Carbon fiber reinforced plastic electric-smelting pipe fitting with strain self-monitoring function

Abstract

The invention relates to the field of thermoplastic plastic electric-smelting pipe fittings, and aims to provide a carbon fiber reinforced plastic electric-smelting pipe fitting with the strain self-monitoring function. The carbon fiber reinforced plastic electric-smelting pipe fitting comprises an electric-smelting pipe fitting body with a resistor wire buried, and two binding posts respectivelyconnected to the two ends of the resistor wire are arranged on the electric-smelting pipe fitting body. The carbon fiber reinforced plastic electric-smelting pipe fitting is characterized in that theelectric-smelting pipe fitting body is made of thermoplastic plastic filled with the carbon fiber, at least one set of paired electrodes is arranged on the surface of the electric-smelting pipe fitting body and used for monitoring the changes of the resistance values due to thermal temperature rising or internal pressure deformation in the suing process so as to achieve the strain monitoring of the electric-smelting pipe fitting. The carbon fiber reinforced plastic electric-smelting pipe fitting can improve the elastic modulus and yield strength of the material, has higher mechanical strength,higher blasting pressure, and can improve the operating pressure, the strain of the electric-smelting pipe fitting and the pressure inside the electric-smelting pipe fitting can be monitored, the additional equipment does not need, the intelligence and safety of the electric-smelting pipe fitting are improved, and the manufacturing process is simple, the stability is high, and the cost of the process is reduced.

Description

technical field [0001] The invention relates to the field of thermoplastic electric fusion pipe fittings, in particular to reinforced plastic electric fusion pipe fittings made of carbon fiber filled thermoplastics and the strain self-monitoring technology of the electric fusion pipe fittings. Background technique [0002] Compared with traditional metal pipes, plastics such as polyethylene and polypropylene and their composite material pipes have the advantages of high flexibility, good toughness, corrosion resistance, long service life, environmental protection and economy, and are recognized as "green" pipes. With the adjustment of my country's energy structure and the acceleration of urbanization, plastic and composite material pipes have been widely used in major national projects, such as high-pressure jumper pipes in tidal flats and shallow sea oil industries, and urban gas pipeline networks. Gas transmission pipes are used as cooling water circulation pipes in nuclear...
