Lipotso Tse Botsoang Khafetsa (Lipotso Tse Botsoang Khafetsa) - Pipe ea Tšepe ea ASTM A572 GR.50 SSAW
P: Phapang ke efe pakeng tsa tšepe ea ASTM A572 GR.50 le A36?
A: ASTM A572 GR.50 e na le matla a bonyane a tlhahiso a 345 MPa (50,000 psi), ha A36 e na le 250 MPa (36,000 psi). GR.50 e fana ka matla a tlhahiso a ka bang 38% a phahameng, e leng se lumellang meaho e bobebe le boholo bo fokotsehileng ba likarolo. GR.50 e boetse e na le khanyetso e ntlafetseng ea mafome a sepakapakeng ka lebaka la sebopeho sa eona sa HSLA.
P: Na ASTM A572 GR.50 e ka tjheselletswa ho sebediswa mekgwa e tlwaelehileng?
K: E, ASTM A572 GR.50 e na le bokgoni bo botle ba ho weld. Leha ho le jwalo, ka lebaka la matla a yona a hodimo le dikahare tsa alloy (columbium le vanadium), mekgwa ya ho weld ya haeterojene e tlase e a kgothaletswa. Ho futhumatsa ho ka hlokahala bakeng sa dikarolo tse teteaneng. Womic Steel e ka fana ka dikgothaletso tsa mekgwa ya ho weld ha ho kopuwa.
P: Phapang ke efe pakeng tsa ASTM A572 GR.50 le ASTM A992?
A: ASTM A572 GR.50 ke tlhaloso e akaretsang bakeng sa lipoleiti tsa tšepe tsa HSLA, libopeho le mekoallo. ASTM A992 e etselitsoe ka ho khetheha libalaka tse sephara le libopeho tsa sebopeho bakeng sa ho rala meaho. Ka bobeli li na le matla a tšoanang a tlhahiso (345-450 MPa), empa A992 e na le taolo e thata holim'a thepa ea thepa bakeng sa lits'ebetso tsa ho sisinyeha ha lefatše.
P: Bolelele bo boholo ba phala ea tšepe ea ASTM A572 GR.50 SSAW ke bofe?
A: Bolelele bo tloaelehileng ke 6m, 12m, le 18m. Bolelele bo ikhethileng bo fihlang ho 60m bo fumaneha ho latela bophara le botenya ba lebota. Bolelele bo bolelele bo eketsehileng bo loketse bakeng sa li-girger tsa borokho le lits'ebetso tsa meaho tse bolelele bo bolelele.
P: Ke dikgetho dife tsa ho qeta bokaholimo tse fumanehang bakeng sa ditshebediso tsa borokho?
K: Bakeng sa lits'ebetso tsa borokho, re fana ka pente ea primer, galvanizing e chesang, kapa litsamaiso tse khethehileng tsa ho thibela mafome (FBE, 3LPE, kapa pente ea epoxy). Tšepe ea Weathering (ASTM A588) e fumaneha hape bakeng sa lits'ebetso tsa borokho tse hlokang ho hanyetsa mafome a sepakapaka ntle le ho penta.
P: Na o ka fana ka phaephe ya ASTM A572 GR.50 ka tlhahlobo ya motho wa boraro?
K: E. Re thusa ho etsa ditlhahlobo ke SGS, BV, TÜV, DNV, ABS, LR, kapa moemedi ofe kapa ofe ya kgethilweng ke moreki nakong ya tlhahiso le pele ho thomello. 3.2 Disetifikeiti tsa tlhahlobo di fanwa ka mehla ha ho kopuwa.
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.
