Grade:Hot Water
Product:With The Inner Stainless steel Ring Plastic-Steel Composite
Panel for Hot Water
Decriptions
With the inner stainless steel ring plastic-steel composite panel
is combination with PEX pipe and Hot dip galvanized steel pipe and
the inner stainless steel ring. It is used by constant pressure and
high temperature composite technology,ensure the inner plastic pipe
in good shape and bonding the steel pipe well,without glue cracking
and shrinking issues happening.
The hot DIP galvanized steel pipe is adopt the international
leading high-frequency new welding technology,and galvanized with
high quality 0 pure Zinc plating. The plastic pipe is used by high
quality and 100% virgin PE,which meets the standards of food hygiene and drinking water.
The hot melt adhesive resins are good quality,high purity with
excellent bonding strength,ensure the bonding strength between the
steel pipe and plastic pipe. The plastic-steel composite pipe head
is fixed the inner 304 stainless steel ring,which is national
patent products. The inner stainless steel ring perfect resolves
the separated problems between the plastic pipe and steel pipe,for
which the expansion and contraction happens, or the flow water
impacting the pipe head for long time.
The revolutionary technology can protect the water quality
well,meanwhile elongates the pipe service life greatly and makes
price competition. The big size pipes form DN-200 to DN400 are used
by same technology as small size pipes, which is hard to achieve by
most of other companies.

Application
Water supply pipe system for domestic water,drinking water and
projects,other relevant fields.
Advantages
1. High mechanical strength. The inner solid ring steel-plastic
composite pipe has the same excellent mechanical strength as the
hot-dip galvanized steel pipe. It has strong resistance to impact,
bending and pressure, and the operating pressure range is less than
or equal to 1.6Mpa.
2. Anti-corrosion and long service life. The conveying fluid is
effectively isolated from the metal, only in contact with the
plastic layer, and has a good anti-corrosion effect, which greatly
prolongs the service life of the pipeline, and can be used for 70
years under normal conditions.
3. The fluid resistance is small. The inner wall of the
steel-plastic composite pipe with inner solid ring is smooth, the
friction coefficient is small, the flow rate is fast, no scale is
accumulated, and the fluid resistance is small.
4. Good hygiene performance. The lined plastic pipe is made of
food-grade plastic, brand-virgin PEX, which will not pollute
the conveyed medium, the inner wall is smooth, free of scale and
rust, ensuring that the water quality and sanitation indicators
meet the domestic water transmission and distribution standards,
and the quality reaches international quality level.
5. Plastic and steel pipe are well compounded. Strong adhesion, not
easy to fall off, good sealing performance, no pinholes or cracks
to ensure no leakage.
6. The plastic layer has good performance. Low thermal
conductivity, environmental protection and energy saving, good low
temperature brittleness, and small expansion coefficient.
7. Simple installation. The traditional installation process, and
the use of matching pipe fittings with strong sealing energy
absorption, the connection is reliable, simple and fast. The
pipeline is easy to maintain and the maintenance cost is low.
8. The main equipment is self-developed and has the characteristics
and professional technology that ordinary enterprises cannot
imitate. The production efficiency and production capacity are 3-5
times that of general enterprises. The lead time required by
customers can be ensured.
