Abstract

The invention relates to a hot-melting type static electricity conduction removal polymer oil conveying pipe union elbow and a preparing method thereof. The hot-melting type static electricity conduction removal polymer oil conveying pipe union elbow is characterized by comprising a static electricity conduction removal type polymer oil conveying inner tube elbow, a hot-melting type polymer outer layer sleeve and a filler; and the static electricity conduction removal type polymer oil conveying inner tube elbow and the hot-melting type polymer outer layer sleeve are in hot-melting connection through a hot-melting sealing assembly arranged on the hot-melting type polymer outer layer sleeve, and the filler is injected in from a filler injection opening formed in the hot-melting type polymer outer layer sleeve. The hot-melting type static electricity conduction removal polymer oil conveying pipe union elbow has the good static electricity conduction removal function, the problem that the difficulty is large when polymer oil conveying tubes are connected through the elbow or connected with a certain angle is solved, the structural design is reasonable, modularization machining can be achieved, and the very good project adaptability is achieved.

Description

technical field [0001] The invention belongs to the technical field of polymer oil pipeline connection, and relates to a pipe fitting joint for polymer oil pipeline connection, in particular to a hot-melt electrostatically conductive polymer oil pipeline elbow joint. technical background [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, when polymer oil pipelines are used to transport oil, static charges are easily generated on the inner wall of the oil pipe due to friction, impact, etc., which poses a safety hazard. The realization of static electricity removal has become the core key issue of polymer oil pipelines and their connecting fittings. [0003] In order to achieve static electricity removal, the polymer oil pipeline ha...
