hdpe water line pipe service life of hdpe water main pipe hdpe water line pressure rating
Standard: GB/T 13663-2000 ISO4427-1996
Material: HDPE
Color: Black pipe with blue strip
PE (polyethylene) material is widely used in the field of water supply pipe manufacturing because of its high strength, corrosion resistance and non-toxicity. Because it will not rust, it is an ideal pipe material to replace ordinary iron water supply pipe.
Pipe Features
1) Corrosion resistance: PE is inert material and can resist the erosion of various chemical media.
2) Leakage-free: It adopts electro-thermal fusion connection, hot-melt butt connection and hot-melt socket connection. Its interface strength is higher than that of the pipe body.
3) High toughness: the elongation at break is more than 500%. It has strong adaptability to uneven settlement of pipe foundation and excellent seismic performance.
4) Excellent resistance to slow crack growth (SCG) and rapid crack growth (RCP).
5) Excellent windability and scratch resistance.
6) Strong wear resistance, low friction coefficient of pipe wall, small flow resistance and strong conveying capacity.
7) A variety of trenchless methods can be adopted, which greatly facilitates the construction and installation of the work.
8) Long service life: under normal conditions, the service life can reach more than 50 years.
9) The cost of the system is low and the cost of maintenance is low, which can greatly reduce the cost of the project.
HDPE Water Pipe Main Application
1. Urban tap water pipe network system:
Large diameter HDPE pipe is health non-toxic, not fouling, more
suitable for urban water supply main conduit and buried tube,
safety, hygiene, convenient construction.
2. Replaceable cement tubes, iron pipe and steel tube: Used for old nets renovation project, don’t need large area
excavation, low cost, can be widely used in old town of pipe
network reconstruction.
3. Industrial materials duct: Chemical industry, chemical fiber, food, forestry, pharmacy, light
industry and papermaking, metallurgical and other industrial raw
material conveying pipe.
4. Landscaping water supply network: Landscaping need lots of water pipe, HDPE pipe toughness and low
cost, make it become the best choice.
5. Sewage discharge pipes: HDPE pipe have unique corrosion resistance, can be used in
industrial wastewater, sewage discharged pipe,low costs and
maintenance costs .
6. Ore, mud transfers: HDPE pipe has high resistance to stress and wear resistance, can be
widely applied in conveying ore, coal ash and river bait-casting
mud.
7. Agricultural irrigation pipe: HDPE pipe inside sleek, great flow, cross road construction, good
impact resistance, it is the ideal tool for agricultural irrigation

HDPE Water Pipe Connection
1. Material preparation: Place the pipe or fittings in a flat
position on the docking machine, leaving enough cutting allowance
of 10-20 mm.
2. Cutting: Cutting the impurities and oxide layer on the welded
pipe section and the end surface of the pipe fittings to ensure
that the two butt ends are smooth, smooth and free of impurities.
3. Alignment: The ends of two welded pipe sections should be
completely aligned. The smaller the wrong side, the better. The
wrong side should not exceed 10% of the wall thickness. Otherwise,
the quality of docking will be affected.
4. Heating: The butt temperature is generally between 210-230
degrees Celsius. The heating time of the heating plate is different
in winter and summer. The melting length of the two ends is 1-2mm.
5. Melt butting: It is the key of welding. The butting process
should always be carried out under the melt pressure. The suitable
width of crimping is 2-4 mm.
6. Cooling: Keep the docking pressure unchanged, let the interface
cool slowly, the cooling time is as long as the hand touches the
curling edge stiff, no heat is felt.
7. Completion of docking: Release the slip after cooling, remove
the docking machine, and re-prepare the next interface connection.
