Processus de:
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: Les tuyaux en acier pour restes explosifs des guerres sont moins chers que PIPE EN ACIER SANS SOUDURE.|
2) Haute précision: Les tuyaux en acier ERW ont une tolérance plus étroite en matière d'épaisseur de paroi par rapport à PIPE EN ACIER SANS SOUDURE.
