Embodiment Construction

[0021] The technical solutions of the present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0022] FRP is the abbreviation of Fiber Reinforced polymer (fiber reinforced material).

[0023] Such as figure 1 with figure 2 As shown, the present invention provides a FRP bar composite stainless steel pipe, including a stainless steel pipe 20, an FRP bar 10 fastened on the outer surface of the stainless steel tube 20, and the FRP bar 10 includes a raised portion 11 and a threaded portion 12, The threaded portion 12 is continuously distributed on the FRP rib 10 . Under the condition of ensuring various performance indexes of the FRP-reinforced composite stainless steel pipe, the wall thickness of the stainless steel pipe 20 can be effectively reduced, material cost and material weight can be reduced; and the use of the FRP rebar 10 meets the development needs of a green and resource-saving society.

Abstract

The invention provides a fiber reinforced polymer (FRP) tendon and stainless steel tube composite and preparation technology thereof. The FRP tendon and stainless steel tube composite comprises a stainless steel tube and a FRP tendon fastened on the outer surface of the stainless steel tube, wherein the FRP tendon comprises bulge parts and screw thread shape parts, and the screw thread parts are continuously distributed on the FRP tendon. According to the FRP tendon and stainless steel tube composite and the preparation technology thereof, under the condition that all performance indices of the FRP tendon and stainless steel tube composite are guaranteed, the thickness of the wall of the stainless steel tube is effectively reduced, material cost and material weight are reduced, and the adoption of the FRP tendon meets requirements of environment protection and resource-conserving society development.

Description

technical field [0001] The invention relates to an FRP-reinforced composite stainless steel pipe which can be used in multiple fields such as medical equipment, domestic drinking water, and chemical drainage, and a preparation process thereof. Background technique [0002] Stainless steel pipes are safe, reliable, hygienic and environmentally friendly, and economical and applicable, making them irreplaceable by other pipes, and their application in engineering will become more and more popular. [0003] With the implementation of my country's reform and opening policy, the national economy has achieved rapid growth, and a large number of urban housing, public buildings and tourist facilities have been built, which puts forward new requirements for hot water supply and domestic water supply. Especially water problems, people more and more valued, pleas also driving forward. Galvanized steel pipe, a common pipe material, will gradually withdraw from the stage of history due t...
