Kaifeng 500 steel strip polyethylene bellows

  The steel belt reinforced polyethylene (HDPE) spiral corrugated pipe for buried drainage is pressed into an approximate U-shaped spiral steel rib with continuous steel belt and wound between the inner and outer two layers of hot-melt polyethylene, combining the high rigidity and strength of steel with the flexibility, corrosion resistance and wear resistance of polyethylene
While achieving high performance, the outstanding advantage of steel belt corrugated pipe is to save raw materials, which can significantly reduce the cost compared with all plastic buried drainage pipes with the same diameter and ring stiffness

Steel belt reinforced polyethylene (PE) spiral bellows: DN300, dn400, DN500, DN600, DN700, DN800, dn900, DN1000, DN1100, DN1200, dn1300, dn1400, DN1500, DN1600, DN1800, DN2000, dn2200, DN2400, DN2600, dn3000, steel belt reinforced polyethylene (PE) spiral bellows can produce 3M diameter

Steel belt reinforced bellows
1
The steel belt reinforced bellows produced by Guorun new material has passed the ISO9001:2000 quality system certification, and the product quality price ratio is higher

2
The steel belt reinforced bellows adopts the domestic advanced steel belt reinforced bellows production line and forming process, and the special materials are used to solve the problem of steel plate corrosion prevention

3
The diameter of steel belt reinforced corrugated pipe ranges from dn300mm to dn3000mm
There are 18 specifications and more than 50 models of steel belt reinforced corrugated pipe, with more complete specifications

4
HDPE Double wall corrugated pipe, double wall corrugated pipe, steel belt reinforced corrugated pipe, the whole line of products, better service

5
Long service life of steel belt reinforced bellows: the normal service life can reach more than 50 years

6、“ Professional management and integrity ” The purpose is to greatly improve the reputation of the enterprise, and the market of steel belt reinforced bellows products is expanding rapidly

 
Physical and mechanical properties of steel belt reinforced spiral bellows:
1
Large diameter and high strength: due to the use of U-shaped steel strip composite PE material, the ring stiffness of the pipe is greatly improved without increasing the cost, and the strength is greatly improved compared with other plastic drainage pipes under the same weight
It can solve a series of problems such as heavy load, and the advantages of large-diameter pipes are more obvious, which are lighter and stronger than cement pipes and other plastic pipes

2
Stable performance: the composite of each layer is carried out in the molten state of plastic; Therefore, the composite fastness of each layer bonding is very reliable and the product performance is stable

3
Long corrosion resistance life: the steel strip surface is specially pretreated by high-tech means to enhance the corrosion resistance of steel and the adhesion between steel and plastic, and improve the peel strength
When the plastic raw materials are fully molten, the overall structure of the pipe is firm and reliable
The use of special materials and processes not only solves the problem of steel plate corrosion prevention, but also solves the adhesion between steel plate and PE material, so that the service life of the pipeline is the same as that of pure plastic pipeline, which is guaranteed to be more than 50 years

4
Various connection methods and reliable connection: it can be connected by electrothermal fusion, heat shrinkable belt, internal and external extrusion welding or a combination of various connections, and the connection is firm
Reliable connection can make the pipeline achieve zero leakage

Quality assurance:
Details determine success or failure
Through every detail, Guorun new material products show an outstanding style; Such high-quality charm quality benefits from excellent production equipment, scientific process formula and strict quality assurance system

 
Quality requirements for steel belt reinforced bellows:
1
Safety and reliability
This is an important principle of Zui
Pipes should be able to withstand vibration and shock, water hammer, thermal expansion and cold contraction, and withstand the test of time, without water leakage and bursting

2
Hygiene
Obviously, the pipes that are currently on the market must meet the requirements of the national standard cj/t225-2011, and can only be put on the market after passing the test by the nationally recognized testing department
　　
3
Energy saving
Any pipe will consume energy from raw material refining and synthesis, cadmium melting, rolling and injection extrusion
From a macro point of view, metal pipes consume more energy than HDPE steel strip reinforced polyethylene pipes
In the composite process, the steel plastic composite pipe with thermal expansion and spraying composite process consumes more energy than the metal pipe, and the thick wall pipe consumes more energy than the thin wall pipe

4
Economy
On the premise of meeting the use safety, HDPE steel strip reinforced polyethylene pipe shall be used at least
When comparing the prices of pipes, we should also compare the prices of pipe fittings and the construction and installation costs

5
Sustainable development
The important reason why any kind of pipe can be used by people without aging is that it can be recycled and reused without new pollution

What should be paid attention to in the construction of steel belt reinforced bellows
1
During installation, attention should be paid to protection to avoid mechanical damage
After installation, the location of the pipeline should be marked, so that if the second decoration is to avoid damage

2
Because the steel belt reinforced spiral bellows is not resistant to low temperature, avoid knocking during installation in winter
When cutting the pipe, use a sharp knife to cut it slowly, and take warm measures if necessary

3
When installed outdoors or in direct sunlight, a dark protective layer shall be wrapped

4
Technical measures must be taken to prevent the expansion and deformation of the pipeline when laying pipes in the open or non directly buried way

5
After the pipe is installed, the pressure test must be carried out before sealing the pipe (directly buried) and covering the decorative layer (non directly buried concealed laying)

  The steel belt bellows is selected from Luoyang Guorun New Material Technology Co
, Ltd
The steel belt bellows produced by Guorun new material has a diameter range of 300-3000 mm and a length of 6-10 meters
The ring stiffness can reach SN8, Sn10, sn12
5 and sn16
It makes up for the limitation that the general ring stiffness of large-diameter plastic buried drainage pipes can only reach SN8 in the past
It has the characteristics of corrosion resistance, aging resistance, wear resistance, light weight, convenient connection and so on
It is widely used in municipal drainage, building sewage discharge, water transmission and water supply
