Ultrahigh-molecular polyethylene pipe

Abstract

The invention discloses an ultrahigh-molecular polyethylene pipe. The ultrahigh-molecular polyethylene pipe comprises a pipe body, a left connecting flange, an upper pipe orifice, a pipe orifice connecting flange, a welding material port, a right connecting flange, an outer reinforcing layer, an ultrahigh-molecular polyethylene layer and an inner reinforcing layer; the pipe body is divided into three sections; the three sections of the pipe body are connected in sequence through the left connecting flange and the right connecting flange; the left connecting flange and the right connecting flange sleeve the pipe body; the upper pipe orifice is formed in middle of the left connecting flange and the right connecting flange; the pipe orifice connecting flange is arranged under the upper pipe orifice, and is connected with the welding material port; the outer reinforcing layer is arranged on the outer surface of the pipe body; and the ultrahigh-molecular polyethylene layer is arranged on the inner side of the outer reinforcing layer. Ultrahigh-molecular polyethylene is used as raw materials, and glass fibers are added in the inner reinforcing layer, so that the heat resistance and the strength of the pipe body can be improved, and mediums with higher temperature can be adapted to; and an inner lubricating agent is added in the ultrahigh-molecular polyethylene layer, so that the machining fluidity can be improved, the procedures are reduced, and the manpower is saved.

Description

Problems solved by technology

Ultra-high molecular weight polyethylene pipes were listed as the key promotion plan of national scientific and technological achievements by the Ministry of Science and Technology Guokejizi (2000) No. 056 document in 2001. They belong to new chemical materials and products. Excellent wear resistance, good low temperature impact resistance, self-lubrication, non-toxic, water resistance, chemical resistance, etc., but its heat resistance is poor, processing formability is poor, the outer surface hardness, rigidity and creep resistance are not as good as ordinary Engineering plastics often lead to the failure of ultra-high molecular polyethylene pipes. Therefore, it is necessary to further improve the structure of ultra-high molecular polyethylene pipes.
