Bu tip serpantinlerde boru ve kanat birbirine, tam teması sağlamak için, MIG kaynak yöntemi ile tutturulur. Kaynak işleminin uygulanabilmesi için kanat kalınlığının en az 1 mm olması gerekir. Boru ve kanat birbirine kaynakla birleştirilmiş olduğu için bu şekilde üretilen serpantinler, punta kaynaklı serpantinlere göre çok daha yüksek sıcaklıklarda kullanılabilir. |
High frequency welded serpentines are the most special type among spiral finned serpentines. These serpentines have especially high heat resistance, because their minimum fin thickness is 0.8mm. For high frequency welded serpentines, high frequency electric energy is applied to fin and tube, which creates compete fusion and penetration between the tube and the fin. With complete contact created with this welding process, serpentine’s heat transfer and mechanical resistance increases and fin-tube form is maintained even at high temperatures. |
Fin is mechanically embedded in a grove to the tube surface and wrapped. Maximum working heat is 400°C. It is produced with carbon steel, Cr-Mo steel, stainless steel, copper and copper alloyed tubes, copper and aluminum fin material. |
L shaped fin is wrapped by being stretched on tube. Maximum working heat is 150℃. It is produced with all tube types and copper and aluminum fin material. |
