The coil made of a single tube, no welding connection, which reduces the leakage possibility.

For solar energy

The water in the solar water tank can not be used directly because the heating time is too long and the water quality is polluted. Therefore, through the built-in heat exchange stainless steel coil in the solar water tank, the heat of the high temperature water in the tank is transferred to the clean water flowing through the tube coil. So people can use clean, hot tap water.

Stainless steel tube coil is usually used for heat exchanging, ie, different media (liquid or gas) inside and outside of the tube are to carry out heat exchanging. So the tube coil must be strong enough to withstand a certain high pressure and high temperature. And so the quality of tube coil is very important.
Our quality control are mainly making process control and finished coil quality control. In the making process, flaring tests are regularly carried out, the tube is expanded by more than 20%, and no cracks shall be happen. For finished tube coil, air tightness tests are carried out at requested pressure, no leakage allowed.
