           DN160 Coal Mining Steel reinforced HDPE Pipes 


Quality assurance:

Donghong Brand steel reinforced PE mining pipe has good physical property and long-term hydrostatic strength. It is the first to get the certificate of 3.5Mpa Coal Mining Safety Mark of China. Its service life can reach over 50 years.


Carried standard: 



Advantages: compare with HDPE pipe

1.  Much more higher Pressures Borne, Lower Costs than same pressure HDPE Pipe.

2.  The pipe not only combines the advantages of plastic and steel pipes but also eliminates their disadvantages such as lower pressure resistance for plastic pipe and rustiness for steel pipe.  

Raw Materials: 100% Prime Grade HDPE Resin, High Strength Adhesives and Steel Wires.Special performance: fire retardant and antistatic Applications: mainly used in underground coal mines for drainage, ventilation, coal slurry delivery, gas drainage and so on.Connection: Socket fusion, electrofusion connection, flange connection, quick coupling. Colors: black or other colors on customers’ requirementsSize range: from 50mm to 630mmPressure rating: 0.8Mpa--1.0Mpa--1.25Mpa--1.6Mpa--2.0Mpa--2.5Mpa--3.5Mpa--4.0Mpa--5.0MpaWorking life: More than 50 years under normal conditionsCarried standards: CJ/T189-2007 & MT181

Manufacturing process:

Step1: Extrusion of core tube

Step2: Wrap spirally steel wire on the core tube in left direction

Step3: Wrap spirally steel wire on the core tube in right direction

Step4: Coat with additional adhesive layer to cover the steel wire mesh and let it combined with core layer and outer PE layer

Step5: Extrusion forming


Performance and characteristics:

1. Light weight, long service life, easy installation

Its weight is lighter, while its service life is 8-10 times more than steel pipe.

2. Good anti-corrosion property, high pressure resistance, superior mechanical property.

3. Low noise in media transportation.

4. Good sealing.

No leakage after pressure testing

5. Easy installation

6. Excellent flame-resisting and antistatic performance

Both fire resistant and antistatic performances meet the national standard.  It can be used in inflammable and explosive dangerous place.
