Ultra-high molecular polyethylene pipe

Abstract

The invention discloses an ultra-high molecular polyethylene pipe which comprises a steel pipe and an ultra-high molecular pipe. The ultra-high molecular pipe comprises a first high molecular layer, ametal net layer, a bonding layer, a second high molecular layer and an antistatic coating. A through hole is formed in the ultra-high molecular pipe in the radial direction. A metal column is fixedlyconnected into the through hole. The metal column makes contact with the metal net layer. The metal column is grounded. The antistatic design of the ultra-high molecular polyethylene pipe is adopted,by arranging the metal net layer, on one hand, the impact resistant performance and the deformation resistant performance of the pipeline can be improved, and on the other hand, the antistatic performance of the pipeline can be improved; due to the fact the motion speed of charges is approximate to the light speed, the positive and negative charges can be neutralized instantly when making contactwith the metal net layer; by means of cooperation of the antistatic coating with the electronic gaining and losing ability similar to a conveying medium, the defects that in the traditional technology, due to the insulation characteristic of a high molecular material at one end of a polyethylene pipe, the pipe wall and the medium rubs, and static electricity is generated easily can be effectivelyovercome.

Description

technical field [0001] The invention relates to the technical field of ultrahigh molecular pipes, in particular to an ultrahigh molecular polyethylene pipe. Background technique [0002] Polyethylene pipes are used in a wide range of fields. Among them, water supply pipes and gas pipes are the two largest application markets. Polyethylene resin is polymerized from monomer ethylene. Due to different polymerization conditions such as pressure and temperature during polymerization, resins with different densities can be obtained. Among them, ultra-high molecular weight polyethylene is composed of ethylene and butadiene monomers. Under the action of the catalyst, the thermoplastic engineering plastic with an average molecular weight of more than 2 million is polymerized, which has high wear resistance, improves the service life of the pipeline, and improves the transmission efficiency by about 20% compared with the steel pipe. [0003] Static electricity is caused by the conta...
