Steel wire mesh frame polyethylene composite tube external layer sizing sleeve

Abstract

The invention relates to a steel wire mesh frame polyethylene composite tube external layer sizing sleeve. The steel wire mesh frame polyethylene composite tube external layer sizing sleeve is arranged and connected between a steel wire mesh frame polyethylene composite tube extruder head and a vacuum cooling sizing box, and comprises a sizing sleeve water ring, a sizing sleeve inner core and a connecting flange, the sizing sleeve inner core is inlaid in the sizing sleeve water ring, the sizing sleeve water ring is provided with water inlets and a water outlet, the sizing sleeve water ring and the connecting flange form one body, steel frame polyethylene composite tube production line external layer vacuum sizing box is connected through the flange, and the sizing sleeve water ring penetrates deeply into the vacuum sizing box. The steel wire mesh frame polyethylene composite tube external layer sizing sleeve has the advantages of simple structure and installation convenience, and allows the outer wall of the tube to be flattened and smooth through friction of the outer wall of the tube and the inner wall of the sizing sleeve inner core when the tube passes by the sizing sleeve. The appearance of the steel wire mesh frame polyethylene composite tube of different specification models can be completely improved by replacing different specification models of the sizing sleeve.

Description

technical field [0001] The invention relates to a pipe forming equipment, in particular to a sizing sleeve for the outer layer of a polyethylene composite pipe with a steel mesh skeleton. Background technique [0002] Steel mesh skeleton polyethylene composite pipe is a new type of high-tech and environmentally friendly chemical pipe that has emerged in China in recent years. HDPE) is a new type of pipe that uses high-performance HDPE modified bonding resin to tightly connect the steel wire skeleton with the inner and outer layers of high-density polyethylene. Widely used in oil fields, urban water supply, power plants, chemical and petrochemical enterprises, water companies, municipal gas, metallurgical mines, seawater utilization pipelines and other fields. [0003] At present, the use of sizing sleeves in the plastic pipe industry is relatively common, but it is only used in PE and PVC pipes. The use of sizing sleeves in the production process of steel mesh skeleton poly...

Problems solved by technology

[0003] At present, the use of sizing sleeves in the plastic pipe industry is relatively common, but it is only used in PE and PVC pipes. In the production process of steel mesh skeleton polyethylene composite pipes The use of the sizing sleeve is currently only used for the sizing sleeve of the core tube. There is no domestic use of the sizing sleeve on the outer sizing. However, the outer sizing sleeve designed by us through independent research and development has been successfully tested in our company. The quality and appearance of the pipe produced after using the outer sizing sleeve surpasses similar products without the outer sizing sleeve
