sand dredge pipe

1.deliver sand ,slurry 2..excellent mechanical properties 3.excellent wear resistance 4small flow resistance

sand dredge pipe adopt UHMWPE material as the matrix by unique technology processing. It possess many superior qualities over other kind of mine used pipe. 

1, excellent mechanical properties

The strength capacity and impact resistance of common PE pipe is 13-16mpa and 10 kj/m²respectively. Compared with UHMWPE pipe for mine the streght capacity and impact resistance is no less than 25mpa and 70 kj/m² around. In view of the good properties, it will be more secure long-term use.

2, excellent wear resistance

Because our product adopt UHMWPE as the matrix, the wear resistance is 3 times higher than common mine used polyethylene pipe. Our product is more favourable for the slurry transportation.

3. small flow resistance

The pipe wall is smooth and the index of friction is small so in the same circulation rate the outer diameter of UHMWPE pipe is about 15% smaller than steel pipe.

4. flame-retardant and anti-static performance stable

The product apply special coupling agent to antistatic and using flame retardant agent to make the surface activative, enable it forms "molecular bridge" with resin matrix,  and merges each other as one. This technology noly need a small amount of addition to get a good double-antibody result.

5, flange connection is more reliable

Interface with the natural mother flanging getting by rolling up both end of pipes, can bear shockes. And welded joints cracking or interface spliting can be avoided.
