YAOAN's corrugated pipe calibrating blocks are made of super steel after hard treatment and are processed by CNC, in which way it can guarantee the precise procession. The forming machine is of close style structure. The calibrating blocks connected like a chain are fixed on the block chain tunnel. To obtain a higher output, we can extend the calibrating block chains by increasing the NO. Of the blocks.
We could offer the whole equipment of pipe with diameter ranging from 9mm to 300mm. The corrugated pipe is suitable for the cover of cable, liquid transporting in industry, medical treatment use and so on, so it is the ideal substitute of iron pipe.
