PE-100/PE4710 GAS PIPE |
|
Endot announces the immediate
availability of PE-100/PE4710* gas pipe produced from the new, high
performance Bi-Modal resin, DGDA 2490BK from Dow Chemical.
Endot PE-100/PE 4710 Gas Pipe is produced in black with three yellow
stripes for easy identification as gas service pipe and tubing.
Endot PE-100/PE 3408 Gas Pipe is available in CTS and IPS dimensions
produced to ASTM D2513 and is available in sizes from ½”
through 8 ”.
The Dow resin DGDA 2490BK used to make Endot PE-100/PE 4710 Gas
Pipe is a Bi-Modal, High Density Polyethylene (HDPE) and is the
first ISO PE100 pipe material produced in North America to be listed
with a 100- year rating at 20°C (68°F) by The Plastics Pipe
Institute, Inc. (PPI). DOW DGDA-2490 BK100 HDPE resin also was given
a 50-year rating at 40°C (104°F) and an 11-year rating at
60°C (140°F) by the PPI, making it the first PE100 resin
to be listed at elevated temperatures
This new HDPE resin provides
enhanced performance characteristics, such as:
- Superior Slow Crack Growth (SCG)
resistance
- Excellent resistance to Rapid Crack Propagation
(RCP)
- High temperature/pressure performance
- Increased toughness (especially at low
temperatures)
- Increased tensile strength and modulus
- Enhanced fusion to MDPE and other HDPE
pipe grades
