1. Dab tsi yog welded steel yeeb nkab?
Lub welded steel yeeb nkab yog tsim los ntawm dov ib tug steel sawb los yog phaj rau hauv ib tug tubular zoo thiab ces welding lub longitudinal los yog kauv seam. Nws txawv ntawm seamless yeeb nkab, uas tsis muaj weld seam.
2. Dab tsi yog yam tseem ceeb ntawm cov kav dej welded?
Hom loj:
Longitudinal submerged arc welded yeeb nkab (LSAW)
Kauv submerged arc welded yeeb nkab (SSAW / SAWH)
Siab - zaus welded yeeb nkab (ERW)
Hluav taws xob tsis kam welded yeeb nkab (EFW)
3. Qhov txawv ntawm ERW thiab seamless yeeb nkab yog dab tsi?
ERW cev: Nws muaj qhov vuam seam, tus nqi qis, qhov zoo ntawm qhov raug, haum rau nruab nrab - siv lub siab.
Seamless yeeb nkab: Tsis muaj weld seam, zoo dua lub siab ua haujlwm, tus nqi siab dua, siv rau siab -siab lossis kev pabcuam tseem ceeb.
4. ERW sawv cev rau dab tsi?
ERW =Electric Resistance Vuam, ib qho kev ua haujlwm siab - zaus vuam rau cov kav me thiab nruab nrab - qhov loj me.
5. Dab tsi yog cov qib steel rau welded kav?
Cov qhab nia:
Q195, Q215, Q235B
Q345B (16Mn)
GRB, API 5L Qib B, X42, X46, X52, X60, X65, X70
