PebA500 Qib A Kub-Dip Galvanized Round Pipeyog tsim los ntawm siab - zoo carbon steel rauASTM A500 1(cov khoom siv hauv paus) thiab kub -dip galvanized nyob rau hauv nruj raws liASTM A123/A123Mqauv. Cov yeeb nkab nta ayam tsawg kawg nkaus 45μm zinc txheej(nruab nrab tuab), xa cov kev tiv thaiv corrosion tshwj xeeb, lub zog muaj zog, thiab ntev - lub sijhawm ua haujlwm ntev rau sab nraum zoov, kev lag luam, thiab corrosive- daim ntawv thov ib puag ncig. The hot-dip galvanization process forms a dense, uniform zinc-iron alloy layer that bonds metallurgically with the steel, providing sacrificial anode protection and extending service life by20+ xyoonyob rau hauv tej yam hnyav.

FAQ
Q1: Dab tsi yog qhov txawv ntawm ASTM A123 thiab lwm cov qauv galvanization?
A123 yog thawj US tus qauv rau kub-dip galvanized txheej ntawm cov khoom siv hlau (nrog rau cov kav dej). Nws qhia qhov tsawg kawg nkaus txheej thickness (45μm rau cov kav dej<3mm thick), surface quality, and adhesion requirements. Unlike electro-galvanization (thinner coating, ~5–15μm), A123 hot-dip galvanization provides a thick, durable zinc-iron alloy layer for long-term corrosion resistance.
Q2: Lub 45μm zinc txheej puas tuaj yeem kho tau?
Yog lawm. Peb muab cov txheej txheem kho dua tshiab:65μmsiv rau ntug hiav txwv / sab nraum zoov,85μmrau industrial / chemical ib puag ncig, thiab100μm+rau faus / underwater daim ntaub ntawv. Tag nrho cov txheej txheem kev cai ua raws li ASTM A123.
Q3: Puas yog cov yeeb nkab haum rau vuam?
Yog lawm. A500 Qib A steel yog weldable nrog cov txheej txheem (MIG, TIG, stick). Weld cheeb tsam poob txheej tiv thaiv; siv zinc-nplua nuj xim los yog kub-dip kov-nce rau ASTM A780 kho.
Q4: Cov kev ntsuam xyuas zoo li cas?
Zinc Txheej ThicknessASTM E376 Kev ntsuas qhov sib nqus
Txheej hnyav: Gravimetric test (stripping thiab hnyav).
Adhesion: Khoov kuaj (tsis muaj cracking / flaking).
Dimensional Check: OD, WT, ntev, qhov tseeb tseeb.
Mechanical Properties: Tensile thiab yield zog xeem.
Q5: Lub sijhawm ua khoom lag luam yog dab tsi?
Standard qhov ntau thiab tsawg:7-14 hnub; customizes/lengths:14-21 hnub. Kev txiav txim ntau (Ntau dua lossis sib npaug rau 50 tons): lub sijhawm ua haujlwm sib tham.
Q6: Koj puas muab daim ntawv pov thawj?
Yog lawm. Peb muabMill Test Certificate (MTC)nrog chemical / mechanical zog,ASTM A123 Daim Ntawv Pov Thawj Ua Raws Cai, thiabISO 9001 Daim Ntawv Pov Thawj Zoorau tag nrho cov khoom xa tuaj.
