Problems solved by technology

[0002] At present, the use of PE steel wire composite pipes in domestic and foreign water supply and drainage and mining fields is more common. The electrofusion connection of low-pressure pipes is very common because of its joint stability, convenient construction and connection, and good corrosion resistance. In the field of pressure (1.6~5.0MPa), the electrofusion connection method cannot meet the use requirements
[0003] At present, for such medium and high pressure PE steel wire composite pipes at home and abroad, the pipe connection can only be connected by clamp buckle iron sheet combination or flange buckle iron sheet combination. Both of them cannot effectively avoid the damage of the outer layer PE and the composite layer caused by the crimping of the iron sheet, and the phenomenon of the steel wire of the composite layer passing through occurs from time to time; at the same time, the connection methods of the two do not meet the sanitary requirements of GBT 17219 and cannot be used in the field of water supply and drainage

Abstract

The invention relates to a processing method for quick-connecting joints of high-pressure flexible PE steel wire composite pipes, which comprises the following steps: a) the high-pressure flexible PE steel wire composite pipes are blown to the ends of the pipes through high-pressure nozzles; b) the third idler mechanism Consigned to the heating zone of the first pipe oven for heating; c), consigned by the second roller mechanism to the heating zone of the second pipe oven for heating; d), one end of the high-pressure flexible PE steel wire composite pipe is passed by the first roller The mechanism is consigned to the pier pressure area of ​​the pier pressure forming mold of the connecting head for pier pressure forming to form the pier edge. The invention also relates to a high-pressure flexible PE steel wire composite pipe quick-connect joint processing system. The invention has the following beneficial effects: the pipes with high-pressure flexible PE steel wire composite pipe quick-connect joints have excellent performances such as corrosion resistance, high pressure, and flexible quick-connection. Its joint strength is more than 2 times that of ordinary joints.
