| Q1: Hauv kev lag luam twg yog seamless carbon steel kav feem ntau tseem ceeb? | Cov lag luam tseem ceeb muaj xws li:Roj & Roj(drilling, thauj),Lub zog tiam(Boiler tubes),Tshuaj & Petrochemical(reactors, tshav kub exchangers),Mechanical Manufacturing(Hydraulic thooj voos kheej kheej, bearings),Shipbuilding, thiabAutomotive -3-10. | |
| Q2: Vim li cas cov kav dej seamless nyiam rau kev siv siab -siab? | Qhov tsis muaj weld seam tshem tawm qhov muaj peev xwm tsis muaj zog, kom ntseeg tau tias cov khoom siv tsis sib xws thiabsiab dua -cov kabmob muaj peev xwmthiab kev nyab xeeb thoob plaws hauv cov yeeb nkab ncig -10. | |
| Q3: Dab tsi ntawm cov kav dej seamless siv hauv boilers? | Low/Medium{0}}Pressure Boilers: Siv cov kav dej rau GB 3087 (piv txwv li, qib 10, 20).Siab -Boilers siab: Siv cov kav dej ib GB 5310 (piv txwv li, qib 20G, 15CrMoG, 12Cr1MoVG) kom ua tau zoo tshaj - kub lub zog thiab oxidation tsis kam -3-4. | |
| Q4: Dab tsi yog lub ntsiab seamless yeeb nkab khoom siv hauv roj & roj drilling? | Cov khoom tseem ceeb suav nroglaum cev, casing, cev, thiabcore cev. Lawv xav tau lub zog siab, toughness, thiab hnav tsis kam (xws li DZ series qib) -3. | |
| Q5: Dab tsi yog qhov yuav tsum tau ua rau cov kav dej seamless siv hauv nkoj tsim khoom? | Lawv yuav tsum ua kom tau raws li cov cai tswjfwm hauv zej zog thiab cov qauv nruj (xws li GB / T 5312) rausiab ncaj ncees, corrosion kuj nyob rau hauv marine ib puag ncig, thiabkev ntseeg taurau lub nkoj tseem ceeb -1. |
