Description

A kind of sun protection reinforced PE pipe

technical field

The utility model relates to a sun-proof reinforced PE pipe.

Background technique

In the production of fine chemicals, pipeline transportation of liquid materials is one of the most common chemical unit operations. It is a process in which the fluidity of the liquid substance is used to pressurize one side of the pipeline with pumps and other equipment, and the liquid flows from the high-pressure side to the low-pressure side. At present, there are many kinds of pipelines that can transport liquids, but most of the same pipelines have a small scope of application when transporting different liquid materials. Enamel or glass pipelines with a wide application range are expensive to manufacture and complicated to install and maintain.

In the transportation of low-metal liquid materials, enamel or glass pipelines are generally used. The enamel sometimes falls off during use, and because it is wrapped in carbon steel outside, it is difficult to find, resulting in unqualified materials; glass pipeline joints are easy to leak, easy to Broken, high cost.

When PE is used as a pipe, it cannot be used outdoors for a long time because it is not resistant to sunlight, and because the pipeline is soft, it cannot be erected at high altitude like other pipelines. Thus affecting its scope of use.

During the use of the metal-plastic composite pipe, due to the environment and improper use, the plastic layer and the metal layer are easily peeled off, or the pipe is deformed, which affects the use effect.

Utility model content

The utility model solves the technical problems that the enamel will fall off when conveying materials, the glass pipeline joints are easy to leak and break, and the cost is high, the plastic layer and the metal layer of the metal-plastic composite pipe are easy to peel off, and the pipe is deformed. For this reason, the utility model provides a sun protection reinforced PE pipe, which has the advantages of convenience and flexibility when connecting pipelines, no peeling and deformation between the PE pipe and the metal pipe, improved work efficiency, and wide application range.

In order to achieve the above object, the utility model adopts the following technical solutions.

A sun-proof reinforced PE pipe, the inner pipe is a PE pipe, the outer pipe is a metal pipe, and the end of the PE pipe is provided with an integrally formed PE flange; Lan; the outside of the metal pipe is provided with a gasket and a clamp for pressing the gasket.

A backing ring can also be provided between the PE flange and the metal flange. The backing ring can be a rubber backing ring, and the rubber backing ring can prevent the PE flange from being damaged during the use of the sun-proof reinforced PE pipe.

Bolt holes can be provided on the metal flange, and bolts can be used for quick connection.

The sun protection reinforced PE pipe can be a straight pipe, a bent pipe or a tee.

The clamp can effectively prevent the deformation of the pipe and the peeling of the PE pipe and the metal pipe. Gaskets prevent pipes from being damaged due to local stress. According to the use environment, several gaskets and clamps for pressing the gaskets can be arranged on the sunscreen reinforced PE pipe. Gaskets and clamps for compressing gaskets reinforce the metal pipe locally, enhance the local strength of the pipeline, and indirectly reduce the cost of the pipeline.

PE pipe is polyethylene pipe, which has the following characteristics: good sanitation, self-cleaning and antibacterial, long-term use without scaling, and solves the secondary pollution of drinking water; resistance to various chemical media, no electrochemical corrosion; smooth inner wall, friction The coefficient is low, the flow capacity of the medium is improved accordingly, and it has excellent wear resistance; flexibility, high impact strength, strong shock resistance and distortion; light weight, convenient transportation and installation; simple connection process, convenient construction, and low overall engineering cost ; Long service life, up to 50 years.

The PE pipe is covered with a metal pipe as a support, and the PE pipe is surrounded by a metal casing, which can be used outdoors for a long time. The pipelines are connected by flanges, and can be assembled into pipe fittings such as tees or elbows, which are suitable for the connection of complex pipelines. When the PE pipe protrudes from the metal pipe or metal pipe fittings, the two ends are melted with hot air for edge treatment. When the pipeline needs to be connected, it can be connected like other pipeline flanges, and the middle pad screw can be clamped. All these operations can be handled on site, which makes the pipeline connection convenient and flexible, thereby improving work efficiency. The utility model is applicable to pipelines with any diameter.

Beneficial effects of the utility model: the metal pipe is used as the support of the PE pipe, and can effectively prevent the sun from being exposed to the sun. Parts of the metal pipe are reinforced with gaskets and clamps that compress the gaskets to enhance the local strength of the pipeline and reduce the cost of the pipeline. The utility model has the advantages of convenience and flexibility when the pipeline is connected, the PE pipe and the metal pipe are not peeled off or deformed, the working efficiency is improved, and the application range is wide.
