Patent DE-4023549-A1 (DE)
Inventor: SCHMIDT MANFRED
IPC: B29C63/00
Filed: 1990-07-25
Abstract: In the process proposed, a multi-layer hose comprising a fabric impregnated with a thermosetting resin is pulled into the pipe line, is sealed off at the ends and is inflated by introducing air. The thermosetting resin is then cured by passing warm air through the hose. The process is characterized in that the hose is initially inflated using unheated air, and heated air carrying steam is then passed through the hose, the temperature of the air introduced into the hose being raised initially to a value at which the thermosetting resin begins to soften, the temperature of the air subsequently being held constant and the pressure simultaneously increased until the increased internal pressure acting on the fabric causes the resin, which tends to drain down under the influence of gravity towards the bottom of the hose, to remain uniformly distributed over the hose cross-section, and the temperature is then raised further to a value above the curing temperature of the resin.
