Plastic pipe with heat insulating and reinforcing functions

Abstract

The invention discloses a plastic pipe with heat insulating and reinforcing functions. The plastic pipe comprises a plastic base pipe body, wherein a reinforcing net cover is arranged in the pipe wall of the plastic base pipe body, the plastic base pipe body is sleeved with a heat insulating sleeve, and the heat insulating sleeve is sleeved with a reinforcing sleeve; a plurality of first reinforcing ribs are axially arranged on the outer wall of the plastic base pipe body, first grooves corresponding to the first reinforcing ribs are formed in the inner wall of the heat insulating sleeve, a plurality of second reinforcing ribs are axially arranged on the inner wall of the reinforcing sleeve, and second grooves corresponding to the second reinforcing ribs are formed in the outer wall of the heat insulating sleeve. In this way, overall structural strength can be improved through the first reinforcing ribs and the second reinforcing ribs; due to the fact that the heat insulating sleeve is located between the plastic base pipe body and the reinforcing sleeve, heat transfer is reduced, and the heat insulating and freezing prevention performance of the plastic base pipe body is improved; the deformation cracking resistance of the plastic base pipe body is improved through the reinforcing sleeve.

Description

Technical field [0001] The invention relates to the field of plastics, in particular to a plastic pipe with heat preservation enhancement. Background technique [0002] There are many types of plastic pipes, which can meet various needs and are widely used in daily life and production. [0003] Compared with steel pipes, plastic pipes will not rust, avoid rust wear or rust pollution to water, have good durability, and have a larger proportion in water pipes, but the low temperature resistance of plastic pipes is poor, mainly relying on the plastic material itself Low temperature resistance performance to ensure a certain low temperature resistance effect. In low temperature environments, the static water in the plastic water pipe is easy to freeze. Under the action of thermal expansion and contraction, the pressure distribution in the pipe is not uniform, and the pipe wall of the plastic water pipe increases sharply in local pressure. In this case, it is more likely to crack, and ...

Problems solved by technology

[0003] Compared with steel pipes, plastic pipes will not rust, avoid rust wear or rust to water pollution, and have good durability. They have a larger proportion in tap water pipes, but the low temperature resistance of plastic pipes is poor, mainly relying on the plastic material itself. Low temperature resistance is used to ensure a certain low temperature resistance effect. In a low temperature environment, the still water in the plastic water pipe is easy to freeze, and the pressure distribution in the pipe is not uniform under the action of thermal expansion and contraction. It is easier to crack under the environment, and the ability of heat preservation and compression resistance needs to be improved
