Problems solved by technology

Furthermore, the PEX pipes are all produced with new materials, and there cannot be a single piece of recycled material, so the hygienic performance is more guaranteed. However, in the prior art, due to the connection and laying problems of the PEX pipe fittings, water leakage at the connection of the PEX pipe fittings, and aging phenomenon will also occur. , which will seriously affect the service life of PEX pipe fittings

Embodiment Construction

[0021] The following descriptions are only preferred embodiments embodying the principles of the present invention, and do not therefore limit the protection scope of the present invention

[0022] An embodiment of a connection and laying method that can prolong the service life of PEX pipe fittings of the present invention comprises the following steps: (1) placing the clamping ring on the PEX pipe fittings; (2) expanding one end of the PEX pipe fittings with a mouth expander (3) Insert another PEX pipe fitting from the flaring end of the PEX pipe fitting; (4) Clamp the clamping ring so that the two PEX pipe fittings fit together; (5) Lay the pipe through the wall time like figure 1 As shown, a perforation is first opened on the wall surface 5, and then the PEX pipe fitting 1 is placed in the perforation, and the copper ring 2 is fixed and clamped on the PEX pipe fitting section located in the perforation. Specifically in this embodiment, the PEX pipe fitting section Two cla...

Abstract

The invention discloses a connecting and laying method capable of prolonging the service life of a PEX pipe. The connecting and laying method capable of prolonging the service life of the PEX pipe comprises the steps that when a pipeline penetrating through a floor board is laid, a through hole is formed in the floor board firstly, the PEX pipe is placed in the through hole, a clamping copper ring is fixed to the section, located in the through hole, of the PEX pipe, the portion, penetrating out of the floor board, of the PEX pipe is sleeved with a galvanized metal sleeve, then fine sand concrete is poured in the through hole, and the clamping copper ring and the galvanized metal sleeve are poured in the through hole. By the adoption of the connecting and laying method capable of prolonging the service life of the PEX pipe, the service life of the PEX pipe can be effectively prolonged.

Description

Technical field: [0001] The invention relates to the technical field of PEX pipe fittings, in particular to a connection laying method that can prolong the service life of PEX pipe fittings. Background technique: [0002] At present, PEX pipes have been widely used in water supply systems in some developed countries. PEX pipe is made of high-density polyethylene with the best hygienic grade. After chemical cross-linking, the molecular structure is changed from linear arrangement to three-dimensional network structure, and thermoplastic plastic is changed to thermosetting plastic, thus greatly enhancing the performance of the pipe. The service temperature is -70℃~+110℃, the working pressure is 12.5 kg / CM2, the service life is more than 100 years at 50 ℃, and more than 50 years at 95 ℃, and its pressure life ratio is 10 times that of PP-R and other hot-melt pipes above. (The above data can be found in the Water Supply and Drainage Design Manual). Furthermore, the PEX pipes ...
