Internal curing forming mould for epoxy resin pipelines with large opening diameter and manufacture process thereof

Abstract

An internal curing forming mould for epoxy resin pipelines with large opening diameter and manufacture process thereof belongs to the technical field of production of epoxy resin pipelines. The mould is of a double-layer pipe structure, a temperature signal collector is arranged on the inner wall of a mould barrel body, an internal layer thermal insulation core pipe is arranged in the mould barrel body, a steam shower pipe is arranged between the internal layer thermal insulation core pipe and the mould barrel body, and the steam shower pipe is fixed on the internal layer thermal insulation core pipe through a steam shower pipe fixing frame. The internal layer thermal insulation core pipe is support by an internal layer thermal insulation core pipe support ring, a tail shaft is arranged at the rear end of the mould barrel body, a shaft head is positioned at the front end of the mould barrel body, and a shaft head connector is connected with a steam control device through a pipeline to automatically control steam flow. The manufacture process comprises the steps of processing and manufacturing the mould barrel body and a steel pipe of the internal layer thermal insulation core pipe, penetrating the internal layer thermal insulation core pipe into the processed mould to be fixed by a support frame, arranging the steam shower pipe and the temperature signal collector, welding two end sockets of the mould, leading a steam pipe and a data line of the temperature signal collector, connecting the steam controller, and forming a complete closed control system.

Description

technical field [0001] The invention belongs to the technical field of epoxy resin pipeline production. Background technique [0002] Large-diameter epoxy fiberglass pipe is a new type of non-metallic pipe that has only been popularized and applied in the domestic industry in the past two years. Especially in the field of offshore platforms and ships, domestic and foreign large-diameter epoxy pipes are produced using metal mandrels. After winding the resin and fiber on the mandrel, the mandrel and the external pipe are hung close to the curing furnace, and the external curing molding process is adopted. Because the external heating method is used in this molding process, the outer resin is first cured and the internal air bubbles in the pipe cannot be discharged, so the reduction It affects the compactness of the pipeline and affects the pressure resistance of the pipeline. At the same time, because the mold is continuously hoisted and transported from the main machine to t...

Problems solved by technology

[0003] The purpose of the present invention is to provide a large-diameter epoxy pipeline internal curing molding mold and manufacturing process to solve the problem that the current large-diameter epoxy pipeline can only be formed by external curing, and the outer layer of resin is first cured. The compactness affects the pressure resistance of the pipeline
