Application of HDPE Double Wall Corrugated Pipe in Rural Domestic Sewage Treatment
The treatment of rural domestic sewage is an important measure to improve the rural human settlement environment, which is of great significance for improving the rural living environment and creating a new countryside with green waters and green mountains.
At present, the rural domestic sewage treatment project is in full swing, and several effective models have been explored in the process of treatment and transformation. The first mode is that the sewage is brought into the municipal sewage pipe network through the pipe network and treated by the municipal sewage treatment station; The second mode is to collect the sewage through the pipe network, build a village level integrated sewage treatment point nearby, and return the treated sewage to farmland on site after reaching the standard; Mode 3 is to adopt household level integrated sewage treatment equipment, one household one treatment.
No matter which mode is adopted for sewage treatment, the sewage drainage pipe plays an irreplaceable role. The domestic sewage of every household is collected through the sewage drainage pipe, collected into the sewage treatment station for treatment, and discharged after reaching the standard.
Sewage drainage pipes include concrete pipe, cast iron drainage pipe, FRP sand pipe, HDPE winding pipe, HDPE Double wall corrugated pipe and so on.
Corrugated Pipe
Among them, HDPE Double wall corrugated pipe is an excellent choice for drainage pipes used in rural domestic sewage treatment projects because of its large production capacity, smooth inner wall, flexible connection, no leakage, portability, easy construction and low cost.
HDPE Double wall corrugated pipe is a new light pipe with annular corrugated structure outer wall and smooth inner wall produced from low-pressure polyethylene (HDPE). It has the characteristics of light weight, good toughness, fast construction and long service life.
Double wall corrugated pipe has excellent pipe wall structure design, which greatly reduces the cost compared with other isotropic pipes, convenient construction and connection, corrosion aging resistance and no leakage. It has been widely used at home and abroad, replacing a large number of concrete pipes and cast iron pipes.
Executive Standard
GB / T 19472.1-2019 polyethylene (PE) structural wall piping systems for underground use Part 1: Polyethylene double wall corrugated pipe
Product Features
High ring stiffness: the outer wall has an annular corrugated structure, which greatly enhances the ring stiffness of the pipe and has obvious advantages compared with other pipes.
Material cost saving: under the condition of the same ring stiffness, about half of the raw materials can be saved compared with the solid wall pipe, which greatly saves the material cost.
Anti settlement: it can be slightly flexed in the axial direction and is not affected by a certain degree of uneven settlement of the ground.
Fast construction: light weight, flexible socket connection with rubber ring, fast construction and simple maintenance.
Application Fields:
-
Municipal Engineering: used as drainage and sewage pipe.
-
Construction works: used as rainwater pipe, underground drainage pipe, sewage pipe and ventilation pipe of buildings.
-

-
Perforated double wall corrugated pipe: it can be used as seepage and drainage pipe of saline alkali land expressway.
Installation Instructions for HDPE Double-wall Corrugated Pipe
First, when receiving HDPE Double wall bellows, be sure to check whether the pipe material is damaged. If damaged, cut off the damaged part in time.
HDPE Double wall corrugated pipe is generally connected by rubber ring socket, and the rubber ring is used to ensure the firmness of the pipe.
When the HDPE Double wall bellows is connected, a hydrostatic test shall be conducted to confirm that there is no leakage, and the test pressure shall be 1.5 times of the design pressure.
The pipe quality shall be inspected in strict accordance with the executive standard of HDPE Double wall corrugated pipe. The applicable executive standard of HDPE Double wall corrugated pipe is GB / t19472.1-2019 polyethylene (PE) structural wall piping system for underground use Part 1: Polyethylene double wall corrugated pipe
As HDPE Double wall corrugated pipe is a plastic pipe, it shall not be exposed to high-temperature open fire or long-term exposure to rain.
HDPE double-wall corrugated pipe is a plastic environmental protection pipe with polyethylene as the main material. It is widely used in drainage piping systems. Madisonpipe reminds you that you must strictly require the quality of HDPE double-wall corrugated pipe, safe workmanship, and safety.
