Abstract

This invention relates to one high pressure heat exchanger flushing erosion testament measurement method, which is characterized by the measurement in water medium, high speed and temperature and pressure. The method comprises the following steps: firstly flushing testament point selection with speed at 1.9-4.5m / s and temperature as 180-300DEG C and pressure as 2-6MPa, pH value as 7-9.5; Measuring flushing specimen for erosion, surface film, micro organization, flushing front and back different part stress status and rough degree.

Description

technical field [0001] The invention relates to a measurement method for the erosion corrosion test of a high-pressure heater heat exchange tube, in particular to a measurement method for the erosion corrosion experiment of a high-pressure heater heat exchange tube under high temperature and high pressure conditions, which can be used in the field of nuclear power and thermoelectric equipment manufacturing . Background technique [0002] Erosion corrosion is a kind of local corrosion with great harm. It is much more serious than simple corrosion and simple mechanical wear. When equipment is subjected to erosion corrosion, it will accelerate the damage of equipment, and the service life of equipment will be greatly shortened. [0003] With the increasing investment in the construction of nuclear power plants and thermal power plants at home and abroad, the research on related equipment of nuclear power plants and thermal power plants at home and abroad is also in-depth.
