Technical Field

The invention belongs to the technical field of pipeline protection, and particularly relates to a protection device for a gas pipeline.

Background

The gas pipe is a special pipeline for conveying combustible gas, is a rubber hose with a metal gas pipe hose instead of a traditional buckle mode, and can overcome the defects that the rubber hose is easy to fall off, age and bite insects and has short service life.

The gas pipe has the characteristics of convenient installation, reliable connection, corrosion resistance, no gas blockage, good flexibility, long service life, capability of being bent at will without deformation, no gas blockage and the like. The surface soft protective layer material has the characteristics of safety, easier cleaning and attractive appearance, and the service life of the stainless steel threaded connection metal hose is 8 years.

The PE gas pipe is in the municipal pipe market in China, the plastic pipeline is developing steadily, the PE gas pipe, the PP-R gas pipe and the UPVC gas pipe all occupy a place, the strong development of the PE pipe is most remarkable, and the PE gas pipe is wide in application field.

At present, when the gas pipeline is used in a severe environment, a protective layer is additionally arranged outside the gas pipeline, at present, a common protective layer is mainly formed by directly adopting a detachable ring pipe, the sleeve pipe is mainly made of a hard material, the sleeve pipe needs to be matched with the gas pipeline when in use, the length of the sleeve pipe needs to be matched with the gas pipeline in length, the sleeve pipe cannot be conveniently adjusted, and the sleeve pipe cannot be matched with the gas pipelines with different diameters at the same time.
