Multifunctional double-wall glass steel pipe and preparation method thereof

Abstract

The invention discloses a multifunctional double-wall glass steel pipe and a preparation method thereof. The double-wall pipe comprises an inner pipe, and an outer pipe arranged outside the inner pipein a sleeving mode; an insulation layer is arranged between the inner pipe and the outer pipe; a leakage channel is arranged between the insulation layer and the inner pipe in the length direction ofthe inner pipe; and the leakage channel communicates with the outer wall of the inner pipe. The preparation method comprises the following steps: the outer pipe is arranged outside the inner pipe inthe sleeving mode; a mold of the leakage channel is arranged between the inner pipe and the outer pipe; the mold is contacted with the outer wall of the inner pipe; blockage plates are fixedly arranged at the two ends of a pipe cavity between the inner pipe and the outer pipe, and are provided with injection holes and exhaust holes; foaming materials are injected from the injection holes; and themold is pulled out after foaming is finished. The double-wall pipe is simple in structure, easy to manufacture and low in cost, and integrates such multiple functions as the double-wall structure, theinsulation function, capability of detecting and alarming, capability of collecting leaked liquid and capability of positioning.

Description

technical field [0001] The invention relates to a pipeline and a preparation method thereof, in particular to a multifunctional double-wall glass fiber reinforced plastic pipeline for waste liquid produced during nuclear waste treatment and a preparation method thereof. Background technique [0002] During the treatment of nuclear waste, a large amount of highly radioactive waste liquid will be produced, which needs to be transported to a professional sewage treatment plant for special treatment over a long distance. At present, transmission pipelines sometimes need to be laid on the ground and work in a sub-zero environment, while traditional transmission pipelines are single-wall pipes, once leakage occurs, it will cause serious pollution to the environment. [0003] Therefore, there is an urgent need for a safe and reliable nuclear waste treatment waste liquid delivery pipeline that can be used in a low temperature environment. When the pipeline leaks, it can be quickly f...
