Corrugated pipe with anticorrosion and anti-wear effects

Abstract

The invention discloses a corrugated pipe with anti-corrosion and wear-resisting effect. layer, the inner side of the polyethylene anticorrosion layer is bonded with an epoxy resin anticorrosion layer, the inner side of the epoxy resin anticorrosion layer is bonded with a polytetrafluoroethylene anticorrosion layer, and the inner wall of the polytetrafluoroethylene anticorrosion layer is coated with Covered with a waterproof layer, the outer tube includes a rubber layer, the inner side of the rubber layer is provided with a fireproof layer, the outer side of the rubber layer is provided with a steel ring layer, and the outer side of the steel ring layer is coated with silicone heat-resistant top coat. The corrugated pipe with anti-corrosion and wear-resistant effect, through the improvement of the inner pipe, under the action of polyethylene anti-corrosion layer, epoxy resin anti-corrosion layer, polytetrafluoroethylene anti-corrosion layer and waterproof layer, the bellows has anti-corrosion effect , to avoid corrosion after long-term use, and improve the service life of the bellows.

Description

technical field [0001] The invention relates to the technical field of corrugated pipes, in particular to a corrugated pipe with anti-corrosion and wear-resistant effects. Background technique [0002] Bellows refers to a tubular elastic sensitive element connected by foldable corrugated sheets along the direction of folding and stretching. Bellows are widely used in instruments and meters, and their main purpose is as a measuring element of a pressure measuring instrument to convert pressure into displacement or force. The bellows has a thinner wall and higher sensitivity, and the measurement range is tens of Pa to tens of MPa. Its open end is fixed, and the sealed end is in a free state, and the auxiliary coil spring or reed is used to increase the elasticity. When working, under the action of internal pressure, it is elongated along the length of the pipe, so that the movable end produces a displacement that has a certain relationship with the pressure. The movable end...
