1. Q: Dab tsi yog "Skelp" hauv kev tsim cov yeeb nkab?
A:Skelp yog cov khoom pib rauweldedyeeb nkab ntau lawm (ib tug dov steel strip). Nws tsis yog siv rau seamless yeeb nkab ntau lawm, uas pib nrog ib tug khoom billet.
2. Q: "PE" txheej txhais li cas rau cov kav dej?
A:"PE" sawv cev rau Polyethylene. Nws yog ib qho kev tiv thaiv sab nraud los tiv thaiv-corrosion txheej (feem ntau siv los ntawm extrusion) siv rau cov kav dej xws li API 5L kab kav dej los tiv thaiv lawv ntawm av corrosion thaum lub sij hawm faus kev pab cuam.
3. Q: Dab tsi yog "Galvanizing" ntawm cov kav hlau steel? Puas yog cov kav dej seamless?
A:Galvanizing yog txheej txheem ntawm kev siv cov zinc txheej tiv thaiv kom tsis txhob xeb. Nws muaj ntau heev rau me me - txoj kab uas hla welded kav (ASTM A53) siv rau qis - siab conveyance. Nws tsis tshua muaj tshwm sim rau cov kav dej seamless siv hauv siab - kev pabcuam siab / kub, vim tias qhov kub ntawm vuam lossis kev pabcuam tuaj yeem ua rau cov zinc txheej puas.
4. Q: Dab tsi yog "Dub" thiab "Liab" yeeb nkab?
A:"Dub yeeb nkab" feem ntau yog hais txog cov yeeb nkab steel nrog tsaus, hlau - oxide nplai ntawm nws qhov chaw los ntawm kev kub kub, feem ntau siv rau cov roj lossis dej. "Liab yeeb nkab" txhais tau hais tias cov yeeb nkab yog muab tsis muaj txheej los yog plating.
5. Q: Yuav ua li cas nce cov ntsiab lus carbon feem ntau cuam tshuam rau cov khoom ntawm carbon steel yeeb nkab?
A:Ua kom cov pa roj carbon ntau ntxiv ua rau lub zog tensile thiab hardness tab sis txo qis ductility, weldability, thiab toughness. Tsawg- carbon steels (piv txwv li, 0.2% C) yog ntau dua ductile thiab weldable, thaum siab dua - carbon steels muaj zog tab sis ntau nkig.
