Product Description
250mm UHMWPE Tube Water Pipe for cutter suction dredger
I: Discharge Pipe
Set Sail pipeline introduce :
| Ultra-high Molecular Weight Polyethylene . which refers to the molecular weight of more than 2.5 million(The common polyethylene product is about 200~300 thousand). has the development priority from China National Ministry of Science and Technology. High molecular weight give it exceptional working performance. excellent anti-abrasive. anti-corrosive.self-lubricating. impact resistant. uvioresistant. the unique low temperature resistance and good chemical stability. which is one of best of the existing engineering plastics.internationally known as the "very magical material." |

3.Feature:
| 1 | Excellent wear resistance: PE wear resistance ranks first all plastic material. 66 times than nylon. 4 times than polytef. 9 times than rdinary polyethylene. even more than ordinary metals. is 7 times than that of carbon steel. and 10 times than stainless steel. greatly improved the service life. |
| 2 | Light weight. The density PE is about 0.94g / cm3. lower than other engineering plastics. 1/2 lighter than polytef. 1/7 light of the steel pipe. thus easy for installation. reducing the energy consumption. |
| 3 | The PE pipe has good flexibility. tension. strength and elasticity. It doesn't break after folding. extruding or internal or external force impact. The pipes are connected directly and can be bended in water. The bending degree of 4 to 8 pcs of pipes can be 360 degree. It is of good resistance of storm and waves. On land, the pipes can be connected even in area with 30 degree unevenness. |
| 4 | Self-lubricating. The friction of UHMWPE is very low and good self-lubricating performance, better than other metal pipelines. |
| 5 | Chemical resistance. PE has the high chemical stability and anti-corrosive ability in the certain range of temperature and concentration ability of various of corrosive media (acids. bases. salts) and organic media. |
| 6 | Lower water absorption. PE is almost non-absorbent. does not swell in water. much less absorbent than ylon. |
| 7 | Non-stick performance. The PE surface is very weak. almost equal to PTFE. thus no scale deposit at the pipe surface. |
| 8 | Excellent impact resistance. PE has the superb impact resistance. 2 times better than polycarbonate. Even in the ammonia temperature (-269 ºC). it can still maintain good impact resistance. which make it a wide application in cryogenic engineering field. |
| 9 | Good sanitation. PE meet the national health standard. even up to the standard of human-contact field. In addition. UHMWPE also has excellent ability of cracking-resistance. electrical insulation-resistance. fatigue- resistance. deformation-resistance under high temperature. γ-rays-resistance and other superb characteristics. |

4. Application :
Floater introduce:
| The hull of floater frame is made from medium density polyethylene material with excellent flexibility. filled with high strength polyurethane foam inside. With reasonable structure and good performance. the floater becomes the ideal substitution of the traditional steel floater for the floating dredging pipes. The GI bolts and washers will be provided free. |
Floater picture:
Features:
