Problems solved by technology

[0008] Disadvantages of the methods known from the prior art in particular that they are very complex
Moreover, another disadvantage of the above method is that inherently introduces a certain variation in the geometry of the tube, i.e. the cross-section deviates from an ideal circular shape, or the cross-section exacerbates in the longitudinal direction from perfect homogeneity and thus the lumen profile deviates from the ideal form

Embodiment Construction

[0037] figure 1 , 2a , 2b schematically show an exemplary embodiment of a measuring system for flowable, in particular fluid media, which can be inserted into a process line not shown here, such as a line of an industrial plant, and which is configured, for example, as a Corio By means of a mass flow measuring device, a density measuring device, a viscosity measuring device, etc., the measuring system measures and / or monitors in particular at least one physical parameter of the medium, such as mass flow rate, density, viscosity, etc. For this purpose, the measuring system here embodied as an in-line measuring device in a compact design comprises a measuring transducer MW which is connected to the process pipeline via the inlet port 100+ and the outlet port 100# and serves to detect at least one parameter and transform it into a measurement signal representing it. During operation, the medium to be measured (such as low-viscosity liquids and / or high-viscosity pastes) flows ac...

Abstract

The invention relates to a method for trimming a pipe (11), which has at least one reinforcement body (151) mounted on the pipe wall thereof, to a target bending stiffness, wherein the pipe initially has an interim bending stiffness greater than the target bending stiffness. In order to reduce the interim bending stiffness of the pipe to the target bending stiffness, according to the method partial volumes (151') of the reinforcement body (151) are ablated, for example by means of a laser.

Description

technical field [0001] The invention relates to a method for trimming tubes, in particular used as measuring tubes of vibratory measuring transducers, to a predeterminable target bending stiffness. Background technique [0002] In industrial measurement technology, especially also in connection with the control and monitoring of automated manufacturing processes, for the determination of characteristic measured variables of media such as liquids and / or gases flowing in process pipes, such as pipelines, measuring systems are often used which Reaction forces such as Coriolis forces are induced in the flowing medium by means of the vibrating measuring transducer and the transmitter electrically connected thereto (often transmitter electronics housed in a separate electronics housing), and Measured values ​​such as mass flow rate, density, viscosity or some other process parameter correspondingly representing at least one measured variable are repeatedly generated from these rea...
