekaneng haholo, ho tjheseletsa le thepa ea ho ductility.

Likopo tse ka Sehloohong

Litšobotsi tse tloaelehileng tsa mechini (li fapana ho ea ka sehlopha):

Matla a Tekanyo: 250–345 MPa (36–50 ksi le ho feta)
Matla a tšepe: 400–550 MPa
Ho tjheseletsa le ho ba bonolo haholo
Ho hanyetsa ho matla ho kobeha le ho hatelloa

Karolo e bōpehileng joaloka H e fana ka:

1.Modulus ea karolo e phahameng

2. Kabo e sebetsang hantle ea mojaro

3. Tšebeliso e fokotsehileng ea tšepe ha e bapisoa le li-I-beam tsa setso

4. Tshebetso e ntle maemong a tshisinyeho ya lefatshe le a moya

Qeto ea ASTM H Beam

ASTM H Beam kapa Wide Flange Beam ke sehlahisoa se etellang pele kahong ea tšepe kajeno. Ho sa tsotelehe hore na projeke ke ea polokelo ea liindasteri, ea kaho ea tšepe ea khoebo, kapa ea boenjiniere ba borokho, libalaka tsa H tsa sebopeho sa ASTM li fana ka matla, botšepehi le ho latela melao lefatšeng ka bophara.

Ho barekisi ba tšepe le borakonteraka ba meaho, ho tla ba bohlokoa hore ba khethe mofani oa thepa ea boleng bo holimo ea tšepahalang ea ka fihlelang tlhoko ea boleng bo holimo le ea netefalitsoeng ke litekanyetso tsa machaba ho ba boloka ba qothisana lehlokoa selemong sa 2026 le ho feta.
