Q1: Yuav kuaj li cas Q235b Welded Pipes yuav tsum tau kuaj xyuas?
A1: Kev tshuaj xyuas ntau zaus nyob ntawm daim ntawv thov txhua xyoo yog raug rau cov qauv siv, thaum nias lub tebchaws yuav xav tau kev sim biannual. Harsh qhov chaw (cov tubrog nkoj, tshuaj lom neeg) yuav tsum tau soj ntsuam peb hlis. Pom kev pom rau xeb rau xeb, dents, lossis weld tawg yuav tsum muaj kev coj ua. Tsis yog-kev sim ua kev puas tsuaj (NDT) yog pom zoo rau cov ntsiab lus tseem ceeb.
Q2: Cov tsos ntawm cov yeeb nkab tsis zoo?
A2: Pom xeb, pitting, lossis flaking txheej qhia corrosion. Kev thuam, cov kab nrib pleb, lossis txi cov teeb meem tsis ua haujlwm. Weld Seam Seam sib cais lossis thinning phab ntsa yog chij liab. Discoloration lossis scaling tej zaum yuav teeb liab kev xeb hauv corrosion. Cov lus qhia ntxov tiv thaiv kev puas tsuaj loj.
Q3: Dab tsi NDT cov hau kev yog siv rau Q235B yeeb nkab tshuaj xyuas?
A3: Ultrasonic kev kuaj (ut) pom cov flaws sab hauv, thaum ntsuas hluav taws xob (RT) tshuaj ntsuam Weld kev ncaj ncees. Sib nqus particetle (MPI) pom cov kab nrib pleb hauv cov ntaub ntawv ferromagnetic. Zas kev sim tshuaj ntsuam (PT) qhia txog kev tsis xws luag nto. Hydrostatic kuaj xyuas cov lus pom zoo.
Q4: Yuav ua li cas yuav tsum corroded q235b yuav kho?
A4: lub teeb nto xeb tuaj yeem ntxuav tau thiab rov pleev xim. Cov chaw pitted yuav xav tau patching lossis lub tes tsho rov qab lub zog. Cov ntu muaj kev khwm croroded yuav tsum tau hloov. Kev kho tom qab, kev tiv thaiv txheej yuav tsum tau muab tso ua ke. Cathodic kev tiv thaiv tuaj yeem qeeb ntxiv corrosion.
Q5: Dab tsi yog qhov kev khaws cia zoo tshaj plaws rau kev siv Q235b zoo tshaj plaws?
A5: Khaws sab hauv tsev lossis hauv qab npog kom tiv thaiv noo noo. Ofate pipes ntawm ntoo pallets kom tsis txhob muaj av sib cuag. Siv Desiccants lossis VCI (Vapor Corrosion inhibitor) Ntawv hauv huab cua huab cua. Cov Pip Pipes tav toj nrog cov tog raj los tiv thaiv deformation. Tshawb xyuas ib txwm ua kom muaj xeb thaum ntxov.
