PPH pipe (alloy polypropylene pipe) is a β modification of ordinary PP material, so that it has a uniform and delicate Beta crystal structure, with excellent chemical corrosion resistance, wear resistance, good insulation, high temperature resistance, working temperature can reach 100 °C, non-toxic, light weight, easy to transport and install, this is a high-quality product with high temperature resistance, corrosion resistance and aging resistance than PP pipe.
Material characteristics
- Chemical resistance—– Of all polypropylene tubing, experiments have shown that (β)-PPH tubing has the strongest chemical resistance.
- Long life—– Beta-(β)-PPH duct has a longer service life and higher system safety.
- Impact Strength —– Compared with the traditional (α)-PPH tube, the (β)-PPH tube has significant low temperature impact strength.
- Temperature resistance—– (β)-PP-H pipes are suitable for temperature ranges from -20°C to 110°C according to the actual application.
- Pressure-resistant —– (β)-PPH pipe has the highest pressure resistance (MRS10) of all polypropylene materials used in piping systems.
- The high-performance —– (β)-PP-H pipe has excellent performance, flexible welding equipment and professional technical support team can not only ensure the welding and installation quality of (β)-PP-H pipe system, but also provide customers with customized processing of non-standard products according to their needs.
Areas of application of PPH
- Packaging industry: Because PPH material is non-toxic and tasteless, and has good thermal stability and moisture resistance, it is often used in the packaging of food, medicine and other products.
- Automotive industry: The impact and corrosion resistance of PPH makes it an ideal material for automotive interior and exterior trim parts, such as bumpers, instrument panels, etc.
- Home appliances: PPH materials are also often used in the shells and components of household appliances such as washing machines and refrigerators, because it can not only meet the strength requirements, but also have aesthetics.
- Medical industry: PPH is also used in the manufacture of medical devices and containers due to its biocompatibility and chemical stability.
- Piping system: PPH pipes are widely used in chemical industry, water supply, drainage and other fields because of their corrosion resistance, high strength and long life.
Storage methods and precautions
- Avoid direct sunlight: PPH pipes should be kept out of direct sunlight during storage to avoid material aging. Choose a cool and ventilated warehouse for storage, and ensure that the temperature in the warehouse is appropriate.
- Prevent moisture: PPH pipes should be avoided from moisture during storage to avoid deformation of the material due to moisture. Ensure that the humidity in the warehouse is moderate, and take moisture-proof measures, such as laying moisture-proof mats, etc.
- Classified storage: PPH pipes of different specifications and models should be stored separately to avoid confusion. During storage, the pipes should be avoided from crushing or colliding with each other to avoid damage to the pipes. For pipes below DN25, they can be bundled, and the length of each bundle should be consistent, and the weight should not exceed 50Kg; Pipe fittings should be packed separately according to different varieties and specifications.
- Stacking requirements: PPH pipes should be stacked horizontally on flat cushions, the width of the cushions should not be less than 75mm, the spacing should not be more than 1m, the overhang at both ends of the pipe should not exceed 0.5m, and the stacking height should not exceed 1.5m. The pipe fittings should be stacked layer by layer, and should not be stacked too high.
- Avoid contact with chemical substances: During storage, contact between the pipeline and chemical substances such as acids and alkalis should be avoided to avoid chemical reactions affecting the quality of the pipeline.
- Regular inspection: Regularly inspect the stored PPH pipes, including whether the appearance is intact, whether there is deformation, etc. If problems are found, they should be dealt with in time to ensure the quality of the pipes.
- Keep away from heat sources and fires: PPH pipes should be stored away from heat sources and fires to prevent fires. In summary, the correct storage method is essential to guarantee the quality and prolong the service life of PPH pipes. During the storage process, the above points should be strictly adhered to ensure the safe, stable and efficient operation of the pipeline system.
