Polyethylene pipe PE100\PE80 for underground coal mine
The polyethylene pipe used in coal mine is a single-layer solid wall pipe, which is produced by carbon nanotube (CNT) modified material with independent intellectual property rights of our company. The addition amount of highly conductive fiber carbon nano (CNT) instead of the traditional carbon black conductive agent is only 30% of the carbon black conductive agent, and the antistatic and flame retardant performance is better than the MT181 standard requirements. And the performance indexes are higher than the traditional carbon black conductive pipeline. In particular, the long-term hydrostatic performance of the pipeline is much higher than that of traditional products, and the pipeline system has better safety and long-term usability

1hydraulic testAccording to MT558.1-2005 test conditions, PE80 level circumferential stress 9.0MPa. PE100 grade circumferential stress 12.0MPa, pressure preservation 100h, no rupture, no leakage.
2Negative pressure resistanceUnder the negative pressure of 0.097MPa, the pressure should be maintained for 100h, and there should be no sucking and damage.
3Flat propertyWhen the pipe is pressed to coincide with the inner wall, there should be no cracks and damage
4Drop weight impact test

According to MT558.1-2005 test conditions, 9 out of 10 samples should have no cracks and Destroy.

5Elongation at breakIt should not be less than 300%
6Note: The properties of the above pipes are unified requirements, and relevant standards shall be implemented for detailed performance. Negative pressure resistance is only for negative pressure gas extraction pipe.
