Problems solved by technology

General thermomechanical analyzers can only test block or strip samples. For samples with complex shapes such as pipes, especially anisotropic samples, because the center position is difficult to determine and fix, thermomechanical analyzers in the related art It is difficult to test samples with complex shapes

Abstract

The invention discloses a bracket for measuring the thermal expansion coefficient of a pipe and equipment for measuring a thermal expansion coefficient. The bracket comprises a base and a tray; the base has an installation position which is connected with the push rod of the equipment for measuring the thermal expansion coefficient; the tray is connected with the base; and the tray has an arc-shaped supporting surface used for supporting a sample to be tested. According to the bracket of the invention, the arc-shaped supporting surface is used for supporting a pipe sample, so that the pipe sample can be tested; the automatic centering of the sample can be achieved through gravity; the problem that a pipe sample placed on a plane in a common needle penetration method is unstable is solved;due to the limitation of the arc-shaped supporting surface, the sample is easier to fix and not prone to displacement in a testing process; and the bracket can be positioned through the push rod of the equipment, and therefore, design and replacement cost is low.

Description

technical field [0001] The application belongs to the technical field of thermal physical property testing of materials, and in particular relates to a bracket for measuring the thermal expansion coefficient of pipes and equipment for measuring the thermal expansion coefficient of pipes. Background technique [0002] Any substance has a certain volume at a certain temperature and pressure. When the temperature changes, the volume of the substance changes accordingly. The increase in the volume or length of a substance as the temperature increases is called thermal expansion. Thermal expansion coefficient is one of the main physical properties of materials, and it is an important indicator to measure the thermal stability of materials. In the field of material science, the measurement of thermal expansion and coefficient of expansion of different materials has always been a relatively important topic, which is of great significance for the study of thermal properties of mat...
