Is steel belt reinforced bellows a plastic pipe? There are many people who would classify this pipe as a plastic pipe because it uses plastic polyethylene, is this statement correct?
First of all, this statement is incorrect, it does not belong to plastic pipes. So what kind of category does it belong to? This is from the perspective of its manufacturing and processing. Molding with steel strip and adhesive resin and polyethylene composite winding is simply a process in which polyethylene is heated and bonded together by applying adhesive resin to the steel strip, and then this composite steel strip is wound and molded by a wrapping machine. Seeing this, you should have some understanding, this kind of pipe does not belong to plastic pipes, nor does it belong to steel pipes, but belongs to steel-plastic composite pipes, the so-called composite is as mentioned above, composite steel belt and polyethylene two main materials.
As a kind of pipeline with good performance, it is mainly used in some areas where the ground is buried deep or the bearing pressure is large. For example, road traffic construction, due to the surface of the car more, often to the sewage pipe to cause greater pressure, this time it is more than the double-wall corrugated pipe advantages reflected, the bearing capacity can reach SN125 or more.
