Polypropylene pipe and fittings is a kind of pipe and fittings made of polypropylene (PP) material. Because of its unique physical and chemical properties, it is widely used in many fields.
Production technology
Polypropylene pipe and fittings are usually produced by two main processes: extrusion molding and injection molding.
Extrusion Suitable for the production of tubes of continuous length. After the raw materials are melted and homogenized, they are extruded by molds and then finished by cooling, sizing, cutting, and other processes. This method is suitable for large-scale production of continuous pipes, such as PPH pipes, because of its excellent chemical corrosion resistance and health safety, often used in chemical industry, food and beverage, medicine and health, water treatment, and other fields .
Injection molding is mainly used in the production of pipe fittings (such as elbows, tees, valves, etc.). The molten Polypropylene material was injected into the mold. After cooling and curing, the mold was removed and the desired shape was obtained. This method is suitable for the production of pipe fittings with complex shapes to meet the needs of different specifications and shapes.
Advantages and characteristics
1. Good high temperature and pressure resistance : Polypropylene pipe and fittings can withstand working conditions in high-temperature environments and are not easy to deform or soften, so they are widely used in hot water supply systems and industrial heating pipes .
2. Non-toxic and harmless : Polypropylene pipes are non-toxic, rust-free, and scale-free, meet water supply standards, and are suitable for food, chemical, and other fields .
3. Corrosion resistance : With excellent corrosion resistance, it can resist the erosion of chemicals and corrosive substances, and is suitable for chemical, pharmaceutical food processing, and other fields .
4. Lightweight and high strength : Compared with metal pipes, Polypropylene pipe and fittings have lighter weight and excellent strength, which is easy to install and maintain, and can reduce the load of the pipeline system .
5. Good sealing performance : With good sealing performance, it can effectively prevent leakage and ensure the safe operation of the pipeline system .
6. Long life : Because polypropylene pipes have excellent corrosion resistance and heat resistance, they have a long service life and can reduce the maintenance cost of the pipeline system .
7. Environmental protection: Polypropylene pipe is a recyclable material with good environmental performance and meets the requirements of sustainable development.
