PVC corrugated drainage pipe large diameter drainage pipe Hebei factory spot sale

  PVC double wall corrugated pipe: PVC double wall corrugated pipe is made of UPVC as the main raw material
PVC double wall corrugated pipe is extruded from the inside and outside respectively and formed at one time
The inner wall is smooth, the outer wall is trapezoidal corrugated, and there are hollow plastic pipes between the inner and outer walls
　 
  PVC double wall corrugated pipe finished double wall corrugated pipe: PVC double wall corrugated pipe with trapezoidal hollow structure with pipe wall cut-off anchor double-layer structure, smooth inner wall and equidistant outer wall
The product has unique structure, high strength, smooth inner wall, small friction resistance and large circulation
The foundation does not need to be made of concrete foundation, with light weight, convenient handling and installation and fast construction; Rubber ring socket connection, reliable method and easy to ensure construction quality; Flexible interface
Strong resistance to uneven settlement
Double wall corrugated pipe is a successful product
The double wall corrugated pipe system meets various service needs, such as transporting drinking water: sanitary requirements, transporting gas: the highest safety requirements
Double wall corrugated pipes are classified by their ring stiffness
The ring stiffness of Sn4 and SN8 pipes is very important if they bear external loads during installation
After correct installation, the tube deflection is still very limited, but it will continue to some extent for a while
Just before it was embedded in soil, HDPE Double wall bellows behaved in & ldquo; Flexible & rdquo; The way
This means that the time in further deflection depends on the settlement of the soil around the pipe
Basically, the pipeline uses the soil movement or settlement of backfill as the technician calls it
This means that good pipe installation will lead to good soil settlement
Further deflection will still be limited
Convenient construction of double wall corrugated pipe: due to the light weight of HDPE Double wall corrugated pipe and convenient handling and connection, the construction is fast and the maintenance is simple
In the case of tight construction period and poor construction conditions, its advantages are more obvious
