Description

Technical Field

[0001] The utility model relates to the technical field of PVC pipes, in particular to a novel PVC double-layer axial hollow wall pipe. Background Art

[0002] PVC pipe is the material used to make pipe fittings. PVC pipe is widely used, especially in municipal engineering construction, large factories, and urban construction. There are many different types of PVC pipe, each with its own usage environment. Different pipe fittings require different PVC pipes, and the quality of the PVC pipe directly determines the quality of the fittings. This type of PVC pipe is widely used in construction projects, power plants, and chemical plants. PVC, or polyvinyl chloride, is a polymer material obtained by the addition polymerization of vinyl chloride. It is the third most widely produced synthetic plastic polymer after polyethylene and polypropylene.

[0003] The development of the plastics industry has achieved remarkable results, especially in the fields of construction, packaging and agriculture. However, traditional PVC pipes have the problems of poor heat resistance and low compressive strength during use. In order to improve the thermal conductivity and compressive strength of PVC pipes. Therefore, a new type of PVC double-layer axial hollow wall pipe is needed. The existing new type of PVC double-layer axial hollow wall pipe will become brittle in cold weather and will break after being impacted. At the same time, it is easy to freeze and crack when there is water inside the PVC pipe. The existing new type of PVC double-layer axial hollow wall pipe mainly adopts solvent adhesive bonding when connecting. The PVC pipe cannot be rotated and adjusted after connection, and the bonding part does not have corresponding buffering performance, which easily causes the connection to crack and break when subjected to external force.
