Product Overview

High modulus polypropylene HMPP winding station material is a plastic material currently used for buried drainage and sewage treatment, and is 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 elastic modulus of HDPE is only 800MPa. The elastic modulus of the material plays a decisive role in the hoop stiffness of the products produced, with a higher elastic modulus resulting in higher hoop stiffness of the product.HighHigh Modulus Polypropylene (HMPP) is used for cylinder material, offering high crystallinity, modulus, temperature resistance, and chemical stability, along with excellent toughness and high impact resistance. It is a green, non-polluting, and recyclable material, ensuring no soil contamination from landfill use.Material is corrosion-resistant; pump station is available.Reclamation。

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 channels.

5. This material boasts an excellent long-term lifespan, with feedback from the European market indicating an expected service life of over.

Structure and Appearance

Color: Grey, with the option to add an orange signal layer to the inner wall as required.

Structure: Composed of the socket, plug, ribbed tube (support basket + covering), and base plate, with stripes running vertically along the central axis of the tube material.

Production Process

The HMPP Spiral Structure Wall Pump Station is produced using a secondary winding molding technique, which differs from the current market's KRAHNE single winding molding technology, where the base and ribbed tubes are wrapped onto the mold in one go. This method has the drawback of internal stress in the pipe material, significant deformation of the ribbed tubes, and uneven wall heights.

The double winding molding process involves wrapping the base layer and flange of the pipe in two stages. First, the base layer is wrapped, followed by a thorough cooling process. Once the base material has crystallized and the internal stresses are fully released, the base surface is then heated for the flange wrapping. In contrast, single-winding molded pipes have internal stresses, with a significant deformation of the flange and uneven cross-section.

Due to the direct proportionality between hoop stiffness and moment of inertia, the hoop stiffness of the products from the secondary winding box process is approximately 15%-33% higher than that of the products from the primary winding process for pipes of the same specification. In terms of cost, the HMPP winding pump station is even lower than the HDPE winding pump station model B, offering a higher cost-performance ratio.

An integrated HMPP pumping station for wastewater treatment, featuring submersible pumps, grates, and centrifugal pumps, significantly enhances pump efficiency as the back pressure from water pressure does not need to overcome the resistance of the filter mesh. This model offers greater energy savings and lower maintenance costs compared to similar products. Key points to consider in the design of an integrated HMPP lifting pump station: The integrated lifting pump station is an ideal solution to replace outdated drainage pump stations, being a modular and integrated lifting pump station.

The Integrated HMPP Sewage Pump Station is a newly developed sewage lifting pump station product from our company, primarily designed to address situations without drainage facilities, fully replacing the traditional methods of digging ditches and septic tanks, and setting up drainage systems with sewage lifting pumps. It boasts significant "low-carbon" advantages such as low energy consumption, low pollution, and low emissions.
