HDPE/PVC plum blossom pipe/grille pipe

　　Product Description
　　HDPE/PVC plum blossom tube/grid tube is produced by one-time extrusion molding of an extruder, and the walls of each single hole intersect and are tightly welded as a cable sheath pipe.
　　Performance characteristics
　　1. The plum blossom tube adopts a porous integrated structure, which has good rigidity and uniform force.
　　2. The pipe is smooth and flat, the color is uniform, the friction coefficient of the inner wall is small, the cable is threaded lightly, and the construction is simple and easy.
　　3. With multiple holes, pipe holes can be reserved to improve the utilization rate of communication holes.
　　4. Wide range of applicability (+80/40), can be used in tropical and cold regions. The joint adopts socket structure.
　　5. Any tool is needed to complete the connection between the pipes, which is convenient for construction and maintenance.
　　6. The service life of the plum blossom pipe is more than 30 years under the condition of buried depth.

　　7. Road engineering, used for underground threading of railways and expressways.
　　8. Mine. It can be used as mine ventilation, water delivery and drainage pipes.
　　9. The perforated double-wall corrugated pipe can be used as the seepage drainage pipe of the saline-alkali expressway.
　　10. Golf course and football field engineering, used for seepage and drainage pipes of golf courses and football fields.
　　11. Drainage and sewage pipes used in various industries. Such as large docks, port projects, large airport projects and so on.
　　Product Description
　　The specifications of the nine-hole grid pipe are BF9-33 and BF9-28. Using polyvinyl chloride as the main raw material, together with toughening agent, anti-aging agent and other auxiliary additives, etc., it integrates the sheath and the sub-tube, and is extruded at one time, with a beautiful appearance. The nine-hole grille tube is made of polyvinyl chloride as the main raw material, together with toughening agent, anti-aging agent and other auxiliary additives. It is a kind of perforated grid tube. In the process of producing nine-hole grid pipe, Yage requires quality clearance, and is equipped with professional raw material inspectors, supervisors in the production process, physical testers, chemical testers, workshop finished product inspectors, factory product inspectors, etc. Product inspection is strictly carried out in accordance with the procedures of material inspection, team self-inspection, full-time inspection, and factory inspection to ensure that product quality meets national industry standards.
　　Performance characteristics
　　Nine-hole grille pipe should pay attention to the depth (pipe top to road surface) during construction and design. It should not be less than 0.5M under the sidewalk, and should not be less than 0.7M under the roadway. It should cross the tram track (pipe top) to the bottom of the track) should not be less than 1.00M, and the intersection with the railway (pipe top to the bottom of the track) should not be less than 1.5M. When laying nine-hole grid plastic pipes in multiple layers, it should be filled in layers, and the buried deep. If these requirements cannot be met, protective measures such as concrete encapsulation or steel pipes shall be adopted.
　　The color of the pipe should be uniform, usually white or gray, and it can also be agreed upon by both the supplier and the buyer. The appearance of the pipe is not allowed to be deformed, twisted, and the pipe wall is not allowed to have bubbles, cracks, decomposition and discoloration lines and obvious impurities. The inner and outer walls should be smooth and flat . The section of the pipe should be cut flat and perpendicular to the pipe axis.
　　Product Application
　　The grid tube is suitable for telecommunications, cable television and other optical cables, and underground communication pipelines for cables. Introduction to the basic requirements of the grille pipe during construction and connection:
　　The shape of the inner wall of the pipe joint should be exactly the same as that of the outer wall of the porous pipe. After socketing, the gap between the inner wall of the pipe joint and the outer wall of the porous pipe should not exceed 0.5mm. The length of the pipe
　　joint It should not be less than 200mm.
　　·The inner wall of the inner cross-section at the longitudinal center of the pipe joint should have an annular rib. After the porous pipe is inserted into the joint, the rib is in contact with the outer wall of the end face of the porous pipe, and the contact width should not be less than 1.6mm
　　·The wall thickness of the pipe joint should not be less than the minimum wall thickness of the corresponding plastic pipe.
　　Vicat softening temperature ≥ 74°C (test method according to GB/T8802-2001)
　　Drop test (0°C, 30min 1.0m drop, no damage or cracks)
　　After hot oven test, it should meet the requirements (test method according to GB/T8802-2001) T8803-2001)
