What are the advantages of HDPE winding structure wall B pipe in PE pipe?
Different pipes have different application fields, and there are countless products of different specifications for PE pipes. Do you know the characteristics of different PE pipes? HDPE 缠绕结构壁 B 型管 它有什么 优点 呢？ For example, what are the advantages of HDPE winding structure wall B -tube ? Do you understand Therefore, learning is endless. If you are not clear, this article can take you to the most comprehensive understanding of its advantages. After understanding it, it will be a good help for you in the future construction process.
① The HDPE winding structure wall B -type pipe has a large specific surface area, which enlarges the contact surface with the soil. The surface of the pipe is evenly subjected to external forces. The backfill soil filled in the trough of the pipeline and the pipeline itself bear the pressure of the surrounding soil to form pipe soil Together, they can quickly and completely decompose and transfer external loads into the entire pipeline, minimizing the impact of external loads on the pipeline itself;
② Resistance to toughness damage: HDPE winding structure wall B -shaped pipe with PP in the middle of the round reinforced corrugated pipe is the skeleton pipe, and is continuous winding the entire pipeline, which can greatly improve the structural stability of the wave crest and the stability of the ring stiffness Properties and pipe creep resistance, toughness has been greatly improved, has excellent resistance to toughness damage, and slow crack growth resistance is significantly improved;
③Tensile strength : The outer wall structure of HDPE winding structure wall B -type pipe is 30% -40% higher than that of hollow wall pipe . Therefore , the bonding surface of round reinforced corrugated pipe of HDPE winding structure wall B -type pipe is wider Greatly increase the tensile strength of the seam, so that the pipe has more excellent resistance to lateral tension;
④Anti-leakage ability: HDPE winding structure wall B -type pipe adopts socket-type electric heating fusion connection, and the socket and socket are made of solid-wall steel-plastic pipe, which has high precision, and the electric fuse is embedded in the socket. After the socket is inserted into the socket, the socket and the surface of the socket are melted together to achieve a sealing effect through current . The entire welding process is reliably achieved by temperature and time control using special equipment. This connection method will not only leak the The possibility is reduced in essence, while ensuring the strength of the interface and increasing the transverse tensile strength.
