1. Q: "ERW" thiab "Seamless" txhais li cas, thiab kuv yuav xaiv li cas?
A:ERW (Electric Resistance Welded) kav, zoo liA53 Hom E, muaj ib tug longitudinal weld seam. Lawv raug nqi -zoo rau ntau daim ntawv thov. Seamless kav, zoo liA53 Hom Slos yogA106 Qib B, tsis muaj seam, muab ntau lub zog sib xws thiab kev ua haujlwm zoo dua hauv siab -siab, tseem ceeb, lossis kev pabcuam corrosive.
2. Q: Dab tsi yog qhov tseem ceeb corrosion txaus ntshai rau cov kav hlau me me, thiab lawv yuav txo tau li cas?
A:Cov hlau me me yog raug rau xeb (oxidation) thiab galvanic corrosion. Txoj kev txo qis muaj xws li cov txheej txheem tiv thaiv (xim, epoxy, galvanizing - saibTom ntej: ASTM A53 F, uas yog galvanized), kev tiv thaiv cathodic, los yog siv cov hauv ob sab phlu. Kev xaiv cov khoom tseem ceeb heev; rau corrosive kua, alloys xws li stainless hlau tej zaum yuav xav tau.
3. Q: galvanized yeeb nkab yog dab tsi, thiab dab tsi specification npog nws?
A:Galvanized yeeb nkab muaj zinc txheej siv los ntawm kub -dip txheej txheem rau corrosion kuj.ASTM A53suav nrogHom F, uas yog rauv- pob tw welded thiab feem ntau galvanized, siv rau cov kav dej, laj kab, thiab qis - siab conveyance.
4. Q: Cov ntsiab lus carbon hauv ASTM A106 Qib A, B, thiab C cuam tshuam li cas?
A:Cov ntsiab lus carbon nce los ntawm Qib A (qis tshaj) mus rau Qib C (siab tshaj, mus txog 0.35%). Cov pa roj carbon ntau dua ua rau lub zog tensile tab sis me ntsis txo cov weldability thiab ductility.Qib Bmuab qhov zoo tshaj plaws tag nrho qhov sib npaug ntawm lub zog, weldability, thiab tus nqi, ua rau nws muaj ntau tshaj plaws.
5. Q: Dab tsi yog qhov zoo ntawm machining thiab vuam yam ntxwv ntawm me me steel yeeb nkab?
A:Qib zoo liA53 Qib BthiabA106 Qib Bmuaj qhov zoo tshaj plaws weldability siv txhua txoj hauv kev (SMAW, GMAW, GTAW). Preheating tsis tshua xav tau. Lawv kuj tshuab tau yooj yim, tsim cov chips tswj tau.
