HDPE/PE/PP spiral corrugated pipe production line(Krah pipe making machine) 1. HDPE profiled wall winding pipe is a new type of structured wall pipe made of polyethylene, reinforced with polypropylene corrugated pipe. This type of pipe was first introduced to China from Krah Corporation, so it’s also named Krah pipe.
2. This type of pipe features light weight, high ring stiffness, easy installation, long life time and anti-corrosion. Pipe size ranges from 300mm to 800mm. this is the optimum piping for underground usage.
3. Traditionally this pipe is produced piece by piece discontinuously. Pipe length and diameter is determined by mold specification. In order to overcome this barrier, We have successfully developed a continuous production line base on winding pipe principal, which realizes online continuous production. In this way, efficiency rises and cost drops.
