PE-lined steel pipe consists of galvanized steel pipe and PE lining hose.
PE lining hose is bonded tightly to the inside wall of galvanized steel pipe under through special process
under high temperature and pressure.
This pipe has both excellent corrosion resistance of PE and
high strength of steel pipe.
The pipe can be used for potable water supply system both hot (red lining) and cool (white) liquid.
It is also applied in the transfer for some caustic flow.
For the galvanized steel pipe used, it is under the specification of BS1387-1985 Medium class.
And for the thickness of PE-lining hose, from 1/2" to 2 1/2", it is 1.5+-0.2mm, from 3" to 6", it is 2.0+-0.2mm.
The PE-lined galvanized steel pipe passes all the tests of BS6980 part II, one of the most stringent standards
on cleanliness of water pipe and can be used for drinking water supply.
The standard length is 6 meters, and special requirement on length can also be accepted.
Cold water type can be used to delivery water under 60 degree centigrade
Hot water type can be used to delivery water under 95 dgreee centigrade
Properties
1. Excellent corrosion resistance
The transported fluid and the metal layer, which is the main source of corrosion or rust,
can be separated completely and effectively. With contact only with the PE pipe,
that has excellent corrosion resistance, the water is kept fully clean and uncontaminated.
The usage life of the products is also greatly prolonged.
2. Excellent mechanical properties
The PE lined steel pipe has excellent properties characterized by the galvanized steel pipe,
such as high durability to the impact, bending and high strength.
3. High Density
The PE pipe is formed by squeezing process, material of which is high density food-hygiene standard PE.
4. Smooth fluidity
With its smooth internal surface, the fluid can run smoothly and quickly thus to avoid the block.
Package
The pipe is to be securely fastened by steel straps, with ends protected with plastic caps.
Each bundle weighs about 1.0-1.5 tons.
Application
The PE lined steel pipe inherits mechanical strength of steel pipe and corrosion resistance of PE pipe
and is widely used in plumbing system of buildings.
1. Water supply
Suitable for the pipeline system of tap water, in both residential and commercial buildings.
2. Transporting the industrial fluid
Suitable for the chemical fluid and industrial water transportation.
3. Sewage pipe line
Suitable for transporting the sewage water of city and industry.
4. Mining project
Being adopted in water supply system of mining project due to its durability to high impact.
5. Others
Other applications such as food processing, sea water transportation and air-conditioning installation.
