 - Formed by combining multiple circles and layers into one whole, leading to larger surface and space for heat-exchanging, and better working performance. 
 - Each single-layer of coil is made by one tube without any intermediate connections. There is only one solder connection joining the two layers of a coil, leading to better anti-leaking performance.
 - The connection joining the two layers could be one of three possible forms: Butt welding, Spigot brazing, or Spigot connecting thread.
 - Applicable for heat-exchanger or beer cooling process

- Stainless-steel coil is designed primarily for heat-exchanging. Due to the operating condition of heat-exchanging process between different heat mediums (fluid or gas) located inside/outside the tubing forming coil, it is required that the steel tubing having great quality so that has sufficient capability for bearing certain pressure. Our quality control (QC) on coils could be roughly divided into two parts: Process QC and Product QC. For the former, regular expanding tests are executed depending on specified routine. The requirement for test pieces is No Failure on 20% expansion (see the following figure). For the latter, air tight test are executed on products and No Leaking is permitted for the test pieces holding certain outward test pressure.
