Technical Field
[0001] The utility model relates to the field of winding wall pipe devices, in particular to a high molecular weight polyethylene hollow plastic steel winding structure wall pipe. Background Art
[0002] Hollow wall plastic-steel spiral pipe is usually used for municipal drainage. Its inner wall is smooth and flat, and it has the advantages of corrosion resistance, light weight, easy installation, large flow rate and long service life.
[0003] The existing hollow plastic-steel winding structure wall tube is produced by first producing a hollow plate strip and then adding a prefabricated steel strip, and then winding it with glue on both sides. This kind of tube has a high scrap rate in the early stage of plate strip production and is difficult to form. The preformed steel strip is difficult to adjust and has a lot of scrap. During winding, the pitch is limited by the steel strip and is difficult to operate and is easily stretched by the steel strip. Since the steel strip is not fixed in the tube, the tube shrinks greatly and is easy to deform. The steel strip is wavy, which is limited by the shape and requires a large amount of steel, which increases the production cost. Utility Model Content

The inner tube is simple to manufacture and has a low manufacturing cost. It is produced online synchronously with the winding molding, which reduces the storage space of the inner tube and saves storage costs. The inner tube winding tube making process is simplified, easy to control, and has a high yield rate. Finally, the steel belt is distributed vertically to the inner tube, which greatly improves the ring stiffness and evenly distributes the force, so that the product has a strong bearing capacity and is stable and durable.
