Lipotso Tse Botsoang Khafetsa (Lipotso Tse Botsoang Khafetsa) - ASTM A500 GR.B SSAW Structure Pipe
P: Phapang ke efe pakeng tsa ASTM A500 GR.B le ASTM A252 GR.3?
A: ASTM A500 GR.B e na le matla a bonyane a tlhahiso a 315 MPa, ha ASTM A252 GR.3 e na le 345 MPa. A500 GR.B e na le mamello e tiileng mme e etselitsoe ho etsa moralo wa sebopeho. A252 GR.3 e etselitsoe ka ho khetheha bakeng sa ho kenya le ho kganna dikopo. A500 GR.B e fana ka bolelele bo phahameng (23% khahlano le 20%), e leng se bontshang ho ductility ho betere bakeng sa ho bopa.
P: Na ASTM A500 GR.B e ka sebediswa bakeng sa ho bokella dipeo?
K: E, ASTM A500 GR.B e ka sebediswa bakeng sa ditshebediso tsa ho bokella dipeipi, haholoholo bakeng sa ditlhoko tse bobebe tsa motheo. Leha ho le jwalo, bakeng sa ho bokella dipeipi tse boima tsa lewatle le tse tebileng tsa motheo, ASTM A252 GR.3 kapa EN 10248 S355GP di a kgothaletswa ka lebaka la matla a tsona a hodimo le ditlhoko tse ikgethang tsa ho kganna.
P: Bolelele bo boholo ba phala e le 'ngoe bakeng sa ASTM A500 GR.B SSAW ke bofe?
A: Bolelele bo tloaelehileng ke 6m, 12m, le 18m. Bolelele bo ikhethileng ho fihlela ho 60m boa fumaneha ho latela bophara le botenya ba lebota.
P: Ke dikgetho dife tsa ho qeta bokaholimo tse fumanehang?
K: Re fana ka dikobo tse hlobotseng (sekala sa tshilo), tse tlotsitsweng ka oli, tse foreimetsweng ka primer, tse ntsho tse manehilweng, tse tjhesitsweng ka ho tjhesa ka galvanized, le tse fapaneng tse thibelang ho bola.
P: Na o ka fana ka phaephe ya sebopeho ka tlhahlobo ya motho wa boraro?
K: E. Re thusa ho etsa ditlhahlobo ke SGS, BV, TÜV, DNV, kapa moemedi ofe kapa ofe ya kgethilweng ke moreki.
P: Ke litokomane life tse fanoang ka thomello ka 'ngoe?
A: Setifikeiti sa Teko ea Mill (EN 10204 Mofuta oa 3.1), Tlaleho ea Tlhahlobo ea Litekanyo, Litlaleho tsa UT, Litlaleho tsa RT (haeba ho boletsoe), Litokomane tsa ho Latela Lintho, Lethathamo la ho Paka, Invoice ea Khoebo, le Setifikeiti sa Tšimoloho.
