Traditional Composite Pipes (Lap Wielding)

Seamless Butt Wielding Pipes

 lap welding by ultrasonic wave, fusion jointing in surface, with clearance, not close.

lap welding by ultrasonic wave, fusion jointing in surface, with clearance, not close.

butt welding with aluminous belt, welding line easement, even thickness of pipe,  smooth.

overlapped aluminum belt, unable to conduct welding line spot checking, cannot know leak in welding.

butt welding with aluminum belt, can check welding line in working; if leak in welding occurs, it is automatically cut.

thick in thickness so it is higher than traditional aluminum plastic pipe in bearing force.

co-extrude  with one step, because internal pipe does not harden in process so it is easy to get eccentric.

 for each layer extrude with two steps, pipe dimension is high in accuracy and the pipe is in good quality.
