Description

A fiberglass pipe

technical field

The utility model belongs to the field of pipelines, in particular to a glass fiber reinforced plastic pipeline.

Background technique

Currently on the market, metal pipes or non-metal composite pipes are mostly used for liquid transportation in oil fields, mines, and drainage industries. When metal pipes transport liquids, the pipes are severely corroded and scaled, and their service life is short. FRP pipes and FRP composite pipes, etc. Among them, FRP pipes have attracted widespread attention due to their light weight, high strength, and corrosion resistance. Scale, corrosion and other problems, and then cause the friction resistance of liquid flow in the glass pipe to increase or liquid leakage and other phenomena.

Contents of the invention

The purpose of the utility model is to provide a glass fiber reinforced plastic pipeline, which can transport liquids in different environments; has high reliability of anti-seepage, high transport efficiency and long service life.

The technical scheme adopted by the utility model to solve the technical problem is: a glass fiber reinforced plastic pipe, which is respectively an inner lining layer, an anti-seepage layer, an outer protective layer and an anti-skid layer from the inside to the outside, and is bonded together by resin curing. The inner lining layer is made of reinforced resin, the anti-seepage layer is made of gel coat layer, surface felt, knitted felt and grid cloth after lamination, and the outer protective layer is a composite structure made of fiberglass fiber and unsaturated polyester. layer, an inner protective film is arranged on the inner surface of the inner lining layer, and an anti-slip layer is arranged on the outer surface of the outer protective layer.

Preferably, the inner protective film is a polyester film; the thickness of the anti-seepage layer is 10-20mm.

The beneficial effects of the utility model are: a glass fiber reinforced plastic pipe of the utility model is bonded with a multi-layer structure, which is light in weight, high in strength, and has a long service life; Corrosion; there is a layer of inner protective film on the inner surface of the inner liner, which makes the inner surface of the glass steel pipe smoother and less prone to scaling, which can significantly reduce the loss of frictional resistance along the flow of liquid, and the transmission efficiency is high; the anti-seepage The layer is made of four layers of different materials after lamination, with strong anti-seepage ability, forming four protective walls, which can transport liquids with different pH and different environments; it has high anti-seepage reliability.

Detailed ways

The technical scheme of the utility model is further illustrated below through specific examples.

As shown in Figure 1: a glass fiber reinforced plastic pipe, from the inside to the outside is respectively an inner lining layer 1, an anti-seepage layer 2, an outer protective layer 3 and an anti-skid layer 4, and is bonded together by resin curing. The inner lining layer 1 Made of reinforced resin, the anti-seepage layer 2 is made of gel coat layer 21, surface felt 23, knitted felt 22 and mesh cloth 24 through lamination, the gel coat layer 21 can be pure resin, the gel coat layer 21 The thickness is 0.5mm.

The outer protective layer 5 is a composite structural layer made of fiberglass fiber and unsaturated polyester, which has high strength and long service life; The outer surface of the protective layer 3 is provided with an anti-skid layer 4 .

Preferably, the inner protective film 5 is a polyester film; the thickness of the anti-seepage layer is 10mm.

A glass fiber reinforced plastic pipe of the utility model is bonded with a multi-layer structure, which is lightweight, high-strength, and has a long service life; the inner lining layer 1 is made of reinforced resin and has high strength and corrosion resistance; the inner lining layer The inner surface of 1 is provided with a layer of inner protective film 5, so that the inner surface of the glass steel pipe is smoother, less prone to fouling, and can significantly reduce the loss of frictional resistance along the flow of liquid; the anti-seepage layer 2 is composed of four layers of different materials through layers Pressed, strong anti-seepage ability, forming four protective walls, can transport liquids with different pH and different environments; it has high anti-seepage reliability.

Except for the technical features described in the description, all are technologies known to those skilled in the art.
