Abstract

The invention discloses a glass steel tube produced in a continuous winding process. The glass steel tube comprises an inner liner layer, a structural layer and an outer protection layer. The structural layer is formed by multiple long fiber layers and multiple short fiber layers at intervals in the vertical direction in a staggered and combined mode. Each long fiber layer comprises long cut glass fibers and resin, and each short fiber layer comprises short cut glass fibers, quartz sand and resin. The glass steel tube is manufactured in the continuous winding process with the resin serving as a substrate, the glass fibers as reinforced materials and the quartz sand as stuffing. Meanwhile, due to the facts that the structural layer is formed by the multiple long fiber layers and short fiber layers in a staggered mode and combination strength between the layers is high, the overall strength and rigidity of the glass steel tube are strong. Meanwhile, the glass steel tube has strong corrosion resistance and flexibility, stretching strength is much more excellent than that of an existing product, and service life of the glass steel tube can be more than 50 years.

Description

technical field [0001] The invention belongs to the technical field of glass steel pipes, and in particular relates to a continuous winding glass steel pipe. Background technique [0002] At present, there are three processes for the production of FRP pipes in my country, namely, continuous winding process, fixed-length winding process and centrifugal casting process. Among them, the production line of fixed-length winding pipe is a semi-automatic production equipment, the stability of product quality mainly depends on the proficiency of the operator, the production efficiency is low, and the sanding of fixed-length winding pipe adopts the sand wrapping process, that is, glass fiber The cloth wraps the quartz sand inside. Because the sand layer is isolated and helpless, the source of the resin used to infiltrate the quartz sand is the glass fiber cloth. When the fiberglass cloth is wound, the extrusion itself impregnates the resin and transfers to the quartz sand. It can be ...
