Features, applications of internal rib winding tube equipment and its products

Thread Content

The internal rib winding tube equipment, also known as structural wall tube equipment, produces internally ribbed reinforced polyethylene spiral corrugated tubes, which represent the latest type of fully plastic internally ribbed reinforced winding corrugated tubes developed in the current market. The pipes are made from high-density polyethylene (HDPE); they have a large surface area, which enables joint compression resistance between the pipe and the soil. It provides good welding quality and enhances the tensile strength of the seam. The internal rib structure helps to improve the stability of ring stiffness. The spiral corrugated structure of the polyethylene spiral corrugated pipe reinforced with internal ribs is well-designed; it helps to increase the contact area with the soil. The backfill material filled in the troughs of the pipe, together with the pipe itself, can share the pressure from the surrounding soil. This allows for a combined action between the pipe and the soil, enabling external loads to be dispersed and transmitted throughout the entire pipeline quickly and effectively, thereby minimizing the impact of those external loads on the pipeline itself ； The ability to resist toughening failure. The vertical internal ribs located in the middle of the corrugations of the inner ribbed pipe enhance the stability of the wave peaks, which contributes to better resistance to compression and impact. The large width and excellent quality of the weld seam on plastic strips result in a high tensile strength of the pipe seams. The connections of the polyethylene spiral corrugated pipes reinforced with internal ribs, produced by internal rib winding equipment, are secured through socket-electrofusion to ensure zero leakage, while stainless steel clamp connections offer convenience and reliability. The socket and spigot are made from solid-wall PE pipes, offering high precision. An electric heating network is arranged within the spigot; when the spigot is inserted into the socket, an electric current is used to melt the PE material on the surfaces of both the spigot and the socket, thereby achieving a sealed connection. The entire welding process is carried out using specialized equipment, with temperature and time controlled to ensure reliability. This type of connection not only reduces the likelihood of leaks to a minimum but also enhances the strength of the joint as well as its resistance to lateral forces. The pipes produced by internal rib-wound tube equipment have a large specific surface area, which increases the contact area with the soil. The pipe surface is subjected to uniform external forces; the backfill material filled in the troughs of the pipe, together with the pipe itself, bear the pressure from the surrounding soil, thereby creating a combined action between the pipe and the soil. The internal ribs in these polyethylene spiral corrugated pipes are vertical, and they are continuously wound around the entire length of the pipe, which greatly enhances the structural stability of the wave peaks, the stiffness of the pipe, and its resistance to creep. The toughness of these pipes is significantly improved, giving them excellent resistance to brittle failure, as well as enhanced resistance to slow crack growth ； Tensile strength: The outer wall structure of the polyethylene spiral corrugated tube reinforced with internal ribs is 40% thicker than that of the hollow-walled tube; as a result, the bonding surface of the internal rib hollow strips in this type of tube is wider and thicker, **which increases the tensile strength of the seams and thus gives the tube superior resistance to lateral pulling forces ； Current internal rib winding tube manufacturing equipment available on the market is capable of producing internal rib reinforced polyethylene spiral corrugated tubes in various sizes ranging from DN200 to 3000 mm. The length of these tubes is usually 6 meters or 9 meters, with ring stiffness levels of SN6.3, SN8, SN10, and SN12.5. The inner-ribbed pipes produced by inner-rib winding pipe equipment have advantages such as light weight, high pressure resistance, and excellent joint quality; they are used in pipelines for discharging corrosive wastewater in industries such as seawater treatment, manufacturing, chemical plants, and pharmaceutical factories ； Old city renovation, separate systems for rainwater and sewage, sewage treatment plants, wastewater from waste disposal facilities ； Municipal projects, buried drainage systems in construction projects, power plants, and other large-scale engineering projects ； Irrigation and drainage in agricultural fields ；
