Product Overview
High-modulus polypropyleneHMPP wrapped pump station materials are a plastic material currently used for underground drainage and sewage disposal, and are a relatively ideal material for wastewater systems on the market. This material has a yield strength of over 30MPA and an elastic modulus of ≥1500MPa, while the HDPE elastic modulus is only 800MPa. The material's elastic modulus plays a decisive role in the hoop stiffness of the products produced, with a higher elastic modulus resulting in a higher hoop stiffness of the product.HighModulus Polypropylene(HMPP) is used for cylinder materials due to its high crystallinity, high modulus, temperature resistance, and chemical stability, as well as excellent toughness and high impact resistance. It is a green, non-polluting, and recyclable material that does not contaminate the surrounding soil when buried.Material is corrosion-resistant, pump station available.Reutilization。
Product is based on the material characteristics
1. Temperature Resistance: HMPP has a temperature range of -20 to 90°C, outperforming HDPE in high-temperature conditions.
2. Corrosion Resistance: HMPP can withstand over 300 types of chemical corrosion, outperforming HDPE (refer to ISO/TR 10358).
3. Abrasion Resistance: HMPP > HDPE > PVC
4. Excellent hydraulic conditions: The inner wall roughness is 1/1000 of cement pipes, and the flow capacity is 1.3 times that of cement conduits.
5. This material boasts a long service life, with European market applications indicating an expected lifespan of over.
Structure and appearance
Color: Grey; inner wall can add an orange signal layer as required.;
Structure: Socket, plug, ribbed tube(Basket support + covering), consisting of sheets, with stripes perpendicular to the tube's central axis.
Production Process
The HMPP wrapped structure pump station production utilizes a secondary wrapping molding technique, which differs from the current market's Kela pipe single wrapping molding technology. In the latter, the base and ribbed pipes are wrapped onto the mold in one go, leading to drawbacks such as internal stress in the pipe material, significant deformation of the ribbed pipes, and uneven wall heights.
Secondary winding molding refers to the process of wrapping the base layer and flange of the pipe twice. First, the base layer is wrapped, followed by a thorough air-cooling process. Once the base material crystallizes, the internal material stress is fully released, and then the base surface is heated for flange wrapping. In contrast, the pipe material with one-time winding molding has internal stress, a larger deformation of the flange, and uneven shape.
Due to the direct proportionality between hoop stiffness and moment of inertia, the products of the secondary winding box process for pipes of the same specification are approximately 20% higher in hoop stiffness compared to those of the single winding process.15%-33%. In terms of cost, the HMPP wrapped pump station is even lower than the HDPE wrapped pump station model B, offering a higher cost-performance ratio.
Integrated solution for wastewater discharge issuesThe HMPP pump station is an integrated wastewater lifting pump station featuring submersible污水 pumps,格栅 gratings, and centrifugal pumps. The back pressure from the water pressure does not need to overcome the resistance of the filter screen, significantly improving the pump's efficiency. It is more energy-efficient and has lower maintenance costs than similar products. Key points to follow in the design of the integrated HMPP lifting pump station: The integrated lifting pump station is an ideal solution to replace old-style drainage pump stations and is a type of integrated lifting pump station.
IntegratedThe HMPP sewage pumping station is a newly developed product by our company, primarily designed to address locations without drainage facilities. It completely replaces traditional drainage methods such as excavation of water-filled pits and septic tanks, and the installation of sewage lifting pumps. It boasts notable "low-carbon" advantages, including low energy consumption, low pollution, and low emissions.
