Litaba - Likhoele tsa Tšepe tse Phehiloeng tse Chesang tse Tloaelehileng tsa ASTM: Likereiti tsa Bohlokoa, Likarolo le Litšebeliso tsa Liindasteri

Likhoele tsa tšepe tse phutholohileng tse chesang(HRC)tse entsoeng ho latela maemo a ASTM ke tse ling tsa lihlahisoa tsa tšepe tse sebelisoang haholo 'marakeng oa lefats'e, haholo-holo ho pholletsa le Amerika Leboea le Boroa. Ka lebaka la thepa ea tsona e tsitsitseng ea mechini, khetho e pharaletseng ea maemo, le bokhoni ba litšenyehelo, likhoele tsa tšepe tse phutholohileng tsa ASTM li bapala karolo ea bohlokoa kahong, tlhahisong, likoloing le indastering e boima.

Ho latela ts'ebetso ea mechini le litlhoko tsa ts'ebeliso, likhoele tsa tšepe tse phutholohileng tse chesang tsa ASTM ka kakaretso li ka aroloa ka mekhahlelo e meraro e meholo: tšepe ea sebopeho sa khabone, tšepe ea low-alloy e matla haholo (HSLA), le tšepe ea boleng bo holimo le ea khoebo.

1. Likereiti tsa Tšepe ea Meaho ea Khabone

Mekhahlelo e tloaelehileng e kenyelletsa ASTM A36, ASTM A283 Kereiti ea C, le ASTM A1011 SS36 / SS40. Mekhahlelo ena e nkoa e le likhoele tsa tšepe tsa khabone tse chesang tse phutholohileng tse atileng haholo le tse feto-fetohang 'marakeng oa Amerika.

Likhoele tsa tšepe tsa mohaho oa khabone li tsebahala ka matla a tsona a leka-lekaneng, ho tjheseletsa hantle, le bonolo ba ho etsoa. Li fana ka ts'ebetso e tšepahalang tlas'a maemo a tloaelehileng a mojaro 'me li loketse mefuta e mengata ea lits'ebetso tsa boenjiniere ka kakaretso.

Ha e le hantle, thepa ena e sebelisoa haholo mehahong ea tšepe, li-bracket, lipoleiti tsa motheo, liforeimi le likarolo tsa tlhahiso ka kakaretso. Ka lebaka la kamohelo ea tsona lefatšeng ka bophara le phepelo e tsitsitseng, limaraka tsa HRC tsa sebopeho sa khabone tsa ASTM hangata ke khetho ea pele bakeng sa merero e shebaneng le kantle ho naha le mesebetsi ea kaho e tloaelehileng.

2. Mekhahlelo ea Tšepe e Matla a Phahameng (HSLA)

Bakeng sa merero e hlokang matla a phahameng le bokgoni bo ntlafetseng ba boima, ASTM A572 Kereiti ya 50, ASTM A992, le ASTM A1011 HSLAS Kereiti ya 50 hangata di a hlaloswa.

Likhoele tsa tšepe tse phutholohileng tse chesang tsa HSLA li entsoe ho fana ka chai e phahameng le matla a ho thapolla ha li ntse li boloka ho tjheseletsa le ho tiea hantle. Ha li bapisoa le tšepe ea khabone e tloaelehileng, limaraka tsena li lumella baenjiniere ho fokotsa tšebeliso ea tšepe ntle le ho beha polokeho ea sebopeho kotsing, e leng se etsang hore li be ntle bakeng sa mehaho e meholo le e jarang mojaro.

Mekhoa e tloaelehileng e kenyelletsa marokho, mehaho e meholo ea tšepe, lifeme tsa indasteri, matlo a polokelo le liforeimi tsa lisebelisoa tse boima. ASTM A992, haholo-holo, e se e le thepa e tloaelehileng bakeng sa maballo a meaho le likholomo kahong ea tšepe ea mehleng ea kajeno ea Amerika.

3. Tšepe e Chesang e Menoang ea Khoebo le ea Boleng bo Holimo

Mekhahlelo e kang ASTM A1011 CS Type B le ASTM A1011 DS e entsoe ho nahanoa ka boleng ba bokaholimo le ho bōpeha habonolo.

Likhoele tse phutholohileng tse chesang tsa tšepe ea khoebo (CS) li fana ka botenya bo tsitsitseng le libaka tse boreleli, e leng se etsang hore li lokele ho etsoa ka kakaretso le ho etsoa ka mokhoa o bobebe. Ka lehlakoreng le leng, tšepe e hulang (DS) e fana ka matla a eketsehileng a ho sebetsa le ho fetoha ho ts'oanang, e leng se nolofalletsang ts'ebetso e rarahaneng ea ho hatakela le ho kobeha.

Mekhahlelo ena e sebelisoa haholo likarolong tsa likoloi, lisebelisoa tsa ntlo, li-enclosure, liphanele le lihlahisoa tse entsoeng ka serame, moo ho theha ts'ebetso le ponahalo ea bokaholimo e leng lintlha tsa bohlokoa.

Matla a Phepelo le Melemo ea Tšebeletso ea Royal Group

Royal Group e fana ka tharollo ea phepelo ea sebaka se le seng bakeng sa likhoele tsa tšepe tse phutholohileng tse chesang tsa ASTM, ho kenyeletsoa:

Kakaretso ea maemo a pharaletseng: ASTM A36, A283 Gr.C, A572 Gr.50, A992, A1011 CS / DS / HSLAS

Boholo bo tenyetsehang le lits'ebeletso tsa ho seha tse ikhethileng

Sephutheloana sa kantle ho naha sa litsebi bakeng sa likhoele tsa tšepe

Nako e tsitsitseng ea ho etella pele le tšehetso ea lefats'e ea thepa

Tšehetso ea tekheniki le karabelo e potlakileng ea khotheishene

Ka ho kopanya boleng bo tšepahalang ba sehlahisoa le tšebeletso e sebetsang hantle, Royal Group e ntse e tsoela pele ho thusa bareki ba lefats'e ka bophara ho fokotsa likotsi tsa theko le ho ntlafatsa ts'ebetso ea ketane ea phepelo.

Ho Tšehetsa Merero ea Tšepe ea Lefatše ka Kholiseho

Ho tloha ho likhoele tsa tšepe tsa khabone tse tloaelehileng ho isa ho likhoele tsa tšepe tsa HSLA tse matla haholo le likhoele tsa tšepe tse chesang tsa khoebo, Royal Group e ntse e ikemiselitse ho fana ka litharollo tsa tšepe e chesang e phutholohileng tse lumellanang le ASTM bakeng sa kaho, tlhahiso le lits'ebetso tsa indasteri lefatšeng ka bophara.

Ha nts'etsopele ea meralo ea motheo le tlhahiso ea indasteri li ntse li tsoela pele ho atoloha lefatšeng ka bophara, likhoele tsa tšepe tse phutholohileng tsa ASTM tsa Royal Group li tla lula e le khetho e tšepahalang bakeng sa balekane ba batlang boleng, botsitso le tšebelisano-'moho ea nako e telele.
