Description

Technical Field

[0001] The utility model relates to the technical field of PPR thermal insulation pipe fittings, in particular to an anti-corrosion PPR thermal insulation pipe fitting. Background Art

[0002] PPR pipe is also called type III polypropylene pipe and also called random copolymer polypropylene pipe or PPR pipe. As a new type of water pipe material, PPR insulation pipe has unique advantages and can be used as both cold water pipe and hot water pipe. PPR insulation pipe is gradually becoming a popular insulation material due to its non-toxicity and light weight.

[0003] When using PPR pipes, for the sake of aesthetics, they need to be hidden in the wall or underground during installation. Therefore, they are easily squeezed during use. During long-term use or after being squeezed, the PPR pipes are easily deformed, which reduces the service life of the PPR pipes. Therefore, we propose an anti-corrosion PPR insulation pipe fitting.

Therefore, when the pipe fitting body is in use, the pipe fitting body is prevented from being squeezed and deformed, thereby causing damage to the pipe fitting body. At the same time, a second reinforcement layer is set in the pipe fitting body to prevent the pipe fitting body from being deformed, thereby increasing the supporting strength for the pipe fitting body and thus avoiding damage to the pipe fitting body.
