Problems solved by technology

The disadvantages are that first, there is a certain deviation in the diameters of the metal pipe and the glass steel pipe. During the assembly process, it is difficult to assemble the outer glass steel pipe to a certain extent, and there are cracks. If there is a corrosive medium, the inner layer will be corroded and damaged; or If the size of the assembly is too large, there is a gap between the two materials, which cannot strengthen the effect; second, it is inconvenient to install because it belongs to two materials

Embodiment 1

[0035] Below in conjunction with accompanying drawing, the present invention will be further described:

[0036] Such as figure 1 , figure 2 As shown, a stainless steel strip composite pipe, the stainless steel strip composite pipe is composed of different glass fiber materials, and its composite pipe has a four-layer structure, from inside to outside: the first layer is stainless steel Wound inner cylinder 1, the second layer is the inner lining layer 2 wound with glass fiber surface mat, the third layer is the structure layer 3 wound with glass fiber yarn, glass fiber cloth and knitted mat, the fourth layer is the glass fiber surface mat The winding protective layer 4 is bonded by an adhesive between each layer.

[0037] The thickness of the inner cylinder 1 is 0.2mm-1mm, the thickness of the lining layer 2 is 1-2mm, the thickness of the structural layer 3 is wound according to different pressure levels, generally 6mm-20mm, and the thickness of the protective layer 4 is ...

Embodiment 2

[0039] Such as image 3 As shown, a stainless steel strip composite pipe, the stainless steel strip composite pipe is composed of different glass fiber materials, and its composite pipe has a four-layer structure, from inside to outside: the first layer is stainless steel Wound inner cylinder 1, the second layer is the inner lining layer 2 wound with glass fiber surface mat, the third layer is the structure layer 3 wound with glass fiber yarn, glass fiber cloth and knitted mat, the fourth layer is the glass fiber surface mat Wrapped protective layer4.

[0040] The preparation method of the above-mentioned stainless steel strip composite pipe comprises the following steps:

[0041] (1) A stainless steel strip is wound on the mandrel 5 to form the inner cylinder 1;

[0042] (2) Coating an adhesive on the surface of the wound inner cylinder 1;

[0043] (3) Wrap the glass fiber surface mat on the surface of the inner cylinder 1 coated with the adhesive to form the inner lining ...

Abstract

The invention discloses a stainless steel belt composite pipe and a manufacturing method thereof. The stainless steel belt composite material pipe is of a four-layer structure made of different glass fiber materials in a composite mode, namely a first layer, a second layer, a third layer and a fourth layer form inside to outside in sequence, the first layer is an inner cylinder wound by a stainless steel belt, the second layer is an inner lining layer formed by glass fiber surface felt in a winding mode, the third layer is a structure layer wound by glass fiber yarn, glass fiber cloth and glass fiber knitted felt, and the fourth layer is a protecting layer wound by glass fiber surface felt. The layers are bonded through adhesives. The stainless steel belt composite pipe has the advantages of being light in weight, high in structure intensity and good in safety and economy, and the anticorrosion capacity and the anti-oxidation capacity of the composite pipe are improved.

Description

technical field [0001] The invention relates to a stainless steel strip composite pipe and a preparation method thereof. Background technique [0002] Now all kinds of pipes are widely used in various fields of people's production and life. These pipes include metal pipes, such as steel pipes, cast iron pipes, copper pipes, etc., PVC pipes, such as water pipes, and composite pipes. Ferrous metal pipes have good structural strength, but are prone to corrosion, inconvenient construction, and high maintenance costs; non-ferrous metal pipes have good structural strength and corrosion resistance, but their cost is high and construction costs are high. PVC pipe is widely used because of its low cost and light weight, but its structural strength is poor, and its pipe diameter is relatively small due to the constraints of manufacturing equipment. [0003] Another Chinese patent No. CN200510027483.5 discloses a method for manufacturing a large-diameter wear-resistant and corrosion-r...
