Steel pipe with noise reduction structure and manufacturing method thereof

Abstract

The invention discloses a steel pipe with a noise reduction structure and a manufacturing method thereof. The steel pipe with the noise reduction structure comprises a steel pipe body, heat preservation pipes are arranged at the two ends of the outer wall of the steel pipe body in a penetrating and inserting mode, heat preservation layers are embedded in the middles of the outer walls of the two heat preservation pipes, and blocking pieces are arranged on the outer walls of the two heat preservation pipes in a clamped mode; and positioning rings are clamped to one ends of the outer walls of the two heat preservation pipes correspondingly, and sliding rods are fixedly arranged in the middles of the outer walls of the two positioning rings correspondingly. According to the steel pipe with the noise reduction structure and the manufacturing method thereof, fixing rods are fixedly arranged on the two sides of the inner walls of two protective sleeves, the two positioning rings are fixed toone ends of the fixing rods, and the positioning rings are clamped at the two ends of the outer walls of the heat preservation pipes, so that when flowing liquid or gas is conveyed through the steelpipe body, the outer wall plays a role in silencing, sound leakage is reduced through air isolation on the outer side, the protection effect is achieved, the outer wall of the steel pipe is not proneto being polluted, and rusting and corrosion of the outer wall of the steel pipe are avoided.

Description

technical field [0001] The invention relates to a steel pipe with a sound-absorbing structure and a manufacturing method thereof, in particular to a steel pipe with a sound-absorbing structure and a manufacturing method thereof, and belongs to the technical field of steel pipes. Background technique [0002] Steel pipe is a common transmission tool, so it needs to play the role of heat preservation, shock absorption and noise reduction during the transmission process. Among them, the performance of high temperature resistance, low temperature resistance and corrosion resistance of seamless steel pipe is not comparable to other steel pipes, so Steel tubes are widely used in petroleum, chemical, electric power, boiler and other industries. [0003] In the prior art, when the steel pipe transports liquid or gas and needs to be silenced, the outer wall of the steel pipe is usually wrapped with sound insulation cotton to achieve the sound insulation effect. On the one hand, long...
