�PRODUCTION�TECHNIQUE�&�APPLICATIONS�
1. ‘G’�Fin�(also�called�“Embedded�Fin”�or�“Edge�Grooved�Fin”)�:�The�fin�strip�is�wound�into�a�machined� groove� and� securely� locked� into� place� by� back� filling� with� base� tube�material�under�pressure.�This�ensures�that�maximum�heat�transfer�is�maintained�at�high�tube�metal�temperatures.�Maximum�operating�temperatures�for�this�fin�type�is�450°C.��
2. ‘L’� Fin� (also� called� “Shoulder� Tension� Fins”,� “Wrap� On� Fins”)� :� The� strip� material� is�subjected�to�controlled�deformation�under�tension�giving�the�optimum�contact�pressure�at�the� foot�of� the� fin�onto� the�base� tube� thus�maximizing� the�heat� transfer�properties.� The�foot�of�the�fin�considerably�enhances�the�corrosion�protection�of�the�base�tube.�Maximum�operating�temperature�for�this�fin�type�is�150°C.��
3. ‘KL’�Fin�(also�called�Knurled�“L”� fin)� :�Manufactured�exactly�as� the� ‘� L’� fin�except� that� the�base� tube� is� knurled� before� application� of� the� fin� foot.� After� application� the� fin� foot� is�knurled� into� the� corresponding� knurling� on� the� base� tube� thereby� enhancing� the� bond�between� the� fin� and� tube� resulting� in� improved� heat� transfer� characteristics.� Maximum�operating�temperature�for�this�fin�type�is�260°C.��
4. Extruded�Fin�(Bimetallic�Fin�)�:�The��main�tube�(mother�tube)�is�covered�with�an�Aluminum�Muff� and� the� fins� are� formed� using� the� forming� force.� This� results� into� very� good�mechanical�bonding�of�the�Aluminum�Muff�with�the�mother�tube�to�have�a�very�good�heat�transfer� properties.� The� fins� cover� the� whole� tube� &� have� a� very� good� anti�corrosive�properties.�Maximum�operating�temperature�for�this�type�of�fin�is�350°C.�
