Problems solved by technology

Under high temperature operating conditions, changes such as deflection, warping, creep, and crack growth may occur in the flange, and the stress changes in various parts of the flange are complicated; when there is an external bending moment, the stress characteristics of each part of the flange will also change greatly. Changes, deflections, warping, cracks may exacerbate leaks

Abstract

The invention discloses a system for testing a high-temperature pipeline flange under the action of outer bending moment. The system comprises a left pipeline, a right pipeline, a flange as well as an outer bending moment loading mechanism and a stress testing mechanism, wherein the flange is used for connecting the left pipeline and the right pipeline; the flange is sealed by using a gasket; the left pipeline, the right pipeline and the flange form a flange to-be-tested cavity; the left pipeline is connected with a pump through a valve; the right pipeline is welded to a blind plate; a temperature sensor, a pressure sensor and an electric heating device are arranged inside the flange to-be-tested cavity; a flange leakage testing mechanism is arranged outside the flange; the flange leakage testing mechanism comprises a leakage testing cavity formed by a leakage testing wall in a surrounding manner; an exhaust valve and a bottom flow hole valve are arranged on the leakage testing wall; another temperature sensor and another pressure sensor are arranged inside the leakage testing cavity. The system is accurate in stress testing, high in leakage testing accuracy rate, and relatively high in guiding significance on both scientific research and engineering.

Description

technical field [0001] The invention relates to a flange testing system, in particular to a high-temperature pipeline flange testing system under the action of an external bending moment. Background technique [0002] Flange connection is a commonly used connection method in petrochemical equipment. Because of its advantages of easy disassembly and installation, it is widely used in pressure vessels and pipelines in petrochemical, nuclear power, metallurgy, pharmaceutical and other industries. With the increasingly prominent contradiction between economic development and energy supply, and the rapid development of oil refining and chemical technology, high temperature and high pressure conditions are common in various refining and chemical equipment. Under high temperature operating conditions, changes such as deflection, warping, creep, and crack growth may occur in the flange, and the stress changes in various parts of the flange are complicated; when there is an external ...
