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.
Kwality Pipe & Tube Industries deliver LWC with cardboard reels. Coils on reel are stacked on wooden pallets and shrink wrapped. Level Wound Coils are specially suited to long production runs for industrial applications and it is widely applied to the Air Conditioning & Refrigeration as well as the Heat Exchanger field.
Most commonly supplied in the soft and light annealed form, also Level Wound Coils can be ordered in hard drawn temper.
