Yongcheng 700 steel belt polyethylene bellows

  Steel belt corrugated pipe is a kind of reinforced pipe formed by melting HDPE and steel belt
The product implements the national cj/t standard
The pipe wall structure is composed of three levels
It takes the spiral wound high-strength steel belt as the reinforcement, takes the high-density polyethylene as the matrix, and adopts a unique manufacturing process to integrate the steel belt and high-density polyethylene, so that it has both the flexibility of plastic pipe and the rigidity of metal pipe
The ring stiffness reaches sn16, which is suitable for large Deep municipal engineering applications
Society is developing and the country is building, so now there are many large and small projects being implemented
The implementation of projects requires a lot of pipelines, and the need for drainage and sewage pipes is great
Therefore, there are many kinds of pipelines now, and there will be many problems in choosing pipelines
Because you don't know the pipeline industry very well, sometimes you don't know what kind of pipelines your engineers need
In current projects, Many customers choose HDPE Double wall corrugated pipe and steel belt reinforced polyethylene spiral corrugated pipe
But these two kinds of pipelines are different
Some customers will ask, so what are the differences between these two pipelines?
We have made a professional investigation
There are many differences between HDPE Double wall corrugated pipe and steel belt reinforced polyethylene spiral corrugated pipe, but the first thing to understand is that their similarities are the drainage and sewage pipes, and that their materials are the same, both of which are high concentration polyethylene, and that they are corrugated
Therefore, we see their common ground, below, Let's learn about their differences:
  First, from the literal meaning, these are two different pipes, one is called corrugated pipe, and the other is called spiral corrugated pipe, so there are also differences in the production;
  Second, they are all corrugated, but the things in the corrugated are different
The HDPE Double wall corrugated pipe is empty in the corrugated, and the steel strip reinforced polyethylene spiral corrugated pipe has steel strip
The steel strip melts with polyethylene in the molten state to form a close bond
So the pressure resistance is very strong;
Third, the production time of these two kinds of pipes is different
The relative time of double wall bellows is shorter, so the production of pipes is very high, and there is no waiting for goods

Precautions for installation of steel belt bellows:
  In the process of general pipe laying, many construction units directly use bulldozers to bury the soil mixed with construction waste into the pipe trench after laying the pipes
This is incorrect and will cause great damage to the pipes
Now, please follow the following construction methods

  First of all, the material of double wall bellows is light, so it is necessary to ensure that the pipeline does not float during the construction period
Secondly, the compactness of pipe bottom cushion and backfill determines “ Pipe and soil ” The load capacity of the system and the radial deformation rate of the tube should reach “ Pipe soil interaction ” The compactness of pipe bottom cushion and backfill must meet the design requirements
To achieve the above two points, it is necessary to ensure that there is no ponding in the trench during backfilling, no backfilling with water, no backfilling with silt and organic matter, and the backfill shall not contain stones, bricks and other miscellaneous hard objects; For places with high groundwater, the groundwater level should drop below the di point at the bottom of the tank, and the lowering of groundwater can be stopped only when the project is not affected by groundwater or the foundation strength and pipeline anti floating are met
