Embodiment Construction

[0025] The technical solutions of the present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0026] FRP is the abbreviation of Fiber Reinforced polymer (fiber reinforced material).

[0027] like Figure 2 to Figure 3 As shown, the present invention provides a pipe joint, which includes a sleeve 5 and an FRP material 6 fastened on the outer surface of the sleeve 5 . Under the condition of ensuring various performance indexes of the pipe joint, the wall thickness of the casing 5 is effectively reduced, material cost and material weight are reduced; and the use of the FRP material 6 meets the development needs of a green, environment-friendly and resource-saving society. In the pipe joint produced by the present invention, the FRP material 6 is smooth so that the pipes can be connected through the insertion method, which well solves the limitation of the application of the pipes.

[0028] The FRP material 6 includes ...

Abstract

The invention provides a pipe connector and a manufacture method thereof. The pipe connector comprises a casing pipe and fiber reinforce plastic (FRP) materials, wherein the FRP materials are fastened on the outer surface of the casing pipe. The manufacture method of the pipe connector comprises a first step of placing and positioning the casing pipe in a die, a second step of placing the FRP materials into the die, a third step of extrusion forming, a fourth step of releasing the die and taking out the pipe connector, and a fifth step of trimming rough selvedges to form a pipe connector end product. Under a situation that all performance indexes of the pipe connector are guaranteed, the wall thickness of the casing pipe is effectively reduced, and material cost and weight are reduced. The FRP materials are adopted to conform to the developing demands of environmental protection and a resource-conserving society.

Description

technical field [0001] The invention relates to a pipe joint that can be used in multiple fields such as medical equipment, domestic drinking water, and chemical drainage, and a preparation method thereof. Background technique [0002] In the water supply system, stainless steel pipes, plastic pipes, composite pipes and copper pipes have become common pipe materials for piping systems. In the prior art, the wall thickness of various pipes is relatively large, resulting in high cost and heavy weight. Now relevant parties are researching safe, reliable, hygienic, environmentally friendly, economical and applicable pipes, especially in the case of ensuring various performance indicators of the pipes Under this condition, the pipe can reduce the wall thickness and reduce the price, which is conducive to further promotion. [0003] The pipe joints in the prior art also have the problems of large thickness, heavy weight and high cost. Contents of the invention [0004] The pur...
