PPH fittings and pipes should not be left exposed to direct sunlight for extended periods. To prevent bending during storage and transportation, they should be stacked flat with a maximum height of no more than 2 meters. When handling pipes and fittings, they should be handled with care to avoid oil stains and严禁剧烈撞击 or coming into contact with sharp objects. After the concealed pipes are covered and sealed, the location and direction of the concealed pipes should be clearly marked on a prominent wall. It is strictly prohibited to strike the pipes or nail metal pins and other sharp objects into them. Once installed, PPH pipes should not be used as ladders, hangers, or supports.
PPH fittings are β-modified from standard PP material, resulting in a uniform and fine Beta crystal structure. They offer excellent chemical resistance, wear resistance, insulation properties, high-temperature resistance, with operating temperatures up to 100°C, are non-toxic, and lightweight, making them easy to transport and install. This is an excellent product that is more heat-resistant, corrosion-resistant, and aging-resistant than standard PP pipes. PPH pipes are typically connected using hot melt welding machines, a method that is relatively common.法兰 connections are also used, but before doing so, the flange head must be thermally熔接 to the pipe or accessories. Additionally, due to the inclusion of flanges, the cost of the connection will also increase.
PPH pipes are typically connected using threaded joints, but this method is rarely used. It is usually employed when connecting PPH pipes to materials of the same type, as threaded joints have poor pressure-bearing capacity. They are generally suitable for small-diameter pipelines, usually below DN50. If installation of PPH pipes is required, it is crucial to find truly professional personnel to ensure the entire installation process is more secure. If the personnel chosen during installation are not sufficiently professional, it may lead to significant issues later on, which could ultimately have a greater negative impact on us.
