Large-diameter pp pipe is an important pipeline for sewage and an important part of urban water supply, so it has higher requirements for drainage pipes. The large-diameter pp pipe can meet the requirements of pipeline layout and drainage, and has outstanding performance. The advantages of large-diameter pp pipe water supply pipes are introduced below.
- The large-diameter pp pipe has good physical properties. The rigidity, strength, flexibility and creep resistance of the pipe are all based on medium density polyethylene, which is helpful for the construction of pipeline equipment on the hot melt connection.
- Large diameter pp pipe has good corrosion and long service life. The offshore water level is high, the soil humidity is high, and smooth steel pipes are used, which are easy to rust and have a short service life. long.
- The large-diameter pp pipe has good durability and good flexibility. The large-diameter pp pipe has a large elongation at break, has strong prominent uneven settlement and dislocation habits, and has strong impact resistance. This kind of pipeline system is stable and firm, and during construction, it can bypass the bending radius of the pipeline and reduce the difficulty of construction.
- Large diameter pp pipe has strong vitality. Due to the characteristics of pipe wall lubrication, auxiliary structure, small resistance, fast water flow speed and large flow rate, compared with other pipes, the flow capacity is strong, which can save costs.
- The construction is convenient, the pipeline is light in weight, convenient for movement and equipment, and is connected by hot-melt connection, which is well sealed and firm. In addition, the immersed pipe method can also be selected to lay pipes at the bottom of the water to reduce construction difficulty and engineering costs.
- The sealing performance is good, the selection of welding method can ensure the interface quality, end the combination of the joint and the pipeline, and the interface strength is also higher than the tubular object itself, which is safe and reliable.
