Description

Technical Field

[0001] The utility model relates to the technical field of layer pipes, in particular to a continuous seamless replaceable elastic layer pipe. Background Art

[0002] Continuous seamless replaceable elastic layer pipe is an innovatively designed elastic layer pipe, which is usually used to transport various fluids, such as oil, natural gas, water, etc. It is used to transport raw materials, semi-finished products or finished products in various industrial production processes, such as chemical, pharmaceutical, food processing, etc. The elastic layer can prevent the inside of the pipe from corrosion or wear.

[0003] Traditional continuous seamless elastic layer pipes are not convenient for replacing the inner layer pipe and the elastic layer. When the inner layer pipe or the elastic layer is damaged or worn, the entire pipe needs to be replaced instead of just the damaged part. Since the entire pipe needs to be replaced, even if only a part of the inner layer pipe or the elastic layer is damaged, the entire pipe will be wasted, greatly increasing the cost of use.
