Abstract

The invention discloses a novel high-temperature-resistant high-pressure-resistant and corrosion-resistant PTFE expansion joint which comprises a left flange, a right flange, stainless steel connecting rods, a corrugated pipe, a PTFE lining plate and an abrasion-resistant layer. The flanges are arranged at the left and right ends of the corrugated pipe correspondingly. Lug plates are arranged on the outer side walls of the flanges at the left and right ends and provided with flange holes. The lug plates are connected through the stainless steel connecting rods. The PTFE lining plate is embedded in the inner wall of the corrugated pipe. The abrasion-resistant layer is sprayed to the outer wall of the corrugated pipe. The novel high-temperature-resistant high-pressure-resistant and corrosion-resistant PTFE expansion joint has the beneficial effects of being resistant to high temperatures and high pressure, reliable in work, compact in structure, high in compensation capacity, resistant to corrosion of various media, long in service life and the like.

Description

technical field [0001] The invention relates to the technical field of pipeline compensation equipment, in particular to a novel high-temperature, high-pressure and anti-corrosion tetrafluoro expansion joint. Background technique [0002] Expansion joints are customarily called expansion joints, which are composed of bellows (an elastic element) that constitutes the main body of its work and accessories such as end pipes, brackets, flanges, and conduits, and belong to a compensation element. Utilize the effective expansion and contraction deformation of the bellows of its working body to absorb the dimensional changes of pipelines, conduits, containers, etc. caused by thermal expansion and contraction, or compensate the axial, lateral and angular displacement of pipelines, conduits, containers, etc. It can also be used for noise reduction and vibration reduction. It is widely used in modern industry. In heating, in order to prevent the pipe from being deformed or damaged d...
