Description

Technical Field

The utility model relates to a pipe wall thickness measurement field, concretely relates to a pipe wall thickness measurement device for pipeline elbow granule erosion model test.

Background

Crude oil and natural gas produced in oil and gas wells often carry a certain amount of sand particles, and even after filtration, the residual sand particles still cause erosion damage to components such as valves, chokes, T-shaped connecting pipes and elbows. The erosion damage of the pipeline components is essentially caused by the fact that the oil and gas conveying direction is suddenly changed or the flow is limited, and the motion state of sand particles cannot be consistent with a changed flow field in a very short time due to inertia and then collide with the pipe wall. Impact damage of sand particles is likely to cause thinning and cracking of oil pipelines through long-term accumulation effect, and reliability of equipment is reduced. Therefore, developing a particle erosion model test for the pipeline process component is an important means for revealing the distribution rule and the motion characteristic of particles in the pipeline fluid and the overall damage characteristic of the process component. One of the key links in developing the model test of the problem is to measure the thickness of the tube wall, so as to obtain the erosion strength of the particles. Therefore, a thickness measurement method with high precision and good reliability is required. According to the existing technology for measuring the thickness of the pipeline elbow, a probe of a general handheld ultrasonic thickness gauge is directly positioned and measured on an elbow test piece, the mode enables the determination of a thickness measuring position to have strong subjectivity and randomness on one hand, and the mode of the probe on the other hand enables the probe and a contact surface of the test piece to easily slide, so that the measurement error is increased.
