Innovative HF Welding Technology

DOOWIN pillow tanks use HF welding technology. The HF welding seams have better tensile strength than the hot-air welding seams. It has more stable performance, not easy to separate for long term storage.

Traditional Hot-Air Welding Technology

We abandon the traditional hot-air welding technology. The hot-air welding seams are not persistent. The seam is easy to seperate. Some inferior bladders prefer this welding.
