Q1: Dab tsi yog cov qib carbon steel ntau tshaj plaws rau siab - qhov kev pabcuam kub hauv cov txheej txheem piping?
A:ASTM A106 Gr.B yog dav siv rau siab - kev pabcuam kub txog li 750℃F (399℃).
Q2: Qib twg yog qhov zoo dua rau siab -siab hydraulic systems?
A:ASTM A519 1020/1026 DOM (Drawn Over Mandrel) tubing muaj lub zog zoo heev thiab ua kom tiav.
Q3: Qhov txawv ntawm API 5L Gr.B thiab X42 yog dab tsi?
A:API 5L Gr.B muaj qhov tsawg kawg nkaus yield zog ntawm 35,000 psi, thaum X42 muaj 42,000 psi; X42 yog siv rau siab dua - cov kav dej siab.
Q4: Dab tsi stainless hlau qib resists chloride -induced stress corrosion cracking?
A:Duplex 2205 (UNS S31803) muaj kev tiv thaiv zoo dua piv rau 304 lossis 316.
