Abstract

The invention discloses a Teflon pipeline with double composite steel liners. The Teflon pipeline comprises a steel pipe and a Teflon pipeline body. An intermediate layer is hot-melted between the steel pipe and the Teflon pipeline body, and flanges are disposed at two ends of the steel pipe. The Teflon pipeline is both positive-pressure resistance and negative-pressure resistance, the shortcoming that a conventional Teflon pipeline with the steel liners is not resistant to negative pressure is overcome, reliability of products in use is guaranteed, and broad development prospect and social and economy benefits are achieved.

Description

A kind of two-layer compound steel lining tetrafluoro pipeline
Technical field
Patent of the present invention relates to new material technology field, is specifically related to a kind of two-layer compound steel lining tetrafluoro pipeline.
Background technique
Steel lining tetrafluoro pipeline is widely used in the industries such as chemical industry, metallurgy, mine, the energy, pharmacy now, original conventional steel lining tetrafluoro pipe is to utilize compound steel pipe and the tetrafluoro conduits fused of making of stress, there is decay resistance and resistance to malleation, and do not possess high temperature resistant and resistance to negative pressure performance.
Summary of the invention
The object of invention: the object of the invention is in order to make up the deficiencies in the prior art, a kind of two-layer compound steel lining tetrafluoro pipeline of resistance to negative pressure is provided.
The technical solution used in the present invention: a kind of two-layer compound steel lining tetrafluoro pipeline, comprises steel pipe and tetrafluoro pipeline, mesosphere together with described steel pipe is molten with tetrafluoro pipeline intermediate heat, described steel pipe two ends mounting flange.
Beneficial effect: the invention provides a kind of two-layer compound steel lining tetrafluoro pipeline, it is resistance to malleation ability negative pressure again, the shortcoming that has overcome traditional not resistance to negative pressure of steel lining tetrafluoro pipeline, product safety and reliability are guaranteed, and have DEVELOPMENT PROSPECT and social economic benefit widely.
Brief description of the drawings
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the invention is described in detail:
A kind of two-layer compound steel lining tetrafluoro pipeline, comprises steel pipe 1 and tetrafluoro pipeline 3, and described steel pipe 1 is mesosphere 4 together with hot melt in the middle of tetrafluoro pipeline 3, described steel pipe 1 two ends mounting flange 2; To one mesosphere of steel pipe 1 inner wall hot melt, this mesosphere can be fused to steel, again the fusible PTFE that is connected to, after tetrafluoro pipeline 3 is compound, by steel pipe 1 is heated, when mesosphere 4 and tetrafluoro pipeline 3 weldable temperature are when suitable, form by the inwall cooling and shaping that pressurizes.
The above is only the preferred embodiment of the present invention; be noted that for those skilled in the art; under the premise without departing from the principles of the invention, can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
