Patent FR-2320816-A1 (FR)
Title: Thermoplastics tube socket formed by heating - with initially very hot progressively cooling fluid to reduce heating time
IPC: B29B13/02
Filed: 1976-08-06
Abstract: A method of heating or cooling the end zone of a thermoplastics tube to form an expanded socket consists of passing a heating or cooling fluid over the surface of the tube. During heating, the fluid temp. is high and is progressively reduced as the tube heats up. Conversely, during cooling the fluid temp. is initially very low and is progressively raised to the final temp. as the tube is cooled. Pref. the redn. and raised of temp. in the two processes is achieved by respectively adding a cooler fluid and adding a hotter fluid in the two cases. Pref. also a relatively high flow speed is used, a circumferential component being imparted to the fluid to produce a helical type flow. The fluid may be conducted simultaneously over the inner and outer faces in opposite axial directions. The use of an initially very high temp. for the heating fluid e.g. sufficiently hot to melt or even decompose the thermoplastics, ensures a high heat transfer coefft. at the boundary layer of a fluid adjacent to the tube surface. The fact that the tube itself is initially cool prevents it from becoming damaged by local surface heating since the boundary layer contains a steep temp. gradient. A considerable increases in heating up rate and redn. in heating time is attained, the same applies to the cooling stage, and a much reduced overall time for forming a socket is attained with relatively simple, mobile apparatus.
