high density polyethylene hdpe PE liner for "groove corrosion"
Physical and chemical properties of raw materials performance and
corrosion resistance is one of the main advantages of PE material,
which makes it ideal for PE pipe as a number of areas such as
municipal water supply and drainage pipe for conveying.
1, polyethylene pipe has excellent resistance to corrosion;
2, smooth wall and the wall is not scaling with ultra-low friction,
the same diameter water pipe can be increased by 30% compared with
3, excellent wear resistance, wear resistance is 4 times the pipe;
4, trenchless situ remediation, restoration speed, long distance
5, convenient and reliable connections, no leakage risks;
6, low cost, long life; in standard conditions, the safe use of at
least five years;
7, wide application;
8, high toughness, high tensile strength, even if the pipeline is
difficult to break a serious distortion, and thus, its anti-seismic
performance is very good;
9 connection with the integration, the joint strength.
10, may be around the performance, so that tube to be changed
easily in accordance with the construction of tracks.
11, good resistance to rapid crack pass
Repair of HDPE pipe lining the mechanism of pipeline technology:
the use of HDPE material has shape memory characteristics, in the
HDPE liner into the pipe to be repaired before the cross-sectional
area will reduce the HDPE liner, the liner pipe penetration, the
use of heat or pressure method to activate the memory of HDPE, the
HDPE liner back to the original diameter, so that management can
increase wear and reduce the distance the number of joints, but
also reduce the HDPE liner in the pipeline transport Wear. Select
slightly larger than the diameter of pipe liner diameter, shape
recovery after the expansion of HDPE liner attached to the pipe
wall, forming the lining of excellent performance. Steel pipe to be
repaired to protect the lining of the HDPE pipe objects outside the
tube is not crushed or punctured, but also to prevent the media
from being transported within the HDPE liner pipe bursting; and
HDPE liner will be the transmission medium and to be repaired Pipe
separated to prevent corrosion of the media, ultimately the purpose
of pipeline repair and corrosion, the formation of anti-corrosion
performance of HDPE mechanical properties of metals combined with a
1, for various caliber seamless steel pipe and repair;
2, the internal corrosion of drinking water pipelines and pipeline
3, sand high flow speed, on the bottom line, "groove corrosion"
4, scaling serious infusion capacity of the pipeline, after
clearing debris interspersed within the HDPE pipe, to prevent
scaling. Crude oil production plant, water, gas and solid
multiphase pipeline. Due to the wear resistance of HDPE pipe is 4
times higher than steel, oil production plant for the sewage
pipeline corrosion (internal corrosion on the pipeline of new and
old pipe rehabilitation).
