Title:
HEAT-RESISTANT FLEXIBLE CONTINUOUS COMPOSITE LINING TUBE AND METHOD FOR MANUFACTURING SAME
Document Type and Number:
WIPO Patent Application WO/2017/096580
Kind Code:
A1
Abstract:
A method for manufacturing a heat-resistant flexible continuous composite lining tube comprises the following steps: weaving a reinforcement layer; using a drawing mechanism to draw the woven layer; extruding, by an inner layer extruder and a mold, an inner layer out of an opening on a top of the woven layer; applying a drawing force to cause the woven layer to pass through a heater; and during a process of plasticizing the inner layer, extruding an outer layer by an outer coating extruder and a mold. The method integrally forms a flexible tube by adhering rubber to the reinforcement layer via heating. The flexible tube of the invention can be installed conveniently, and has a high pressure-bearing capacity. After being installed, the flexible tube does not burst even if a fluid penetrates to the reinforcement layer. The flexible tube can be used at a temperature up to 150ºC .
