玻璃纤维缠绕成型弯管和等径三通,生产周期短、费用低。玻璃纤维可以缠绕PVC(聚氯乙烯)管件、玻璃管件、陶瓷管件和富树脂层内衬管件,由于纤维是连续缠绕的,因而力学性能好,能承受高压负荷。纤维缠绕成型的弯管、三通的连接形式,同金属管件一样可选用法兰、承插、螺纹和胶合等形式,其多数采用法兰连接。管件的种类规格较多,如弯管(90°正弯和Y型弯)、三通(等径和变径)、四通(等径和变径)、法兰、管箍、阀件等。这里仅介绍缠绕90°弯管和等径三通的工艺。
Glass fiber winding pipe bending and equal tee, short production cycle, low cost. Glass fiber can be wrapped around PVC (polyvinyl chloride) pipe fittings, glass pipe fittings, ceramic pipe fittings and resin-rich lining pipe fittings, because the fiber is continuous winding, so good mechanical properties, can withstand high pressure load. Filament winding wound pipe, tee connection form, with the same choice of metal pipe flange, socket, thread and glue and other forms, the majority of the flange connection. Pipe fittings of more types and specifications, such as the elbow (90 ° positive and Y-bend), three links (equal and adjustable), Stone (equal and adjustable), flanges, pipe clamps, valves, etc. . Here only describes the process of winding 90 ° elbow and tee.
