Problems solved by technology
Especially in the construction process of buildings in saline-alkali environment, due to the presence of a large number of corrosive media in the saline-alkali environment, the service life of the building is the first. Damage occurs, shortening the service life of the pipe
There are various types of anti-corrosion rotomoulding pipes on the market, but their anti-corrosion effect is not good, and they do not have the function of shock absorption. The pipe body is easily deformed by external force, so it is not suitable for popularization.

Embodiment Construction
[0016] see Figure 1-Figure 3 As shown, the technical solution adopted in this specific embodiment is: a hot rotomolded pipe, which consists of a pipe body 1, a lining plastic 11, a shock-absorbing layer 12, a shock-absorbing cavity 121, a base pipe 13, a steel pipe 14, and an intermediate layer 141 , anticorrosion layer 15, insect repellant 151, protective layer 16, and flange 2. The inside of the pipe body 1 is lined with plastic 11, and the outside of the lined plastic 11 is equipped with a shock-absorbing layer 12. The inside of the shock-absorbing layer 12 forms a shock-absorbing cavity 121. The setting of the damping layer 12 and the damping cavity 121 improves the damping capacity of the pipeline body, so that the pipeline body has a damping function, and the pipeline body is not easily deformed by external force. A steel pipe 14 is arranged on the outside, and the steel pipe 14 is connected to the base pipe 13 through an intermediate layer 141. The outer surface of the...

The invention relates to a hot rotomolding pipe and a manufacturing method thereof, which relate to the technical field of pipes. A thermal rotomoulding pipeline, which includes a pipeline body, a plastic lining, a shock-absorbing layer, a shock-absorbing chamber, a base pipe, a steel pipe, an intermediate layer, an anti-corrosion layer, an insect-repelling agent, a protective layer, and a flange, and the inside of the pipeline body is provided with a plastic lining , a plastic-lined exterior is fixed with a shock-absorbing layer, and a shock-absorbing cavity is formed inside the shock-absorbing layer, and the outside of the shock-absorbing layer is fixedly connected to the base pipe. The protective layer is covered, and the pipe body port is welded to the flange. After adopting the above technical solution, the beneficial effects of the present invention are: its design is reasonable, it has strong corrosion resistance and shock absorption capacity, the pipeline body is not easily deformed due to external force, the service life has been strengthened, and it is suitable for popularization and use .
Description
technical field [0001] The invention relates to the technical field of pipes, in particular to a hot rotomolded pipe and a manufacturing method thereof. Background technique [0002] As a national infrastructure construction, the transportation pipeline is an important basic measure in the national economic construction, and anti-corrosion is an important measure in the transportation pipeline; the temperature, the concentration of the corrosive medium and the stress state will all affect the degree of pipeline corrosion. Especially in the construction process of buildings in saline-alkali environment, due to the presence of a large number of corrosive media in the saline-alkali environment, the service life of the building is the first. Damage occurs, shortening the service life of the pipe. There are various types of anti-corrosion rotomolded pipes on the market, but their anti-corrosion effect is not good, and they do not have the function of shock absorption. The pipe b...
