Abstract
The utility model discloses a plastic-lined steel composite pipe with an edge expanding flange. The plastic-lined steel composite pipe comprises a composite pipe body. A steel pipe edge expanding head is arranged at the opening of the composite pipe body. Plastic-lined coating layers are arranged on the internal sides of the steel pipe edge expanding head and the composite pipe body. A loose flange is arranged at a position close to a bayonet on the external side of the composite pipe. The plastic-lined steel composite pipe with the edge expanding flange has the advantages that the connection of different displacements between flange bolt holes and equipment flange bolt holes is avoided, the costs of a large quantity of lap joint flanges can be reduced, the production efficiency is high, the plastic-lined steel composite pipe is convenient to use and install, and the use, popularization and application values are great.
Description
Technical field
The utility model relates to a kind of steel lined plastic compound pipeline anticorrosion mechanism, is specifically related to a kind of steel lined plastic compound pipeline with expanding the limit flange.
Background technique
Steel lined plastic compound pipeline is mainly used to carry the gas-liquid medium that is corrosive, be applied to the industries such as chemical industry, metallurgy, sewage treatment, restriction, power generation, connection use between traditional multiple tube be that lap joint flange connects, therefore need to expend a large amount of flanges.
The model utility content
Goal of the invention: the utility model provides a kind of steel lined plastic compound pipeline with steel pipe expansion end that can reduce a large amount of lap joint flange link costs in order to solve the deficiencies in the prior art.
Technological scheme: in order to realize the foregoing invention purpose, the technical solution adopted in the utility model is: a kind of steel lined plastic compound pipeline that expands end with steel pipe, comprise the multiple tube body, the opening of described multiple tube body is provided with steel pipe and expands end, described steel pipe expands end and multiple tube body inboard and is equipped with lining and moulds coating, and the multiple tube outside is provided with loose hollow flange near opening.
Described multiple tube is steel pipe.
Beneficial effect: compared with prior art, the utility model adopts steel pipe to expand the limit, connect with loose hollow flange simultaneously, reduce a large amount of flange welding technique, owing to being loose hollow flange structure, avoided being connected of flange bolt hole and vessel flange bolt hole diverse location degree, can reduce a large amount of lap joint flange costs, and the utility model production effect is high, and is easy to install and use, and tool uses application value widely.
Description of drawings
Accompanying drawing 1 is the utility model structural representation,
Embodiment
The utility model is elaborated below in conjunction with accompanying drawing.
As shown in Figure 1, a kind of steel lined plastic compound pipeline with expanding the limit flange, comprise multiple tube body 1, the opening of multiple tube body is provided with steel pipe and expands end 2, steel pipe expands end 2 and multiple tube body inboard and is equipped with lining and moulds coating 3, the multiple tube outside is provided with loose hollow flange 4 near opening, and multiple tube is steel pipe.
first need to cut steel pipe blanking with a tree name duct length, and have and expand end cosine law amount, need when second expands the limit duct length location limit for length, and be set with two flanges, guarantee that this root pipeline reaches designing requirement, lower step operation is carried out exactly the inside lining and is moulded processing, the utility model adopts steel pipe to expand the limit, just play two lap joint flange effects with a slice flange, connect with loose hollow flange simultaneously, reduced a large amount of flange welding technique, owing to being loose hollow flange structure, avoided being connected of flange bolt hole and vessel flange bolt hole diverse location degree, can reduce a large amount of lap joint flange costs, and the utility model production effect is high, easy to install and use, tool uses application value widely.
