HDPE storm pipe is mainly used in rainwater drainage systems. It is an application of HDPE Drainage Pipe, which has excellent pressure resistance and corrosion resistance. It can be used to replace traditional cast iron pipes as rainwater drainage pipes.
HDPE storm pipe function
HDPE storm pipe is a high-density polyethylene water pipe made of high-density polyethylene as the main raw material through extrusion molding. It can not only be used for rainwater drainage but also for various drainage occasions, including but not limited to farmland irrigation and sewage discharge. It has become the leader in drainage pipes and can replace steel pipes or PVC drainage pipes. It is used in tunnels, underground tunnels, municipal engineering, water intake plants, garbage plants, and other places where drainage is required, as well as in the drainage of green spaces in parks.
Production process
1. Raw material selection and processing: Select high-quality high-density polyethylene (HDPE) resin as raw material, and carry out corresponding processing according to production requirements. This includes storage management of raw materials, keeping the raw materials dry and clean, and preventing moisture and pollution.
2. Batching and mixing: Determine the batching ratio of HDPE and other additives according to production needs. Use efficient mixing equipment to ensure that the raw materials are evenly mixed without impurities and bubbles.
3. Plasticization and extrusion: Heat the mixed raw materials to the plasticized state to make them flow. Then, the plasticized raw materials are continuously and evenly extruded through the extruder to form the basic shape of the pipe.
4. Molding and cooling: Use a special molding mold to ensure that the shape and size of the pipe meet the standards. At the same time, through appropriate cooling methods, the pipe is quickly cooled and shaped to maintain a stable shape.
5. Inspection and trimming: The quality of the produced HDPE storm pipe is inspected, including the testing of indicators such as size and pressure. For unqualified pipes, they are trimmed or scrapped.
Product advantages
1. High strength: HDPE storm pipe has high tensile strength and compressive strength, and can withstand large water pressure and groundwater level pressure.
2. Corrosion resistance: It has excellent corrosion resistance and can be used for a long time in harsh environments such as acid, alkali, and salt water without corrosion.
3. Environmental protection: It is an environmentally friendly pipe material that does not contain toxic substances and will not pollute the environment.
4. Easy installation: It has light dead weight and flexibility, and is easy and quick to install, saving construction time and cost.
Installation steps
1. Determine the direction and burial depth of the pipeline: According to the design requirements and actual conditions, determine the direction and burial depth of the pipeline for subsequent construction.
2. Dig trenches: Dig trenches according to the direction and burial depth of the pipeline to ensure that the width and depth of the trench meet the requirements.
3. Lay pipelines: Lay HDPE storm pipes in the trenches, pay attention to the connection method of the pipelines and the installation of connectors.
4. Fill and tamp: Fill soil on both sides of the pipeline and tamp the soil to ensure the stability and density of the pipeline.
5. Install inspection wells: Install inspection wells at the turns and branches of the pipeline as needed to facilitate pipeline inspection and cleaning.
6. Perform pressure test: After the pipeline is installed, perform pressure test to check the pipeline’s sealing and pressure bearing capacity.
