RESTES EXPLOSIFS DE GUERRE (Soudé par résistance électrique)
HFI (Induction haute fréquence)
EFW(FUSION ÉLECTRIQUE TUBE SOUDÉ)
HFW(Soudure haute fréquence)
Caractéristique du tube soudé par résistance électrique (Tubes soudés par résistance électrique);
1) Avantages de l’économie: Tube soudé par résistance électrique en acier est moins cher que les tuyaux en acier sans soudure.|
2) Haute précision: Tube soudé par résistance électrique en acier a une tolérance plus près du mur épaisseur whencompared avec des tuyaux en acier sans soudure.
