A polymer oil pipeline joint that realizes static electricity removal by means of axial conduction of the pin on the end face of the spigot

Abstract

The invention discloses a polymer oil pipeline joint with static electricity guiding removal realized through conduction in the direction of the pins of a spigot end face. The polymer oil pipeline joint with static electricity guiding removal realized through conduction in the direction of the pins of a spigot end face comprises a polymer pipe (1), and is characterized in that an internally convex ring (2) is arranged inside the polymer pipe (1), a conducting ring (3) is bonded to the inner surface of the ring (2), a plurality of first pin holes (4) for inserting the pins (12) are formed in each of the end faces on the two sides of the conducting ring (3), and second pin holes (5) matched with the pins (12) in size are machined in the opposite positions of the end face of a polymer oil pipeline needing to be connected; and one end of each pin (12) made of the material same as the conducting ring (3) is inserted into the corresponding first pin hole (4), and the other end of each pin (12) is inserted into the corresponding second pin hole, so that it is realized that the conducting ring (3) and the conducting layer (6) of the polymer oil pipeline are electrically connected. The polymer oil pipeline joint with static electricity guiding removal realized through conduction in the direction of the pins of a spigot end face is simple in structure, and no oil conveying resistance or static electricity accumulation happens.

Description

technical field [0001] The invention belongs to the technical field of polymer oil pipeline connections, and relates to a polymer oil pipeline joint, in particular to a polymer oil pipeline joint that can realize static electricity conduction, in particular to a joint that achieves static electricity through axial conduction of pins on the end face of the stopper. Drained polymer fuel line fittings. Background technique [0002] Polymer oil pipeline has become the mainstream product in the oil pipeline market because of its light weight, corrosion resistance, small friction coefficient, convenient installation and maintenance, and easy leak detection, and the market prospect of this product is very broad. However, during the oil transportation process of the polymer oil pipeline, the inner wall of the polymer oil pipeline will generate electrostatic charges during the process of friction and impact. If the electric charge accumulates to a certain amount under the condition ...

AI Technical Summary

Problems solved by technology

However, this solution has the following deficiencies: First, although this solution achieves straight pipe connection and conduction, it increases the conductive sleeve, which will inevitably increase the cost

Second, compared with the smooth tube wall, the inner wall of the conductive sleeve and the joint form resistance to oil delivery, and impurities will also be deposited here. Long-term use will cause problems such as a decrease in the reliability of electrostatic connection

Third, this solution is not suitable for connection at a certain angle, or even if it can be used for corner joints through the deformation of the intermediate sleeve, there will be problems in its formability, engineering site adaptability and conduction reliability to varying degrees

[0004] It can be seen that there is currently no polymer oil pipeline joint, especially an elbow joint, that can realize static electricity removal, which limits the wide application of polymer oil pipelines in the field of petroleum transportation to a certain extent.
