Level Wound Coil (LWC) Copper Tubes
Level Wound Coil (LWC) Copper Tubes The Level Wound Coil (LWC) Copper Tubes is one of our imported & supplied products. All LWC tubes are normally produced according to ASTM & Coproclima specifications. These specifications were prepared to take account of the requirements of ACR industry. Each millimetre of tubes is 100% Eddy-Current tested and any surface defects found will be clearly marked by black colour. For heavy coils, we wound LWC copper tubes in “Eye to Sky” (Jumbo) form as per customer request. The tube is cleaned with Nitrogen purging. Moreover to protect the tubes against dust & internal oxidation during transportation or long storing, the tube ends are sealed with plastic caps
Technical Specification :
- Specification: O.D: 3/16″ to 3/4″ (4.76 to 19.05 mm)
- Coil Weight: 100-400 Kg
- Application: Applied to the Air Conditioner, the Assembly Type Air Conditioning Unit, Refrigerator, Freezer, Chest, etc.
PANCAKE COPPER (PCC) TUBES
Pancake Copper (PCC) Tubes are widely used material in so many industries, commercial purposes etc. Copper has ductility features, and it also protects from natural corrosion resistance. Our manufactured Copper Tube Pan Cake Coil can easily be used in refrigeration, air conditioning, electrical application, solar application, and other general engineering purposes. Copper provides excellent ductile property and has the strength to work for extended-lasting usage.
