PP-R pipe

Abstract

The invention belongs to the technical field of plastic pipes, and particularly relates to a PP-R pipe which comprises a pipe body. Ribs are arranged on the pipe body, a plurality of microelectronic devices used for monitoring the application condition of the pipe are arranged in the ribs, and the ribs are evenly distributed on the pipe body at intervals. The strength and weather resistance of the pipe are effectively improved, creep deformation of the pipe is reduced, meanwhile, the use condition of the pipe can be monitored, and pipe maintenance is facilitated.

Problems solved by technology

[0002] The single-layer solid-wall PP-R water supply pipes currently produced have the advantages of light weight, high cost performance, safety and hygiene, and convenient transportation and installation. However, the products also have high cost, high brittleness in cold temperatures, and thermal deformation in hot temperatures. The creep is large, and there is no monitoring function in the later stage of actual application, etc.

The current solid-wall pipe products are in the form of colored lines. The material of the color line is a mixture of PP-R raw materials and color masterbatches. The color line is only used to distinguish the application types of pipes. The cost, performance and creep are almost the same as those of full-wall pipes. The products of PP-R materials are consistent, that is, high cost, high price, unstable performance, large creep and no monitoring function in the later stage of actual application, etc. If we want to increase product functions and broaden the scope of product application, the above defects need to be resolved urgently

[0003] According to the status quo of the industry, some pipes are provided with ribs. For example, the patent with the application number 2019213828691 published on June 19, 2020 is called a pressure-resistant PPR pipe. Insulation material is added in the groove. Although this patent improves the compressive performance of some PPR pipes, the instability of the insulation material still cannot solve the problem of large creep of PPR pipes.

Another example is the patent application number 201922166515X published on July 17, 2020, which is called a plastic tube with a detection chip. The patent has a cavity inside the tube, and multiple probes are installed on the inner wall of the detection cavity. A casing is installed on the outer wall of the pipe, and a signal transmitting antenna is arranged around the casing; although this patent can detect the use of the pipe, the internal structure is complicated, which is not conducive to popularization and use
