Interlock Pipe
20≤DN≤385 MM
Interlock pipe is made of stainless steel which entwined, all the processes in one production line. Although the production process is simple, the interlock pipe has a big function. The Pipe is softness, small reaction force when bending, well seismic performance, easy install. These merits make interlock pipe be more popular. Used in the composite flexible body to reduce flow resistance, it can be the outside cover layer to prevent the hose extreme bending when work. Or used for the exhaust system as the exhaust pipe. Whether in its use, or in installing, the interlock pipe all has advantage.
