Product Description
HDPE Pipes intended for drainage and sewer under pressure shall be black with brown stripes. and features a service life of 70 years, making it the ideal, low-maintenance investment for any municipal or private sewer owner.
HDPE Drainage Pipe Black With Brown Stripes Introduction
HDPE stands for High-Density Polyethylene, which is a plastic piping material especially suitable for drainage and wastewater applications. Black With Brown Stripes is a common color for HDPE drainage pipe, but it is also available in other colors such as HDPE Drainage Pipe Black With Blue Stripes, HDPE Co-Extrusion Drainage Pipe, and so on. Blue Stripes, HDPE Co-Extrusion Drainage Pipe, and so on, are usually chosen according to the project requirements, or other colors can be customized according to the customer’s needs.
Advantages
HDPE drainage pipe offers many benefits, including resistance to corrosion, and chemicals, lightweight, impact, abrasion, and ease of installation and maintenance. It is commonly used in municipal drainage systems, stormwater drainage, sewage treatment, agricultural drainage, and other drainage applications.
HDPE Drainage Pipe Black With Brown Stripes Production process
- Selection and preparation of raw materials: First of all, high-quality HDPE resin needs to be selected as raw material. Moisture and impurities in the raw material need to be removed to prevent air bubbles and degradation of pipe properties during the production process. Depending on the demand, additives such as antioxidants, UV stabilizers, color masterbatches, and other additives may also need to be added to improve the performance and appearance of the pipe.
- Mixing and Plasticizing: Use efficient mixing equipment to mix the raw materials and additives evenly. After mixing, the raw materials are 3. heated and melted in the plasticizer to reach the flow state for subsequent extrusion and molding operations.
- Extrusion molding: The raw material in the molten state is extruded into a tube shape by means of an extruder. This process requires precise control of the die temperature and molding pressure to ensure the cooling rate and molding quality of the pipe. The design of the mold also affects the shape and dimensional accuracy of the pipe.
- Cooling and molding: The extruded tubes need to be rapidly cooled by a cooling device to allow them to cure quickly. The cooling method can be water-cooled or air-cooled, and the specific choice depends on the thickness of the pipe and the production efficiency. Control of cooling time and temperature is critical to ensure the strength and stability of the pipe.
- Cutting and Straightening: The cooled tubes need to be cut to obtain the required length of tubing. At the same time, the pipe needs to be straightened by a straightening machine to ensure its straightness in appearance.
- Quality Inspection: During the production process, several quality inspections are required to ensure that the quality of the fittings meets the standards. This includes appearance inspection, size measurement, pressure test, etc.
